Leap of Faith, No Train in Vain As many of the cities and countries hit hardest, and earliest, by COVID-19 are reopening for business— including Germany, which I was fortunate enough to visit a couple years back—I can’t help but wonder what life’s going to be like moving forward. First, will we see tourism return in the waves that once roiled?

Will new social distancing requirements change the way we gather and mingle in public spaces?

Nostalgically, as I write this, I’m pining for a stein of König Ludwig Dunkel—a beverage I enjoyed in the Hackescher Markt in East Berlin’s Mitte neighborhood. Literally a step out the door of the eponymous station of city’s “S Bahn” elevated train line, the vibrant, people-filled plaza, which also hosts a kind of pop-up market, quickly became a favorite spot. I think I was attracted to the place for many reasons— lots of shops and restaurants refitted into the station itself; a mix of trees and vegetation; and tons of historic brick and pavers everywhere—no asphalt or acres of concrete!

In this issue’s Product Developments’ section, we hit on a number of topics relating to net-zero design, including green infrastructure, adaptive reuse and urban management.

I have to say, I was really surprised how much I loved East Berlin as a whole. Likely, it was the whole behind the “Iron Curtain” vibe, but the city was, frankly, coming alive with reconstruction and new developments after being mostly dormant since WWII. I also loved its edginess. There was artistic graffiti everywhere, including a cool tribute to Anne Frank, as younger people have flocked into these burgeoning neighborhoods, for its somewhat Bohemian, if at least, eclectic, nature. For example, all along the S Bahn, shops added sprinkle to an otherwise utilitarian corridor. One really surprised me— “Mittelicht”—a high-end LED luminaires store—you can take the lighting nerd out the country …

This street scene, triggered by a random photo in a news story about Germany reopening, reminded me of this neighborhood, and I just couldn’t help making a stroll down memory lane, aided by Google Satellite, a tool that’s both fantastic, and a little Big Brother scary. Did I mention the street was paved in permeable stone? This was good, because it rained almost all the time…

As the U.S., too, begins to emerge from this debilitating pestilence, a fog of uncertainty remains.

But there are many lessons we can learn from old

Berlin, Germany

Berlin, which was, in many ways, starting from scratch. If the cards dealt us demand a “do over,” we should do it right. Like so many things of the past, the rediscovery of good ideas, like permeable surfaces, and lots of trees, are good ideas, period.

In this issue’s Product Developments’ section, we hit on a number of topics relating to net zero design, including green infrastructure and urban management.

Another lesson to learn is that “we are all in this together.” This was a lesson communicated so clearly to me as the reason I was behind the Berlin Wall in the first place—Velux’ biennial daylight symposium. It was such a great event, and I walked away with a lasting sense of entente. So many people congregated from all over the world to truly make an effort to make our global community a better place.

It makes me sad to wonder if such international gatherings may dwindle amid fears of further devastating viral outbreaks. I count myself blessed that I was able to sneak away to London right at the beginning of this year, and once again, disembarking at another historic train station—St. Pancras/ King’s Cross—I strolled into the heart of another terrific urban redevelopment, which included Google’s ginormous, under-construction landscraper, which itself, was just down the lane from a Victorian-era coal yard that was transformed into a mall—something even this shopping curmudgeon could enjoy.

We’ve all had to learn new, mostly remote, digital ways to work these past months. Let’s not let fear— and physical limitations—stop the flow of knowledge of the world community. We need an Age of Enlightenment, not another Dark Age.

BEST PRACTICES IN RESTROOM HYGIENE

In response to the rapid spread of COVID-19, the experts at Bradley Corp. offer the following advice to keep restrooms clean.

Post signage with reminders about washing hands for 20 seconds per Centers for Disease Control (CDC) guidelines, maintaining safe distances between users and throwing away paper towels, etc.

Offer touchless fixtures. Cross contamination of germs in restrooms can be reduced by using touch-free fixtures for everything from soap, faucets, hand dryers/towels, doors and flushers.

Increase cleaning, sanitization and restocking.

Proper and frequent cleaning and disinfection is key for restrooms, especially for high-touch surfaces such as doorknobs, faucets, sinks, toilets, stall door openers and paper towel dispensers.

Provide trash cans and hand sanitizer near exits.

“Our research shows that 65% of Americans use paper toweling to avoid contact with restroom doors and faucets,” says Jon Dommisse, director of strategy and corporate development, Bradley Corp.

“Keeping paper towels and waste containers near doorways can be helpful so people can throw them away upon exiting.”

Prop open doors to increase visibility and minimize contact. To limit the number of people in restrooms and encourage social distancing, a propped open door can give people a small window into seeing how many others are already inside. In addition, a slightly opened door allows people to maneuver the door with their elbow, instead of hands.

LED Lighting & Controls

Reducing Jet Lag, Improving Reviews with Lighting Design A study by the Hotel School at the SC Johnson College of Business at Cornell University—which included more than 95,000 online reviews and ratings for 99 independent, high-end hotels—reported that guests cited a comfortable room as the most important quality of a hotel stay.

Yet, many hotels fall short. One perennial complaint: poor sleep. Research shows 80% of travelers have trouble sleeping. The No. 1 cause? A “different environment.” LED lights and controls can help.

LED lights and controls are now go-to solutions for making hospitality spaces look good and its guests feel good.

Lighting has long been instrumental in showcasing unique artwork and vernacular architecture.

It gives a distinctive character to restaurants and lounges, the right touch of flair to hallways and lobbies, and Instagram-worthy radiance to pools and patios. Cold, dingy suites come to life under a warm, inviting glow. With today’s high-tech controls, LEDs’ color rendering customization is also unrivaled.

But those same controls can now do more than drape rooms with alternating colors with the push of a button. It can help improve guests’ health, enhance their mood, reduce jet lag and make different places feel more like home.

Consider the power of light, reported by Steven W. Lockley, Assoc. Professor of Medicine at Harvard Medical School: “Light can be a stimulant, directly alerting the brain or promoting sleep before

bedtime, depending on the spectrum and intensity of light exposure. Having greater control of light exposure when traveling can help promote sleep at the right time or wake at the right time, preserving some sense of sleep normalcy when on the road.”

By taking steps to improve the perceptions of comfort and help guests get a good night’s sleep, hotels can increase customer satisfaction, generate stronger online reviews and create more business and sales.

Enter tunable white light, which is light that complements our natural circadian rhythms and mimics the sun. The technology adjusts to our daily rhythms by automatically changing the intensity and color temperature of a space’s interior lights throughout the day. Brighter, cooler-toned lighting, especially at a high intensity, stimulates alertness and improves cognitive function by suppressing the sleep hormone melatonin. Dimmer, warmer-toned light does the opposite. It encourages melatonin secretion and helps guests relax.

One way to implement color-tuning light systems into a hotel’s existing infrastructure is to replicate what InterContinental Hotels Group (IHG) did in some of the rooms at its Crowne Plaza Atlanta Airport: install mobile bedside light fixtures that double as task lighting. This allowed guests to reinforce the local sunrise and sundown patterns with blueenriched light in the day and amber light in the evening. The lamps are adjustable, so guests can override this setting.

This tactic worked within the confines of existing infrastructure, but a complete design solution would be best in a greenfield project. Such a hotel would

have each guestroom outfitted with a fully tunable light system for the optimal guest experience. Built into the room’s architecture—rather than a bedside add-on—this system would offer hassle-free settings for guests to promote alertness and sleep.

Typical guestroom lighting includes task lighting (at a desk or bedside), mirror lighting, general ambient (windows and overhead fixtures), night lights, closet lighting and perhaps accent lighting. Incorporating tunable white lighting principals into all these lights elevates the room experience.

Ideally, guests should be able to input their desired wake and sleep times and the lighting controls would do the rest with all the lighting in the room. Starting with a dose of bright and cool white light in the morning and warm white light in the evening, the lights would feature automatic and continuous color shifting. This set-it-and-forget-it option allows guests staying from far away to acclimate to local time quickly, or to maintain their native time zone during a short trip.

Guests should also be able to override the system and choose specific settings for their needs or preferences. For example, a default “sleep” setting would not be helpful to someone who needs to work late into the evening.

Whether for health or ambience purposes, the hospitality industry is amid a lighting revolution. LED lights and controls are now go-to solutions for making hospitality spaces look good and its guests feel good. Both generate thumbs-up reviews for hotels and their architects, designers and decorators who constructed these spaces with guests’ top priority in mind: comfort and control.

BETTER ENVIRONMENTS

Color tuning rooms in hotels can help improve guests’ health, enhance their mood, reduce jet lag and make different places feel more like home. Having greater control of light exposure when traveling can help promote sleep at the right time, or wake at the right time, preserving some sense of sleep normalcy when on the road.

Fire-Rated Glazing

What Architects Need to Know about Fire-Rated Glazing Advancements in fire-rated glazing technology have paved the way for exterior fire-rated glazing applications that go beyond typical punched openings and into fully engineered, multi-functional curtainwall systems. These advanced fire-rated glazing systems can perform like the rest of the materials building envelope and even match the aesthetic of adjacent non-rated glazing systems. Here are some considerations for architects specifying exterior fire-rated glazing systems for their projects.

While glass gives the benefit of natural daylight, controlling heat and glare are important considerations, as well.

Lot Line Requirements Fire-rated glazing fulfills the designer’s goals of having unobstructed views, natural light and code compliance in situations where buildings are adjacent to or in close proximity to lot lines. An exterior wall may or may not be allowed to have openings depending on the fire separation distance. When allowed, the codes distinguish between openings that are “protected” (fire-protective doors, windows, shutters) and “unprotected” (no fire rating).

Table 705.8 in the 2012/2015/2018 IBC lay out the percentage of protected and unprotected openings and size limits allowed in exterior walls. Fireprotective glass like ceramics and wired glass tested to NFPA 252/257 are either limited in size or prohibited altogether depending on the fire separation distance. Generally speaking, as the fire separation distance increases, the allowable opening area and the percentage of allowable fire protective openings increases.

However, these limitations do not apply to fireresistive glazing tested to the more stringent ASTM E-119/UL 263 standard, which requires limiting the temperature rise to less than 250º F above ambient on the non-fire side. Designers can use fire-resistive glazing in areas where exterior openings are not permitted or limited in size per IBC Table 705.8. By using fire-resistive glazing, designers don’t have to sacrifice expansive clear views and abundant natural light in order to meet code requirements.

Dynamic Curtainwall Testing Static curtainwall testing performed in a chamber is one way to determine a product’s ability to prevent air and water from entering the building. However, the information from this test is limited. This is why

IN HARMONY

Advanced fire-rated systems can perform like the rest of the materials building envelope and even match the aesthetic of the adjacent non-rated glazing systems. The Orlando VA Medical Center at Lake Nona is pictured above and a two-hour fire resistive rated GPX blast curtainwall to the right.

dynamic curtainwall testing, designed to duplicate real world conditions, is preferred by owners, architects and building-envelope consultants.

Today’s advanced fire-resistive curtainwall systems are tested to AAMA 501.1, ASTM E284 and ASTM E331. In addition to air and water testing, these systems are also tested to AAMA 501.4, ASTM E330, interstory vertical displacement, thermal cycling and condensation evaluation.

Thermal Performance Occupant comfort is a key factor when selecting glazing products for the building envelope. While glass gives the benefit of natural daylight, controlling heat and glare are important considerations, as well. Today’s advanced fire-rated glass products can easily incorporate low-E or any energy-performance glazing. Designers can also find fire-rated glass and framing components in the   database, enabling them to simulate the U-factor, Solar Heat Gain Coefficient (SHGC) and Visual Light Transmission (VLT) of exterior fire-rated glazing assemblies.

Multitasking Protection Against Other Threats Advanced fire-rated glazing systems can multi-task to provide additional protection against various environmental and man-made threats. Fire-rated glazing manufacturers have tested and listed systems that also meet: Florida Product Approval, Texas Department of Insurance and UL certifications for hurricane; Up to UL 752 Level 8 for ballistic; U.S. Department of Defense (DOD) Minimum Antiterrorism Standards for blast; ASTM F-1915 Grade 1-4 for forced entry. 

IAQ and ventilation measures are frequently not at the top of budgets.

Yet many engineers are pointing out that higher humidity levels in buildings, right now, could help prevent the spread of the coronavirus. to my heart, I, indeed, found it hard to think about exemplary—and many times more costly—building measures, when so many are struggling for survival, financially or physically. Yet many stalwart A/E leaders have not given up the rallying cry, adding that it’s now more than ever to amp up the game, as in some ways, the  crisis has put the spotlight on the very poor, overall health of the earth.

For example, in budgeting building systems for most projects, really high-end IAQ and ventilation measures are frequently not at the top of the list. Yet many  engineers are pointing out that higher humidity levels in buildings, right now, can help prevent the spread of the coronavirus. It begs the question, that perhaps as part of COVID prevention, we should be turning to building measures to improve, frankly, the resiliency of people—specifically in context of the air they breathe and water they consume. That said, over these pages, are a number of items ranging from clever adaptive reuse, to water and power conservation, that emphasize how we can trim waste from cycles we too often take for granted.

NATURAL LIGHT, VENTILATION, LIFE SAFETY

Innovation to an Old System Will Save Lives A must-have in any high-performance building design, solar chimneys, which bring in not only natural light, but move outside air passively via stack effect to regulate the temperature of a building, can slash energy costs up to 50%, at virtually no major cost to a building’s construction. Considering that an estimated 19% of the world’s energy resources goes to heating, and cooling buildings, integration of solar chimneys into new construction and retrofits offers great potential for reducing this massive environmental cost.

Now, research reveals the system could also help save lives in a fire. As part of a new building in Melbourne, Australia, the Mentone Reserve Pavilion, researchers from the Royal Melbourne Institute of Technology, working with the city of Kingston, created a solar chimney optimized for both energy saving and fire safety. Modeling (right) shows the system radically increases the amount of time people have to escape the building during a fire—extending the safe evacuation time from about two minutes to more than 14 minutes.

RMIT’s Dr. Long Shi said solar chimneys have well established environmental credentials, but their potential for improving fire safety have not been explored. “In an emergency situation, where every second counts, giving people more time to escape safely is critical,” said Shi, an Australian Research Council DECRA Fellow. “We hope our findings will inspire more investment and development of solar chimneys in Australia, and around the world.”

The new research offers a technical guide by coauthors Anthony Ziem, Jie Li, Professor Kevin Zhang and Professor Sujeeva Setunge.

BETTER BUILDING SYSTEMS

SAVING LIVES

During a fire, the stack principle— that hot air rises— enables the solar chimney to suck smoke out of the building. Less smoke means better visibility, lower temperatures and reduced carbon monoxide—all of which contribute to increasing the amount of time people have to safely evacuate.

“Delivering on two important functions could boost the already strong cost-effectiveness of this sustainable technology.”

Keeping an Eye on Health

IMPROVING COMFORT

The sensor bundles can monitor occupancy, the number of people, temperature (at room and at desk level), noise levels, daylight levels, and even relative humidity.

Keeping employees comfortable and healthy in an office is critical. Employee discomfort, ill health and reduced performance can be linked to a poor-quality office environment. Signify is launching its Philips IoT sensor bundles to collect and deliver data via its Interact Office connected lighting system and environmental monitoring APIs. The sensors enable businesses to monitor office environments and optimize conditions for employee health and wellbeing. Bluetooth enabled, they can provide indoor positioning and navigation capabilities. Bundling and delivering these sensing capabilities into one unit riding on lighting eliminates the need for multiple sensors, and is much more cost effective.

RENEWABLE POWER

Wind in 2019, according to the AWEA, was the No. 1 choice of new utility-scale power generation.

Wind Adds Eco and Economic Benefits

NO BRAINER?

Sectors that would see the most economic benefit would be manufacturing, construction, finance/insurance, transportation and warehousing, and public administration.

But Purdue researchers are quick to add the benefits gained regarding the long-term reduction of greenhouse gas emissions may be more important.

A MIGHTY WIND

A Purdue University study that models increased wind production in 10 states shows significant economic impact in those states, as well as billions of dollars spread over the rest of the country. Led

by Shweta Singh, an assistant professor in the Dept. of Agricultural and Biological Engineering, with colleagues at the University of Sydney, the researchers found that beyond construction activity, the positive economic effects also spill over as shown by the multi-region input output (MRIO) calculations. “In states that get new wind energy capacity, we see significant economic impact, but there is also $3 billion that spills over into the other states because there is so much interdependency on products being manufactured there,” Singh said.

The analysis considers the effects of adding 500 megawatts each in 10 different states that produce the most wind energy in the U.S.—Texas, Iowa, Oklahoma, California, Kansas, Illinois, Minnesota, Oregon, Washington and Colorado. The result would be almost $24 billion in economic impact in those states, as well as an additional $3 billion throughout the rest of the U.S. The U.S. currently has more than 100,000 MW of operating wind capacity, according to the American Wind Energy Assn. Adding 500 MW in 10 states would be only a 5% increase but would have significant economic benefits.

According to the American Wind Energy Assn., in 2019, wind power became the largest source of renewable energy in the U.S., supplying 7.2% of the country’s power.

At the state level, according to AWEA’s Wind Powers America report, wind energy hit remarkable highs. Six states—Iowa, Kansas, Maine, North Dakota, Oklahoma and South Dakota—generated at least 20% of their electricity using wind. Iowa and Kansas both surpassed 40% wind generation, and, more impressively, both states generated more electricity from wind power than any other technology.

Utilities and corporate buyers set yet another record in 2019, signing over 8,700 MW of power purchase agreements. Notably, corporate buyers signed 40% of these agreements, with Walmart and AT&T being the year’s two largest corporate purchasers.

Polycarbonate Barriers Meet New Needs One manufacturer’s quest to reinvent itself in a new COVID-19 world.

As COVID-19 descended upon us and infection numbers began rising in alarming numbers, certain sectors of the building manufacturing industry are taking a good, hard look at their materials, systems and capabilities in an effort to make a helpful contribution to the greater good and remain relevant in this struggling economy.

With clean transparent sheets and barriers in high demand as initially hospitals and healthcare facilities, and now office and retail spaces scramble to establish protection strategies for workers, patients and patrons, polycarbonate and  manufacturer Palram Industries is stepping up.

To meet urgent market needs, Palram began providing transparent polycarbonate sheets in large quantities to subsidiaries who turned the material into face shields. Soon after, the company converted one of their opaque lines to clear  at their eastern Pennsylvania plant.

As the U.S. Army Corps of Engineers kicked into full gear building popup hospitals around the country, Palram’s   for hygienic privacy partitions was a good match. The incorporation of silver ions into the  compound before the extrusion process actively propels microbes away upon surface contact as the ions are transferred into the bacteria where it ceases their mitosis.

The material has been proven to reduce microbial colonies by up to 99.99% within 24 hours.

Pre-COVID-19, Palram and its subsidiaries had been working with banks and post offices in creating separations between service providers and customers, but now the demand is exponentially greater.

With trade shows currently at a standstill, the company is also working to reposition itself within the sign and display market in offering sought-after signage for non-residential facilities now needing to instruct workers and patrons on new requirements, guidelines and wayfinding.

Now that the country is reopening into a new world of social distancing, office and commercial facilities are figuring out how to navigate.

“It’s a new world with new rules. Companies want to enable verbal communication and spatial expression, but they need to create partitions, screens and distancing,” explains Benny Shimshoni, Palram’s Digital Marketing Manager. “This is where transparent partitions are coming to life.”

To assist organizations as they set up protective barriers and signage, Palram has developed useful renderings, for example, waiting area chair pods and dividers, and hand sanitation kiosks that blend into the office/retail design with matching colors and logos. Further, sneeze-guard products are in demand for transparent office partitions at employee desks. www.palram.com CIRCLE 395

CEILING SYSTEMS

Shimmering Relief Approaches to dealing with ceiling spaces deliver not only practical functionality, but outright wonder.

In Amsterdam, nearly 7000 polished aluminum “leaves” turned a renovated office building into a piece of functional art for workers and the community. Formerly empty, the building was transformed by Benthem Crouwel Architects into distinctive, energy-positive offices for the Dutch Charity Lotteries: Goede Doelen Loterijen.

A major goal was to gather the company’s approximately 600 employees—formerly at different branches—into a single location. The new offices also needed to be highly sustainable and communicate the company’s social activities. In addition to offices, the building includes a public restaurant, an auditorium and a TV studio.

Saartje van der Made, partner at Benthem Crouwel Architects, and one of the leading project architects, participated in planning meetings attended by the clients and future users. “Site visits, workshops and creative sessions made it clear that one of the main wishes was to bring the parks at former locations to the new office environment,” she relates. “Combined with the organization’s sustainability ambitions, this inspired us to cover the existing structure with a new roof, a roof that both shelters the employees and brings them all together.”

Light filters through the folded aluminum panels innovated by the designers for the roof. “Roof gardens and terraces with lots of greenery create a space that embodies nature and trees in the middle of the business district,” says van der Made. The roof extends to form an awning over adjacent outdoor areas. Dark, slender, full-height tree-shaped columns, indoors and outside, provide roof support.

The exterior roof’s reflection, visible from afar, changes appearance depending on the time of day. Integrated into the roof are 949 solar panels and a rainwater collection system for green roof irrigation. Materials from the building’s renovation were reused where suitable. New materials were selected for their sustainable and recyclable qualities.

Ceiling Systems

Ceilings Make an Impact A new study shows that ceilings have a far greater visual presence than floors in retail design. A sampling of randomly chosen stores at a new shopping mall showed that a customer’s first view of a store interior reveals, on average, five times as much ceiling area as it does floor area.

The study was conducted in a recently-built open-air mall in Los Angeles. Much of the floor views were blocked by merchandise and displays. The average ceiling, however, was still prominently on display. The findings suggest that the high visibility of ceilings gives them a strong potential to impact the aesthetics of retail environments, as the overhead area can be treated as a designable surface that contributes to customer experience and sales.

CUSTOM FINS

Creating Brand Consistency The new Pilot Coffee Roasters café in downtown Toronto’s Manulife Centre is an example of a brand influencing architecture, and the architecture, in turn, influencing the brand. This was critical for Pilot in creating aesthetic consistency for locations within a series of very different spaces. The Manulife Centre location represents the most evolutionary point of that process to date, with refinements

by Williamson Williamson Architects to branded design elements.

Spatial slats, painted with the lenticular image of an unfolded airplane, create a sense of movement throughout the space. Kernels of previous projects have been adopted, integrated and resized, including staples of white oak, metal detailing and living green walls. “We approach every project by looking beyond the brief to envision the human interaction that is going to take place in a space,” explains Williamson. “The atmosphere of the Pilot spaces has become as important as the quality of their coffee, and our iterative approach has provided brand consistency that is easily adaptable to the neighborhood character of each new location.”

ADAPTIVE REUSE

Capital Idea Reusing its industrial heritage, bridge houses in Amsterdam were transformed into standalone hotel suites.

Reusing existing structures—rather than building anew—according to the Gensler Research Institute’s Impact by Design 2020 report—usually results in lower environmental impact. Studies show that the additional operating efficiency, even of a high-performance building, can take up to 80 years to make up for the impact of having built it in the first place.

Therefore, replacing an existing building should only occur if it cannot be adapted effectively or if the building that replaces it has sufficiently higher energy performance to quickly counterbalance the material loss.

Because of their former function, the bridge houses have panoramic and far-reaching views of the city and its historic canals.

INSIDE-THE-BOX THINKING

Embracing its goal to be the world’s first circular city, SWEETS “Hotel,” in reality, is dotted across Amsterdam in 28 different bridge houses, built on its historic canals. Each bridge house is a stand-alone suite with unique interiors, designed with the idea of the tiny building in mind.

Along these lines, the city of Amsterdam presented its strategy to become the first 100% circular city in the world by 2050. Focus on circularity is inspired on British economist Kate Raworth’s unique “Doughnut Economy.” Within the framework, the performance of an economy is measured by the extent to which the minimum living standards (the inner ring of the doughnut) and the needs of people (the filling of the doughnut) are met without overshooting Earth's ecological ceiling (the outer ring of the doughnut).

AMSTERDAM’S CIRCULAR PLAN

Focus on circularity is inspired by British economist Kate Raworth’s “Doughnut” theory: An economy is measured by the extent to which the minimum living standards (the inner ring) and the needs of people (doughnut filling) are met without overshooting Earth’s ecological ceiling (the outer ring).

Amsterdam, Netherlands

Bridge Houses Transformed into Hotel Rooms Proof, however, is in the pudding, so it is said, and as evidence, one of the fruits of the city’s efforts is the SWEETS Hotel. In reality, the “hotel” is dotted across Amsterdam in 28 different bridge houses, built on its canals. Due to the centralization of bridge control, the bridge houses lost their original purpose of working space for Amsterdam’s bridge keepers. SWEETS Hotel re-uses this industrial heritage by transforming the bridge houses into stand-alone hotel suites with unique interiors, designed with the architectural history of the tiny building in mind.

With building dates between 1673 and 2009, the bridge houses carry an extensive history. Their various architectural styles show how the city developed and grew when new quarters were built and how people thought about city development at that time.

Although the tiny houses—some with a floor size as small as 10.5 m²—were not designed for people to sleep and shower in, the two-person hotel suites are now all equipped with a shower, toilet and pantry.

Two bridge houses are furnished with a kitchen.

Because of their former function and particular

locations, all 28 bridge houses have a panoramic and far-reaching view across the canals of Amsterdam.

Design ‘Picnics’ With respect for the original architects, the interior design team of SWEETS researches and reacts to the architectural history of each individual bridge house.

During so-called “design picnics” on location, together with all the involved partners, the team chooses which elements to preserve and which to play with.

For example, some historical remnants were found during the renovation process of bridge house ‘Amstelschutsluis’ (built in 1673). The hotel’s design team kept these remnants intact as much as possible.

For the interior of bridge house “Hortusbrug,” a tiny

architectural icon in the style of “De Stijl,” the design team took their inspiration from famous Dutch architect and designer Gerrit Rietveld, playing with typical Rietveld-elements while respecting his legacy.

Exploring Different Neighborhoods SWEETS officially opened the first 11 bridge houses in March 2018. Ten have been added since and the remaining seven will be completed before the end of 2021. Past February, SWEETS hotel was awarded “Hotel of the Year 2020” at the annual Frame Awards.

Earlier, the hotel won the Dezeen Award 2019 in the category “Hotel and Short-stay Interior” and the Entree Award 2018 for the “Best Hotel Concept.”

LIGHTING DESIGNER PROFILE

Invoking Emotion Within architecture, lighting design blends engineering and artistry. Good lighting design can encourage wellness, evoke emotion and change behavior in the built environment. In context of understanding an integrated lighting designer’s role in an architecture firm, according to Pernille Bech-Larsen, who holds such a role with Danish architects Henning Larsen, they work in the balance between aesthetic and technical considerations. “My priority is to make sure that the lighting design complements the architectural vision, rather than looking like an afterthought,” says Bech-Larsen.

The firm is somewhat unusual in its approach to lighting because not many firms have in-house lighting designers. This, she says, enables it to consider

lighting setups in the early stages of the process, and especially allows the designers to make sure that both daylight and artificial lighting work in tandem, instead of adapting to an existing concept and structure. Light, she adds, is a storytelling tool to add emotion; consider, for example, the way that a certain smell might remind you of your grandparents’ home.

“You can use this to brand a building and to make it stand out, but you can also use it to guide people’s attention and behavior in interior spaces. It’s all about using light to remind users of conditions they know, but perhaps have never thought about, and create a link with the behaviors they associate with those spaces, says Bech-Larsen. “We try to create different situations and moods, such as by using lower-height,

small-scale lighting for a more focused, human-scale environment.”

It’s a good time to be a lighting designer, she says, in that the industry is recognizing how important good lighting, and especially daylight, is to the people inside a building. “We know daylight is restorative to humans. But our modern lifestyles can make it hard to get exposure to natural light. Artificial light comes in when we’re exploring how we can improve indoor life in the absence of daylight. We cannot ignore artificial lighting. There are so many situations where it is simply not possible to get enough light without it, and so we must consider the nuances and applications of artificial lighting. It is an important tool in creating beautiful, practical and healthful environments.”

Deep-Sea Inspiration Overhead

When Young H Design began planning for the Mark Fairwhale offices in Shanghai, they were careful to create an image of strength and savvy.

The company’s headquarters functions as a flexible working space, which reflects the company’s cutting-edge style, with an unexpected graphic twist. Founded in 2001 by Mark Cheung, the firm’s stylish collections of apparel and accessories are currently sold in its 900 stores around China. Each letter in the name “Fair Whale” has a specific meaning. Founder Cheung devised his corporate theme around “fair,” in context of beauty and elegance: F stands for fly; A, amenity; I, intelligence; R, responsibility. “Whale” stands for the awesome sight of the whale surfacing from the depths of the sea; W, will; H, harmony; A, adolescence; L, love; and E, envision.

While it is not unusual for firms to display various corporate images executed as posters, photos, artworks, or even news of technical accomplishments on walls in public spaces in their offices, that’s not the only case at Mark Fairwhale. Here, they are on the ceiling as well, in the form of illuminated LED outlines of full or partial views of whales, along with the company logo.

For visual emphasis, there is a wall-spanning panorama of a family of whales that appears behind the first floor reception desk. But it is the creative utilization of overhead space with whale-themed humor and artistry that gives the environment its own distinctive voice.

Led by design director Antonio Berton, the Young H architecture and interiors team scaled the

three-floor, 104,000-sq.-ft. spaces, completed in early 2020, to fit the needs of the designers, marketers and support staff. Ceiling heights are 30 ft. in the atrium and 15 ft. in the worker areas. The Young H specialists designed all the different elements of the ceiling, including the lighting, which is formed of LEDs with a white metal shell, and silicone semitransparent cover. Fabricator for the custom system was the local advertising specialty firm of ELI Manufacture.

On the first floor is a welcoming area for guests, with the reception desk and a nearby cafeteria with counters shaped as jumping whales. On an upper level, a floor-to-ceiling sculptural element of uniform slats is molded into a wave-like pattern above an informal seating area.

WORTHY INVESTMENTS “LED upgrades are typically driven by a perception that light is a commodity to be obtained at the lowest cost. This places an emphasis on energy efficiency and energy cost savings, which is appropriate but should not result in missed opportunities to costeffectively add value. While light is indeed a commodity, lighting—the application of light to spaces—can be an asset, supporting organizational goals by providing accurate colors, visual comfort and enhanced space perception.

Exterior Lighting Aids Net-Zero Effort Student safety and zero net energy initiative drive exterior lighting design at California campus.

Plaza Verde is a housing complex on the University of California Irvine (UCI) campus. KTGY Architecture + Planning was commissioned to design the complex to connect east campus housing with the main institutional buildings.

Illuminating the way are Luminis’ Lumistik CL821 columns.

“Security—real and perceived—is always a key consideration for undergraduate student housing,” said Benjamin Kasdan, associate principal at KTGY. “The goal

is to ensure the resident students feel safe, but also to reassure their parents.”

To this end, transparency is an intentional design element, inside the buildings and out. All structures have breezeways on the main floors so pedestrians always have a clear visual path through the various buildings and across the courtyards.

Lighting, too, is a significant contributor to that wayfinding, illuminating courtyards with

bright, yet comfortable light. A 20-ft. vertical grade change required some special considerations, including sloped pathways to ensure accessibility. The clear lens of the Lumistik provides a wide distribution of light along the path and surrounding area, enabling students to safely navigate the elevation changes.

One of the key accomplishments of this massive project was designing to net-zero energy standards.

Consuming only 48W,

the luminaires deliver a robust 88 lm/W, with an expected lifetime beyond 50,000 hours.

“The exterior lighting is a seamless element in the project,” said Kasdan. “It was a truly collaborative effort, as everyone worked well to blend all the elements. You can’t tell where the architecture ends and the interior design or landscaping begins. Lighting is a part of that.”

FLEXIBLE LIGHTING

New Way to Work?

“Bookable” shared satellite office spaces require flexible infrastructure.

Scandinavia is seen as a pioneer for good work culture, but given the impact of the COVID-19 virus, and the effectiveness of “work away from work,” Fabege, one of Sweden’s largest property companies, set out to develop an office concept beyond most models.

Its reservable satellite offices are spatially detached from the main office, a new idea that reveals benefits for the individual and for social coexistence.

Three locations, across Stockholm, were created and equipped with flexible downlights for a track. The concept moves away from traditional approaches.

“I wanted to avoid carpets of light at all costs,” said Joaquim de Abreu, WAW’s lighting designer. “So we subdivided the room area into different zones and use light only as strongly as needed. The light adapts to the intended environment,” he continued. This called for a flexible track infrastructure and luminaires with high visual comfort and intuitive control. In addition to ERCO spotlights and pendant luminaires, he specified the company’s Jilly fixture (below) as the downlight for track. All luminaires can be controlled wirelessly. www.erco.com CIRCLE 384

 WAW created a dramatic

lighting setting with strong accentuation. Using ERCO’s Jilly fixtures, flexible and efficient workplace lighting was created. Installed above long conference tables and individual workstations, the downlight scores points with high visual comfort.

Making it Work: In converting public assembly spaces to alternate care facilities, the U.S. healthcare system is better equipped to provide COVID-19 patient care.

By Barbara Horwitz-Bennett, contributing writer

Generating an acute healthcare crisis of dramatic proportion, COVID-19 has created an unprecedented surge in capacity.

In rapid response, the U.S. Army Corps of Engineers systematically evaluated 601 U.S. arenas and 551 hotels and dormitories before awarding contracts to convert 21 arenas and 16 hotels/dorms into alternate care facilities.

As the design and construction industry takes a deep dive into the world of repurposing existing facilities into treatment centers, A/E firms are actively putting out expert content and guidelines to help healthcare organizations struggling to find new spaces for patient care with existing healthcare facilities over capacity.

“It would be very difficult, if not impossible without time-consuming major renovations, to convert and renovate a public assembly space into a fully operational hospital that meets all licensing and compliance requirements,” states HKS

in a concept study, “COVID-19 Conversions: Public Assembly Spaces to Hospitals,” in collaboration with MEP firm Mazzetti.

Consequently, the focus has been to reutilize building stock as much as possible and only redesign where necessary.

What follows is a collection of key design issues and considerations that must be addressed in evaluating hotels, dormitories, arenas, convention centers and schools for these conversions.

Hotels Of the facility types available for conversion, hotels are perhaps the most suitable with individual rooms and private bathrooms, in addition to technology infrastructure and food service.

At the same time, Russ Murdock, vice president/ convention center practice director, Henderson Engineers, Shawnee, Kansas, points out that hotels typically utilize recirculating room units with minimal outdoor air and do not possess the exhaust air capability at the level required for infectious disease rooms. To address this, the exhaust systems can be upgraded or an exhaust fan with a  filter could be extended out of the sidewall or window, and balanced to maintain a negative pressure in the room.

For non-acute and common areas, Douglas King, principal, Stantec, Chicago, says there should be at least one change of air per hour. For acute patient areas, the target should be 5 to 10 air changes per hour. However, for patients on ventilators, the Centers for Disease Control and Prevention requires 12 or more air changes per hour.

Another redesign issue is the incorporation of medical gas. Murdock recommends a piped oxygen system which involves a bulk tank, vaporizer and pipe system stored on site and routed through the corridor and into the rooms. Alternatively, a bottle oxygen system can be provided.

Convention Centers and Arenas Designed as flexible, convertible, multi-purpose spaces, convention centers and arenas are well suited for medical conversions. HKS/Mazzetti list a number of attributes that make them efficient as large-scale care facilities: they’re flexible spaces that maximize efficiency of patient care configurations; provide ample utilities to support care, including ventilation, electricity, compressed air, water and drains; feature the convenience of loading dock access and staff support for quick set up; similarly, they have large back-of-house support spaces that ease vehicular and transit access; and finally, the structural ability to accommodate high weight loads.

Henderson adds that convention center  systems are often zoned by divisible space and designed to accommodate significant outside air volumes. Similarly, he notes, exhibit hall areas often contain highly customizable utility boxes with 100A of power at 208Y/120V—three phase—in addition to non-potable water service, drains, compressed air, and low-voltage copper/fiber connectivity.

“Configured as a temporary healthcare facility, the utility boxes would be the hub for the electrical needs, with a capacity to serve significant numbers of patient stations, or bed line-ups, depending on the configuration,” says Henderson, adding the fiber/ copper connectivity can be used to create local monitoring and networking capability, as could the presence of WiFi and DAS systems.

That said, the HKS/Mazzetti team suggests that additional electrical distribution might be required in arena settings, as well as additional power for medical equipment and other patient care needs. While

TESTING SOLUTIONS The COVID Shield is a modular, scalable, customizable testing solution that could be placed on college campuses, outside workplaces, in community areas and numerous other settings. As the world evolves its response to the COVID-19 pandemic, one clear reality is testing for the virus will be part of our daily lives for the foreseeable future. The COVID Shield can be assembled as a single unit or connected to others, to form a modular pavilion of testing stations. Its flexibility and easy alteration allow it to adapt to fast-changing testing protocols, and a variety of site footprints. A key advantage of the shield is how easily it can display printed art or advertising.

convention centers often have diesel generator emergency power systems, arenas may need to consider provisions for standby emergency power for specific loads critical to patient care. Whereas hotels offer private bathrooms, convention centers and arenas may need to include portable toilets and showers as close to the beds as possible.

Lighting is another consideration as arenas are limited to covering large areas with the same light levels. Consequently, HKS/Mazzetti recommend mobile task lighting to allow for patient sleep/rest while providing lighting for staff.

FRESH START

Significant air movement and fresh air have proved a key component in knocking down the spread of COVID, opening up, if you will, the window for products once considered a luxury.

Continued Care While the country has generally succeeded in flattening the curve, unfortunately, that curve is still quite high, and in the absence of a vaccine, much concern and uncertainty abounds, particularly when the colder weather and flu season sets in this fall.

Hopefully, the hard work put in by the  industry to innovate new facility options for efficiently and effectively caring for patients will continue to serve the healthcare system well.

VERTICALLY FOLDING WALLS Construction Specialties (CS) has announced the launch of a new product brand, Vista Air Vertically Folding Walls, a flexible space solution that permits refreshing, open spaces while occupying a significantly smaller footprint than competitive systems such as sectional, counterbalance or “accordion” doors. The system’s low-profile design features Vista Air’s proprietary Rizon Lift System, which utilizes quietly meshing gears to replace the counterweights, tension springs, straps, hydraulic and pulleys traditionally found in flexible space management solutions. This innovative, low-profile lifting system helps streamline and reduce maintenance compared to competitive systems while also permitting clean, open design with no obtrusive bulkheads or steel tubes.

McCormick Place’s Rapid COVID-19 Alternate Care Facility Conversion

Fortunately, the convention center’s large open halls and regularly spaced in-floor utilities—power, data, water and drains—were ideal for setting up bays of patient spaces. Further, in the low-acuity areas in Hall A and Hall C, the large volume spaces allowed for ventilation to be directed upward and the creation of a negative pressure environment was achieved via the introduction of 100% outside air, while putting the air handling systems in maximum negative pressure mode.

At the same time, the existing units were not readily adaptable to reduce the volume of supply air to match the significantly reduced loading required for the Alternative Care Facility while also maintaining proper space humidity/

temperatures, explains Randy Ehert, ., technical director, electrical, Environmental Systems Design, Chicago.

Further, the heating and cooling coils on the existing air handling units were not properly sized to operate under these new conditions. © Walsh Construction

In record time, Stantec and Walsh Construction delivered 300 beds for low-acuity patients and moderate-acuity COVID-19 patients to relieve capacity in the City of Chicago’s hospital system. Directed by the U.S. Army Corps of Engineers, in association with The Metropolitan Pier and Exposition Authority, Environmental Systems Design was brought in for the mechanical, electrical, plumbing, medical cases and fire protection, and Thornton Tomasetti took care of the structural design.

“To overcome this situation, we calculated the maximum amount of outside air that could be brought into the space based on outside air conditions and developed a spreadsheet for the authorities to use so they could adjust the amount of outside air to each air handling unit, thus providing the maximum amount of air changes to the spaces per hour,” he explains.

For Hall B where the moderate-acuity patients were housed, additional  measures were needed. For each individual patient pod—750 in total—they were connected via a  filtered duct to a central duct system. “In a system suspended on a scaffolding system, ambient air from Hall B was drawn through the individual pods and into a localized  filter unit that drew the air into a centralized duct system,” explains Douglass King, principal, Stantec, Chicago.

“The  filtered exhaust air was then drawn by 10 large fans spread throughout the hall directionally upward and out of the

KEY CONVERSION PRODUCTS/ SYSTEMS LIST

hall through a return air duct system supported on the scaffolding surrounding the patient pods.”

An exceptional aspect of the , electrical, mechanical and medical gas system was the fact that Stantec and  designed the systems in 48 hours. Walsh then tapped into their network of medical subcontractors to quickly fabricate the systems.

“The biggest challenge was gearing up the / team response literally overnight,” reflects King. “We were fortunate that we had existing drawings of

McCormick place, but updating the  files into  for immediate use was a challenge.”

Another difficulty was setting up the nurse’s stations with the infloor utilities while still providing clear visibility down the corridor, reports Principal Health Sector Leader Susan Limbrunner, , . “Getting this right required some manipulation and more than one iteration.”

ADDED CAPACITY

As part of a nationwide effort to handle the surge in capacity caused by COVID19, suitable existing facilities have been converted to Alternate Care Facilities such as Chicago’s McCormick Place.

HVAC RENOVATION

“In order to isolate the COVID-19 designated floors, we had to seal off the central air supply and exhaust and create new systems to feed into the floors the team was working on.”

At St. Mary-Corwin Medical Center in Pueblo, Colo., the existing  system had to be renovated in order to reclaim two vacant floors for COVID-19 patients.

ASHRAE Weighs In In a “Pandemic COVID-19 and Airborne Transmission” bulletin, the experts at the American Society of Heating, Refrigerating and Air-Conditioning Engineers stated the following: Transmission of SARS-CoV-2 through the air is sufficiently likely that airborne exposure to the virus should be controlled. Changes to building operations, including the operation of HVAC systems, can reduce airborne exposures.

© Mortenson

Ventilation and filtration provided by HVAC systems can reduce the airborne concentration of SARSCoV-2 and thus the risk of transmission through the air. Unconditioned spaces can cause thermal stress to people that may be directly life threatening and that may also lower resistance to infection.

In general, the disabling of HVAC systems is not a recommended measure to reduce the transmission of the virus.

Colorado Delivers for COVID-19 To accommodate COVID-19 patients in Colorado, Mortenson was recently brought in to recommission space on abandoned floors at two Centura hospitals.

Providing more than 200 beds in less than a month’s time, the two design-build projects involved the renovation of two floors at St. Mary-Corwin Medical Center in Pueblo for non-acute patients and a threestory tower for acute and non-acute patients at St. Anthony’s North in Westminster.

“Both projects required a highly responsive, collaborative approach and the commitment of all stakeholders, and design and trade partners to successfully execute in a condensed time frame,” reports Keegan Snow, design phase manager, Mortenson, Denver.

To keep pace, the project teams worked to quickly disseminate information to enable efficient design making and worked around the clock with multiple crews, continuously commissioning mechanical equipment to ensure that the turnover date was met.

One particular challenge with the St. MaryCorwin Medical Center project was dealing with vertically-distributed air systems that served multiple floors. “In order to isolate the fourth and fifth floor—the COVID-19 designated floors—we had to seal off the central air supply and exhaust and create new systems to feed into the floors the team was

working on,” explains Mike Ross, Mortenson senior project manager.

Unique to new COVID-19 mandated working environments, all meetings were kept to under 10 people with 6-ft. distances. While working at the

hospital, all team members additionally complied with Centura’s policies, having their temperature taken when entering the building, wearing masks and limiting workers to two people per room in the 84,000-sq.-ft. space.

Beyond office buildings and schools, sustainably-minded architects are expanding net-zero designs into the realm of museums and cultural facilities, with a special focus on daylighting.

WELCOMING SITE

A north-facing clerestory and glazed windows welcome in daylighting at Scottsdale’s Museum of the West.

These facilities “have evolved from closed, vault-like buildings originally designed to protect their treasures into open, welcoming buildings that seek to play a more active role in the communities they serve,” states Scott Newman, , director, Cooper Robertson, New York.

“Museums and cultural buildings also have the unique ability to communicate sustainability principles to the public in ways that are much greater than other kinds of buildings because they are meant to be highly visited in prominent places,” notes Christiana Moss, , Studio Ma, Phoenix.

While museums do have unique lighting, humidity and energyintensity requirements, a number of creative design strategies can be leveraged to drive down loads. And because these buildings are built for longevity, ROIs can be longer.

Consequently, architects have a greater ability to significantly influence these designs.

SHADING

NBI Study Keys in on Optimizing Automated Shading Identifying automated shading as a key component in achieving net-zero retrofits for existing buildings, the California Energy Commission (CEC) has commissioned the New Buildings Institute to retrofit two Southern California offices with automated shading and upgraded advanced lighting in order to research a variety of factors. The specific automated shading system applied in the CEC study incorporates the following: View Section: A lower view section with a shade component that can be automatically raised and lowered in response to occupant or operator preferences or set to respond to sun patterns. The shade section has a large range of fabrics with various opacities to maintain screened views and outdoor connectivity.

Daylight Section: An upper daylight section above the view portion of the window contains concave louvers/blinds that can be automated to tilt in response to daily or seasonal sun angles and window orientation. The louvers throw daylight deeper into the space to provide natural light to occupants and to trigger daylight sensors that turn-off or dim the electric lighting.

PV-Powered Battery: A trickle-charge -powered battery provides the automation.

Wireless Control Option: The option for wireless controls reduces installation costs and eases retrofit applications.

So far, lab test results show 60% to 75% electric lighting savings and 20% to 35% cooling savings within a year for an existing building baseline. While the field study testing is just starting, the project goal is to exceed a 20% whole building energy reduction annually.

THE TRIPLE O

Newer product designs in automated shading cleverly address the “Triple O” interests of owners, operators and occupants, says Kathy Higgens, NBI research director.

Getting Started WHITNEY MUSEUM OF AMERICAN ART

When embarking upon a net-zero/near netzero museum project, Studio Ma first seeks to understand the climate, place and energy requirements. The next step is determining what kinds of lighting levels will be needed for the galleries, collection care areas and public spaces, and what portion of the building’s total energy load this will encompass. This information will then start to inform the daylighting design.

Furthermore, daylighting allows works to be shown in the full light spectrum in which they were conceived and

To test light-sensitivity and to evaluate illumination of those spaces, Studio Ma traditionally employs the modeling program Lightscape and more recently, have begun using Solemma’s DIVA, a highly optimized daylighting and energy modeling plugin for Rhino.

In fact, Gabe Guilliams, principal, Buro Happold, New York, reports that LED has reduced museum lighting

energy consumption by approximately 3W/ sq. ft. in gallery spaces for medium-sensitivity works—20-25fc target on walls—when compared to electric light.

As a result, museum lighting power densities can be achieved in the 1 to 1.5 W/sq. ft. range.

At the same time, he points out that LEDs increased use in museums has created a situation where electrical energy savings from daylight does not always offset the increases in mechanical energy to maintain stable temperature and humidity for daylit galleries in many climate zones.

For example, “new combinations of glass coatings can filter more than 99% of harmful UV radiation, while maintaining natural color rendition. These measures protect the artwork from damage, provide enough UV protection on their own, except from direct sun, and increase the building’s energy efficiency,” explains Newman.

Incorporating ample glazing and daylighting, Renzo Piano Building Workshop and Cooper Robertson designed a highly sustainable facility for New York City’s Whitney Museum of American Art.

OPTIMIZED DAYLIGHTING

A sawtooth roof line mockup helped the design team determine the sizing of the clerestory mixing changer for optimized daylighting.

Case in Point

Breaking away from typical museums where the only daylight is heavily filtered through skylights or clerestories, for New York City’s Whitney Museum of American Art, all four orientations are glazed with insulated glass units with warm-colored edge spacers and clear, low-iron glass with neutral coatings for minimal reflectivity and distortion.

Designed by Renzo Piano Building Workshop, in collaboration with Cooper Robertson, interior roller shades are strategically placed throughout the museum and roof-mounted sensors track the daylight as it moves around the building. The shades cover light coming in from doors and a 4-in. wide graduated ceramic frit prevents light from entering the galleries through the 1-in. gap between the shade and slender window mullion. In addition to protecting artwork, the level of solar control enables the gallery walls to be painted a neutral white without reflecting glare.

WHITNEY’S MUSE

A highly calibrated clerestory system delivers balanced daylighting to the museum’s eighth floor gallery.

“Museums and cultural buildings also have the unique ability to communicate sustainability principles to the public in ways that are much greater than other kinds of buildings because they are meant to be highly visited in prominent places.”

On top of the museum’s eighth floor, vertical skylights bring additional light into the gallery.

The clerestories feature a mixing chamber that is only 6 ft. to 7 ft. in depth, about half as deep than is typical. North-facing to receive diffuse light rather than direct light, this complex system was carefully modeled and calibrated through extensive daylighting studies.

For more details on how to optimize daylighting in museum spaces, and the Whitney Museum in particular, Cooper Robertson offers a white paper, “Daylighting: Flexibility and Conservation.”

In a similar vein, Studio Ma designed a clerestory for Phoenix Art Museum, and a north-facing clerestory at Scottsdale’s Museum of the West. The welldesigned system does a great job of illuminating the space below while using very little energy.

The project ultimately produced very low carbon emissions, and used minimal energy and water. “This bioclimatic solution points to new directions for cultural buildings, which are thought to always demand very high energy use intensities due to specialized lighting, security and rigorous air controls,” says Studio Ma founding principal, Christopher Alt.

OUTSIDE THE BOX

As an alternative to heavy light filtration via shades, which eliminates views out the windows, a freestanding wall can be constructed to separate the glass wall from the main volume of gallery space.

Skylights Brighten Manufacturing Facility

Maximizing daylight was the driving force for the building’s design. It has floor-to-ceiling windows, but they allow sunlight to permeate only so far into the building’s core. To truly bring natural light into the center of the manufacturing operations space, architects opened up whole sections of the roof with skylights.

Prioritizing daylighting for Burkert Fluid Control’s new 120,000-sq.-ft. North American headquarters in Huntersville, N.C., WHN Architects was in search of the right skylight system to meet the owner’s goals for outside views and open space. Although the facility is outfitted with floor-to-ceiling windows, they only allow sunlight to permeate so far into the building’s core. To truly bring natural light into the center of the manufacturing operations space, the architects opened up whole sections of the roof and installed VELUX Modular Skylights.

“What we did here was a bit outside the norm, especially in a manufacturing building, but I think we have created a healthy work environment,” states Paul Garafola, , ,  , partner,  Architects, Charlotte, N.C. “Thanks to the skylights, employees can have access to natural light throughout their day. It is a great space to work in.”

ENHANCED SKYLIGHT DESIGN Available in pyramid, single slope and ridge configurations, EXTECH introduces the SKYGARD 2500 series skylight system. In addition to typical daylighting benefits, the skylight is engineered with separate gutters to control condensation and leakage. Accepting glass up to 1.3125-in. thick, including monolithic or insulated glass units, optional glass coatings and custom silkscreen patterns can help diffuse the direct toplighting and control unwanted solar heat gain.

Trees, Let’s Hope, Sway in this Summer’s Breeze Tree-planting programs can lower energy consumption while sequestering excess carbon that inflames the climate crisis.

More “mature” readers will remember the Saturday morning “School House Rock” cartoons from the early ’70s. A favorite of mine was “Bill”— the story of a congressional bill trying to become a law. At one point in the cartoon explaining how laws become instituted, a boy asks “Bill” how it’s going. His sad reply, “I hope and I pray, but today I am still just a bill.” Well, an anxious bill awaiting such a fate, that I pray, passes, is The Residential Energy and Economic Savings or “TREES” Act. Sponsored by a bipartisan team, it incentivizes tree-planting programs that bring down energy

Urban trees remove over 710,000 tons of air pollution per year in the U.S., which has a major impact on fighting respiratory illnesses. consumption while sequestering excess carbon that exacerbates the climate crisis. It also pays special attention to environmental justice and equity concerns. Specifically, it would create a grant program to fund tree-planting throughout the United States, and give priority consideration to projects in underserved and disadvantaged communities. It would further recognize successful projects by naming an “Arbor City of America” annually, awarding extra funding to projects in that area. “As experts in blending the built and natural environments, landscape architects know, first-hand, the advantages of planting native, adaptive trees in projects and communities across the nation,” said Wendy Miller, , president of the American Society of Landscape Architects. ASLA worked closely with congressional staff in drafting its language.

As if we needed any more convincing, urban trees remove over 710,000 tons of air pollution per year in the U.S., which has a major impact on fighting respiratory illnesses like asthma. Trees also filter up to 80% of phosphorus out of stormwater. And tree canopy shade, along with evapotranspiration (the return of water vapor from trees and vegetation back to the atmosphere), can lower peak temperatures by 2°F to 9°F—a key tool in combating the heat island effect.

So, as summer comes full to bear, and greenery once again paints our landscapes, following are a few tree-inspired products to ensure your summer is made in the shade.

SHADY SITUATION When architects with SmithGroup’s Phoenix office began planning the entry for the new Eloy City Hall in Eloy, Ariz., Corten metal was their first choice for the shadeproviding canopy. When that material proved too costly, they turned to perforated 0.05-gauge aluminum PAC-CLAD 7.2 panels in an Aged Copper finish. The panels are installed on the underside of the canopy structure, with LEDs installed above. The lighting creates added visual interest once the sun goes down, and clearly identifies the entrance for residents.

The Heights Building Arlington, Va. The 180,000-sq.-ft. Heights Building merges two existing Arlington, Va. secondary schools on one small, urban site. The focal point of the school is its central staircase that cuts through the interior of the building connecting four tiered terraces, allowing students to circulate outside, forging a stronger bond between the neighborhood and the school.

“The density of the urban Arlington neighborhood became the inspiration for the school—we fanned the classrooms to allow each and every floor to be connected to the roof garden on the top of the classrooms below,” said architect Bjarke Ingels, founder and director of BIG. “The resultant cascading terraces are connected by a curving stair that weaves through all levels—inside as well as outside—making all students, from both programs and all ages, visually and physically connected to each other.”

The building’s material palette pays homage to the historical architecture of local Old Town Alexandria. On track to achieve LEED Gold, The Heights features a 400-seat auditorium, a gymnasium, library with each classroom bar defined by its own color, combining intuitive wayfinding.

Converging Architectural + Performance Goals

American Geophysical Union, Washington, D.C. Constructed in 1994, the original American Geophysical Union (AGU) headquarters building incorporated symbolic design elements representing the earth and space science studied by the organization’s 60,000+ members.

by John Mesenbrink, contributing writer

In approaching the 62,000-sq.-ft. building’s renovation, Hickok Cole sought to make both an architectural and environmental statement—situating the building firmly in the conversation around the future of net-zero energy development, while maintaining the integrity of the original design, which was of paramount importance to AGU, its neighbors,

68

2007APFXN.indd 68

and the local Historic Preservation Board.

In addition to modernizing the building and providing a new workplace and amenities for staff, AGU hoped to elevate awareness around the organization by incorporating a space for interactive exhibits. Open to the public, these exhibits showcase members’ work and illustrate

how science is applied to solve society’s most pressing issues today.

A recipient of the firstever DOEE Clean Energy DC Award in April 2019, AGU’s headquarters showcases progress in sustainable design and serves as a transparent resource for both the Earth and space science community and neighbors of the Washington, D.C.

region. “By becoming the first-ever net zero energy renovation of an existing building in the District, AGU hopes this move will catalyze the incorporation of similar approaches and designs into new and existing facilities throughout the city and beyond,” says Guil Almeida, , , Hickok Cole, and AGU Lead Designer.

From the start, AGU

intended this building to function as a living lab. Because the facility is open for daily tours, a major consideration for the project was ensuring public understanding of the building’s function and potential impact. To achieve this, the design team converted the below grade level into additional exhibit space, specifically dedicated to education around net-zero

energy. “From the outset, net-zero energy was of utmost importance to AGU. All other facets of the project were developed around this ambitious goal. The building is undergoing commissioning and is still on target to receive net-zero energy certification,” says Almeida.

In order to meet the ambitious goals for energy reduction, the team began with the envelope. Because the masonry portions of the original building envelope were in great condition, the team opted to leave it in place and augment the performance of ancillary elements such as the window system and interior insulation. Triple-glazed, thermally broken window units were installed with new attachment methods that eliminated the thermal bridge that resulted in the original attachment method of the windows. 8 in. of closed cell spray foam insulation were then added to the inside face of the  backup wall to create the tightest envelope possible within the constraints of the existing façade.

Sustainable Design ONSITE POWER/RENEWABLES

The new canopy mounted PV array is designed to provide more power annually than the building uses.

Connected to a DC power distribution system, the PV system components including the panels, inverter and rectifier all work together to deliver DC power throughout the building.

limited experience in designing for net-zero energy was by far the biggest challenge for the design team. “This concept in and of itself totally upended the design process, requiring all entities to be involved in every stage of development. And then, add to the fact that this project was a renovation, meant that the design team was faced with several

07 . 2020

2007APFXN.indd 69

preconditions to consider as well,” says Almeida.

Throughout the building, informative graphics point out significant operational features and explain how they contribute to net-zero energy while mechanical spaces are set behind glass to allow visitors a closer look.

Upon entry, an interactive dashboard in the

lobby presents an overview of energy consumption throughout the building. Eventually, the data collected will be uploaded to an open source website for AGU members and members of the scientific community to access and analyze.

An array of collaborative and welcoming environments allows AGU to better connect

and engage with its members and the public, while seamlessly facilitating the exchange of scientific findings related to Earth and space science through the use of technology and flexible design techniques.

Designing the most sustainable building possible requires a comprehensive understanding of the surrounding conditions. With the goal of powering the building entirely through on site-renewables, the small, urban footprint of the site was arguably the biggest constraint. Given that the project was also located in a Historic District, it was of utmost importance that the design be contextually sensitive. The resulting PV array, inspired by the cornices of nearby buildings projects 4-ft. beyond the property line, housing 720 panels.

Another sustainable strategy, largely dictated by the location, was the addition of a sewer heat exchange system. Geothermal piles would not be feasible due to the constraints provided by the structure of the existing building. Fortunately, buried 30-ft. below the main thoroughfare in front of the building was one of the district’s largest sewer mains. This enabled the team to utilize the sewer flow as a heat sink, much like a traditional geothermal system.

Daylighting By transforming their workplace from primarily private offices to an entirely open plan, coupled with the relatively shallow depths of the floorplate, daylight and views were now within the reach of every employee. To further this transformation, all new electrochromic glass eliminated the need for automated or manual sun shades, allowing glazing to dynamically address solar heat gain and glare to maximize occupant comfort and energy efficiency while maintaining outdoor views 100% of the time.

TINT ZONES

LightZone provides the end user with the ability to create up to three tint zones within a single pane of glass to let in exactly the right amount of light and block the sun as needed.

Water Management/Efficiency In addition to energy-efficiency measures, the AGU project implemented a number of water-efficiency measures as well. From low-flow plumbing fixtures from Kohler and American Standard to a rainwater capture and reuse system, potable water usage throughout the building has been reduced substantially.

The first of its kind in the United States, the building’s municipal sewer heat exchange system taps into an adjacent 1890s sewer line to maximize the efficiency of the building’s mechanical systems. The municipal sewer heat exchange system functions as a heat sink/source, operating by: diverting wastewater to a settling tank located just outside of the building; circulating the now debrisless water into a sewer heat exchanger located in the underground garage; and preheating or cooling separately piped in radiant fluid before it is recirculated throughout the building. It is a closed loop system; no sewage contamination will take place.

NET-ZERO DEVELOPMENT

The American Geophysical Union is a shining example of implementing sustainable design strategies from considering site orientation, rainwater harvesting and reuse, photovoltaic energy and a sewage heat exchange system.

Lighting Lighting is one of the largest end users of electricity in buildings, often consuming roughly one third of the entire building load. Pairing the use of highefficiency fixtures with lighting controls can reduce electrical demand and enhance occupant comfort and productivity. Not only do LEDs with lighting control reduce electrical consumption, but they also decrease the amount of heat emitted to a space, which, in turn, alleviates loads on HVAC cooling equipment. These are vital components for helping meet energy reduction goals by greatly reducing consumption in a building.

Perimeter offices and opaque shading systems were eliminated to allow increased access to natural light deep into the new floor plan.

Working Together

HVAC A number of unique and innovative systems were utilized to make AGU a net-zero building. In particular, radiant ceiling systems control temperature through radiation, which is a more efficient way to condition space than forced-air. Decoupling the building conditioning system from the dedicated outdoor air system (DOAS) reduces the overall energy needed to move air through the building since it’s now only needed for ventilation, not for space cooling.

While this wall looks like a standard green wall or vertical garden, the Hydroponic Phytoremediation wall actually functions as part of the building’s ventilation system. In conjunction with the DOAS, the Hydroponic Phytoremediation (HyPhy) wall filters and improves the quality of indoor air, while reducing the amount of outside air needed to support the building. The plants, their roots and the wall’s water filtration system scrub air of unwanted toxins and

72

ARCHITECTURAL PRODUCTS

2007APFXN.indd 72

volatile organic compounds before recirculating it throughout the building.

The DOAS provides a dedicated means for building ventilation. This system both conditions incoming air, and recovers heat from outgoing exhaust to raise the temperature of incoming air for space heating needs.

Combined, these systems help AGU achieve energy reduction and indoor air quality goals.

Collaboration was integral to the success of the project as the team came together at the early onset of design. As outlined by AGU, the collaboration process extended beyond the traditional players, like the general contractor and engineers, to include government agencies, like the DC Water and Sewer Authority. The project also included an extensive research and concept phase which required each project team to present a list of sustainable design strategies for consideration and potential application.

Furthermore, the design team worked closely with several community planning organizations to ensure the new headquarters design aligned with the neighborhood’s vision. AGU, which has been part of the Dupont Circle neighborhood for nearly 40 years, has strong support from the surrounding community, and the Dupont Circle Citizens Assn. Additionally, the project has received unanimous endorsements from Advisory Neighborhood Commission 2B and unanimous approvals from the Board of Zoning Adjustment and the Historic Preservation Review Board.

CHALLENGE: Convey the architect’s design inspiration within the hotel’s washrooms for Toronto’s high-end

Hotel X. “We envisioned an elegant European look that ensured as much privacy as it did design impact,” said Stephen B. Jacobs, FAIA, president and founder of Stephen B. Jacobs Group.

INFLUENCE: Hotel X Toronto was designed by Stephen B. Jacobs Group to embrace all the wonderful flavors

of the globe. Every detail was carefully selected to offer guests a modern, luxurious experience that encapsulates authentic hospitality and embraces the hotel’s historic and iconic location on 192 acres of city parkland in the heart of Toronto’s Exhibition Grounds. “It was imperative that every aspect of Hotel X contribute to providing guests with an unparalleled hospitality experience,” said Jacobs.

SOLUTION: Working together with ASI Group, the designers created a completely unique design that is

atypical in North America. Its sophisticated washrooms showcase luxury, with deep washroom partitions surrounded by towering Alpaco doors, panels and pilasters that extend from within inches above the floor, to nearly touching the ceiling. It meant working with ASI’s Alpaco plant in Belgium for large phenolic sheets, as well as flying an experienced installer to Toronto to guide local crews on the custom installation.

The washrooms complement the vibrant, upscale, tailored design of Hotel X, welcoming guests to an experience of delightfully sophisticated luxury. A marriage of simplicity and functionality creates a collection that has a perfect blend of luxury and ASI’s exclusive Ultimate Privacy at its heart. The system includes flush finish self-closing doors, that have a rebated finish for zero sightlines; an occupancy latch with an emergency unlatching device shows when partitions are in use; beveled edges that have an engineered polished black finish. The partitions are constructed of 13-mm thick Phenolic, which is antimicrobial, non-porous, water-resistant, impact and scratch resistant, and available in a range of standard and custom colors. Style and stability have not been sacrificed in this collection, with robust octagonal head rails adding to the seamless construction.

CHALLENGE: Developers of The Ten, at Clarendon, multifamily project

located just across the Potomac River from the U.S. Green Building Council headquarters, in Arlington, Va., needed to meet the latest LEED requirements, particularly to satisfy Arlington County’s Green Building Density Bonus Program, which established Incentives and financing for efficient buildings in Arlington, and would provide for expedited permitting for residential construction, as well as density bonuses for commercial development, and rebates for energyefficient lighting retrofits.

INFLUENCE: As a LEED Platinum certified apartment community, the Ten

at Clarendon is endowed with holistic qualities to foster modern community making—especially as seen through the lenses of sustainable design. With design principles aimed at leaving a minimal environmental impact, the Ten is an example that other developers and communities can adapt for positive change in the comfort, lifestyle, and resiliency in multifamily dwellings. Its features would include: • A green roof with access to a deck, raised-bed vegetable garden, lounge areas, and fitness center; • Electric-car charging stations; • Energy Star appliances, fixtures, lighting and programmable thermostats.

Wojan, the Ten at Clarendon incorporated horizontal sliders, and projected and fixed window units, which also required two separate high-performance finishes—bronze and charcoal.

Another unique component used was a 90-degree corner that allowed for cleaner and narrower sight lines. And per the client’s request, limiting devices were incorporated to minimize opening. “Wojan is proud to have been a part of this project because it demonstrated our versatile product line and ability to adapt to special project requirements,” says Pagano.

All Wojan products are AAMA rated for the most current performance standards, utilize dual-sealed insulated glass units, and most importantly, utilize Azo-Brader mechanical lock technology by Azon for the thermal barrier. These features collectively provide the end user with high-quality product and optimal thermal performance for the longevity of the materials.

The Ten was awarded the Best in Green (BIG) Multifamily Market Rate award by the National Assn. of Home Builders in 2019.

Winners were chosen based on their innovative use of green features, aesthetics, functionality, amenities and high-performance certifications.

SOLUTION: Not the least of these energy-efficient design elements would

be efficient window systems. Featuring thermal components from Azon, systems from Wojan Window and Door, were specified. According to Rick Pagano, vice president of sales at

Graham Architectural Products PROJECT:

Escondido Village Graduate Residences, Stanford University LOCATION:

Stanford, Calif.

CHALLENGE: Only 55% of Stanford University’s more than 9,000 graduate

SOLUTION: “We were able to morph the aesthetics of the 6700 with the

students are able to reside in on-campus housing. That said, constructing any new housing needed to minimize disruption to the campus, and would involve limitations in parking, delivery locations and access. In proceeding with plans for a set of four 10-story buildings which would become the Escondido Village Graduate Residences, adding 2,400 beds, the project had to address three critical concerns: time, energy efficiency and the state’s seismic requirements, which would fundamentally alter the design and construction process.

thermal performance of our GT6200, and in so doing create the basis for our whole GT6 platform,” said Bill Wilder, Graham’s director of technical sales.

All issues, however, weren’t resolved, as California’s seismic requirements added an additional wrinkle. Clark Pacific wanted to install the windows with strap anchors that would allow the windows to move in the event of an earthquake. But they also wanted something to hold the windows steady during the panels’ 2.5-hour journey from the company’s manufacturing facility. “Clark Pacific had a great engineering team, and they designed the strap anchors in conjunction with us,” says Wilder.

“That was really a collaborative effort to come up with a method of installation that allowed for both the required movement and the desired restraint during transport, while also delivering the aesthetic appearance that Stanford was looking for.”

After receiving client approvals shortly after Labor Day, 2017, Graham manufactured and delivered more than 6,200 windows—beginning in Dec. 2017 and continuing through early 2019. Clark Pacific, in turn, manufactured more than 14,000 panels. The project kept moving, with the various teams reaching consensus on one issue after another, from the look of the muntins, the glazing, and the type of spandrel glass to the paint finish, the colors, and the hardware finishes.

“We’d get feedback, address it, and turn it around,” said Mark Hiscock, national sales manager for Graham. “We talked to the architect, KSH. We talked to Clark Pacific, went back and forth with their design guys and KSH, and we designed a window that met their sightlines, their energy requirements, and their operational requirements. The whole things is amazing.”

INFLUENCE: To minimize on-campus construction activity, Stanford

partnered with Clark Pacific, a leading manufacturer of prefabricated building systems. University officials, also in the conception stage, discovered Graham Architectural Products’ 6700 Series window, which bears the appearance of an old steel factory sash. Marriage of forces wasn’t an issue, as Graham had experience supplying windows to precast panel manufacturers. That expertise became more important when Clark Pacific created its own window installation team for this project, as Escondido Village quickly became its second-largest project ever. That team would install the glazing into exterior precast panels in the factory, reducing construction activity on campus. The issue facing the project, however, was the 6700 did not meet California’s energy code. A custom product was required to blend two of Graham’s products together to bring the aesthetic of one to the thermal performance and manufacturability of the other.

Solar Control/Sun Shading

SUN PROTECTION

The Panovista Max sun protection screen on the sliding corner window— with a zip and without any intrusive profiles or cables in the corner—doesn’t have a supporting post.

Bordeaux Villa Adds to Outdoor Living New villa provides ultimate comfort for residents, both indoors and outdoors with sun protection.

CHALLENGE

In sunny Bordeaux, France, life moves effortlessly between indoor and outdoor spaces. However idyllic this sounds, it does pose one great risk: interiors can often get too hot, too soon.

INFLUENCE

Residents discovered after three months in their new home, given the orientation of the house, sun protection was absolutely essential. Even despite the fact the living room faces directly south, suitable sun protection keeps the interior cooler even on the hottest summer days. Thanks to the pergola in the garden, the homeowners can choose all year round whether to spend time indoors or outdoors, depending on which environment is most pleasant at any given time of day.

SOLUTION

“We installed pretty much every element of Renson’s sun protection range on this property,” says installer Frederic Lacoste of Renson ambassador Portaix Loisirs. “There’s a Panovista Max sun protection screen on the sliding corner window—with a zip and without any intrusive profiles or cables in the corner, which doesn’t have a supporting post—there are Loggia sliding panels on the windows and fixed Sunclips’ awnings above another window.” However, much of these solutions differ; they all make sure in the same effective manner that the sun never drives indoor temperatures in this well-insulated villa to

unbearable levels. They all block the sun rays before they even reach the glass.

The owners are delighted with the result. The main advantage is that they can open or close both screens and sliding panels as they wish, depending on the level of comfort they want to create or the amount of light they want to let in.

The same applies to the garden, which is a place where the owners spend a significant share of their time. To ensure they can keep enjoying their outdoor space even in a heat wave—and there have been several over the past few years—thanks to the integrated screens and tilting blades, the Camargue pergola can control shade and temperature even on the most sweltering days. Another advantage is that it offers a way to live comfortably outdoors even in spring and autumn. “On top of that,” the owners add, “the Loggia sliding panels not only provide the necessary shade but also allow us extra privacy for the hot tub.

“Right from the earliest design stages of their new home, the owners had a pool house in mind. Renson’s Camargue terrace cover with tilting blades was the perfect fit for how they imagined this space.

The builders were also immediately persuaded by the various sun protection solutions. To me, the fact that the owners felt comfortable in their new home straight away is the perfect proof that this was a successful project,” says architect Christine Bouchard.

Stone/Masonry

Napa Courthouse Reborn after Damage by Quake After a collaborative reconstruction, seismic retrofitting and historic restoration, the Napa County Courthouse, which was critically damaged by the South Napa earthquake in 2014, has been reborn.

CHALLENGE

Registering 6.0 on the moment magnitude scale, the South Napa earthquake was the strongest to hit the San Francisco Bay Area since the Loma Prieta earthquake postponed the 1989 World Series. In addition to damaging plaster finishes, HVAC and finish carpentry, the South Napa earthquake caused significant structural damage to the courthouse’s existing un-reinforced masonry walls.

CRITERIA

Although several construction methods were considered for the repair of the courthouse structure, concrete masonry unit (CMU) walls were rebuilt to replace the most heavily damaged masonry walls, while fabric-reinforced cementitious matrix () technology was selected instead of more traditional repointing and grout injection as the solution for the less damaged walls with their countless small cracks.

 systems are currently being introduced in the structural repair and rehabilitation industry as a new, effective strengthening technology offering reduced thickness, excellent durability, superior performance in high temperatures, and ease of installation versus traditional strengthening and repair methods SOLUTION

Pullman and ZFA used  technology from Simpson Strong-Tie, a brand new repair solution not used in California prior to the Napa County Courthouse restoration. “When Simpson Strong-Tie brought  to our attention, our confidence in them was at a high enough level that we felt comfortable using a product that had not been used before in California,” says ZFA Executive Principal Kevin Zucco. “We knew the product support was there, we knew the engineering background was there, and we knew we would get the approvals that we needed.”

To prepare the team for the first-ever application of  in California, mock-ups of the courthouse walls were built at a Simpson Strong-Tie research and development facility in nearby Stockton, Calif, to practice installing the  system. “From design support to field support, Simpson Strong-Tie was working with us hand in hand, and that made the process smoother and easier onsite,” says Pullman Project Manager Vivek Kumar.

Since  systems add less weight to the structure, they provide an excellent solution for strengthening concrete and masonry substrates, particularly in seismic retrofit applications.

500-ft.tall Hyatt Regency Seattle opened Dec. 2018, adding 1,260 rooms and 103,000 sq. ft. of meeting space.

Roof Hatches Integral to Seattle Hotel Design The $470 million, LEED Gold Hyatt Regency Seattle is the new crown jewel for the Emerald City.

SOLUTION

Four roof hatches manufactured by  provided an important component in the construction of the hotel. LMN Architects included two hatches that are 3-ft., 2-in. × 12 ft. and two more that are 3-ft., 2-in. × 14 ft. They provide rooftop access to mechanical equipment. “BILCO’s reputation as an industry leader and company’s ability to accommodate the sizes needed in a timely matter were almost assuredly important factors for LMN,” said Lisa Stevens of  Northwest, which procured the hatches for RC Building Specialties. The roof hatches are equipped with snow sensors and motorized operation. They also include safety railing systems.

The hatches were also equipped with motorized operation to facilitate opening and closing. They included modified curb liners and heating cables with snow sensors, which keep snow from accumulating on top of the hatch and automatically stop when the

storm passes. The curb features the Bil-Clip flashing system, an innovative method to quickly and easily secure single-ply roofing to the hatch. The hatches include compression spring operators for lift assistance and an automatic hold-open arm with grip handle release and are manufactured with corrosionresistant materials.  custom-built hatches include compression spring operators for lift assistance and an automatic hold-open arm with a grip handle release. They are also manufactured with corrosion-resistant materials. The curb features the Bil-Clip flashing system, an innovative method to quickly and easily secure single-ply roofing to the hatch.

The roof hatches were integral to the design of the hotel by the architectural team. “That’s what they specified, and we were able to install them without any difficulty,’’ said Chris Chesire, managing partner for RC Building Specialties, who worked on the project as a subcontractor for Sellen Construction.

The hatches required customization to be used on the roof of the hotel, which sits on an unusually shaped, narrow parcel in Seattle. The units were equipped with motorized operation to facilitate opening and closing in the city’s damp climate.

Oldcastle APG’s Echelon Masonry brand—InsulTech Insulated Concrete Masonry System (ICMS)

Sustainable Materials Integral to Atlanta’s Westside Park and Reservoir Megaproject With the city reconfiguring, the long-neglected Westside is undergoing a massive overhaul as its 400-ft. deep Bellwood Quarry is repurposed into Atlanta’s largest water reserve container.

CHALLENGE

The reservoir’s surrounding grounds are being developed into Westside Park, a 280-acre multi-use recreational space. This ambitious multi-phased effort addresses several issues associated with the city’s exploding population—water shortages and surpluses, an aging infrastructure and initiatives to balance development with environmentally responsible practices.

This 2.5-billion-gallon capacity gorge will soon hold a large portion of Atlanta’s potable water surplus, increasing reserves from three to five days to 30 to 90 days with city water supplies processed at the nearby Hemphill and Chattahoochee Water Treatment Plants.

INFLUENCE

The architect’s vision resulted in a magnificent blend of form and function. The grand structure features a native precast concrete outer shell, with a focal-point entranceway bookended by two soaring pilasters, which form a gateway for a striking arched-glass doorway. The complex will serve as the anchor for the evolving park aesthetic, and will soon be complemented by the adjacent Bellwood Reservoir, the next addition to this sweeping transformation.

SOLUTION

To combine sustainability and visual appeal, architects chose two products from Oldcastle APG’s Echelon Masonry brand—the InsulTech Insulated Concrete Masonry System (ICMS) complemented by Trenwyth Trendstone and Mesastone masonry units. Oldcastle APG’s Belgard Aqualine permeable interlocking concrete pavers (PICP) were used as part of the Hemphill site's stormwater management system.

The Atlanta-based PRAD group, a firm experienced in environmental watershed projects, has been a key player in several phases of this long-range venture.

Senior architect Tom Steele, the lead designer of the

07 . 2020

2007APSPS02.indd 83

quarry and treatment plant pump station structures, explained how InsulTech’s preassembled singlewythe structural masonry units fit the distinct specifications for the project.

By combining structural CMUs, EPS foam insulation, air/water barrier and exterior veneer into a single 12.25-in. unit, the InsulTech system has been shown to dramatically reduce labor time and costs as compared to traditional insulated cavity walls. Just as importantly, the system delivers true continuous insulation rated at R-16.2—far exceeding requirements of IECC 2015—without sacrificing the masonry aesthetic.

Steele discovered just how adaptable the InsulTech system was during installation at the Bellwood Quarry Pump Station, which involved executing a multipurpose design to house the pumps as well as electrical systems, conference and office spaces, a workshop and restrooms.

Although smaller in scale, The Hemphill Water Treatment Plant Pump Station required some complex coordination by masons. Since these buildings will blend into the Westside landscape, Trendstone and Mesastone architectural units—prefinished, integrally colored concrete blocks—were chosen as the finished outer faces for the InsulTech system. The units are manufactured with one or more faces ground to expose the variegated colors of the natural aggregates.

The 2.5-billion-gallon capacity gorge will hold a portion of Atlanta’s potable water surplus, increasing reserves from three to five days to 30 to 90 days.

PERMEABLE PAVERS

For the Hemphill access way, Oldcastle APG’s Belgard Aqualine permeable interlocking concrete pavers add the benefits of LEED points and drainage properties, as well as the ability to stand up to the heavy truck traffic.

Bellwood Quarry Atlanta, Ga. Design Team: PRAD Group PRODUCT SPECS:

With the Westside area predicted to undergo widespread development, architectural trends are somewhat difficult to predict. Therefore, the decision was made to design something as simple as possible for cost but with a little extra pizzazz for up-close viewing. Echelon’s comprehensive masonry offerings enabled Steele to strike the perfect balance.

Siding Completes Renovation at Boston-Area Condo The Residences at Atlantis Marina condominium complex replaces fiber cement with durable siding.

CHALLENGE

SOLUTION

The condominiums were built in 2007 and initially clad in fiber cement siding. Just 10 years later, its seaside locale, combined with a poor original installation, resulted in severe damage to the building’s exterior. According to PointsNorth Construction Management owner Nick Hall, this was the worst fiber cement siding failure he had seen in his career.

The construction company chose to rely on Chelsea Building Products, makers of Everlast siding, when faced with resurrecting an ocean-front condominium’s exterior cladding last summer. To remedy the situation, PointsNorth performed a complete exterior remodel, which included stripping the building back to its sheathing and installing a new adhered waterresistive barrier. Then, crews removed the previous fiber cement siding and trim, replacing it with Everlast siding and trim over 2-in. of rigid insulation.

“Typically, if there is going to be a failure with a fiber cement building envelope, you’ll know it within the first five years. Unfortunately, that was the case here and the system failure just got worse and worse,” added Hall.

INFLUENCE

PointsNorth had no choice but to completely replace the siding at The Residences at Atlantis Marina, a five-story, 44-unit condominium in Winthrop, Mass.

Just east of downtown Boston, the building offers residents outstanding views of the Atlantis Marina, the Boston skyline and the Belle Isle marsh below.

CRITERIA

Even after the fiber-cement manufacturer agreed to cover costs included under warranty, building owners said no to using the material a second time for the restoration instead wanted a product that met their expectations for visual appeal, longevity and durability.

a color-tinted acrylic capstock and embossed with an authentic cedar grain finish, producing durable, natural-looking siding.

The siding also features an industry-leading warranty that protects against excessive color change and ensures the product will not peel, flake, crack, rust, blister or corrode, regardless of color choice, for life.

“We had previously completed two smaller projects using Everlast siding, and my entire crew held the product in high regard,” said Hall. “From that initial experience, we saw no negatives in its performance, so it was an easy choice to use again on the Atlantis Marina project.”

Hall selected Everlast siding’s 6.875-in. reveal in Seaside Gray. The siding’s mineral composite construction is ideal for ocean-front locations where moisture and salty air are a constant strain on the exterior. The product’s appearance mimics that of real wood but with performance characteristics that far surpass wood, vinyl and fiber cement.

The siding consists of a thick and solid composite substrate called C CORE, which is made from a composition of inorganic minerals and polymer resins.

The substrate is then fused molecularly to

Hawaii Tackles Affordable Housing with HVAC Solution at Kapiolani Residence With affordable housing availability a problem in Hawaii, the state is incentivizing developers to tackle the issue.

CHALLENGE

SOLUTION

Hawaii’s cost of electricity for the residential sector is the highest in the nation—currently 2.5 times the national average—so it can be heavy burden on households that are already struggling.

Samkoo turned to Samsung, who recommended a design that featured a variety of residential and commercial HVAC products. Each residence, depending on the size of the unit, was equipped with either a Smart Whisper mini split system or Free Joint Multi (FJM) with Whisper wall-mount indoor units. These systems feature a digital inverter compressor, which operated at variable speeds to allow the compressor to run at precisely the speed needed to maintain the set temperature without turning the system on and off, adding efficiency and cost savings.

When developer Timothy Yi, President of Samkoo Pacific & Samkoo Hawaii, set out to build the 45-story Kapiolani Residence in Honolulu, Hawaii, he wanted to provide an affordable housing option with enhanced functionality and modern design. And part of its affordability had to be keeping utility costs low for residents as well.

CRITERIA

The housing project was built under the state’s 201H affordable housing law, which is administered by the Hawaii Housing Finance & Development Corp.

(HHFPC). Of the 484 units, 292 are offered as affordable housing units that are reserved for Hawaii residents who meet the household and income requirements set by the HHFPC. Due to the inclusion of lower income residents, Samkoo knew they wanted a heating and cooling solution that was cost effective for Kapiolani residents while keeping independent zone control for the units and common areas.

07 . 2020

2007APSPS02.indd 85

The wall-mount units feature a reusable filter that can be washed or vacuumed for additional savings.

And with the FJM system, tenants are able to control or turn off individual rooms/zones to avoid conditioning rooms that aren’t being used. Plus, the compact size and quiet operation of the Smart Whisper and FJM outdoor equipment allows them to be installed on lanais—or patios—without disrupting residents.

Similar to residential units, the building’s common areas have independent zone control and feature Samsung’s DVM S VRF system with ducted and cassette indoor units, including Samsung’s exclusive 360 Cassette. Its innovative circular design provides surround airflow evenly throughout the space with 0% airflow reduction and no cold drafts.

ADDED EFFICIENCY

A POST COVID-19 OFFICE

© HOK

In a post COVID-19 workplace, policy, planning and tangible changes—like strategic social distancing and more scrum environments—will influence design.

Stepping Up Leading the evolution of workplace interiors in a new COVID-19 world.

Recently elevated to the International Interior Design Assn. College of Fellows, HOK Director of Design, Interiors Bill Bouchey, , , is taking a leadership role in the firm’s approach to supporting clients and potential clients in adapting to an evolving COVID-19 workplace reality.

Described as a thoughtful partnering approach to help chart “a path forward,” HOK has termed this initiative APF. “APF promotes a human-centric tone, approach and attitude that puts health, safety, welfare and emotional well-being as the top priority in both the current built environment and the future built environment,” explains Bouchey.

These conversations are essentially centered around studies that examine current and evolving thinking regarding physical distancing, group gathering and assembly, and the potential impact. Regarding impact, the main issues are centered around policy, planning and short and long-term changes in the workplace environment.

“As a group of thought leaders, we meet weekly across the firm to monitor this activity and share knowledge so that we are prepared, aware and in constant communication about progress, events and lessons learned that benefit our approach,” he says.

In the arena of planning, HOK is currently assisting clients in mapping out future-proofing strategies, principles and best practices. According to

88

ARCHITECTURAL PRODUCTS

2007APLSD.indd 88

Bouchey, this is expressing itself in three areas: Smarter work definitions: Unlimited flexibility, mobility and agility are established for knowledge workers with an emphasis on care and choice.

Improved tools and procedures: As more people work from home, state-of-the-art robust technology and access to new programs that promote visibility and connection while accommodating future part-time work environments will be critical.

Workplace distancing: Everyone must help the world shift the definition of social distancing to remove any anti-human centric stigma. Physical or workplace distancing are more progressive terms.

The vision is to design spaces that provide comfort and bring us together.

As for the short term, Bouchey says, “We’ve considered that all workspaces could be defined as short-term scrum space environments—dedicated spaces where the team works—to promote flexibility and support just enough human contact to re-establish an emotional connection and a sense of place.”

In the long term, he says that the desire for human contact is a base human need and that there is great value in socializing, learning, training, ideating and innovating with teams and clients in-person.

Bill Bouchey, , , HOK Director of Design, Interiors, was recently elevated to the International Interior Design Association College of Fellows.

“The workplace will be restored as a destination for human contact. It will allow people the irreplaceable experience of being physically and emotionally connected to others while working together to solve problems and innovate.”

“The workplace will be restored as a destination for human contact. It will allow people the irreplaceable experience of being physically and emotionally connected to others while working together to solve problems and innovate.”

Reflecting on the pandemic is shaping architects’ roles, and he says that it has encouraged new levels of curiosity, compassion, empathy and imagination, and has reinforced the importance of designers putting themselves into the lives of numerous people to understand architects can design for all types of human experiences in the built environment.

“We are now a docent and ambassador of our client’s experience. Understanding how all end users function in a space is the foundation for creating enduring concepts and designs,” he concludes.
