editor’s NOTEBOOK
New Green Stuff For Your Eyes, Ears It’s October, and that means it’s time for our annual Green Construction issue. This is one of my favorite issues of the year because we devote so much of it to sustainable construction. It also signals that Greenbuild lies ahead, and that’s always a fun show to attend. enovate In addition to several articles about sustainable design/ construction, we are introducing a new department called Renovate!. Renovation activity is quite high these days, and I don’t feel that it’s simply because there isn’t new construction. There are a lot of existing structures, vacant or occupied, that can be great commercial spaces if a little sustainable construction is applied. We want to tell you more about what people are doing, so keep an eye on the Renovate! page in each issue and watch for regular features about sustainable renovation next year. In addition to the new department, we have two new Commercial Conversation podcasts (www. commercialconversation.com) that coincide with this issue. I’m enjoying recording these podcasts and learning a lot. If you haven’t listened, give them a try. The length is between 30 and 40 minutes, so they won’t consume a big chunk of your day. The first podcast is with Gale Tedhams, director of product and supply chain sustainability at Owens Corning, Columbus, OH, and author of this month’s The Green Angle column (p. 6). In the column she talks about the BioPreferred program. In the podcast we discuss BioPreferred, but spend a majority of our time talking about trends Gail is seeing in the sustainableconstruction market, particularly the role of LEED and IgCC (Int’l Green Construction Code). It’s an interesting and revealing discussion from someone who spends her days evaluating how products help and hurt efforts to design and construct green facilities. The second podcast is with architect Jay Brotman, a partner at Svigals & Partners, New Haven, CT, and a leading expert in laboratory design. It was great fun learning from Jay about trends in laboratory design, the role of sustainability, and the challenges of retrofit projects. Even if you don’t design laboratories, there is much to learn from Jay. Please set aside some time to listen to these and our other podcasts. I’m rapidly lining up people for future podcasts, so sign up at www. commercialconversation.com to receive e-mail notification when new recordings are posted. I hope you find this issue and the podcasts informative and useful in your job. If you’re attending Greenbuild, stop at our booth and say hi. We always have Tootsie Rolls for nourishment.

The Green Angle
The Preference Is For BioPreferred Gale Tedhams, Owens Corning
R
esponsible building initiatives are a permanent fixture in the construction industry, influencing not only a building’s overall design, but how it’s constructed and the materials it uses. However, “responsible building” can have multiple meanings. Sustainable construction ensures that an environmentally responsible approach is used throughout the development process, from building design to material selection and operation management. Of course, responsible building also addresses safety throughout the construction process, in how the building is used, and in terms of accessibility, including following the Americans with Disabilities Act. Site selection and development to enhance the surrounding community and use of responsible construction practices, such as recycling construction waste, may also factor into the project. Among the newest approaches to responsible building is the use of materials that encourage domestic economic growth by reducing U.S. dependency on foreign materials One such program is BioPreferred, which is managed by the U.S. Department of Agriculture (USDA), Washington. Initiated by the Farm Security and Rural Investment Act of 2002, and later reauthorized in the Food, Conservation and Energy Act of 2008, the BioPreferred program was developed to increase the purchase and use of bio-based products to promote U.S. economic development by creating new jobs and providing new markets for farm commodities. It is also expected to help reduce foreign petroleum consumption, increase the use of renewable resources, better manage the carbon cycle, and contribute to reducing adverse environmental and health impacts. According to the USDA's definition, "Biobased products are commercial or industrial products (other than food or feed) that are composed in whole, or in significant part, of biological products, renewable agricultural materials
(including plant, animal, and marine materials) or forestry materials." Included as part of the BioPreferred program is a third-party product-labeling initiative, in which products are tested and required to meet or exceed the minimum biobased-content percentage in its given category. For example, insulation products must show that they are made from a minimum of 25% bio-based content to be included in the USDA’s catalog of BioPreferred products. If a product meets the requirements in its category, it receives an identification label that it can use on product packaging and marketing materials to help customers quickly discern products that meet BioPreferred standards. This labeling program is especially important to professionals who specify materials for new developments in the government sector. In February 2012, the Presidential Memorandum, “Driving Innovation and Creating Jobs in Rural America through Biobased and Sustainable Product Procurement” (http://www.whitehouse.gov/ the-press-office/2012/02/21/presidentialmemorandum-driving-innovation-and-creatingjobs-rural-ameri), mandated that at least 95% of applicable new contract actions for products and services advance sustainable acquisition, namely products that are thirdparty, BioPreferred-certified. Generally speaking, materials that earn the BioPreferred designation may also contribute to meeting criteria for other programs, such as the U.S. Green Building Council’s (Washington) Leadership in Energy and Environmental Design (LEED) or the International Green Construction Code. For example, use of Owens Corning’s, Columbus, OH, BioPreferred EcoTouch insulation helps architects and builders meet criteria of other green-building programs. This is especially beneficial when it comes

to specifying materials for projects that are required to comply with the 2012 Presidential Memorandum and are also designed to qualify for LEED certification or other green-building standards. As specifiers deal with responsible building and other prescriptive building initiatives, there’s no need to dread the product-selection process. Third-party labeling programs are increasingly helpful when it comes to specifying the right materials. Many of the programs, including BioPreferred, have online catalogs of qualifying materials or manufacturers, and various stamps, seals, and labels now appear directly on product packaging. In addition, product manufacturers are a good resource to help navigate the materials-selection process by addressing specific product questions and providing the up-to-date information as it pertains to the project at hand. Gale Tedhams is director of product and supply chain sustainability at Owens Corning, Columbus, OH.

Codes Rush To Keep Up With Green Boom
National and international groups are establishing more comprehensive and flexible criteria for green building.
T
he expanding global interest in green construction puts constant pressure on evolving standards. As new technologies debut and new opportunities become apparent, those setting regulations and criteria have to take a look at how the latest players change the game. One example: The next version of LEED is likely to include a credit for design and materials that minimize the chances of birds flying into glass windows and breaking their necks. That’s a whole new aspect of protecting the environment and ecosystem that might have seemed over the top not that long ago, but is now a valid concern. In this article, you’ll read about two of the largest programs currently in the works for future green buildings. LEED v4 is part of the ever-evolving LEED certification program. IgCC—the International Green Construction Code—will establish worldwide standards for commercial construction to encourage energy efficiency and sustainability.
LEED v4 Casts A Wider Net Release of LEED 2012 was delayed to accommodate enormous feedback and comments.
Casting a wider net Reflecting the fourth public-comment draft, LEED v4 focuses on increasing technical stringency from past versions and developing new requirements for projects such as data centers, warehouses and distribution centers, hotels and motels, existing schools, existing retail, and midrise residential. It also will be more compatible with international standards for LEED projects outside the U.S. Credits aimed at promoting higher performance outcomes are woven throughout LEED v4, addressed in every credit category, and integrated across all LEED programs. Comments on LEED v4 may be submitted through Dec. 10, 2012, using USGBC’s web-based forum. Every comment is reviewed, but it must be noted in the specific rating system: • Building Design + Construction and Interior Design + Construction propose changes for identifying synergies among building systems and using them to achieve improved system design and performance. • Existing Buildings: Operations & Maintenance proposes changes for ongoing building efficiency and sustainability and seeks to refocus the scope of requirements to be within the control of building management. Summaries for all of the proposed changes, by rating system, are available for download at www.usgbc.org/DisplayPage.aspx?CMSPage ID=2360. The current draft of LEED v4 also proposes various updates to credits within the LEED Pilot

s the saying goes, you can have it right, or you can have it fast, but you can’t have it right and fast. That philosophy seems to apply to the latest version of LEED, which was originally expected to be released this year. However, on Oct. 2, 2012, the U.S. Green Building Council (USGBC), Washington, opened a fifth public comment period on the highly anticipated updates to its LEED program. Launched by USGBC in 2000, LEED certification provides independent, thirdparty verification that a building was designed and built using strategies aimed at achieving high performance in key areas of human and environmental health. The LEED rating systems are developed through an open, consensus-based process and updated through a continuousimprovement process. LEED 2009 will be open for project registration until 2015. Since the first public comment period for LEED 2012 closed in January 2011, USGBC has received more than 21,000 comments. This overwhelming feedback delayed the ballot until 2013. Because of the date change, the update has been renamed LEED v4. “This is 100% in response to our members’ desire that we give them a bit more time to absorb the changes in this next version of the rating system,” said Rick Fedrizzi, USGBC’s president, CEO and founding chair. “We want to do everything we can to ensure that the market can fully embrace LEED v4 because it represents significant progress on carbon reduction and human health.”

feature GREEN CONSTRUCTION Credit Library. “As part of the larger evolution of the Materials & Resources credit category, the new pilot credits shift focus toward a more integrated decision-making framework based on life-cycle assessment,” said Brendan Owens, USGBC’s vice president for LEED technical development. The proposed changes include the following: • Under the heading of Materials & Resources (MR), Pilot Credits 2 and 11 will combine to form a more encompassing chemical-avoidance credit regarding building materials that contain chemicals known to negatively affect human health, specifically in regards to cancer and reproductive toxicity. An additional credit will address product transparency. • A new Energy Jumpstart concept, under the Energy & Atmosphere (EA) heading, addresses the opportunity to reduce carbon emissions and building operational expenses by reaching the 75% of the market that the existing-buildings energy-performance prerequisite excludes. • Ten additional pilot credits have been introduced into the library and can be viewed online at www.usgbc.org/pilotcreditlibrary. The library
currently contains 36 credits ranging from the life-cycle assessment of building assemblies to bird-collision deterrence. The LEED v4 beta test is an opportunity for project teams to help test the LEED v4 program before it is available for registration in the market. In direct response to market demand, the goal is to have project teams across market sectors engage with a pre-ballot version of LEED v4 to help USGBC improve aspects of the LEED v4 program and identify challenges with proposed documentation, as well as areas in need of additional education development. Project teams interested in participating in the beta testing should email LEEDv4@usgbc.org for more information.
Building green is booming As of July 2012, nearly 50,000 commercial projects currently are participating in LEED, comprising 9 billion sq. ft. of construction space. The total footprint of LEED-certified commercial projects has surpassed 2 billion sq. ft. Across the globe, an additional 7 billion sq. ft. are currently in the pipeline as registered projects. Each day, 2 million

sq. ft. of commercial building space, in more than 130 countries, achieves LEED certification. To foster understanding about the current draft, public forums and educational sessions will be held Nov. 14 through 16 during the 2012 Greenbuild International Conference and Expo in San Francisco. At the conference, USGBC also will debut new forms, submittal documents, LEED Online enhancements, and other infrastructural upgrades. While some may be disappointed about the delay of the newest version of LEED, few will argue that the extended time for comments and ideas will result in a less meaningful product. Continuous improvement is, after all, continuous. According to architect and leading green-building advocate William A. McDonough, “Sustainability takes forever. And that’s the point.” Heather West, Heather West Public Relations Inc., Minneapolis, specializes in writing about energy efficiency, water efficiency, and highperformance buildings.

his year has ushered in a new era of building-code changes, with enhancements focused primarily on higher levels of energy efficiency. Their impact on the commercial-construction industry is quite significant. Perhaps the most noteworthy are those prescribed in the 2012 International Energy Conservation Code (IECC), which calls for buildings to achieve a 30% increase in energy efficiencies over the 2006 IECC. This sixth edition of the code illustrates the growing importance of ensuring that all buildings are achieving high levels of energy efficiency in congruence with model building codes such as the International Building Code. According to the Washington-based International Code Council (ICC), this comprehensive set of changes includes measures to improve the building envelope, HVAC systems, and electrical systems of residential buildings as tall as three stories. Commercial-building enhancements include required energy efficiency for windows, doors, skylights, the building envelope, and increased efficiencies for installed HVAC equipment.

feature GREEN CONSTRUCTION to reduce the negative effects of the built environment on the natural environment, the IgCC was created by a broad-based committee with experts in areas such as government, business, academia, code development/enforcement, engineering, and environmental advocacy. The IgCC goes beyond traditional life/safety model codes and simulates some voluntary program requirements for commercial buildings to provide safe and sustainable facilities. It incorporates sustainable practices within existing building codes at the state and/or jurisdictional level. One noteworthy aspect of IgCC is the flexibility it offers architects, contractors, and building owners. For instance, they can choose to comply with either the Material Selection mandate (not less than 55% of the total building materials should be used, recycled, and/or recyclable materials) or the Whole Building Lifecycle assessment. If the latter is used, the building project must achieve at least a 20% improvement in environmental performance for global warming potential, among other measures. Scheduled for release in less than a year is LEED v4 (formerly LEED 2012), the next version of the LEED rating systems. The new version will likely favor a more-holistic, life-cycle approach for products installed in LEED-certified buildings and assemblies and will reward transparency for sustainable manufacturing, socially responsible raw-materials sourcing, and use of products with low-VOC emissions. As with IgCC, LEED v4 seems likely to reward a building’s overall environmental effectiveness and not limit it to the measurement and assessment of various piece parts—another example of the holistic approach to energy—and environment-oriented building codes.
Greener building envelopes These new or revised codes and programs reveal the shift toward increased energy efficiency and environmental awareness not seen in previous codes. They also are generally intended as overlay codes, designed to work in partnership with existing construction codes. However, an interesting and potentially challenging aspect of IgCC is that it addresses many areas that have not been typically applied by earlier building codes. For instance, the code has many specific provisions with respect to site development and land use—new ground for construction codes. The impact of these new and updated codes reinforces the importance of holistically addressing energy efficiencies and environmental impact throughout a building and its environs. They also reinforce the overall importance of high-performance roofing systems as part of the building envelope. Now, more than ever, a well-insulated and well-protected roof is criti12

cal for new or renovated commercial buildings. Without that protection, the rest of the building envelope cannot perform at peak efficiency. Beyond the pragmatic need to maximize energy efficiencies, code and program language is defining roofing’s emerging role. Commercial roofs have become multi-use platforms that house an array of renewable-energy systems and
Designed and constructed to meet LEED criteria, the Student Union Building at the State University of New York (SUNY) at New Paltz transformed an existing 1970s concrete building and an underused courtyard into a welcoming winter garden encased in metal and glass. Daylighting, outside views, recyclable materials, thermal comfort, and interior air quality are other examples of the many aspects that contribute to the project’s sustainability goals.

environmental features, such as photovoltaic (PV) and vegetative roofs. These emerging assemblies, while enhancing the environmental and energy performance of a building, have added considerably to the foot traffic of the modern commercial roof. By definition, the very function of a roof is to protect a building and its contents. When additional equipment, PV panels, or vegetation are installed and need to be maintained, it results in more

roof foot traffic overall. These types of roof assemblies will bear a more taxing load that could stress the roofing systems beyond their normal capabilities. Add to that the economic risk that leaks, cracks, and other damage could impart, and the value and importance of sustainable, durable, and high-performing roofs grows exponentially. Whatever products you choose, be certain to select a durable cover board to protect the insulation needed for energy-code and buildingprogram roof assembly R-values. While the prescriptive R-values vary by climate zone, every code or program requires some level of continuous insulation above the deck. The greater the insulation, the more roof protection makes sense. While several roof cover-board materials are available to contractors, fiberglass-mat gypsum roofing boards, such as DensDeck roof boards from Georgia-Pacific, Atlanta, have proven to be among the most effective. For more than 25 years, these panels have been shown to withstand delamination, deterioration, warping, and job-site damage far more effectively than paper-faced gypsum board or other conventional roofing products. Similarly, other components of the building envelope—such as exterior sheathing, interior walls/ceilings, shaftwalls, and stairwells—must be similarly durable and resistant to damage during and after construction to maintain energyefficiency and sustainability requirements. Given the economic impact of heightened energy and environmental requirements, fiberglassmat gypsum panels, such as those in the Dens product line, are particularly effective if installed throughout the envelope. Because the panels are designed to resist mold and don’t deteriorate like paper-faced panels when exposed to ambient moisture during a normal construction cycle, they can be installed before doors, windows, or even roofing. While the benefits of IgCC and other energyoriented codes are quite evident, their impact on the selection and installation of building materials is quite substantial. Be sure to refresh your knowledge of these and existing codes, especially in jurisdictions that have or are expected to adopt them. Doing so will ease the burden and protect the budget for all of your construction projects. Barry Reid, LEED AP BD&C, is sustainability/ product manager for Georgia-Pacific Gypsum, Atlanta.

deas about glass walls have been around since at least 1914, when architect, author, and artist Paul Scheerbart contemplated glass as an interior-wall solution and earned a place as one of the fathers of the glass-wall industry. In the 21st century, glass walls are all the rage, even inspiring The Wall Street Journal, New York, to publish an article about glass walls, open workspaces, and the effects on privacy. How did we get to a place where a major business publication would feature a material choice for walls in commercial interiors? This dramatic increase in the amount of glass used in commercial interiors appears to be driven by three factors: new thinking on office environments including the health and wellbeing of building occupants, increased interest in using more sustainable materials, and lowering the overall energy costs of buildings.
New design thinking The philosophy behind interior design, particularly in commercial offices, has changed dramatically over the past several years. New principles have 14

Glass walls make a difference in productivity, aesthetics, and energy costs. Diane Turnwall, Guardian Industries led to an increase in the amount of glass usage as well as its locations. In years past, private offices lined the exterior walls of a building, preventing light from penetrating the center of a space. Today’s work requires increased collaboration. In a recent office consolidation of telecommunications provider Telus, Toronto, designers used glass fronts on offices and meeting rooms to clearly communicate the company’s desire for an open and collaborative work style. The visual openness invites participation, increasing the knowledge transfer within an organization that is linked to the speed of innovation.

Today’s workers are more mobile, thanks to advances in technology. In the past, every office worker was assigned an individual space, whether that space was in the open or private. Today, spaces can be shared, as they are at Horizon Healthcare Services Corporate Strategy and Development, Newark, NJ. Glass walls in its new space share access to natural light and are an active demonstration of the company’s space-sharing approach. “When I’m not in my office, anyone can use it as a conference room. This isn’t my space; it’s a community space,” said Donna Celestini, vice president of strategy and development. This increased visual access to natural light, colleagues, and work in progress improves results and gives all building occupants an increased sense of well-being. In fact, the LEED Indoor Environmental Quality Credit for Daylighting and Views provides one point for functional daylighting that reaches 75% of regularly occupied spaces. There are some fascinating studies about the positive effects of daylighting on building

The authors of a study published in the American Journal of Public Health, Washington, surveyed 263 people as they moved into new workplaces that had achieved either LEED Gold or LEED Platinum. Daylight and views were described in connection with lighting, acoustics, and ergonomic design and safety, linking them to well-being issues of depression, stress, and productivity. The reported benefits of the new “green” workplace, which took into account all of the physical attributes of the space, included: • an additional 2.02 work hours/occupant having previously reported stress or depression • an additional 38.98 work hours/occupant due to an improvement in productivity of 2.6% for all occupants.

It reduces the amount of materials and finishes, which can decrease the level of toxins and improve air quality, in addition to creating an entirely new look that melds natural light with existing amenities. An upgrade that adds glass walls to an aging or empty office building will make it attractive to potential renters. Healthcare environments have been unrealistically portrayed in TV shows as having glass walls in private areas. While you’d be hard-pressed to find patient rooms with completely transparent walls in the real world,
Sustainable material Glass has become a more affordable choice as organizations take a holistic view of the total costs of interiors. More than 20 years ago, virtually all walls used in an office were constructed of drywall or plaster. Adding additional functional or aesthetic features such as wood paneling or glass sidelights were costly. Changing any of the walls was costly, disruptive, and resulted in a great deal of material being hauled to a landfill. In terms of sustainability, gypsum-board installations require multiple materials and on-site finishing, and they create construction waste. In addition to the disposal costs and variable labor expense, drywall partitions typically must meet local codes for electrical systems. Wall manufacturers have been making moveable products for many years, but recent improvements in designs and options have increased their use. These enhancements have made glass a smart choice because it is reusable and can be reconfigured as the needs of an organization change. Using glass is more affordable than ever. Retrofits are a great opportunity to incorporate glass walls. Glass walls eliminate many of the negatives associated with drywall installation: a slow, disruptive process that causes dust and often requires temporarily moving occupants to new spaces. Cleaner installation gives glass an advantage over 16

fact, the Whole Building Design Guide from the National Institute of Building Sciences, Washington, states that a mere 1% savings in productivity can come close to offsetting a company’s annual energy costs. Interior glass harvests daylight. An office building might currently have a conference room on the south end of the building. However, the abundant sunlight coming through the windows most of the year is just hitting the north wall. If that conference room has a glass north wall, it pulls light into the core of the building.

it is a growing possibility due to the variety of textured, etched, and colored glass that wasn’t available a few years ago. These variations on clear glass provide privacy while pulling the well-documented healing characteristics of daylighting into a facility. Interior glass plays an important role in public spaces, much to the delight of staff. A 2008 study showed that nurses exposed to daylight for three or more hours each day reported less work stress.
Green buildings The benefits of using glass are intuitive when considering design and reusability, but its use in interiors also lowers overall energy costs.

Increasing the use of gglass is perceived to require some tradeoffs such as sacrificing durability for light or privacy for increased levels of openness. But glass has innovative solutions to address many of the perceived issues of installing glass in building interiors. Glass walls can help maximize the space in small rooms and provide some boundary control while still providing visual access to the space beyond the glass wall. These spaces can achieve more privacy through a variety of glass products, all of which take the upscale, modern, sleek look of clear glass and modify it to beautiful effect. Interior designers have shown tremendous creativity in using this material because of numerous available options: • Acid-etched glass provides a soft, diffused light with a consistent surface. It will transmit almost as much light as clear glass, but one can only see shadows through the glass to provide visual privacy. It’s also fingerprint-resistant. • Laminated glass is available in any color of the rainbow, because the polyvinyl-butyral (PVB) interlayer used to permanently bond the

feature INTERIORS two pieces of glass together can be colored. • Pattern glass also gives privacy, but with a completely different effect. Light passes through but is transformed by depth and dimension to create a beautiful appearance. • Silk-screened glass is produced when a ceramic frit is applied to the glass. Available in a variety of colors and patterns, it offers moderate privacy with a unique appearance. • Back-painted glass is brightly opaque, brilliantly stunning glass. Customized colors allow the brand to be present in subtle but consistent ways. The paint can be applied to large sheets of glass and cut to size for cost-effective fabrication, making it more accessible and affordable. The paint coating also strengthens the glass. • Tinted-glass products provide color and change light transmission, depending on the color’s depth. • Switchable glass has a special film laminated between two layers of glass that can change from opaque to transparent when electric current is applied. This glass is very effective in environments that sometimes require privacy, such as conference rooms or private offices. Specifiers should consider a wall’s acoustic properties for working environments with privacy concerns, such as healthcare settings, financial companies, and human-resources offices. Acoustics are typically measured by STC (sound transmission class) and OITC (outdoor/ indoor transmission class) based on sound wavelength. Sound transmission can be affected by many elements of a wall’s construction, including type of material, use of insulation, and wall height. Similarly glass walls’ acoustic properties vary based on their construction. For those spaces requiring a higher degree of privacy, laminated glass provides the best acoustical performance, due to the interlayer, which
provides a vibration-dampening effect. Increasing the glass thickness also increases the sound buffer.
Safety, durability, and care The most important consideration when choosing the right glass for interiors is safety. Architects and builders should look first to tempered or laminated glass. Tempering increases glass strength by a factor of four, compared with standard annealed glass. Tempered glass is considered safety glass because when it breaks, it shatters into relatively small pieces instead of large shards. Laminated glass provides a strong barrier against objects that could otherwise penetrate a glass wall. The PVB interlayer provides a safety layer: When the glass breaks, the PVB will tend to hold the broken pieces together, as in a car windshield. Depending on the type of PVB used, laminated glass can provide a highsecurity solution, as well as provide the strongest acoustical barrier of the different types of glass. Regardless of tempered, laminated, color, or texture, glass offers a very long life cycle. However, glass that is not coated is subject to scratches from contact with anything abrasive and through normal wear and tear. Consider sealing the glass with a coating that creates a scratch-resistant surface and requires no special products to maintain its appearance. Current high-performance coatings can be cleaned with standard cleaning products. Glass manufacturers, fabricators, and glaziers have worked to create fruitful partnerships that inject the cost controls and reliability needed for projects, no matter how large or small. Other recent advancements include a plethora of online tools that make it easy for designers to get inspiration, compare products, and easily organize presentations for

reen roofs have been around, in one form or another, for more than 2,000 years, stretching all the way back to the legendary Hanging Gardens of Babylon. More than 30 years ago, Europeans, particularly Germans, began making extensive use of green roofs. Today, there are hundreds of millions of square feet installed worldwide. These lightweight, low-cost, and lowmaintenance systems hold the promise of becoming a new and highly valuable form of infrastructure in our cities because they deliver a multitude of social, economic, and environmental benefits. A green roof, by definition, is a contained green space on top of a human-made structure. This green space could be below, at, or above grade, but in no case is the vegetation planted in the ground. A green-roof system is an extension of the existing roof, involving a high-quality waterproof/root-repellent system, a drainage system, filter cloth, a lightweight growing medium, and carefully selected plants. Green-roof systems may be modular, with drainage layers, filter cloth, growing media, and plants already prepared in movable, often interlocking grids or they can use a loose-laid approach in which each component is installed separately. Green roofs provide a wide range of public and private benefits. The nature of the benefits depends on factors such as the type of system, climate, project design objectives, budget, structural-load capacity, building surroundings, and building type. The benefits and economic savings that can result from green roofs are quite astounding and continue to evolve with research developments and overall growth. 20

Multiple advantages Every green roof provides basic infrastructure services such as storm-water management by delaying it from reaching storm sewers, slowing its movement to storm sewers, and retaining a percentage of rainfall. Storm water is a massive, multi-billion dollar infrastructure challenge, with trillions of gallons of untreated storm water from roofs, parking lots, and streets contaminating rivers, lakes, and estuaries each year. Cities such as Philadelphia, Milwaukee, and New York have begun to look to green-infrastructure solutions such as urban forests, green roofs and walls, bioswales, and wetlands as new approaches to try to address this and other urban challenges. The City of Philadelphia’s Green Cities, Clean Waters Plan, recently approved by the Environmental Protection Agency, Washington, calls for billions in investment to support the establishment of 9,000 green acres over 25 years to address stormwater challenges. Green roofs also replace what is often a source of heat—a hot roof—with a natural, outdoor air conditioner. This helps reduce the urban heat-island effect in cities, the phenomenon whereby removing vegetation results in much higher temperatures than in the surrounding countryside. Higher temperatures, by as much as 9 F, significantly increase the demand on HVAC systems, generate ground-level ozone and other air pollutants, negatively affect tourism, contribute to drought, and have a negative impact on human health and well-being. Green roofs capture and retain water in the plants, growing media, and drainage layers. Instead

of converting the incoming solar radiation into heat, the water evaporates and transpires into the surrounding atmosphere using the sun’s energy. A black roof can reach temperatures as high as 170 F. A healthy green roof, which will not exceed 75 F, actually cools the area around the building. Vegetation from green roofs and green walls improves air quality in several ways. The rough surfaces of the leaves of plants trap dust and particulate matter. Hot air slows when passing over the cool column of air above a green roof and drops particulates. The plants are then able to absorb and metabolize pollutants such as nitrous oxides. Another important infrastructure benefit is the ability to generate more lasting green jobs for each public dollar invested than other infrastructure investments. Green roofs are not imported and many of the materials used can often be sourced within 500 miles of the project. Green roofs are labor-intensive and require ongoing maintenance, which means lasting employment. Some projects, typically larger, intensive green roofs that use large amounts of growing media and a wide variety of plants, can generate additional jobs. One emerging trend is to use rooftops to grow food in cities, thereby providing additional employment associated with the planting, maintaining, harvesting, processing, sale, and distribution of produce. Other green-roof projects provide critical amenity space, such as Millennium Park in Chicago. Hospitals are building green roofs to provide opportunities for patients to heal through emerging practices such as horticultural therapy and to help relieve stressed staff. Commercial-building owners are adding green roofs
as amenity spaces with full or partial access for tenants because an increasing body of literature shows greater productivity—as much as 10% higher—and less absenteeism when natural features are incorporated into buildings. These types of green roofs produce a multitude of interlocking employment-related benefits, many of which have direct bottom-line benefits for governments and private-sector building owners.
Growing more roofs Since 2004, Green Roofs for Healthy Cities (GRHC), the North American green roof and wall industry association based in Toronto, has conducted an independent survey of its corporate members, collecting data on the growth and composition of the green-roof industry across North America. The industry has grown steadily, but the 2012 Green Roof Industry Survey found the North American industry grew by 115% in 2011, compared with 2010 when the growth rate was 28.5%. Every year, Chicago has been at the forefront of green-roof policy development. Chicago, which boasts more than 5 million sq. ft. of green roofs, has provided a range of financial and regulatory incentives for green-roof development. These include fast-tracking development permits, requirements to install green roofs when government
floor area. The city also implemented a detailed construction standard that governs the design, installation, and maintenance of green roofs throughout the city.
Going pro Local- and regional-government support, through policies and incentives, has undoubtedly aided success in these leading cities. The significant growth is also a function of the dedication of the hundreds of people who work in the field. In 2009, GRHC launched an accreditation program after six years of development involving a multitude of experts. The Green Roof Professional (GRP) accreditation program establishes a benchmark for the multi-disciplinary knowledge that is required to successfully design, install, and maintain a green-roof system. The training focuses on the benefits of green roofs, best practices, and problems that can arise and how to avoid or address them. The GRP program is designed to help reduce green-roof failure by establishing best practices and promoting education. It also recognizes the more than 500 professionals who have earned the right to call themselves GRPs. Policy makers have even begun to use the GRP designation as an approach to help ensure that projects are properly executed, and developers have begun to
demand that GRPs be part of project teams. In an era of enormous budget deficits and bankrupt cities and towns, we need to spend each and every public and private dollar as wisely as possible. Living-architecture technologies, such as green roofs and walls, hold the promise of contributing significantly to the green-building movement and to the broader infrastructure challenges facing our country. They are able to do this because they reach across traditional divides between professionals and government departments and make use of underused spaces—the roofs and walls of our cities. Unlike many forms of infrastructure, they bring a multitude of solutions to the table: clean air and water, jobs, efficiency, community health, and opportunities to simply relax and enjoy our increasingly urban lives. Steven W. Peck, GRP, Honorary ASLA, is the founder and president of Green Roofs for Healthy Cities, Toronto, an industry association whose mission is to develop the industry across North America.

ngineers love solar energy, but the same can’t always be said for architects. Most architects believe solar energy is essential to the world’s progress toward sustainability, but they also see solar as an unsightly distraction to their architectural works of art—and in many cases they’re right. It’s no secret that few solar applications are well-integrated into the building design. Solar water heating involves rooftop solar panels, and solarelectric generation uses photovoltaic (PV) cells that may not be concealable. Additionally, there are piping and other visible support structures that protrude and detract from the clean lines of a building’s architecture. Solar retrofits are especially unaesthetic, typically added without considering a building’s architecture. Despite a lot of effort toward making solarenergy generation more aesthetically pleasing, even new-construction solar water and PV installations don’t blend well with a facility’s architecture. Many solar-project decisions are based on payback, which mandates functionality, regardless of form. While solar energy has been typified

In buildings where air comfort is more critical for occupants, such as offices, hospitals, and schools, warm air is drawn into the facility’s HVAC system by a thermostatically controlled damper, mixed with conditioned air, and distributed through the building’s ductwork system. Depending on the size of the facility, geographic location, and heating needs, a wall-mounted solar collector can provide a significant percentage of pre-heated outdoorair needs throughout the winter.

In new construction, a solar air collector can provide almost immediate payback when it is designed as an alternative to a masonry wall. Brick walls, for example, cost approximately $26/sq. ft. Substituting a metal wall collector with glazing panels on top is significantly less expensive. The metal wall, which most architects dislike for its industrial appearance, “disappears” behind the glazing. Therefore, the solar collector looks like a wall of windows while offering years of energy savings. Planning with the mechanical engineer to place the building’s rooftop or ground-level HVAC system near the wall-mounted solar collector reduces ductwork-integration costs. The world’s third largest aircraft manufacturer, Bombardier, Montreal, used a wall-mounted solar air heater in a retrofit to preheat outdoor air at one of many plants it operates in North America. Previously, solar wasn’t an option for its green mission because the publicly held company’s two-year-payback criterion limits the consideration of many alternative-energy concepts. However, at the company’s 40,000-sq.-ft. Mirabel, Quebec, research-and-development facility, the plant’s engineering group authorized the installation of a Lubi wall-mounted solar air heater from Enerconcept Technologies Inc., Magog, Quebec. With its perforated glazing, it demonstrates the highest efficiency of any solar device. Serge Dumont, P.E., engineering and tooling manager at the plant, selected the Lubi because it demonstrated a two-year payback was possible after incentives by Natural Resources Canada (NRC) and a rebate from the Energy Efficiency Fund (EEF) of natural gas utility Gaz Metro. The 145-foot by 12-foot solar collector, which covers about 25% of the 7,600-sq.-ft.
masonry wall, supplements an existing naturalgas-fired make-up air unit by preheating wintertime outdoor air for the 52-foot-tall, hangarstyle building. The solar retrofit is delivering an annual 16-ton reduction of CO2 emissions and a $5,000 (Canadian) natural-gas savings. Over the course of its expected minimum 20-year life, the natural-gas savings will undoubtedly rise well past $100,000 when considering inevitable fossilfuel price escalations.
Beauty as it heats From an aesthetics perspective, the Mirabel solar collector appears to be rows of windows atop the building wall. The challenge of integrating the collector with the rooftop ductwork air-distribution system was creatively solved by topping the collector with a parapet that looks like an architectural embellishment while it conceals the ductwork connection. Besides parapets, wall-mounted solar collectors offer many other design options. They can: • circumvent nearly any building feature imaginable, such as columns and windows • follow unusual forms such as curved walls to any degree of radius • form shapes by massing the 1-foot by 3-foot panels in the case of glazed collectors • take on unusual decorative shapes, such as a company logo or geographic design • provide custom colors to match any building exterior or corporate colors • match the metal backing to building exteriors or the glazing material itself • match the dampers and louvers, which are sometimes seen through the glass, to the building • be mounted on penthouses and rooftop mechanical rooms • be mounted on 45-degree or gable-style roofs to look like skylights. Architects usually gravitate toward glazed versions because of the glass-like appearance. For best solar performance, metal must be painted a dark color that might not complement the color scheme of the building. The fact that glazed solar collectors work with white or lighter colors offers architects and building owners yet more design flexibility.
High-performance solar The emergence of glazed solar collectors has also increased the performance of wall-mounted solar. Perforated glazing collectors outperform their metal counterparts by 20% on a black wall and 58% on a white wall. Compared with other solar technologies, solar air pre-heaters outperform solar water heaters by 25% and photovoltaic by 75% on the basis of kWh delivered/surface area. The Lubi panel, in particular, reaches 80.7% peak heating efficiencies, which is the highest
efficiency recorded for any solar air technology, according to certification tests by the Canadian Standards Association, Mississauga, Ontario. It produces temperature increases as high as 81 F above ambient outdoor temperatures and is rated as the world’s most efficient solar equipment by the National Solar Test Facility, a Mississaugabased third-party laboratory. Unlike wall-mounted metal solar collectors that suffer significant thermal losses on their exterior metal surfaces, perforated glazing panels greatly reduce thermal loss because of their transparency and the cooling effect of outdoor ambient air being drawn through the perforations by the building’s HVAC air-handling system. The cooler outdoor air traps the heated air behind the panel. Perforated translucent panels are 58% and 18% more efficient with black buildings and white buildings, respectively, compared with other wall-mounted solar collectors. At Plastech Inc., a Sherbrooke, Quebec, manufacturer of thermoplastic components, residual heat from injection-molding processes provided free heating to the 26,000-sq.-ft. production area. However, the 5,500-sq.-ft. shipping area used $6,000 annually in propane-heating costs for employee comfort. Company managers wanted a wall-mounted solar collector to heat the shipping area, but didn’t want to paint its modern white-metal building a darker color or hang a darker collector on the wall, so they chose a Lubi solar collector with transparent panels that match the building. A white collector is 40% less efficient than a darker model, but engineers offset that disadvantage by installing a collector that covers 40% more of the 200-foot by 24-foot wall. Temperature increases of 55 F were recorded over the most recent heating season. Payback is estimated at approximately four years after incentives from NRC and a rebate from Gaz Metro’s EEF. The emergence of wall-mounted solar, metal and glazed, is good news for architects. Instead of avoiding solar products because of poor aesthetics, architects can now integrate wallmounted solar products with a building. Perforated glazed solar collectors can be a high-payback feature that looks like a wall of windows while saving energy and reducing carbon emissions.

n 2011, the U.S. saw record numbers of tornadoes and, tragically, record numbers of related fatalities and injuries. The 2012 tornado season continued that trend with a record number of fatalities caused by such storms as early as January. One must ask if anything can be done to better protect buildings and their occupants from tornadoes, which can produce wind speeds of 250 mph or more. Adequate protective-construction standards do exist, notably as FEMA 361 (2008), Design and Construction Guidance for Community Saferooms, and the interrelated ICC 500-08, Standard for the Design and Construction of Storm Shelters. While these standards specifically address designated storm shelters, many experts recommend that essential facilities, such as hospitals and fire/rescue stations, should be built to these standards. An architect’s challenge is to include storm protection without eliminating glass or other cladding that enhances a building’s aesthetics. FEMA 361 and ICC 500 allow windows that are tested for structural integrity and debris impact at tornadic wind speeds and are shielded by louvers or other protective devices. However, these requirements do not address all windowperformance aspects of a functional building.

Planning for the unexpected In response, the American Architectural Manufacturers Association (AAMA), Schaumburg, IL, has published AAMA 512-11, Voluntary Specifications for Tornado-Hazard-Mitigating Fenestration Products. The document provides a system for testing and rating the ability of windows and their anchorage to withstand the extreme wind loading, debris impact, and water penetration typical of tornadoes. AAMA 512 adapts testing parameters developed for the protection levels and geographical wind zones described by ICC 500 and FEMA 361 tornado wind-zone charts. It is applicable to the fenestration of any building for which maximum practical tornado-protective design is specified. As a prerequisite, any product seeking an AAMA 512 rating must first satisfy the requirements for a minimum AW60 rating in accordance with the North American Fenestration Standard/Specification for windows, doors, and skylights (AAMA/WDMA/CSA 101/I.S.2/A440, NAFS). Curtain wall, storefront, and sloped glazing, which are outside the scope of NAFS, may also be tested to AAMA 512 requirements as long as they have met the requirements of the project specifications according to ASCE-7, Minimum Design Loads of Buildings and Other
Structures, or the minimum requirements of AAMA 501, Methods of Test for Exterior Walls. Once a product achieves the prerequisite performance requirements, it’s ready for impact testing for protection against wind-borne debris from hurricanes (ASTM E1996, Standard Specification for Performance of Exterior Windows, Curtain Walls, Doors, and Impact Protective Systems Impacted by Windborne Debris in Hurricanes). The test impels a 15-pound length of 2-foot by 4-foot lumber into a test window at as much as 100 mph. Products for use in areas that are also prone to hurricanes should be tested for pressure-cycling resistance according to ASTM E1996 as well as ASTM E1886, Standard Test Method for Performance of Exterior Windows, Curtain Walls, Doors, and Impact Protective Systems Impacted by Missile(s) and Exposed to Cyclic Pressure Differentials.

Levels of protection The Federal Emergency Management Agency (FEMA), Washington, designates two protection levels: • Level 1: (Operational) The facility is essentially undamaged, and can be immediately operational. Level 1 water-penetration testing is exclusively for the installation method tested. • Level 2: (Moderate Damage) The facility is damaged and needs some repairs, but it can remain occupied and functional after minor

repairs to non-structural components. For products seeking a Protection Level 1 rating, AAMA 512 requires testing for water penetration as described in AAMA 520-09, Voluntary Specification for Rating the Severe Wind-Driven Rain Resistance of Windows, Doors, and Unit Skylights. Originally developed for testing water-penetration resistance under exposure to hurricane wind-driven deluges, AAMA 520 calls for testing to the standards of ASTM E 2268, Standard Test Method for Water
Tornado Missile Speed
Impact
Water Penetration
Penetration of Exterior Windows, Skylights and Doors by Rapid Pulsed Air Pressure Difference. AAMA 512 uses these test results to assign a two-part rating code signifying the FEMA Level of Protection and Wind Hazard Zone applicable to the location. For example, 1ZIII would indicate a window designed and tested for FEMA Level 1 protection if used in Wind Hazard Zone III. (See Table 1.) Test-specimen anchorage to the building substrate (aluminum, steel, concrete, masonry, or wood) must be in accordance with applicable industry standards for the specific substrate, as described in AAMA 512. A licensed professional engineer must review and stamp installation details, including anchorage, for the test report. While the largest test-specimen size typically presents the worst case for a window system, this is not necessarily true for tornadomitigating products. Paths for energy absorption vary considerably depending on additional factors such as configuration, aspect ratio, hardware location, and anchor rigidity and substrate. Accordingly, smaller sizes and different configurations can only be qualified by engineering analysis in accordance with AAMA 2501, Voluntary Guideline for Engineering Analysis of Window and Sliding Glass
Door Anchorage Systems, and AAMA 2502, Comparative Analysis Procedure for Window and Door Products. Table 2 compares the application of these standards and test/analysis methods for withstanding hurricanes and tornadoes. Clearly, if an EF-4 or EF-5 tornado levels an entire building, it makes little difference how well its windows perform. However, hazardmitigation opportunities do exist for buildings exposed to the most common tornadoes. AAMA 512 complements existing building standards by providing a method for rating fenestration products to withstand disastrous events—or at least keep them from being quite so disastrous.

He has served on standards and certification committees of a dozen national and international organizations, including government.

ENERGY SOLUTIONS FOR COMMERCIAL BUILDINGS
High-performance daylighting in educational spaces has been proven to increase student productivity by 20% in math and 26% in reading while reducing absenteeism by as much as 80%. High-performance schools demand high-performance daylighted spaces.
Combine H Daylight, LEDs, Avoid Glare Daylighting systems that marry sunlight and LED fixtures are energy misers, but poor design can steal those energy savings. Seth Warren Rose, Eneref Institute
igh-performance buildings require daylight. It plays a major role in energy savings and workenvironment quality. The human-productivity gains from daylighting alone are often significant. It is well-established that ample amounts of daylight boost student productivity, reduce worker absenteeism, and increase retail-store sales. Human-performance numbers in daylighting systems are important because the ROI for daylighting installations can sometimes be a difficult sell. However, the human-performance gains can outweigh the energy savings when human performance is measured in financial terms. Daylighting’s low-hanging fruit are facilities with open or drop ceilings, such as large retail stores, commercial offices, and schools. Depending on energy costs, daylighting systems can offer a five-year ROI or less. But no building can function with the sun as its sole lighting source. From a pure energy-consumption perspective, the best daylighting package appears to be a system that combines sunlight with LED fi xtures and a well-designed lighting-control system. We are witnessing encouraging growth in the implementation of these types of systems. They potentially offer significant energy savings while retaining the humanperformance benefits that sunlight provides. But the challenge is to deliver maximum amounts of light to a space without introducing excessive glare.
Delivering the light The trick to designing a good daylighting system is balance, i.e., to harvest and deliver the greatest amount of daylight to the workspace without hot 28

spots or coronas. The more daylight delivered into a space, the better the system’s ROI. Better reflectors are especially crucial in a tubular daylighting device where sunlight travels from a roof, around obstructions, and down to a suspended ceiling, requiring additional bounces to reach the room interior. Reflector-material quality is crucial because each time daylight bounces off of a reflector, some light is lost. The more reflective the material, the less light the material absorbs. Therefore, systems with better reflector material naturally make better daylighting systems. The other main cause of lost daylight is diffuser lenses. While critical to reduce glare, a poorly designed diffuser lens can sacrifice an additional 10% to 30% of daylight. Sunoptics Prismatic Skylights, Sacramento, CA, recently introduced the LightFlex daylighting system for suspended-ceiling applications. It combines many of the components needed for an efficient tubular daylighting device. The system manages to capture and deliver a maximum amount of daylight by harvesting the sun with a prismatic skylight and internal optic sphere on the roof. Light then passes through a tube made with highly reflective Miro aluminum made by Alanod GmbH & Co., Newnan, GA. To avoid glare, the system uses a variety of optically designed diffuser-lens options to distribute light to match a host of electric lighting products designed for the same space.
Cut LED glare While any daylighting system offers energy savings, a recent study by Eneref Institute, Doylestown, PA,
AUTHOR Seth Warren Rose is the executive director of the Eneref Institute, Doylestown, PA, a leading sustainable-development think tank.
▲ Like this new Walmart Supercenter in West Sacramento, CA, retailers are increasingly using high-performance daylighting and lighting controls to reduce operational expenditures and increase sales.
Daylighting systems with motion and photo control reduce electricity consumption by as much as 80% during daylight hours in warehouses and distribution centers. ▲
found increased incidence of glare in some lower-end daylighting/LED systems, when compared with the fluorescent- and high-intensity-discharge-based systems they replaced. Glare and poor lighting in general can diminish the performance of building occupants. In fact, when human performance is measured in pure economic terms, poor light quality can eliminate the energy savings that daylighting/LED systems provide. Typically a manufacturer’s solution to glare in LEDs and daylighting fi xtures is to use light-diffusing lenses to hide the light source. Lenses, by their nature, block light that the system creates. Better light-diffusing lenses destroy less light. Plastic lens shields reduce glare but at the cost of reducing the light energy. Some lenses may not hide the appearance of a single LED fi xture or they may grow more opaque over time and thereby reduce efficiency. Therefore, tomorrow’s LED lighting systems may need to take a different approach to reducing glare than daylighting systems use. Instead of lenses, some lighting manufacturers point LEDs away from the occupant and into an efficient reflector. This solution shields eyes from direct view of the bright LEDs. It also hides the glare of direct LED light, while using the specularity of the reflective material to control the light distribution, using the reflector shape to spread or focus the light beam as needed. The most efficient reflective material is highly reflective and specular. Reflectivity is measured by the amount of light that bounces off the reflector’s surface. Today, silver specular materials approach 98% reflectivity. When the reflector shape is faceted in a complex design to maximize light distribution or when the LED is positioned deep within the surrounding reflector, the reflective material’s specular properties are most crucial. To reduce glare, some reflectors are designed in a way that the light bounces around inside the fi xture a few times before it exits. If three bounces are required before the light leaves the fi xture, the fi xture loses 2% three times for a total of 94.1% of effective light energy. But with an 86% reflective material, the amount of light coming out of the fi xture diminishes quickly after three bounces, down to 63.6% of effective light. Over the next few years the market will introduce increasingly powerful LED fi xtures. But if you have to squint when they’re on to avoid the glare, they are probably not going to be the best lighting solution. BP

CalStar permeable pavers provide clear delineation for areas at the Milwaukee Farmers Market. The sustainable pavers require less energy to produce, along with emitting less CO2, than traditional clay pavers. ▲
Green And Healthy Pavers transform a community space with style and sustainability.
T
he 11,000-sq.-ft. Farmers Market plaza in Milwaukee’s Garden District is more than just an elegant gathering space for promoting healthy, local buying. It’s also the anchor of a community-wide effort to promote sustainable technologies and transform a neighborhood. The idea began three years ago when landscaper Bryan Simon, owner of Simon Landscape Co., Milwaukee, founded the nonprofit Energy Exchange with the goal of educating his neighbors about stormwater management and renovating a one-mile stretch of the city. Once it received support from a local alderman, Simon’s idea quickly grew into what is now the 3 1/2-mile-long Milwaukee Green Corridor. City officials, business owners, and the community at large are using the initiative to showcase design ideas and products that conserve energy and water, reduce runoff, and otherwise enhance livability. The market plaza itself is a showcase of sustainability and an agent of change. Along with the social and local-business improvements that a dedicated farmers market provides, the materials and methods used to craft the space were specifically chosen for their conservation attributes. Aesthetically, Simon went beyond creating a flat gathering space, instead making the surface underfoot an integral part of the experience. The layout for the 66 10-foot-by10-foot vendor booths and pedestrian aisles was created using varied patterns and colors of pavers, sustainably manufactured by CalStar

Products in nearby Racine, WI. To create the individual stalls, Simon and his crew installed CalStar’s autumn-colored Holland pavers in a basketweave pattern bordered with dark-gray pavers. The 8-foot-wide aisles feature tumbled, natural-colored pavers laid in a herringbone pattern. Another dark-gray border outlines the entire perimeter. The design offers clear delineation of vendor spaces on market days while providing visual interest to the vast space when not in use. “Paver orientation was an ideal way to make our farmers market unique and attract vendors and people,” said Simon. In keeping with the Green Corridor’s sustainability mission, the pavers are manufactured using a process that incorporates 40% recycled material, emits 85% less CO2, and uses as much as 85% less energy than conventional pavers. Using the 64,935 CalStar pavers, rather than traditional concrete pavers, prevented almost 25 tons of CO2 from being emitted, saved 32.5-million BTUs, and diverted 69 tons of waste from a landfill. As an example, the CO2 avoidance alone is equivalent to removing more than four cars from the road for one year. Adjacent to the Farmers Market, a community garden is slated to include a park with an amphitheater, pergola-covered seating areas, and an interactive water feature circulating captured rainwater. Completing the block-long space are growing areas where citizens can rent in-ground plots and raised

beds. CalStar permeable pavers will provide paths that connect the green areas.
Widespread adoption Sustainable projects such as these are appearing all along the Corridor, the development of which is now led by a steering committee that includes Simon, government officials, city departments, nonprofits such as American Rivers, and The Gateway to Milwaukee, a local business association/business improvement district. Among the new projects are bioswales, a strategy the city is employing as an alternative to traditional storm drains. Businesses have joined the effort, including one that installed a green roof and another that now captures 100% of the water that falls onto its property. Benches and pocket parks are planned, and Community Design Solutions, a student organization at the Univ. of Milwaukee, is helping with project planning and design. “We see this as a good thing,” said Jim Tarantino, director of planning and operations for The Gateway to Milwaukee. “It infuses new energy into this once distressed area, and it is a good location for the city to try new things.” “Watching the Corridor come to life has been inspiring,” Simon said. “It’s a true testament to what can happen when vision, teamwork, and community spirit come together.”

he third-oldest general hospital in the United States, Massachusetts General (MGH) is known for its world-class patient care. Located in the heart of Boston, MGH is planning for its next century of service to the community and focusing on a facility that performs efficiently while promoting the health of the 1.4 million patients treated annually and the staff who care for them. Plans for expansion began in 2005 with architects from NBBJ New York leading the design effort. Approximately 170,000 sq. ft. of outdated hospital buildings on the campus were demolished to make way for a new facility called the Lunder Building, also known as the Building for the Third Century. A high-tech, progressive, flexible structure, the Lunder Building houses a 150-bed tower, as well as new emergency and oncology units within its 535,000 sq. ft. Research indicates that healthcare facilities designed with nature and the environment in mind reduce the length of patient stay. Designers used that as a key concept of the design vision, which included the notion of bringing nature inside.
Get free product information at www.cbpmagazine.com
Eco-healthy solutions In support of its sustainable-design principles, a third of the Lunder Building’s construction materials are either recycled or locally procured. To reduce energy use, a special glazing system on the windows cuts heating and cooling costs by more than 30%. The rooftop gardens provide natural insulation and trap rainwater, which is used to water plants. From rooftop to underground floors, the design team aimed to provide people with access to gardens, as well as patterns and colors inspired by nature that visually connect the space. Every patient room has a direct view of nature, either by facing rooftop gardens or the six-story atrium. The intensive-care unit overlooks bamboo gardens, creating a tranquil atmosphere for patients, families, and hospital staff. For a project focused on the use of renewable materials, eco-friendly construction methods, and energy reduction, Skyline Design, Chicago, was well-suited to provide interior-glass solutions. As a producer of sustainable decorative glass, Skyline strives to make environments more beautiful and efficient in the smallest carbon footprint
project INTERIORS possible. Made from natural elements—sand and minerals—eco-friendly glass is easy to clean and recycle, making it a natural choice for MGH. Always mindful of the environment, the company selects and sources materials locally, taking into consideration their environmental impact, recyclability, and reusability. Design and manufacturing efforts focus on creating a spectrum of sustainable, handcrafted, quality glass and architectural products customized to suit clients’ needs and avoid waste. Customers can choose from a number of progressive and earth-friendly techniques—etching, texture, printing, and painting on glass—that use lowVOC paints and finishes.
Urban forest Using hues and patterns developed by the NBBJ design team, Skyline helped transform the Lunder Building by bringing nature indoors, creating a soothing, healing environment. Two distinct yet related graphic themes were used to aid in wayfinding and create a positive experience for patients, families, and staff. The garden theme, which is applied in the building’s lower levels, evokes the sense of calm and tranquility one might experience in nature. Moving upward in the building, a tree-canopy theme reflects Boston’s streetscape. Because the urban forest plays an important role in Boston’s landscape, designers worked with the city’s parks-and-recreation department to choose particular species for the tree-canopy theme. Different trees—crabapple, mountain ash, pin oak, dogwood, and silver maple—are featured on each of the building’s five levels to provide wayfinding cues throughout the facility. Color complements the graphics accordingly, with soft tones—symbolizing the restoration of health and wellbeing—used in the garden spaces, and bold color applied where people would seek human interaction. One of the building’s most prominent features is a six-story garden atrium with hanging plants. The atrium is framed by floor-to-ceiling walls of Skyline’s Sateen glass, a translucent tactile pattern from the Weaves + Textures collection. Made using the Eco-etch technique, a proprietary process that uses recycled aluminum oxide to provide a fine, consistent finish, the Sateen pattern is etched on one side to let in natural light while offering privacy to patients and families. With the etching on the outside, Sateen enables MGH to maintain its stringent healthcare cleanliness standards.
Underground garden In the radiation oncology waiting area, a soothing garden pattern is showcased as full-length wall art. Using NBBJ’s original graphic—an abstraction of trees from an upper-level floor—
Skyline replicated the artwork by applying the Eco-etch process on one side and printing on the other side with its AST technique. With its color capabilities, AST prints dynamic graphics that provide opaque and translucent effects. The Vitracolor backpainting technique added color and integrates with the finishes chosen by the design team. Using water or low-VOC paint, the technique offers an extensive color selection, exact color matching, and a uniform coating process for even application. Made of nine panels, each 3-feet, 6-inches wide by 6-feet, 6-inches high, the artwork integrates the garden theme in a part of the facility that’s four floors below ground level. “Since we couldn’t bring daylight underground, we tried to create stylized garden spaces that provide a spa-like atmosphere for radiationoncology patients and their families,” said Celeste Robinette, branding and design associate at NBBJ, Seattle. “The artwork helps create a calm, healing environment.” Along with the light, airy ceiling, the space is uplifting—just what patients, family members, and staff need. “Skyline would get on the phone to discuss processes with us, then play with the effects to get the ones we wanted,” said Robinette. “They helped us make sure we got the colors the way we wanted them, especially in the waiting area, where we used neutrals. If the colors weren’t right, that space would have looked totally different.” In the emergency department, floor-toceiling glass panels add softness and warmth with a custom floral-garden pattern on one side and a custom gradient-dot pattern, applied with Skyline’s Eco-etch process, on the other. Chosen for its ability to create a sense of privacy, the translucency of the dot pattern instills tranquility for patients while giving staff the visibility they need.

Form, function, and LEED Completed in 2011, the Lunder Building has achieved LEED-NC Gold certification. It also won an AIA NY Design Award 2012 and the Design & Health World Congress Highly Commended Award 2011. It’s a unique, efficient, and comfortable hospital facility that will improve not only the patient and family experience, but also the day-to-day experience of the people who work there. Using simple, clean, earth-friendly glass, Skyline provided several natural and healthy solutions that alter light to transform space and bring nature indoors. Practical and easy to maintain, glass is a smart choice in healthcare environments.

project INTERIORS Renovation at the Osawatomie, KS, public library includes a machine-room-less elevator.
Going Up With Renovation A machineroom-less elevator provides access, safety, and additional space.
F
itting today’s technological advancements seamlessly into an old building’s architecture is a challenge faced by many architects and building owners looking to renovate. Creating more space is also a goal for many projects. Renovation of a Kansas public library resulted in doubling the usable space of the existing building with the installation of an elevator. Patrons of the library in Osawatomie, KS, had long been limited in use to only 3,600 sq. ft. on its upper level. An old, unsafe staircase made the lower level inaccessible. As a result, only half of the library’s 18,000 volumes were available. Making use of the entire space for the library’s book collection and creating accessible, ADA-compliant, usable space to showcase valuable local historical records, including Civil War genealogies, was of utmost importance. Library and local officials determined that an elevator would provide safe access to all building levels.
Choosing an elevator Increasing the usable library space was top priority. Maintaining a tranquil environment also was essential, so an elevator had to be noticeably quiet. Of course, the elevator had 38

to meet high standards for safety and reliability. Like most small towns, Osawatomie had a limited budget for installation and upkeep for the elevator, which led to consideration of cost-effective options that would be energyefficient and provide full-service, reliable maintenance. A machine-room-less elevator proved an ideal solution. The model 3300 elevator from Schindler Elevator Corp., Morristown, NJ, requires no machine room or control closet, and allowed the library’s architect to carve a new electrical room from the unused space. The elevator’s STM suspension traction media makes room for the machine and drive directly in the elevator hoistway, allowing hydraulic-sized shafts to be used. With the newfound space, the renovation was able to include a children’s department on the lower level. According to Elizabeth Trigg, library director, “Not only did the Schindler 3300 elevator conserve space for us, it actually doubled our usable area to 7,200 square feet by making our lower level accessible to everyone.”

reading room, the elevator offers a range of safety features. The unit is equipped with the company’s SRM remote monitoring, a proactive maintenance tool that monitors the system 24/7 and helps return equipment to service as much as 22% faster than traditional troubleshooting methods. Automatic evacuation is a standard feature. In the event of a power failure, the elevator automatically returns to the ground floor to release any passengers. The cutting-edge safety features gave rise to superstition among library staff following the first power outage. Trigg explained, “For a while, we wondered if the elevator might be haunted. One day, we had a storm with a power failure, and the elevator automatically returned to the lower level. We heard voices coming from the elevator, but upon inspection found no one inside and no one on the lower level. We later learned that when there is a power failure, the local Schindler service office is notified through remote monitoring, and they call the elevator to see if anyone is inside. The ghost story was kind of fun while it lasted, though.”
Custom-finishing options allow the elevator to fit the library’s renovated look.
A Schindler 3300 elevator connects the lower children’s department with the main-level library.
Sustainable solution The elevator provides a sustainable, cost-effective solution for library staff and patrons. Along
with a range of customized design options to marry the historical and contemporary aspects of the project, the gearless machine saves energy. The elevator is equipped with a frequency converter and door drive that operate in standbypower mode to reduce electricity use. Car lighting includes controls that automatically switch lights to standby mode when the car is inactive. All fixture lighting is low-power LED. A central guiding system reduces friction and overall energy consumption. The addition of the elevator not only transformed the library space but also allowed development of new library programs for young patrons while housing the history of the town’s oldest residents. “We are very pleased with the elevator and the increased usage of space it has allowed us. We appreciate the clean lines and the energy efficiency of the elevator as well as the overall quietness when it is running. We are quite pleased with the product and very happy to have a working elevator in our library,” concluded Trigg.

ngineers at multi-discipline engineering firm William Tao & Associates Inc. (WTA), St. Louis, liked the performance and aesthetics of fabric HVAC air-distribution ductwork enough to replace an otherwise adequate spiral-metal duct system with fabric while renovating its office headquarters. WTA recently moved into the 17,000-sq.-ft., top-floor space of a two-story, freestanding office building in the St. Louis suburb of Maplewood. Bruce Levitt, P.E., LEED AP, WTA’s executive vice president, was the lead engineer on the former call center’s remodeling and Leadership in Energy and Environmental Design effort. Levitt didn’t like the aesthetics of the existing metal duct or its low-hanging, 10-foot-high diffuser drops. He preferred a more streamlined alternative: fabricduct air dispersion that would add aesthetics as well as contribute to LEED credits. However, WTA president Richard Janis, P.E., AIA, LEED AP, didn’t like the reputed deflated appearance of fabric duct during air-handler inactivity. The two engineers found a conciliatory resolution in SkeleCore, an in-duct cylindrical tensioning device (CTD) from fabric-duct manufacturer DuctSox, Peosta, IA. CTDs promote a perpetually inflated appearance and eliminate roll-out popping sounds when air-handling equipment starts up. The SkeleCore CTD system consists of a lightweight, 3/4-inch-diameter aluminum tube that runs down the middle of a duct to support

a series of 3/16-inch, powder-coated-steel connecting rings. The 360-degree rings are sized precisely to administer tension on the fabric-duct walls for a permanently inflated, streamlined appearance.
Upgrading without replacing After dismantling the metal duct, a crew from Rock Hill Mechanical, St. Louis, took less than a week to install 475 linear feet of DuctSox’s Sedona-Xm fabric duct with SkeleCore, according to Mike Sullivan, the mechanical-contractor’s service manager. Sedona-Xm is 55% recyclable, which helped accumulate project credits for a target LEED certification of Platinum by the U.S. Green Building Council, Washington. Fabric duct also contributed to LEED credits by: • improving indoor air quality • reducing material waste from less packaging • producing less jobsite waste because the custom product requires no on-site trimming or cutting • reducing energy consumption during shipping, because the lightweight fabric was shipped from within 500 miles • eliminating off-gassing associated with metalduct paint and coatings • improving efficiency with a 24.5% gain over conventional metal-duct systems, according to a computational fluid-dynamics energy study performed by the mechanical-engineering department at Iowa State Univ., Ames.
project HVAC To increase indoor air quality without sacrificing static pressure, the engineers decided to keep seven existing rooftop HVAC units and update them with filters that had higher MERV (minimum efficiency reporting value) ratings. The rooftop units and their retained sheet-metal drops supply 15 runs of 10-inch-diameter fabric duct hung from an architectural track-suspension system. To complete the airflow system’s aesthetics, Levitt chose a tan color to complement the other earth tones of the new interior’s floor coverings, furniture, and surface painting.
One reason the engineers specified fabric ducts was its lack of dropped diffusers like the one shown in the inset. The result is a cleaner look and more even temperature control in the space.
Specifying fabric duct Assisting Levitt in the fabric-duct specification was Pat Olwig, product sales manager at Langendorf Supply, Bridgeton, MO, a manufacturer’s representative firm specializing in ventilation. With the new system, air is dispersed partially through the fabric duct’s factory-engineered ComfortFlow porosity, while the remainder is distributed evenly through a system of linear orifices (7 cfm/ orifice) that appear at the 3:00 and 9:00 positions the entire length of each run. “Although the metal and fabric were hung at the same 12-foot height, the metal had 2-footlong diffuser drops to 10-feet-high, which was unappealing,” said Levitt, who has specified fabric duct for more than 20 projects. “Now the air distribution is higher for better sight lines, but without sacrificing occupant air comfort.” The original metal ductwork dropping from the rooftop system was retained and painted the same tan fabric-duct color, which matches the interior design retrofit. To eliminate excess heat generated by conventional lighting, Levitt also added energyefficient lighting innovations including LEDs and motion sensors. Instead of traditional halogen sources, the space uses a variety of direct and remote-phosphor LEDs in downlight products. Energy Saver LED, St. Louis, provided retrofit integral-driver LED PAR lamps. Cozad Property Management Co., St. Louis, the property’s management firm that oversees more than 2 million sq. ft. of local industrial, commercial, and residential space, was pleased with the outcome of WTA’s professional architectural and engineering work for the building. “The space is noticeably quieter and I think it’s due to the interiors and the fabric-ductwork updates,” said Don Kelly, construction manager for Cozad. Echoing Kelly’s comments, Levitt said, “The fabric duct is quiet and the in-duct tensioning system gives it a great appearance that everyone is very satisfied with.”

S
an Francisco’s Golden Gate Bridge is acclaimed as one of the world’s most beautiful bridges. With its tremendous towers, sweeping main cables, and great span, it is a sensory beauty featuring color, sound, and light. Celebrating its 75th anniversary this year, the bridge can be a very busy place. It is estimated approximately 9 million people from around the world visit the bridge every year. Construction of the 3,426-sq.-ft. Golden Gate Bridge Pavilion was a key part of the anniversary celebration. Nichiha USA Inc., Norcross, GA, supplied its Illumination series fiber-cement panels for the pavilion’s exterior. The panels provide a moisture-management system and also call attention to the structure itself, with the famous international-orange color on three sides and a fourth storefront wall of floor-to-ceiling glass. The panels’ physical properties were a determining factor for their incorporation into the pavilion. Durability, panel proportions, clipping system, texture/finish, V-groove panel joints, and the ability to use the company’s Color Xpressions system to match any paint manufacturer’s color in satin finish aided in the decision. The company’s patented clip system allows panel joints to fall off stud locations. “When you have a landmark with such strong national recognition and commitment,

you know you have the right combination of product advantages,” said Doug Kennard, territory manager at Nichiha. “This Golden Gate Bridge Pavilion project typifies all the aspects of the Nichiha brand—providing quality exteriorcladding solutions that deliver high performance and bring to life the look our clients desire. If we can also lower the installed cost and shorten the installation process, we’ve done our job.” The pavilion itself is constructed from environmentally responsible materials and has many green features including highperformance, super-insulating glass units with suspended-film technology; abundant natural daylight; an ultra-high-efficiency furnace with an economizer function; and low-flow plumbing fixtures, in addition to Nichiha’s sustainable panels that contain 40% recycled content. Providing historical-information displays for visitors, the pavilion includes interpretivedisplay elements and artifacts and also provides educational information about its sustainablebuilding techniques, energy performance, and environmental responsibility.

Renovate! The Soldiers & Sailors Memorial Hall and Museum is a Pittsburgh landmark.
Fixed vinyl windows with low-e glass protect the museum’s historical stained-glass windows.
S
oldiers & Sailors Memorial Hall and Museum is a Pittsburgh History and Landmarks Foundation site and is listed in the National Register of Historic Places. Designed by architect Henry Hornbostel to create a memorial in honor of Allegheny County men who fought in the Civil War, the museum was completed in 1910. Over the years, it has grown in scope and purpose, honoring each generation of service members from each branch of service, serving in every U.S. conflict and in peacetime. Today, it is the largest memorial in the nation dedicated solely to honoring all branches of military veterans and civilian service personnel. In January 2000, a trust was created to repair, improve, maintain, operate, and generate operating income for the museum. During the past 12 years, the museum has undergone major repairs and improvements, including several recent projects directed at energy conservation. One of the projects was replacement of the single-pane wood windows on the first level. The glass had been replaced at least once in the history of the building, but most likely that occurred at least 50 years ago. Building managers, concerned about sustainability interests and rising energy costs in Pittsburgh’s four-season climate, initiated an energy-conservation plan.
First things first The Memorial consists of two major levels, but the windows and doors on the first floor were
Windows Brighten Museum Replacement windows provide energy efficiency with a historical look. identified as energy eaters and negatively affecting the building’s overall energy efficiency. After researching their options, managers chose vinyl Tilt/Turn windows from Ventana USA, Export, PA, for the windows’ convenient function, energy efficiency, and potential to match the historical characteristics of the existing windows, inside and out. The windows, part of the Euroview 70DS system from Veka Inc., Fombell, PA, have a 2 3/4inch frame depth. Their thermal properties are the result of a five-chamber air-pocket system used in all frames and sashes. Frame and sash profiles are steel-reinforced to provide structural strength and decrease the thermal expansion factors inherent in a PVC system. Installed by Bruce Construction, Plum, PA, the windows’ dual-function advantages easily met the project requirements. The concretewindow-façade frames block access from the
exterior, preventing cleaning the windows from the outside. The inswing-turn feature of the Tilt/Turn window solved this problem, while the tilt function provides ventilation. The lamination capabilities of the vinyl system allowed the replacement units to match original interior wood trim. The color Nussbaum (a deep brown) was chosen for the halls, while golden oak was used in the lobby. A fixed mullion was added to the sash to emulate the original divided mull casements. Another problem came from five large, stained-glass, circle-top windows that were leaking badly. To protect these historical windows, Ventana fabricated fixed vinyl windows with low-e glass to match the outside openings, keeping the stained glass visible while protecting it from further deterioration. Since replacing the windows, Soldiers & Sailors has begun to see lower energy costs. Additional benefits include sound abatement and reduced UV damage to the thousands of artifacts on display in the exhibits located on the first level, which are often lit by the natural light entering the building. This magnificent structure is now ready for the next 100 years.

he Schwab Center for Information Technology
at Norwalk Community College, Norwalk, CT, is a far cry from IT spaces that look as if they evolved with little or no design direction. The emphasis here is on the people who communicate, not on computers. The arches over the central hall comprise stylized human forms. The walls below feature sculptures of contributors to the development of the computer. Architects and designers: Svigals + Partners LLP, New Haven, CT. Arch fabrication/installation: Breakfast Woodworks, Guilford, CT. Designers/ sculptors: Barry Svigals, FAIA (Svigals + Partners) and Randall Hoyt (Randall Hoyt Design, Coventry, CT).
