The Murphy Arts District in El Dorado, Ark., started as a historic theater project. With the help of historic tax credits, it was expanded to include several existing buildings. Rendering courtesy DLR Group

HOW TO LEVERAGE HISTORIC TAX CREDITS More often than not, designing and renovating a building can be easier than actually funding the project. What many clients and developers donâ&#x20AC;&#x2122;t realize is that they may be able to finance a substantial portion of the total project cost through relatively under-theradar tax credits, one of which is a federal historic tax credit, writes DLR Groupâ&#x20AC;&#x2122;s Paul Westlake. In this blog post, Westlake offers step-by-step advice for leveraging historic tax credits on projects. BDCnetwork.com/Westlake

2018 OUTLOOK: ECONOMISTS POINT TO SLOWDOWN, AEC PROS SAY ‘NO WAY’

t’s early December, which means it is market forecast season for the AEC industry. Construction outlook reports from the American Institute of Architects, Associated Builders and Contractors, ConstructConnect, Dodge Data & Analytics, and FMI are beginning to roll in. And if the early prognostications are any indication, 2018 is shaping up to be a little less rosy for the nonresidential and multifamily construction markets. Dodge posits the U.S. construction industry has shifted into a “mature stage of expansion”: the 11-13% annual growth in construction starts we witnessed in 2012-15 will slow to 4% in 2017 and 3% in 2018. ConstructConnect is calling for 2-3% growth in nonresidential building starts between 2018 and 2021. FMI is a bit more bullish: 5% growth in nonresidential construction spending in 2018, then 4-5% in 2019-21. Despite the tepid outlook by construction economists—and numerous reports throughout 2017 that pointed to a looming growth slowdown for several major building sectors—optimism among AEC professionals has not waned. In fact, it has strengthened, according to a November 2017 survey of 356 architects, engineers, and contractors by BD+C. Six in 10 survey respondents predict that 2018 will be an “excellent” or “very good” business year for their firm. Barely half (50.3%) felt the same way this time last year, according to BD+C’s 2016 survey. Same for revenue forecasts: 62% predict their firm’s revenue will increase next year, and only 6.1% are calling for a drop in revenue. This is a markedly rosier outlook than last year’s, when 55.3% of respondents

forecasted revenue growth and 11.5% anticipated a drop. And while it has been an erratic and drama-filled first year for the Trump Administration—travel ban, Russian election interference probe, border wall financing fiasco, Paris Agreement withdrawal—the vast majority of AEC professionals are not overly concerned that the Trump-led White House will negatively impact their businesses.

DESPITE THE TEPID OUTLOOK BY CONSTRUCTION ECONOMISTS, OPTIMISM AMONG AEC PROFESSIONALS HAS NOT WANED. Just 16.6% of respondents cited “business impacts from the Presidential election” as a top-three concern heading into 2018. This sentiment is a somewhat dramatic turn from the post-election attitude, when nearly a third (31.7%) indicated that Trump was a major concern heading into 2017. So, what are the top AEC business concerns for 2018? Competition from other firms (54.3%), general economic conditions (43.5%), price increases in materials/ services (33.8%), and insufficient capital funding for projects (25.8%) top the list. Trump was at the bottom, along with avoiding benefit reductions and keeping staff motivated. When asked about their top business development strategies for the next 12-24 months, respondents most often cited: an increase in marketing efforts (47.4%), selective hires (46.3%), investment in technology (44.3%), and staff training (43.5%).

DESIGN ISN’T ENOUGH TO FOSTER COLLABORATION IN HEALTHCARE AND RESEARCH SPACES Collaboration has become an abiding design goal for many nonresidential building types, such as office workspaces and education institutions. But the medical field, with its hierarchical divisions and silo mentality among professionals, continues to resist a more collaborative workplace culture. Perkins Eastman set out to find out why. The firm used one of its own projects—the 95,000-sf NYU Winthrop Hospital Research and Academic Center, Mineola, N.Y.—as a test case a year after it opened in 2015. The firm’s post-occupancy evaluation report (perkinseastman.com/white_papers) focuses on the activities in a third-floor multi-use space in the facility that the firm designed specifically with employee interaction in mind. The white paper suggests

that even the most thoughtfully designed space won’t lead to meaningful change in a workspace if it isn’t supported by policies and attitudes that foster collaboration. That support is what Perkins Eastman found was missing at NYU Winthrop Research and Academic Center. Its third-floor space was seen as a microcosm of Perkins Eastman’s design intent. Its programmatic elements include a pantry with a small prep area and two vending machines, café dining space, and a break area with soft seating; a work room with a TV, tablet chairs, and writable magnetic wall; a research area with a large writable wall, movable ottomans, and hightop tables and writing table tops; and a conference room with a large executive meeting table and digital projection capabilities.

The percentage growth of total U.S. construction starts in 2018, according to Dodge Data & Analytics’ 2018 Construction Outlook. The report calls for a 3% climb overall, to $765 billion, up $19 billion from 2017. The single-family and multifamily housing sectors will see the biggest bump in starts and spending: 7% and 9% for single family, 11% and 8% for multifamily. Commercial building work will increase 2%, following a 3% gain in 2017. The sector

Educational facilities should see more substantial growth next year, lifted by the passage of recent school construction bond measures. Manufacturing plant construction will recede 1% in dollar terms, after surging 27% this year due to the start of several massive petrochemical projects. Next year should still see moderate growth for manufacturing plants in square footage terms. BDCnetwork.com/Dodge2018

HOW PROFESSIONAL BIAS COULD SABOTAGE INDUSTRY TRANSFORMATION In working with clients to create data strategies or custom software, we customarily engage in facilitating and prioritizing a multitude of viewpoints, debating skepticism, and building consensus. What we often discover from this exercise is that understanding one specific variable is central to navigating the complexities of stakeholder positions. That key variable: professional bias. Biases are natural tendencies in our thinking that may slant our decision making toward certain conclusions without critical evaluation. At best they can serve as an unconscious way to quickly process information, at worst they can lead to logical fallacies or forms of prejudice. Professional bias is a condition wherein you view the world through the particulars of your own job. Since our jobs (and the education that went

into them) make up a significant portion of our life experiences, it makes sense that our broader world view would be greatly influenced by the work we do. When confronted with a problem, our instinct is to go back to the methodologies we were trained to follow in order to evaluate possible solutions. Depending on your profession, you may look at an unused plot of land as a design problem, a safety hazard, a marketing opportunity, or a way to make money. Each of these viewpoints may be simultaneously correct, but one of them may need to be prioritized above all others. The challenge becomes getting buy-in from the other viewpoints. But what if professionals were to be confronted with an innovative concept that could potentially transform their enterprise, or even their entire industry? What happens when they are confronted with data

that contradicts their own professional upbringing? Or technology that may disrupt the need for their expertise? This is where professional bias can take the form of changeresistant thinking that can keep transformational or innovative ambitions at bay. In The Future of the Professions: How Technology Will Transform the Work of Human Experts, Richard Susskind and Daniel Susskind describe three kinds of bias that often emerge when professionals are confronted with new technology.

1. STATUS QUO BIAS refers to the tendency of professionals to prefer “continuing to do things as they are done today.” This bias may lead a professional to assert that their field is immune from change (what the Susskinds refer to as “immutable”). In the building industry, it is easy

‘WHEN CONFRONTED WITH A PROBLEM, OUR INSTINCT IS TO GO BACK TO THE METHODOLOGIES WE WERE TRAINED TO FOLLOW IN ORDER TO EVALUATE POSSIBLE SOLUTIONS. THAT COMES FROM PROFESSIONAL BIAS.' — NATHAN MILLER, PROVING GROUND

to see the status quo bias asserting itself in some kind of phrase like “This doesn’t address the reality of making a building today” or “This solution doesn’t account for [insert fringe design case here].” At best, biased professionals will adopt a technology purely as a means to enhance the status quo (using 3D BIM tools to produce 2D documents slightly faster, for example). At worst, they will dismiss a technology wholesale with very little critical evaluation. In an organization, this may result in uneven adoption of a technology—embraced by some, resisted by others. If you have ever overseen a construction firms’s transition from CAD to BIM, you have probably experienced some form of this type of status quo bias, and you are probably still confronting it today.

2. TECHNOLOGY MYOPIA refers to the inability to imagine future systems, platforms, and tools as being “radically more powerful than those of today.” It may also refer to the inability to recognize that the early adopters of a new technology may quickly become a mainstream skill set. This bias manifests

THE CO-WORKING EXPERIENCE NEEDS A HYBRID APPROACH The co-working market makes up 0.7% of the U.S. ofﬁce market. Since 2014, providers of shared ofﬁces have leased more than 3.7 million sf in leases of 20,000 sf and larger. Co-working spaces promote growth, innovation, and diversity. They offer a variety of work spaces, a community of creative people, and a sense of domesticity. But for co-working spaces to thrive, the services they provide must evolve with the needs of the users. I believe a hybridization of services is necessary to solidify the future of the business model and to bring in fresh clientele. Here are ways in which this could happen:

CO-MMUNITY SERVICE Co-working spaces pride themselves on creating a sense of community and a collaborative environment. However, this relationship should really extend to the local community. One way this could be done would be by introducing local youth to alternative creative disciplines. Many children have no idea what they want for their future. The co-working community can provide a network of inspiration and an introduction to a variety of professions. Who are we without our future

entrepreneurs, engineers, designers, and creative innovators anyway? This outreach could produce a network grounded in the community and create a revolving door of future users.

CO-RETAIL EXPERIENCE The co-working space of the future should implement retail within the space. The retail experience will attract users that would come in for coffee, a bite to eat, or to read the morning newspaper. If you are going to serve a small plate, why not serve the best bite of food, created by a coworking member trying to open a new restaurant? Whether it’s a T-shirt company or a product designer, the promotion of the products from within will reinforce entrepreneurship and ownership within the co-working community. Retail will supplement the revenue stream, bring in potential members, and enhance the space through a thoughtful user experience.

THE CO-TEL They hybridization of the hotel and co-working experience is essential to the evolution of co-working. We can take many lessons from brands like YOTEL, an innovative hotel experience based on technological

systems. The brand features electronic checkin systems, double beds that convert into sofas, and the YOBOT, a self-service robotic luggage concierge system. Yotel is an example of a company that was created for a very specific user experience within an already saturated market. The co-working space of the future will need areas for businesspeople to unwind or take a quick nap or shower before the next meeting. Whether for a short or extended stay, an intimate space to decompress from a day of travel or a centrally located space to break between creative sessions should be implemented into the brand. Artists and creative people keep odd hours of work, and creativity waits for no one. It is up to the co-working leaders to foresee these user needs and design accordingly. The co-working market is still relatively fresh. With two companies—Regus and WeWork—controlling 80% of the market, there is a lot of room for innovation. The hybridization of the co-working space with a retail experience, lounge scene, hotel-like feel, and local outreach will make for a dynamic, collaborative, community-based, social experience.

When we think of healthcare communities and children, we commonly picture them in a campus-wide daycare center that serves staff and their children or as patients in the pediatric department. But children are present in healthcare settings in other ways that are poorly understood, not often studied, and rarely designed for. Children often must accompany their parents to the adult’s diagnostic

accommodate children when their parents are being hospitalized? Several years ago, Jingfen Guo’s winning Interior Design Educators Council competition thesis (advised by Associate Professor Jihyun Song, MFA, Iowa State University) answered that seldomasked question with a design for a convertible patient room that can accommodate children when their parents are hospitalized in an inpatient setting.

‘CHILDREN ACCOMPANYING ADULTS IN THE HEALTHCARE SETTING CAN BE AN IMPEDIMENT TO BOTH THE PATIENT SEEKING CARE AND THE CAREGIVER’S ABILITY TO WORK.’ — DOUGLAS KING, Stantec

and treatment activities, whether in an inpatient or outpatient setting. We know very little about the impact of the presence of children on the ability for quality healthcare to occur. The truth is that children accompanying adults in the healthcare setting can be an impediment to both the patient seeking care and the caregiver’s ability to work. How can the design of healthcare settings

The following expands on this intriguing challenge for both inpatient and outpatient settings.

DESIGNING FOR BOTH PARENT AND CHILD What constitutes a cohesive patient room environment for a hospitalized mother and her children? What characteristics would define this space? How would this space be addressed when either

parent may be seeking medical care in an outpatient setting? We believe a childfriendly patient room must provide an interior environment that is therapeutic, controllable, and engageable for both the patient and their children. Here are five fundamental goals for achieving this: 1. Engaging the child. During their time at home or school, children tend to keep busy with some combination of work, play, or entertainment. It is important to design environments at the hospital where children can stay similarly engaged and active. In Guo’s design, a Family Zone provides an enlarged magnetic white board where the kids can draw. In the sensory corner, children or parents can smell, touch, and care for plant life. 2. A sense of control. At home, children have their own spaces and can decide where to sit and what to do. In Guo’s design, one of the main goals is to create a positive space where the family feels empowered by a sense of control. This includes the ability to set temperature and lighting and adjust the use of the space and furniture.

3. A safe environment. The child-friendly environment must keep children safe from infection and accidental collisions while promoting physical comfort. To do this, we should minimize sharp corners in furnishings and specify slip-resistant rubber flooring that attenuates sound. 4. A therapeutic environment. The primary function of the patient room is to provide a healing environment for the adult. A calm parent not only heals faster but helps put the children at ease. Natural materials, soothing colors, and adjustable access to natural light can promote healing and a feeling of well-being. Acoustic panels in inspiring hues and patterns can minimize noise to help shape that calm environment. 5. Multiple functions. Furniture should serve multiple functions to engage both parent and child. The family couch should incorporate outlets for device charging, a foldout table, and a task lamp for reading, writing, and drawing.

INDIANAPOLIS ZOO’S PAVILION IS MODELED AFTER A LUSH RAINFOREST The Bicentennial Pavilion and Promenade at the Indianapolis Zoo provides 40,000 sf of weatherprotected space for up to 1,000 seated guests. The open-air special events facility can host concerts, picnics, and private events. The zoo’s newest bird exhibit, Magnificent Macaws, is also located under the

pavilion and has a customdesigned stage and perch. The pavilion was inspired by a lush rainforest. It comprises eleven 35-foot-tall steel tree-like “pods” created mainly from natural materials. Each pod consists of 63 individual wood beams that range from 83 feet long and 19,000 pounds to three feet long and 25 pounds. Sunlight can filter through to ground level via translucent roofing materials. The “forest” of pods is held together

ASU COMPLEX DESIGNED FOR TRIPLE-NET-ZERO PERFORMANCE The new Interdisciplinary Science & Technology Building, or ISTB-7, on the Arizona State University campus is designed to achieve triple-net-zero performance, through reduced carbon, energy, water, and waste consumption.

Rainwater is collected 100% on site and percolates into an aquifer. As rainwater contacts the pavilion’s canopy, it is funneled into the pods, down rainscreens created from custom-designed weathered steel, to a sunken, plant-filled bed. From there,

the water travels through a water-quality unit into a 14-foot-deep water stone detention bed, designed to accommodate 100-year flood events. Each bed contains plants that can thrive in saturated environments, with water intake pipes that are raised above grade to encourage natural percolation through the soil.

The structure’s building materials absorb carbon and convert it to nutrients for durable materials and enriched soil. The atrium biome puriﬁes waste air. Wetlands landscape recycles water using natural, biobased methods. Rainwater is collected and sunshades help keep the interiors cool and comfortable. Sewage is treated and recycled via low-energy, biobased systems for use as graywater. Air currents, evapotranspiration, and photovoltaics are used to save and produce energy.

EUROPE TO GET ITS FIRST UNDERWATER RESTAURANT A new restaurant from Norwegian architecture ďŹ rm SnĂ¸hetta looks like it sprang from the pages of a concept art book for James Cameronâ&#x20AC;&#x2122;s 1989 film â&#x20AC;&#x153;The Abyss.â&#x20AC;? Under, which will become Europeâ&#x20AC;&#x2122;s first underwater restaurant, will be located at the southernmost point of the Norwegian coastline by the village of BĂĽly. It will also function as a marine research center. The structure will be sunk halfway into the sea. The exposed part will lie against the shoreline; the

underwater portion of the building will rest on the seabed five meters below the surface. Meter-thick concrete walls will protect against the pressure and shock of the rugged sea conditions. Large acrylic windows will offer views of the seabed as it changes through the seasons and under varying weather conditions. A path lined with informational plaques will lead guests to the restaurantâ&#x20AC;&#x2122;s entrance at the waterâ&#x20AC;&#x2122;s edge. From the entrance, guests will descend

through three levels: the wardrobe area, the champagne bar, and the restaurant. At the champagne bar level, a narrow, vertical acrylic window will showcase the transition between the shoreline and the ocean. Each level will employ a different color palette. The champagne bar is inspired

by the surrounding coastal zoneâ&#x20AC;&#x2122;s subdued colors of shells rocks and sand, while the dark blues and greens of the seabed, seaweed, and sea highlight the restaurant. Under will be able to accommodate 100 guests and will use muted lighting inside the restaurant and on the exterior seabed to help view the sea life through the main 4x11-meter panoramic acrylic window.

THE IS NOW Architects play a unique role in shaping our world: Each design decision inﬂuences how people perceive where they live, work and play. But steel, stone, brick and wood aren’t the only materials in an architect’s toolkit. Intangibles, such as light, air and temperature, also affect the way people feel in a space.

Electric lighting in buildings consumes 17 percent of all electricity generated in the United States, according to the U.S. Department of Energy. Research into worker comfort and productivity shows glare reduction and automated systems that optimize shade and natural light can contribute to improved worker productivity and reduced energy costs.

Shaping light through the use of shading devices should be central to the design process because without shade, life can quickly become unbearable. Think of the worker whose ofﬁce suffers from overheating and glare. Or the retailer whose customers don’t linger because the pedestrianoriented shopping district is too hot. Or the restauranteur who can’t ﬁll her patio seating because it’s totally exposed to the sun.

DRESS U P TH E SKYL IN E

Shade can boost commerce and improve worker productivity, not to mention it can protect people from health risks related to UV exposure. Shade design should be a priority whether the project is a streetscape, shopping area or high-rise ofﬁce building.

L I G HT C ON T R OL = C O S T S AV IN GS Building energy efficiency and worker productivity can be tied directly to effective shading systems in office structures. People need natural light for emotional and physical health, but researchers are finding that control of these daylighting features is a key element in the performance of buildings and the people who work in them.

Two architects recognized for innovative building shade designs in the Sunbrella Future of Shade competition conceived of fabric shade systems as a way to upgrade building performance, improve occupant comfort and give buildings a distinctive presence in a city’s skyline. ®

Puerto Rico-based architect and industrial designer Doel Fresse saw a need for automated shade in glass façade high-rise buildings, especially those located in the Caribbean. His conceptual design, “Helicon,” is inspired by the shape of heliconia flowers ubiquitous to the island nation. Helicon’s fabric panels create an intriguing geometric pattern on the building’s exterior. The panels can be adjusted to create interior shade, reduce glare or allow more light into the building when desired. Helicon, which is designed as a retrofit shade solution for existing glass façade buildings, improves the building’s overall energy performance by blocking light before it enters the building. The system can also be flattened to the building’s exterior to prevent damage during hurricanes or tropical storms.

Responsive Shading System by Arman Hadilou – United States

For architect Arman Hadilou, the intense summer heat in Austin, Texas, spurred him to conceptualize the “Responsive Shading System,” a kinetic façade of massive strips of fabric mounted on adjustable arms on the building’s exterior. The system responds to the elements, twisting the strips to create bigger or smaller openings depending on the angle of the sun and the time of year. In this way, Responsive Shading System balances building energy efﬁciency with the need to maintain views. The air gap between the building’s glass façade and the fabric façade allows for ventilation created by natural convection.

CON CL U SION Given rising global temperatures, creating energyefﬁcient buildings is more important than ever before. With shade at the center of the design process, architects can ensure energy efﬁciency is a priority, while also creating aesthetically pleasing buildings that promote occupant comfort.

15 NEWBRICK BRICK SYSTEM While traditional clay brick continues to be a workhorse material in new construction projects, it is rarely used as a structural building component. When compared to alternative nonstructural veneer options, such as precast concrete and thin-brick systems, clay brick can be excessive in terms of weight and installation time. Dryvit aims to resolve these concerns

with the introduction of NewBrick, a lightweight insulated brick product that is coated with a specially formulated finish to mimic the look and feel of traditional brick. The thin-brick material is installed much like bathroom or kitchen tile. Each unit is adhesively attached to almost any substrate— concrete, masonry, air/water resistive barrier, EIFS. The joints are then sealed with conventional mortar to replicate the appearance of handlaid brick construction. An engineered drainage plane removes incidental moisture. NewBrick is 12 times lighter than conventional four-inch face brick, weighing 2.45 lb/sf compared to 29 lb/sf. This weight savings means NewBrick is easier, safer, and faster to work with.

38 DEMAND DUO COMMERCIAL WATER HEATING SYSTEM

40 KONE JUMPLIFT CONSTRUCTION ELEVATOR

The Demand Duo commercial hybrid water heating system combines highly efficient heat exchanger technologies from Rinnai’s 199-Btu, Energy Star– certified C199 condensing commercial tankless water heaters, with a durable 119-gallon tank. The unit uses the building’s vertical vent penetrations, which eliminates the need to core additional holes in walls and roofs for external ventilation. The system produces more hot water in the first hour than traditional commercial systems.

The JumpLift system uses a mobile machine room that moves upward as the construction progresses to speed construction of tall towers. The self-climbing elevator operates during construction in a building’s permanent hoistway and allows transportation activities to take place in a dry, windproof shaft—and up to five times faster than with traditional external hoists. Once the building is completed, JumpLift is converted to a permanent elevator by installing the final machinery and finishing the material surfaces of the elevator car, landing doors, and signalization.

n February 24, 2017, The New York Times published an article regarding the eventual decommissioning of the Indian Point Nuclear Power Plant, just north of New York City, which the governor intends to close by 2021. A report on the implications of the plant shutdown found that the need to find new sources of energy could be mitigated if New York followed the lead of Massachusetts and Rhode Island in providing incentives to drive down energy consumption, particularly through improved efficiency in building systems. Energy codes mandating more efficient use of buildings—and, by extension, of building enclosures—are already being adopted by many states as a logical step in the reduction of energy consumption.

the impetus to improve building energy performance is manifest in the latest and most far-reaching model energy code from the International Code Council, the 2015 International Energy Conservation Code (IECC). Compared with energy standards of just a few years earlier, the 2015 IECC sets a high benchmark for energy performance. In 2010, the required insulative value for a new roof on an existing commercial building was R-20, per the IECC. Today, it’s R-30, a 50% increase. Replacement fixed windows in 2010 needed to perform at R-1.82. Now, that number is R-2.38, 30% greater. This trend toward increasingly stringent energy performance standards is likely to continue. Several states and municipalities, including New York, New Jersey, and Maryland, were early adopters of the 2015 IECC. Others have already passed legislation to roll out the new, more demanding energy standards over the coming months. For design professionals, designing and detailing building enclosures to meet these strict performance benchmarks demands knowledge not only of building envelope systems, but also of the requirements and objectives of the energy code, the fundamentals of thermodynamics and energy transfer, and highefficiency enclosure detailing. For property owners and facility managers, understanding the code requirements for energy-efficient design, the science behind those standards, and the process involved in achieving energy performance goals is critical to an informed and judicious approach to planning construction that meets stringent energy mandates. When and why to exceed the requirements of the code, and how to balance energy-use goals with practical considerations such as constructability, performance limitations, product availability, logistics, and cost, are further considerations. In some cases, it makes sense to go beyond the published standards and achieve forward-thinking energy performance that looks ahead to energy-efficiency trends. In other situations, the net energy reduction for a given upgrade may not be sufficient to justify the costs. Primarily, these considerations pertain to new construction, but some of the cost-benefit analysis could just as well apply to retrofit decisions for existing buildings.

UNDERSTANDING THE CURRENT ENERGY CONSERVATION CODE First issued in 2000, the IECC is a model code, which means that it is not, in itself, a regulation or law, but rather a set of directives that may be adopted by state or local jurisdictions, either as is

The use will likely be current edition, published in 2015, mandated by code. incorporates ANSI/ASHRAE/IES Standard 90.1-2013 – Energy Standard for Buildings Except Low-Rise Residential Buildings (ASHRAE 90.1). A reference standard, ASHRAE 90.1 provides minimum requirements for energy-efficient building design and establishes criteria by which to determine compliance. There are three basic steps to meeting energy code requirements. First, identify which version of the IECC applies to the project. Second, to establish performance criteria, determine the correct building climate zone. Finally, choose the correct path to energy code compliance dictated by the characteristics and composition of the building dictate. STEP 1: Know Your Code The 2015 IECC is the newest version of the code and therefore a logical reference point for this discussion. However, it is important to know which version of the code is in effect for the jurisdiction in which a building is located. If there is no legal reason to comply with a newer, more stringent version of the IECC, then decisions about the energy performance of a building

STEP 2: Know Your Climate Zone To design an energy-efficient building enclosure, it is essential to identify the type of climate in which the building is located. The basic distinction is between heating climates and cooling climates. ASHRAE 90.1 uses the concept of heating degree days (HDD) and cooling degree days (CDD) to characterize these two climate types. Degree days are calculated as the difference between the mean temperature and a given base temperature, in this case 65°F for HDD and 50°F for CDD. Heating days have an average temperature below 65°F, while cooling days are warmer than 50°F. HDD and CDD are aggregated over the course of a year, to specify the nominal heating or cooling load and to estimate energy consumption. If annual HDD exceeds CDD, the building is in a heating climate, or one that requires the use of heat more often than air conditioning. If the opposite is true, then the building is in a cooling climate. While heating and cooling are the chief climate identifiers, there are many distinctions beyond these two broad categories. For the continental United States, ASHRAE 90.1 identifies no fewer than seven climate zones. From a practical design standpoint, though, there are four main climate types to consider: Q Moist heating climate Q Dry heating climate Q Moist cooling climate Q Dry cooling climate For each of these climate types, the IECC and ASHRAE 90.1 provide prescriptive requirements for energy efficiency of the building envelope. Before applying these values, however, you must first quantify certain key characteristics of the enclosure design to establish whether the prescriptive path is appropriate for the building. STEP 3: Know Your Building Whether the prescriptive values set by ASHRAE and the IECC can be used to design an energy-efficient, code-compliant building envelope depends primarily on the percentage of glass in the façade. Prescriptive Path The 2015 IECC states that, to follow the simpler, prescriptive path to energy code compliance, vertical fenestration area must not exceed 30% of the

above-grade wall area. That figure includes windows, window walls, and glass doors, but not opaque doors and spandrel panels. For most climate zones, the proportion of glazing may be increased to 40% if code-compliant, daylight-responsive shade controls are incorporated into the design. When considering the curtain wall buildings that dominated new construction in the second half of the 20th century, it may seem excessively restrictive to limit window area so severely. However, most of the energy loss across a building enclosure is through the fenestration. The code recognizes that glazed assemblies are inefficient when compared with the opaque portions of the building envelope. Furthermore, additional glazing is often unnecessary to achieve the desired indoor environment. As a result, the IECC and ASHRAE 90.1 (and, by extension, the jurisdictions that adopt them) are stipulating a reduction in the proportion of fenestration in building façades as a reliable way to improve energy efficiency. Quantifying Glazing Performance Let’s look briefly at the science behind these claims. The energy efficiency of building materials is broadly defined by their ability to conduct or resist energy transfer. For fenestration, energy performance is defined in two ways: Q Solar heat gain coefﬁcient (SHGC), a measure of how much of the sun’s heat transmits through the windows and into the building interior. Q Thermal transmittance (U-factor), a material or assembly’s propensity to conduct energy. U-factor is the inverse of R-value, a measure of resistance to energy transfer. Within a building, most heat accumulation attributable to radiation is the result of solar heat gain through the glazing. However, reducing the SHGC of windows is a tradeoff, for as SHGC diminishes so too does visible light transmission (VLT), a measure of glass transparency. As with heat gain, most energy loss at the building enclosure also takes place through glazed assemblies. This tendency is reflected in the maximum allowable U-factor established by the IECC, which is higher for fixed fenestration than for mass walls by a

assembly become about balancing practical concerns with performance goals, rather than about meeting immutable efficiency requirements.

High-efﬁciency details, such as warm spacers at window assemblies, prevent heat loss/gain by providing a thermal break at conductive materials, like metal-to-metal connections.

factor of three. In the design and construction industry, it is now generally accepted that fully glazed walls are not necessary to achieve optimal daylighting or visibility. According to the U.S. Green Building Council’s Leadership in Energy and Environmental Design Reference Guide for Building Design and Construction, only window areas from two feet, six inches to seven feet, six inches above the floor are considered “vision glazing.” Windows below this “do not contribute to the daylighting of interior spaces,” according to the USGBC. Despite the established advantages of limiting glazing area, there are reasons designers or building owners might incorporate a greater proportion of glass than the 30% cutoff. What then?

understand what an “energy-efficient” building envelope really entails, it’s useful to consider what these values represent in terms of performance. The most straightforward path to energy code compliance is the R-value method, whereby an exterior wall achieves conformance if insulation of a certain R-value is provided (as per IECC Table C402.1.3). Although adding a thick layer of insulation may seem the simplest way to meet energy-efficiency standards, the complexity of modern building envelope systems may render this method impractical, or even impossible. A second path to compliance is the whole-assembly U-factor method. In this approach, the thermal efficiency of the entire wall assembly is calculated to determine the overall U-factor, which is then compared to the maximum values set by the code (per IECC Table C402.1.4). In practice, the wholeassembly method is likely the more complicated path to compliance, as the thermal values used for the various wall components are strictly dictated by ASHRAE 90.1. When modeling an enclosure to demonstrate conformance, other material characteristics, such as heat capacity, must be taken into consideration.

COMBATING AIR AND VAPOR MIGRATION Building Envelope Tradeoff Option Rather than plug in the energy-efficiency values set by the IECC in the prescriptive path to compliance, the project team would need to model the building to demonstrate that it will perform as efficiently as one with the requisite percentage of glass. Typically, such modeling follows the IECC methodology for the Building Envelope Tradeoff Option, which enables designers to make up for inefficiencies in certain elements of the building enclosure (in this case, a preponderance of glass) through superior performance of other assemblies, such as opaque walls, roofing, or lighting. However, depending on how far the proportion of vertical fenestration exceeds the prescribed maximum, compensatory efficiencies in other building systems may become cost-prohibitive or not in keeping with design requirements.

A code-compliant, properly designed, energy-efficient building enclosure relies not only on adequate insulative performance, but also on comprehensive control of the flow of air and moisture. The American Society of Heating, Refrigerating and Air-Conditioning Engineers’ ASHRAE Handbook – Fundamentals warns that “improving a building envelope’s energy performance may cause moisture-related problems,” and advises that “only a sophisticated moisture control strategy can ensure hygienic conditions and adequate durability for modern, energy-efficient building assemblies.” Since heat, air, and moisture transfer are interrelated, the building envelope design must not treat each separately, but, rather, should effectively integrate comprehensive management of hygrothermal forces (i.e., heat and humidity). Evaporation and removal of water are of paramount concern.

UNDERSTANDING THERMAL EFFICIENCY

Designing Comprehensive Air Barrier Systems The primary purpose of an air barrier system is to reduce the flow of air between the building interior and exterior. However, air barriers may also restrict the migration of water vapor. Since excess moisture can lead to premature deterioration of building components, the design should consider the impact of air barrier assemblies on water retention.

To quantify a material’s ability to resist the transfer of energy—to act as an insulator, rather than a conductor—the design and construction industry uses R-value, the reciprocal of U-factor (the tendency to transfer energy). In most cases, the IECC and ASHRAE 90.1 provide standard R-value and U-factor numbers of materials and assemblies, but to

64 | BUILDING DESIGN+CONSTRUCTION |

Design and installation of appropriate and comprehensive air barriers is mandated by the IECC (Section C402.5), which stipulates that air barriers must be continuous “throughout the building thermal envelope.” To achieve compliance, care should be taken to provide continuity of the air barrier across changes in the building envelope. Large-format detail drawings are especially critical to illustrate air barrier installation at transitions in materials and assemblies, changes in plane, and intersections with fenestration and roof areas. Particularly at seams and transitions, the air barrier must be designed and installed to resist forces that tend to deteriorate the assembly, such as expansion/contraction and differential movement. Implementing Vapor Control IECC requirements for vapor control are less stringent than for air barriers. Without a comprehensive air barrier system to restrict air flow, vapor control strategies are largely ineffective. The extent to which vapor management is needed, and the appropriate design of such a system, is dictated by: Q Climate Q Building use and construction Q Potential sources of moisture beyond interior water vapor Design consideration should be given not only to keeping water vapor out, but also to alFor some buildings, lowing moisture to escape when it may be less envithe building enclosure gets wet. ronmentally costly to leave windows as To permit the exterior envelope is than it would be to dry, a semipermeable vapor reto replace them. tarder may be specified. In other cases, a system with very low permeance may be appropriate, so the architect or engineer should evaluate the building, climate, and situation and design accordingly. When vapor retarders are required, their placement relative to the insulation layer of the wall assembly is extremely important. Typically installed on the warm side of the insulation, “the retarder should be at or near the surface exposed to higher water vapor pressure and higher temperature,” according to the ASHRAE Handbook – Fundamentals. ASHRAE 160 – Criteria for Moisture Control Design Analysis in Buildings is a

ENERGY-EFFICIENCY CONSIDERATIONS FOR EXISTING BUILDINGS Applying new energy requirements to existing buildings can be a difficult undertaking. How do we assess the current thermal performance of the exterior enclosure of a building constructed in the 1940s? If we’re replacing 10 sf of a façade, should we install an air barrier as part of the replacement system, even if the rest of the building was constructed without one? Chapter 5 of the 2015 International Energy Conservation Code addresses the issue of energy performance when working on existing buildings. The IECC tries to strike a balance between the need to achieve a high level of performance and the financial and practical limitations inherent to upgrading existing assemblies. Section C501.2 establishes the intent, stating, “…this code shall not be used to require the removal, alteration, or abandonment of, nor prevent the continued use and maintenance of, an existing building or building system lawfully in existence at the time of adoption of this code.” The IECC expands on this concept by exempting historic buildings from conformance with the energy code when “compliance … would threaten, degrade, or destroy the historic form, fabric, or function of the building.” There are good reasons for this. From a practical perspec-

tive, mandating that entire building systems or assemblies be brought up to current code standards, when only a portion of that system is affected by a scope of work, could cause financial hardship and a huge disruption to the building’s activities. There is also a case to be made for the impact such farreaching alterations would have on the environment. Existing buildings have embodied energy, a measure of the resources consumed to originally manufacture or extract materials and construct, say, a building façade. That energy can then be compared to the additional energy required to remove that façade and replace it with a new one. Often, preserving the embodied energy of the built environment by only addressing the portion of an assembly that requires repair has a greater benefit to the environment than the increased energy efficiency realized by complete replacement. The IECC discusses in some detail whether alterations require compliance with the code when portions of existing systems or assemblies are modified or replaced. New windows, for instance, need to comply with the energy code, while storm windows installed over existing fenestration do not. The code also makes a distinction between “alterations” and “repairs,” exempting the latter from compliance. Additions to existing buildings are afforded no such latitude and are regarded as new construction by the IECC, requiring full compliance with the code.

recognized standard for evaluating the need for and placement of vapor retarders. Dealing with Condensation When humid air contacts a cool surface, water vapor changes from gas to liquid, collecting in droplets through the process of condensation. To prevent water damage, insulation should be thick enough to maintain the surface above the dew point, the temperature at which condensation can occur. Even without reaching the dew point, persistently high relative humidity can still create problems, notably mold growth. Under the right conditions, though, a limited amount of interstitial condensation can be tolerated, provided there is ample opportunity for the assembly to dry. Analysis of moisture migration is complicated, and an accurate evaluation requires consideration of numerous variables within the building system.

Unfortunately, the danger of overreliance on simplified models is not limited to condensation analysis. Thermal efficiency calculations, too, tend to oversimplify the behavior of the system. Analyses used to determine energy code compliance for opaque wall assemblies, including the R-value method and wholeassembly U-factor method, may overrate insulating value by as much as 80%. What these models fail to consider, primarily, is thermal bridging, whereby highly conductive materials pass through insulation layers and transmit heat across the wall assembly. Generally, thermal bridges can be grouped into two categories, based on their geometry: Q Linear transmittances, where heat flows across the exterior wall along a two-dimensional length, such as at floor slab edges, parapets, window and door heads/sills/jambs, and the base of walls Q Point transmittances, which transfer heat at a single point of intersection between the wall and another object, such as at beam penetrations. How significant is the impact of thermal bridging on energy performance? For a simple opaque exterior wall, the clear field, or basic wall assembly without penetrations, might have an R-value that falls well within the prescriptive requirements for the climate zone and type of construction. However, factoring in linear transmittances could reduce the total R-value by more than 50%. This reduction in performance illustrates the importance of eliminating linear and point transmittances in building enclosure design as much as possible. Highefficiency detailing considers these potential sources

of energy loss and incorporates thermal breaks that insulate against heat transfer at windows, doors, floor slabs, roof edges, and the bases of walls. The latest version of ASHRAE 90.1 now requires that linear transmittances must be accounted for in energy-performance calculations. Updated requirements for the Building Envelope Tradeoff Option (ASHRAE 90.1, Normative Appendix C) stipulate that uninsulated assemblies, such as projecting balconies, roof parapets, and floor slab edges, must be separately modeled to achieve compliance.

WHEN HIGH-EFFICIENCY ENCLOSURES GO WRONG (AND WHAT TO DO NEXT) If high-efficiency enclosures are designed incorrectly, they can actually have an adverse impact on performance. Common problems include: Q Condensation Q Drafts and cold spots Q Mold growth Q Premature deterioration of building materials and assemblies Q Scant energy savings and increased costs Ironically, even when they are designed correctly, high-efficiency building enclosures can still succumb to problems. Notably, the comprehensive insulating of the building envelope has led to increased problems with snow and ice build-up on the exterior of buildings. To compensate for the thermally insulated enclosureâ&#x20AC;&#x2122;s tendency toward moisture accumulation in the colder months, the design professional can include provisions to optimize weather integrity while maintaining peak energy performance.

THE FUTURE OF ENERGY-EFFICIENT BUILDING ENVELOPES As states continue to seek opportunities to reduce energy consumption, more attention will be paid to building envelope details that reduce inefficiencies. Incorporation of design details that minimize energy loss can result in improved indoor comfort, as well as cost savings through smaller heating, ventilation, and airconditioning (HVAC) packages and reduced utility bills. To balance performance and practical considerations, an energy-efficient enclosure should apply principles of energy transfer, heat loss, and moisture migration. By considering how energy code requirements are derived and why certain design factors impact performance, building owners, managers, and design professionals are better positioned to develop building envelope solutions that achieve real-world efficiency demands without compromising aesthetics, comfort, or longevity. +

| GREAT SOLUTIONS | By David Malone, Associate Editor

THE ALPHABET OF LIGHT: A TO Z FROM BIG THROUGH THE USE OF LED-ILLUMINATED TUBES in opaque injection-molded acrylic, Bjarke Ingels Group has created a new font known as the Alphabet of Light, which can be used to design lighting in spaces with letters, numbers, or graphic signs. Custom light fixtures are created using simple base modules with specific geometric proportions that can be combined to create linear or curved structures of light. The resulting numbers and letters can be hung on the wall and combined with linear and circular shapes suspended from the ceiling. Alphabet of Light includes 29 uppercase letters, 29 lowercase letters, and 10 numbers. The uppercase letters are between 95 cm and 116 cm tall and 65 cm and 95 cm wide (with the exception of “I”). Lowercase letters are 65-95 cm tall, and 5-95 cm wide. The fixtures mount 9 cm from the wall and have a maximum mounting distance of 15 feet from the remote driver.

ARTEMIDE/BIG

Bjarke Ingels Group creates words and numbers using light. Alphabet of Light Suspension offers two choices: Alphabet of Light Linear, available in 120 cm, 180 cm, and 240 cm lengths; and Alphabet of Light Circular, available in diameters of 90 cm (six modules assembled) and 155 cm (eight modules). Each fixture uses brushed aluminum support pins and offers continuous 360-degree light emission from a patent-pending mixing chamber. Power consumption varies from 8W for an “I” to 32W for an “Æ.” Life expectancy: 50,000 hours. Bjarke Ingels Group designed the Alphabet of Light collection in collaboration with Artemide (tinyurl.com/ AlphaLightBIG).

Artemide’s new Alphabet of Light ﬁxture collection, designed by Bjarke Ingels Group, uses a framework of simple geometries that allows designers to create a variety of shapes and graphics, including numbers and letters.
