Light streaming in through floor-to-ceiling windows, massive lightwells, and daylighting controls— natural lighting is one of the first things today’s architects and designers consider when setting out to create inspiring spaces. We see natural light everywhere in the March/ April issue of gb&d magazine, from our cover story on hospitals to the public spaces we feature in Typology (page 26). Great design always finds ways to work with nature, and hospitals like UCSF Medical Center at Mission Bay in our cover feature, “How to Build a Healthy Hospital” on page 56, are a great example. There, the commitment to health and healing goes beyond medicine, with more than four acres of gardens, as well as balconies where patients can step outside and breathe in the fresh air. But light and nature also have a positive impact on learning, and the design team behind the new Langara Science & Technology Building on the campus of Langara College in Vancouver knew that all too well. This five-story project from Proscenium Architecture + Interiors Inc and Teeple Architects is filled with light and views of the great outdoors— students will find views in more than 90% of regularly occupied areas here, in fact. Like principal Kori Chan says, “Natural light promotes a healthy environment. People feel better when there is natural daylight.” Daylighting also played a big role in this issue’s “Defined Design” on page 16, where a new, Prairie School–style Iowa medical center by HGA Architects
and Engineers combines many windows with splashes of blue stained glass for a bright, cheerful feel you might not be used to getting when you go for a medical checkup. Add to that walking paths and patios, and you might not feel so bad after all. Of course, incorporating nature and daylight into design isn’t just good for the psyche. Architects and building owners know it also makes a lot of sense for their bottom dollar as well as for the environment, reducing electricity usage and saving energy along the way. And with designs like the ones you’ll see across these pages, who wouldn’t be inspired to do more of the same?

Sustainability is often found through great leadership, with the people at the top of their fields doing what makes the most sense for their company or organization. You’ll find examples of strong leaders across the pages of this issue of gb&d magazine, all of them making great strides toward efficiency in what they do and what they provide for others. Take, for example, the Steel Market Development Institute (SMDI) on page 50. This business unit of the American Iron and Steel Institute (AISI) in Pittsburgh is committed to educating people about steel. They’re also developing EPDs, or Environmental Product Declarations, so architects and designers can make informed decisions and have a better understanding of potential environmental impacts of construction products. Businesses need speed and efficiency. Efficiency helps drive business, whether that’s saving time and energy in the bath-
room of Brooklyn Bowl with Excel Dryer’s XLERATOR (page 40), building quickly yearround with Fabcon (44), or installing large Entrematic HVLS fans (page 18) to reduce air conditioning and increase air flow in places like gyms and restaurants. Then there’s AWIP (All Weather Insulated Panels), another example of a company that continues to look at how it can prevent unnecessary energy loss. AWIP (page 22) knows having a properly insulated building means saving energy, and buildings with insulated metal panels can reduce energy cost by two-thirds. Consumers are increasingly savvy, too, with a growing desire for sustainability and accountability. Like Brooklyn Bowl developer-owners Peter Shapiro and Charley Ryan said in their interview, their clientele can see past a fancy LEED plaque on a wall to question not just how a facility is built, but also how it operates. The more people are educated and curious about sustainability and efficiency, the more they want and need out of their buildings and solutions. Building owners, and therefore manufacturers, realize this and need to use and manufacture optimum products for efficiency, air flow, energy consumption, and so on. This issue is full of stories about those in the green industry who continue to make efforts toward achieving true sustainability, never saying what’s done is good enough. Instead, they ask, “What’s next?”

In Conversation Bruno Sarda
How you buy your power matters, according to this leader in energy and advocate for a sustainable future. By Brian Barth Bruno Sarda, the vice president of sustainability at NRG Energy, says there is good reason that the renewable energy revolution makes some people a little nervous. “Change is hard,” he says. “Especially very big disruptive change. But it’s also very exciting.” Sarda likens sustainability to the internet of the ’90s. Everyone knew it was the way of the future, but figuring out what to do about it in the present was often nerve-racking. The good news is the sustainable energy future that visionaries were dreaming about just 10 years ago has largely arrived. Some of the worst growth pains are behind us, says Sarda. No longer just a shimmering idea about how to power the planet without polluting it, wind, solar, and other renewable technologies are becoming the new backbone of the nation’s electric grid. In 2015, 64% of the new electricity generating capacity in the U.S. came from renewable energy sources, according to the Environmental and Energy Study Institute. Virtually no new coalpowered production has come online in recent years, giving some hope that the goals of the Paris Agreement can still be met. NRG, the largest independent power provider in the country, is at the forefront of that trend. NRG is third in the country in terms of renewable energy generation and reduced its carbon emissions by 40% from 2005 to 2014. They aim to reduce emissions another 50% by 2030 and 90% by 2050 over the 2014 benchmark. Sarda joined the company in 2016 to oversee the journey toward those ambitious goals after a stint as the head of sustainability at Dell. He also helped to develop the Executive Master of Sustainability Leadership at Arizona State University, where he continues to teach part-time. He recently sat down with gb&d to discuss this exciting time in the energy sector, as well as his personal philosophy on bringing up the next generation of sustainability leaders. gb&d
IN CONVERSATION with Bruno Sarda
gb&d: What first turned you on to the environment and the idea of sustainability? Sarda: I got interested in sustainability pretty early. I grew up in France and there wasn’t a lot on TV back then, but one of the things I loved to watch was Jacques Cousteau. I was really inspired by his approach to ocean conservation. It definitely made me aware that our actions as people matter—and that if we’re not careful we can drive both species and ecosystems to the brink of extinction. gb&d: What about his approach sticks with you today? Sarda: What has stuck with me all along is, unlike many others in the field, he wasn’t necessarily telling people, “You’re bad for doing these things,” but rather he invested himself as an inventor, as an explorer, and as a storyteller to really make us fall in love with the underwater world and its creatures. People protect what they love, right? So rather than try to shame us or scare us, it’s like, “Look, this is awesome, why not protect it?” It’s become part of my own philosophy.
“Let’s do all these things because what will happen as a result is great—as opposed to doing it to avoid outcomes we fear.” I approach sustainability very much from an opportunity, rather than a fear-based, approach. It’s like, let’s do all these things because what will happen as a result is great—as opposed to doing it to avoid outcomes we fear.

I went to work for Charles Schwab in the mid-90s we were trying to figure out what the internet was and what it was going to mean to both the business itself and to the individual investing space.
By Ayrie Gomez
gb&d: How did you make the leap to sustainability? Sarda: Well, working in IT in the early years taught me a couple of things. One, that change is hard. Especially very big disruptive change. The internet was massively disruptive to both organizations and their customer base. It’s not like anybody sat around saying, “Oh this internet thing, I don’t want it.” It was just hard. But it was also exciting. It engineered and engendered so much creativity and innovation. Today it’s hard for us to imagine what our daily lives would be if we didn’t have all these internet-powered devices supporting us. For me, sustainability is a lot like that. Sustainability is this big disruptive societal force that is making us rethink how we do everything as organizations, as individuals, as a society. Again, it’s a good change, but it’s a hard change. Ultimately what I realized is helping organizations and people move through the disruptive change was something I had become good at, and so that’s how I got here. gb&d: What is your role at NRG today?

Sarda: We have a few core businesses. One is wholesale power generation. We own a bunch of power plants where we produce electricity and sell it to the grid. So a big part of my job has to do with looking at how that power is produced and specifically the water- and carbon-intensity of the process. We also work directly with large power users on their own power solutions, whether it is deploying on-site renewables, off-site renewables, as well as energy management solutions. Collectively my job is about understanding how sustainability factors into the overall strategy of the company. I work with every part of the business to shape and form and influence the way we do business so that it helps us meet or exceed our sustainability goals. gb&d: What are some examples of your current sustainability initiatives?

When HGA Architects and Engineers was tasked with making a large medical facility feel intimate and personal, they focused on two things— repetition and nature.
The center also had to fit into the Prairie-style aesthetic around it. “We studied Prairie School architecture in depth and realized that a three-story, 90,000-square-
foot Prairie-style inspired building would be a challenge,” says HGA’s Donovan Nelson, the architectural design lead. “The success of marrying the Prairie-style aesthetic with the size of the building would come down to one thing: scale.” Flanking the three entry vestibules at UnityPoint Health - Prairie Parkway are blue glass panels, echoing the stained glass patterns of Prairie-style architecture. The motif carries through to the stairs, waiting rooms, and staff spaces. The design of the $30 million multi-specialty campus—with services ranging from ob-gyn, pediatrics, and family medicine to

Daylighting Using windows or other openings to allow natural light to provide internal lighting, maximizing visual comfort and reducing energy use.
Medical home model This facility is designed as a medical home model, where multi-specialty providers come together with the patient to look at a comprehensive care plan, rather than multiple providers each in their own clinics presenting plans to the patient. The medical home is patient-centered, comprehensive, team-based, and focused on quality and safety.
plants to be gas-powered, reducing the collective carbon intensity of those plants by a very significant amount. But there are all kinds of other things. We are starting to work a lot more with our supply chain because it is not just about our own carbon footprint, it’s about who we buy stuff from, as well as our office space. So it’s a lot of people-centric and place-centric sustainability initiatives, whether it’s waste reduction or composting or the energy efficiency of our own offices. We are also working quite a bit with the customer side of things. Because ultimately the collective carbon footprint of our customers is much larger than our own. We make sure that we help them have a better understanding of their energy solutions and their energy management strategy, both to reduce the environmental footprint of their organization and, in most cases, to help them save a good amount of money. gb&d: How active is NRG with wind and solar? Sarda: We have a very large portfolio. We’re one of the top developers and upgraders of large-scale solar. We are one of the top in wind. A lot of our new development is in the renewable space. We’re building a lot of community solar now as well—it’s not utility scale, but community scale. gb&d: How do you define the concept of the smart grid?
says HGA’s Christine Guzzo Vickery, interior design lead. The Cedar Rapids, Iowa, facility proves it can be done, starting with floor-to-ceiling windows in public areas so light streams in. The natural light and reflections of the blue glass bounce around in the space to create a whimsical feel. To save energy, daylighting controls automatically dim electric lighting when enough natural light is available. gb&d
Then there’s the proximity to nature, also helped by the windows. “We made sure that no matter visitor or staff, there is always a connection to the landscape,” Nelson says, adding that floor-to-ceiling windows also make up the back of house spaces. “These windows bring light in and invite views out to the surrounding natural landscape.” Walking paths and patio spaces abound, too.
HGA also incorporated green features like low-VOC paint, low-VOC adhesive, and reduced formaldehyde in its design and used local materials like local stone for the fireplace and Iowa walnut for the interior. “The movement today is towards inspiring wellness, not simply designing a place for sick people,” Vickery says. StruXture Architects also worked on this project.
Sarda: It’s one of those things like Big Data—sometimes people use that term loosely. But the idea of the smart grid is to put systems intelligence into the way power is produced, distributed, and consumed. A good example is what we are doing with demand response. This means, if we have the right technology in place, we can help our large power customers shift the time of day that they use a lot of power to a time when power is least expensive. This way they avoid demand charges, which can be very costly. You can’t really do that without having good information systems in place. gb&d: What’s the sustainability component of that picture? Sarda: Ultimately we see these information-driven systems playing a big role in integrating more and more renewables and battery storage into the grid. To be able to do that you have to have a very detailed understanding of load and generation. With This conversation continues on p. 77

Quiet Comfort with Entrematic’s HVLS Fans By Laura Rote Richard Hoofard sits in a large office lobby, chatting on the phone, glancing up at the large, quiet fan overhead. He’d almost forgotten it was even there, which is funny because, as the director of engineering for Entrematic, the company who made it, he knows precisely how it works. “The thing about these fans is they’re very silent. Under normal operating you cannot hear them,” Hoofard says. Hoofard works for Entrematic, the maker of the line of commercial HVLS (high-volume low-speed) fans you see more and more in restaurants, bars, office buildings, and even churches. If you notice the fans, at all, that is. They’re often designed to fit seamlessly into their surroundings, though they can be designed to fit in or stand out as much as you’d like, whether you want an all chrome or rustic wood style, among others. gbdmagazine.com

Since they’re virtually silent, you’ll also find Entrematic’s fans in locales like the Corsicana Opera House just south of Dallas as well as in churches and schools. you bake,” Hoofard says. “You don’t want to be able to hear the fans in schools, especially during test times,” Hoofard Most offices also have just a says. “Sound is a huge issue, and we designed this to be silent.” couple of air conditioning vents You can find Entrematic’s fans anywhere from your standard office environment— per room, so a lot of air has to be like a lobby or large call center with rows upon rows of cubicles—to restaurants or more forced from just two places. “The industrial areas like auto shops.

improve the efficiency of the air conditioning system, reduce energy, and improve comfort. Most people like a little bit of airflow—no one likes stagnant air. What we do is provide the ability to generate that gentle airflow in large volumes.” Looking up at the very fan that was spinning above him recently, Hoofard remarks on its efficiency. “Looking at the one in my lobby now, it’s turning at about 25% [of full power]. That’s all it requires.” The fans work easily with other technology, as Entrematic fans can be networked into an overall building management system, EMS or DDC. This allows business owners to automate the speed of the fans, turn them off and on, or change the fan’s direction. It also eliminates your coworkers from fighting over the thermostat.
THREE DEGREES If the fan is in the right place, you can increase your thermostat temperature by approximately three degrees, Hoofard says. In
HVLS fans have larger blade sets than typical fans, and they move air more calmly compared to a fan that has to blow a narrowly focused, high volume stream of air or an air conditioner that blows coldly to a small area. “No one ever wants to sit under an air conditioning vent,” Hoofard says.
a harsh environment like Texas, that adds up to a lot of money saved over time. “From an energy use perspective, that’s huge,” he says. Entrematic used a comfort level generator, developed by ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) to calculate its fan’s design. “We developed our design to work within the office environment and to be optimal for efficiency and comfort,” Hoofard says.
DID YOU KNOW? HVLS fans were originally designed to cool livestock—hot cows don’t often produce the same amount of milk. And cows, like people, also don’t love strong breezes. The solution? The HVLS fan.
IN DEMAND As more and more people are learning about HVLS fans, demand increases. “HVLS fans didn’t exist before the year 2000. They’re a relatively recent invention,” Hoofard says, adding that they actually came about as a way to cool livestock in large dairy barns. Hoofard says HVLS technology was originally geared toward the industrial side—in large warehouse environments, for example. Over time, that migrated to “Hey, what about moving them into the commercial side?” Enter Entrematic fans in big stores like Costco, restaurants, bars, churches, schools, and now offices. Some people even see the fans in offices and decide they want one for their house, especially those with large houses and vaulted ceilings. “We’re seeing some residential demand, not nearly what we’re seeing on the commercial side, but to me it’s a logical progression,” Hoofard says. HVLS fans have come a long way since the beginning, and Entrematic’s risen to the top of the list. Pope has been in the construction industry for about 15 years and has seen similar companies—those who sell at big-box retailers—but says they aren’t as aesthetically pleasing as Entrematic’s. “They just didn’t look like what we wanted them to look like.” Entrematic fans can be designed to look any way you want to match any environment. They also come in an array of colors, whether you want “starburst silver,” cobalt blue, “red baron,” or any other color. The choices are literally endless. The Telos team settled on two sleek, silver fans, installed in August 2016, and Pope says he couldn’t be more pleased. “We never have a shortage of cool air blowing now.” gb&d gbdmagazine.com

ALL WEATHER INSULATED PANELS INSULATED METAL PANELS ENERGY-SAVING EASY TO INSTALL ELIMINATES ROT & MOLD MEETS NET ZERO GOALS PAYS FOR ITSELF
A Better Way to Build When HALDRUP GmbH, a Germany-based farm equipment manufacturer, broke into the North American market, they had just one requirement: their new plant should be constructed of insulated metal panels (IMPs). IMPs, like the ones All Weather Insulated Panels (AWIP) provided for the new plant, are a staple in European construction, where they are beloved for their economical value, easy assembly, and fantastic insulation properties that keep energy loss (and costs) low. “Metal panels make it possible to get the building operational quickly,” says Rüdiger Hofmann, owner and civil engineer at HALDRUP. The speedy assembly of these insulated metal panels ended up saving HALDRUP from falling behind schedule when frozen ground prevented them from digging the building’s foundation. The panels require far less specialized equipment to install and, due to their self-aligning, tongue-in-groove joints with concealed fasteners, they are a snap to fit together. The streamlined construction meant the project could be completed on time, even with the setback. Hofmann also insisted on the IMPs for environmental reasons—their high-performing energy efficiency is another reason they are widely used in Europe, where energy costs are generally higher.

THIS SPREAD All Weather Insulated Panels save time and money as they require less specialized equipment to install and are a snap to fit together.
GREEN GLOSSARY CALIFORNIA PUBLIC UTILITIES COMMISSION Controls public utilities in California. Issued an aspirational goal in 2008 that all new residential construction would be Zero Net Energy by 2020 and that all commercial construction would be ZNE by 2030.
HONEYWELL SOLSTICE® LIQUID BLOWING AGENT Honeywell’s new liquid blowing agent, based on hydrofluoroolefin (HFO) technology, provides closed-cell foam with many of its performance characteristics. It creates superior insulation for commercial and residential use.

AWIP’s products protect against energy loss with a tightly sealed building envelope that keep outside weather, whether humid or dry, from interfering with the interior climate. And they are now even more efficient thanks to the addition of Honeywell’s Solstice® Liquid Blowing Agent (LBA). The new product fills even the tiniest gaps in the already drum-tight composite with hydrofluoroolefin technology–enabled closed-cell foam, preventing the loss of hot and cold air from buildings. Honeywell and AWIP are the first to introduce this blowing agent technology for insulated metal panels to North America.
INTERIOR CLIMATE CONTROL WITH MINIMUM ENERGY USE Having a properly insulated building means saving energy. It’s no secret in the industry that the second largest contributor to greenhouse gases is the energy used inside buildings. The founder of AWIP, William Lowery, says a building with insulated metal panels can reduce energy cost by two-thirds. This is because the sealed building envelope optimizes thermal resistance by stopping any gaps where heated or cooled air could potentially escape. “The benefit is seen immediately and pays for itself in securing the thermal envelope of the building (roof and walls) better than traditional building materials,” says Lowery. “Our IMPs pay for themselves for years and years.” gb&d
SIGNIFICANT NEW ALTERNATIVES POLICY PROGRAM The EPA established this program to vet environmentally friendly substitutes for end-uses that have historically had elements that damage the ozone layer. They use factors like ozone depletion potential, global warming potential, toxicity, local air quality, effect, and others when determining what substitutes can make the list.
ELIMINATES STRUCTURAL ROT & MOLD Another way IMPs formulated with foam featuring Honeywell’s Solstice® LBA quickly recoup their initial cost is by requiring minimal maintenance and aftercare. Because they create a fully sealed building envelope, they prevent the travel of moisture from the exterior to the interior via tiny gaps in the insulation. This moisture travel in other building components can be responsible for mold and mildew—a time and money intensive cost that can be highly disruptive for building owners. “Because the building envelope is not only weatherproof, but provides an impenetrable membrane in cold storage, it eliminates mold and mildew,” says Lowery. MEETING NET ZERO ENERGY GOALS In 2008, the California
Public Utilities Commission (CPUC) set a goal that all new residential construction in California would be Zero Net Energy (ZNE) by 2020. “Insulated metal panels make it easier than ever to reach those standards—especially in roofing,” says Kim Harrell, vice president of sales for AWIP. “Our panels reduce energy needs, enabling the building owner to use less energy—realizing a savings in buying fewer solar panels—and still meet the 2020 standards.” Because of the high thermal performance (the foaminsulated panels can reach above R-50), AWIP’s metal march–april 2017
UP FRONT SUSTAINABLE SOLUTION

panels in conjunction with Solstice LBA play a huge role in helping new and existing construction comply with CPUC’s aspirations for the state of California. “We’re ready for 2020 in 2016,” Lowery says. Insulated metal panels reduce the need for specialized equipment— that means less fuel for cranes and less materials created for the express purpose of being used in a particular project. Additionally, they are extremely easy to modify should any changes be desired. “You can just cut in a new window,” Lowery says. Because of their light weight (they eliminate the need for a lot of structural support), mold resistance, and the fact that they serve as insulation and building material all rolled into one, they can be used anywhere in a building. “They’re an architect’s palette,” Lowery says. Their ultra-smooth construction means they snap together with ease, creating a sleek and modern aesthetic that is at home in a wide variety of residential and commercial projects. Whether customers are looking for a modern, sleek look in the FL40 flat panel, or even a troweled stucco facade in the HE40-Adobe model, AWIP’s choices are deep and varied.
FLEXIBILITY & SUSTAINABILITY Insulated panels have an additional benefit, especially in a location like California. In zones prone to earthquakes and tremors, panels are less rigid and more flexible than heavy, traditional building materials. They can even sway between 4 and 6 inches from side to side during seismic activity; think of the Oak and the Reed fable. To Lowery and AWIP, sustainability means products that last “the life of the building, and perform throughout its life cycle as well.” He says
the product will also pay for the investment quickly— in the case of the panels, reducing installation time and costs, the elimination of mold potential, and savings in the form of lower heating and cooling bills. “After that, it’s just making money for you.” True to form, Honeywell’s Solstice® LBA has an ultra-low global warming potential (GWP) of 1 and is registered with the EPA’s Significant New Alternatives Policy (SNAP) program; and AWIP panels contain no VOCs or ODP. Steel, a major component in the metal panels, is 100% recyclable and can be reused ad infinitum. “There is no endgame for steel,” Lowery says. “It could be a bicycle wheel next time around.” gb&d gbdmagazine.com

A GREENER PALETTE FOR PUBLIC SPACES B Y M IKE N N A P IEROTTI
We are entering an era of unprecedented environmental awareness. A majority (59%) of U.S. adults say stricter environmental laws and regulations are worth the cost, according to a December 2016 Pew Research survey. Add to that the sheer number of green design options and sustainable technologies emerging daily, and you have the perfect palette with which to redesign the future of the building industry. Increasingly, environmentally conscientious communities are dipping into this palette when creating public spaces, both for the long-term cost savings of sustainable, healthy building techniques and technologies, and for the inherent educational opportunity and aesthetic these spaces provide. Here, we explore three uniquely designed and successfully implemented examples of public spaces across the U.S., all with an educational focus, that were built green, both in their materials and in their philosophies. These inspiring spaces where history, beauty, nature, and learning merge have become shining examples of what can, and should, be done. PHOTO COURTESY OF THE ANDREW P. KASHEVAROFF LIBRARY

Henry Siegel, principal in charge, of Siegel & Strain Architects, admits the McClellan Ranch Preserve project was smaller than the work his firm normally takes on. But the passion of the city of Cupertino, California was infectious. “The city was really committed and had strong green goals,” Siegel says. “They had done a lot already to preserve park land and use it for environmental education. In fact, when we first went out to the site, they had groups of kids doing field studies and taking water samples right then. It's a pretty inspiring program.” This was an inspiring program in a landscape with an inspiring history, the team at
Siegel & Strain quickly realized. The 18-acre parcel had been agricultural for decades, since at least 1870, before the city purchased it in the 1970s. The site already housed the original preserved ranch home, milk barn, livestock barn, and several transplanted buildings—a replica of a blacksmith shop and an old water tower. With so much history already commanding attention in the landscape, the proposed environmental education center had to work in concert while defining itself as a modern facility with a sustainable focus. Siegel & Strain, with more than 20 years of sustainable building design experience, knew just how to approach a gbdmagazine.com

McCLELLAN RANCH PRESERVE BY THE NUMBERS According to a §2012 Harvard Business School study, public investment in LEEDcertified government buildings stimulates local economies, creating a near doubling effect in private investment. As of 2013, 47 §states in the U.S. have energy efficiency requirements for state-owned or funded public buildings that go beyond the state energy code. The LEED Silver certification, required in 16 states, is the most common mandate for public buildings. More than 800 state §government projects, more than 2,600 local government projects, and more than 1,800 K-12 projects are currently LEED certified. The World Green §Building Trends 2016 report by Dodge Data & Analytics finds green building activity in institutional buildings across the world— schools, hospitals, and public buildings—is expected to meet and surpass green building projects in other existing structures by 2018.
project like this. “It was a small project with a small budget. So we knew what was really most important was to get the basics right. We started where we always start. We asked ourselves, ‘How do you design a building as if it was unplugged?’” They began with assessing potential orientation, gauging daylight, and finding natural shading in order to come up with the best system for interior cooling—a big factor in an area of California known for its heat. The building’s envelope was also critical. These concerns, and a limited budget, necessitated one of the building’s most unique design features—its “L” shape. “We decided the best way to keep air conditioning costs down was to
put as much of the circulation of air into the rooms themselves. That meant no hallways. To get from one room to another, we used covered outdoor space.” This choice also helped keep lighting costs down. No hallways meant each classroom, the library, and the offices would have natural light on three or four sides. One early challenge, however, was inescapable. In order for the building to fit the landscape, it had to have a lot of western exposure in the front, where guests would enter. And that meant a lot of heat gain. “That side had to feel open and inviting yet block heat,” Siegel says. To solve this issue, the team designed a deep porch to shade the building entrance,

positioning the classrooms behind it, where they can open out into the porch, extending the learning space and creating an airy, sunlit feel. Perhaps the biggest technological feat of the project also turned out to be the center’s most valuable green teaching tool—the butterfly roof. “The roof is shaped to capture water and funnel it down into a cistern. Kids can actually watch this process
on a rainy day. The roof shape also allows PV panels to be placed in the best way possible in order to capture sunlight despite being on the north side of the building.” With PV panels supplying two-thirds of the building’s energy requirements, air conditioning was a big issue. Although Siegel & Strain always tries to stay away from air conditioning and its carbon
footprint, with the scope of this project and budget, as well as the area’s hot climate, they knew they couldn’t get away with using air circulation alone. So they turned to a system that uses a very efficient air source heat pump, using it for both radiant heating and cooling. Like many public building projects, the McClellan Ranch project had a limited budget, but with a bevy of sustainable design and technological options, it was never limited in potential. Opened in 2015, the project met its goals and stands as a testament to what even the smallest public projects can do both for their communities and the many future generations who will pass through their doors, inspired. gb&d
The Frick Environmental Center is a living building.
F R I C K EN VI R O N M EN TAL C ENTER
A Collective Vision The Frick Environmental Center was born of tragedy. In 2002 the Pittsburgh Parks Conservancy (PPC)’s old environmental center burned to the ground, leaving a gaping hole in public environmental education in the community. When the PPC and the City of Pittsburgh decided to build the Frick Environmental Center in the same location, the mission was to both “improve quality of life for the people of Pittsburgh by restoring the park system to excellence in partnership with government and the community,” says Patricia Culley, project architect, and to ensure the projects and its programs were conducted with respect to the environment, historic design, and the needs of Pittsburgh’s diverse region. Despite the potential complexities, Culley and the architectural team at Bohlin Cywinski Jackson, where she is an associate, were undaunted when they learned that, after a public qualifications process, they had been selected to lead the team. With the firm’s longtime focus on elegant humane design, energy efficiency, and environmental sensitivity—a focus that has earned it more than 625 design awards— they were a perfect fit.

Seeing the Pittsburgh community rallying around the cause was both inspiring and humbling. “The most surprising part of the project has been the sustained engagement of a vast assortment of people, from neighboring community members and environmental educators to SIZE the design and construction 15,570 square feet; 1,100 square feet of porches community, both locally and nationally. This is a testament to the importance of this COST project, and particularly its role as a public facility,” $13.75 million Culley says. Beginning in 2009, more than 1,000 people got VISITORS involved in the visioning Estimated 20,000 educational program and planning process for participants by year five the new center through dozens of public sessions and meetings sponsored by the PPC in partnership with the City of Pittsburgh. The result was a truly groundbreaking green design implemented by a team of artists, environmental restoration specialists, engineers, and architects—many of whom had deep ties to Pittsburgh and its parks. Construction began in 2014. Engineered to be a living building, the Frick Environmental Center meets the rigorous standards of the Living Building Challenge as well as LEED Platinum standards for energy efficiency. From its geothermal heating and cooling system to its native black locust wood rain screens, every element has both a technological and aesthetic purpose.
Once the lights came on, the 15,570-square-foot building used 40% less energy than a comparable structure. Some of its most innovative systems include a natural ventilation system that alerts users when outside temperatures and humidity are best for opening and closing windows and 161.7kW photovoltaic canopies over the parking area, offsetting 100% of the building’s energy use and capturing and filtering enough rainwater into a 15,000-gallon underground cistern to accommodate all toilet flushing, landscape irrigation, and the grounds’ historic fountain. None of these innovations came without challenges. Set in a forested grove, the center’s PV array could have suffered from shading and snow accumulation. But the design team had a fix. “Microinverters were designed into the system to ensure that any shading of the array could be tracked, and the landscaping design was then modified. An ongoing maintenance system is also set up for removal of snow and other debris.” This living classroom opened in September 2016, welcoming children and adults from across the city to its hands-on environmental education programs. Visitors can venture into the surrounding park’s gardens, meadows, and woodlands where 200 trees and 6,500 native plants have been planted, as well as see and experience the sustainable technology at work inside the building. “The vision of PPC is wide appreciation and enjoyment of a sustainable park system whose landscapes, facilities, and programming set world standards of excellence,” Culley says. gb&d

A 100-YEAR MUSEUM SIZE 118,000 square feet / 34,000-square-foot parking garage
COST $140 million / $101.7 million in construction costs
From the very first sketches, the new Andrew P. Kashevaroff Library, Archives and Museum in Juneau, Alaska was designed to last generations. “One of the original, repeated mantras for this project was to design it to be a 100-year structure,” says PCL Construction project manager Tyler B. Kautz.
Meant to house the State of Alaska’s historical archives and its most valuable, priceless artifacts, the museum (owned by the Alaska Department of Transportation and Public Facilities) would be the largest building project the city of Juneau had undertaken in 40-plus years. PCL Construction
was brought on to lead the endeavor together with a team of architects, civil engineers, landscape designers, and mechanical, electrical, and plumbing experts. That included designing building systems that would provide precise temperature and humidity control to safely preserve the items inside as well as an environment that would minimize handling of the artifacts—one that would last well into the next century. For PCL, incorporating green technologies was critical to meeting these needs. That included a cooling system powered by the tides—the primary source of cooling for the 118,000-square-foot building. “The building has three wells that pull brackish water from underneath the building, send it through a heat exchanger, and out into a culvert that feeds into the ocean. Constantly replenished by the tides, we have an endless supply of free cooling.” Air quality concerns were met with dedicated outdoor air units (DOAs) that utilize waste heat, pull heat and moisture from the exhaust air, and even treat it. To combat Alaska’s brutal weather, the building’s roof, exterior curtain wall system, below-grade concrete walls, and foundation were designed to withstand the worst wind, rain, and snow Juneau could throw at them. But aesthetics and using local, symbolic materials were just as critical in making sure the space became part of the community. The curtain wall system and exterior incorporated materials important to Alaskan culture—

For security reasons, the artifacts couldn't be stored offsite. “We had to develop a plan to demolish the old museum on the project site and [construct] the new museum while keeping over 32,000 historic artifacts onsite during the work,” Kautz says.

Throwing in the Towels The ever-popular Brooklyn Bowl earned its LEED certification with a lot of reused materials. But hot air hand dryers blew recycled paper towels off the premises.

By Russ Klettke
W When Brooklyn Bowl was LEED certified in 2011, it was the first bowling alley anywhere to achieve this designation. Its funky aesthetic—modeled after Coney Island—is an example of extreme recycling. Reconstituted truck tires make up the stage floor, while fixtures, furniture, glass space dividers, and the building itself (a former iron foundry) are repurposed and revitalized to serve this very lively place. But in the bathrooms you won’t find recycled paper towels for hand drying. Instead, Excel Dryer’s XLERATOR® Hand Dryers use electricity to quickly dry (in as little as eight seconds) the hands of up to 3,000 people who patronize the bowling-concert-restaurant establishment on any given day. Add to that the venue’s 200 employees who, as we know, must wash their hands, and that’s some big demand. NEW YORKERS WANT THE REAL DEAL
The common misperception of “100% recycled paper towels” is that they are somehow in an endless userecycle-use-recycle path. The reality is that while towel content is recycled, it all ends up being hauled into the waste stream after a single use. And that’s after materials are shipped to and from the recycling facility. A lifecycle assessment in 2009 of the XLERATOR dryer (conducted by Quantis International) looked at materials production, manufacturing, transportation, use, and end-of-life factors to see how this high-velocity air hand dryer performs relative to recycled paper towels. On a per-use basis, the air dryers were found to use 76 kilojoules of energy, about one-tenth the energy required to provide a paper towel drying (743 kilojoules). The assessment also accounted for sources of electricity, finding that a significant advantage remains present for these modern hand dryers even when the gb&d
OPERATIONAL EFFICIENCY EQUALS SUCCESS
These are numbers that mattered to the developer-owners of Brooklyn Bowl, Peter Shapiro and Charley Ryan. Their sophisticated clientele can see past a LEED plaque on a wall to question not just how a facility is built but also how it operates. To general manager Stephen Schwarz, it’s the operational performance that affects him every single day. “I actually used to hate air dryers,” he says. “They didn’t work.” But it’s the old dryers he’s referring to, which were much more common eight years ago when the XLERATORs were selected for the then-new facility. That impression changed when he saw how the new product performed, truly drying hands in a matter of seconds. What continues to sell him on air dryers is that restroom traffic flow is faster while maintenance is immensely simplified. “There is a need for speed in a club,” says Schwarz. “We make sure we have enough bartenders on staff to serve our customers. The same goes for the bathrooms. No one wants to wait.” Nor do they want clogged toilets from incorrect towel disposal, an operational challenge that plagues the entertainment and hospitality industry. The patrons at Brooklyn Bowl are indeed a study in motion. At its peak, bowlers take up all 16 lanes while restaurant patrons and concert fans fill its 3,000-person capacity hall. The facility is 100% wind-powered, with walls faced in Forest Stewardship Council–certified wood, a highly efficient HVAC system and waterproofed walls thanks to a soy-based, zero-VOC primersealer. The beer selection focuses on Brooklyn-made brews, the bowler’s lounge floor is made from recycled cork, and a bike rack outside accommodates at least 30 cyclists. This is actually the second venue for Shapiro and Ryan, who created something called the Wetlands
Greener, Cleaner, Creative Restrooms
Technological improvements and adoption have transformed a universal human experience: public restroom use. Count this as a smart response to science on both micro and macro levels. The Centers for Disease Control and Prevention emphasizes that pathogen transmission in health care is most common via hands. Providing an easy-to-use restroom makes hygiene more likely, even if it means resource consumption. Human behavior being what it is, product designers have developed automated fixtures
that make both clean and green more likely. This includes motion-activated (and low-flow) flush toilets, urinals, soap dispensers and sinks. Automated hand dryers with high velocity, quick-dry capabilities make it more likely that health care and restaurant employees, among others, wash and dry their hands thoroughly. Some products, however, such as trough-style hand dryers, are found to harbor germs just where they should be eliminated. So product development in some sectors is incomplete.
But none of this means the bathroom has to look like a hospital operating room. High-end restaurants employ stylized features such as hyper-efficient LED lighting with precise colors to match other décor. And Excel Dryer manufactures XLERATOR to employ digital imaging technology that allows the designer to devise any look they imagine. Perhaps the standard “Employees Must Wash Hands” message might take on a whole new, compelling look. It’s the challenge for eco-designers to show us what that might be.

power comes from fossil fuelburning plants. In the worst-case scenario—if electricity running the hand dryer is from coal-run plants while wind energy is used to produce 100% recycled paper towels—hand dryers make a 27% lower contribution to climate change than recycled paper towels.

Preserve in 1989 in Manhattan. It hosted bands as well as meetings for environmental activists. The move to Brooklyn 20 years later extended that idea, this time in a sustainable building. HAND DRYERS AS DESIGN STATEMENTS
The idea to use the XLERATOR at Brooklyn Bowl came about somewhat organically. A talent booker for the venue stepped outside her usual role to tell Shapiro and Ryan that she had seen the air dryers in other clubs. Apparently, she was quite insistent on both the point and the model: the high-speed, energy-efficient XLERATOR from Excel Dryer. It’s important to note that not all XLERATORs look the same. The manufacturer’s vice president of marketing and sales, William Gagnon, says the specific textured, gunmetal gray paint had been custom designed for Wembley Stadium in London (built in 2007). That style has proven to be so popular that it is no longer considered a “custom” cover, instead being added as a standard offering alongside traditional white, brushed stainless steel, chrome plated, metallic finishes like gold, copper, bronze, and more—making the Excel Dryer line of products the most customizable on the market. Some sports teams, like the New England Patriots at Boston’s Gillette Stadium, have taken advantage of Excel Dryer’s exclusive digital imaging technology, designing custom covers featuring their respective team logos. The technology allows the dryers to be branded with a fully integrated design, rather than a sticker or other surface brand that could easily be marred or removed. The result is a custom cover that matches both the buyer’s aesthetic and even the most eclectic restroom decor, as was the case with Brooklyn Bowl. gb&d

Range of sound created by higher velocity hand dryers; 60 is slightly above the level of conversation and 80 approximates the sound of a vacuum cleaner.

Brooklyn Bowl was a gut rehab, with entirely modern electrical systems capable of serving the demands of sound systems, video monitors, and lighting for the 80,000-square-foot facility. But Gagnon says a large portion of restaurants, schools, sports facilities, and entertainment venues are in older buildings where electrical systems might be decades old. Two dryers from the Excel Dryer line—the XLERATOR and the XLERATOReco—can also operate on the 15-amp circuits found in many older buildings. What’s more—with its “no heat” technology, XLERATOReco draws 4.5 amps or less, which allows for the installation of multiple XLERATOReco units on one circuit, significantly reducing installation costs and creating a return on investment of less than one year. An environmentally conscious public increasingly embraces recycled materials. But Brooklyn Bowl and the XLERATOR demonstrate how a rational and objective review challenges assumptions that all recycling is the greenest option. In this bowling alley, blowing hot air is the winning game. gb&d march–april 2017
AND SUSTAINABLE, TOO VersaCore+Green™ wall systems, created by FABCON Precast, meet the criteria for sustainability, giving buildings a higher percentage of recycledproduct content, a higher level of energy efficiency, and load bearing wall panels that support equipment loads and protect your data from potential weather or security damage. VersaCore+Green wall panels incorporate up to 58% recycled content, as well as the potential for increased LEED points and tax credits. And because panels are lighter in weight, fewer hauling trips are required, which reduces not only cost, but carbon footprint as well.

Structural precast wall panels fulfill extraordinary building envelope requirements that ensure data is safe and secure, with the ability to withstand high winds, fires, and other natural disasters. That’s why when one Ohio company needed to build a new data center, it chose Fabcon— the American company that’s been doing this work for more than 45 years. “First, Fabcon has a great reputation,” says Quandel’s Andy Bensman, the project manager for the Five 9s Data Center in Ohio, a 30,000-squarefoot data center that opened in late 2015. “Second, they have gb&d
an indoor production facility that allows them to maintain operations in winter, which was crucial for our construction schedule.” Indeed, tight schedules are common in the world of data center construction. Once an owner decides they want to build, has their contractor and architect on board, and secures funding, data center projects move at the speed of light, says Matt Smith, national accounts manager for Fabcon Precast. “They’re very fast schedules. That’s where speed of construction comes in.” Chris Crosby, CEO of Compass
Datacenters, emphasizes that point for his co-location developments. “We have a six-month guarantee to our customers to have their data centers up and running, so I need to find a reliable, efficient solution that is strong enough to meet our rigorous safety standards. Fabcon’s precast walls provide that for us.” Fortunately, speed is the biggest benefit of using precast wall panels. Precast concrete is one of the fastest building systems available. As for Fabcon, they can set 200 to 250 lineal feet of wall per day. If you think about a march–april 2017

Fabcon engineers and produces its panels in one of four U.S. production facilities and ships the finished product to the job site in as little as eight weeks, whereas a smaller outfit could take months longer. And you don’t have to hire another crew to erect the panels once they arrive onsite, like with some precasters. Fabcon brings a small team—five or six people—to set their own panels, to further save time and labor, making it easy to do business, rather than having to hire another crew. Fabcon also has the largest wall panel production capacity of any precaster in the country, Smith says. “Because of our large manufacturing capacity, we have the
shortest lead times typically.” Bensman says the install was fast and efficient—turnkey with no issues. Five9s also just so happened to take home the best office/medical project award at the NAIOP Central Ohio Awards Gala in 2016. “High quality products are a priority on every project for Quandel—precast wall panels are no different,” Bensman says. “Fabcon knows how to push from design to production quickly so you can achieve your overall schedule goals.” WHY PRECAST?
Since the panels are produced at one of Fabcon’s manufacturing facilities and shipped directly to the job site, Smith says the process is less disruptive than other building methods like masonry, which requires you to set the wall block by block, taking up a lot of time, space, and labor.
Smith says other data centers may instead turn to tilt-up construction—a process that involves pouring a slab onsite, letting it cure, then tilting it into place. But that’s not always an option in northern climates near where many of Fabcon’s plants are located (Pennsylvania, Ohio, Minnesota, and Kansas), as you’re often unable to pour during inclement weather. “It’s very messy on many job sites for at least half of the year, but it’s easy for us to set panels year-round,” Smith says. That’s another reason why the Five 9s Data Center project chose Fabcon— construction in winter. And while you may incur hauling costs to get the panels from, say, Kansas to Texas, you’ll not only save time and labor on the job site, you’ll have higher quality panels, since they were poured in a controlled gbdmagazine.com

environment. “There are no weather issues, and we’ve got our quality control professionals at the plant to oversee things,” Smith says. Your site will also encounter minimal disturbance, allowing other trades to move about the site more efficiently. RESILIENCE & STRENGTH
Fabcon’s precast concrete is stronger than competitors’ because of its unique panel cross-section of solid concrete and prestressed strand—or the cables that run the full length of the panel that give it strength. Fabcon’s panels can also be load-bearing up to 60 feet tall, while precast panels produced by others only go as high as 40 feet and have to be reinforced with additional steel. And they’re versatile. Fabcon’s wall systems have been used on everything gb&d
from 5,000-square-foot centers to multi-million-square-foot projects. Fabcon can produce panels that range in width from 24 inches to 13.5 feet wide and depths from 8 to 12 inches. They also offer an extensive variety of finishes— exposed aggregate, integral color, sand-blasted, and acid etch, to name a few. Airborne debris is often the source of damage to buildings during high winds, but Fabcon’s wall panels are highly resistant to the impact. Fabcon’s panels withstand forces of 8,000 to 11,000 PSF and have been proven to stand strong even after impact from airborne debris in a study conducted by the Wind Science & Engineering Research Center at Texas Tech University. “Providing our customers with the most efficient, technologically advanced and damage-resistant
data centers is our point of differentiation, and Fabcon’s precast panels are an important aspect of our success,” says Crosby. Different buildings often have different security requirements. A bank, for instance, may have a Tier IV security requirement—its walls must withstand everything from high winds to flying debris. Fabcon’s precast panels are made to withstand up to Tier IV load requirements. A few years ago, Fabcon worked on a data center for a major financial institution and went above and beyond to test their durability—shooting 15-pound two-by-fours at 150 miles per hour and 75-pund metal pipes at 75 miles per hour into the panels. “Our panels passed the test with flying colors,” Smith says. gb&d

50 Sustainable, Strong, & Steel The Steel Market Development Institute in Pittsburgh is leading the way.

STEEL MARKET DEVELOPMENT INSTITUTE
THE STEEL MARKET DEVELOPMENT INSTITUTE SETS THE RECORD STRAIGHT, SHOWING STEEL IS HERE TO STAY— AND WHY THAT’S IMPORTANT 52
When you close your eyes and picture a steel mill, you may be conjuring up an image of the steel production industry of old. “Some people still have the picture of an older industry when they think of steel production,” says Mark Thimons, vice president of sustainability for the Steel Market Development Institute (SMDI) in Pittsburgh, a business unit of the American Iron and Steel Institute (AISI). But today’s steelmaking facilities employ state-of-the-art technology and are much cleaner, Thimons says, resulting in an energy use profile that has decreased significantly over the years. “Additionally, CO2 emissions per ton of steel have been reduced by over 35% since 1990.” LEADING THE WAY Pittsburgh itself is in the midst of an incredible revitalization while still embracing its industrial roots, according to Brandie Sebastian, life cycle assessment manager for the Steel Recycling Institute, a business unit of AISI. “There is an impressive sustainability culture here that is highlighted by the Green Building Alliance, one of the most reputable and influential green building organizations in the U.S.,” she says. In addition, the International Living Future Institute is working to open a Living Futures “hub” in Pittsburgh that will focus on sustainable and healthy construction products. SMDI is leading the way when it comes to educating the building construction industry and the public about steel. The organization works to grow the markets for steel in the automotive, construction, and container industries as well as in nontraditional steel markets like energy. And SMDI is made up of some serious innovators— going above and beyond when it comes to transparency and asking, “How can we be even better?” In the last few years, the SMDI team has been working on comprehensive EPDs, or Environmental Product Declarations. EPDs summarize the gbdmagazine.com

results of Life Cycle Assessments, or LCAs, which assess the environmental impacts associated with a product’s life cycle—from raw material extraction through materials processing, manufacture, distribution, use, repair, and maintenance. You might liken EPDs to nutrition labels on food packaging, as they present information to help consumers make informed decisions. In the last few years, SMDI and other customer associations have produced EPDs for nearly all of the basic steel products used in construction, such as steel studs, decks, joists, beams, and more. You can find all of those EPDs at buildusingsteel.org and download them for free. “An architect or designer can now go to one location and find all of these steel product EPDs,” Thimons says. EPDs are used by architects and designers to gain a better understanding of the potential environmental impacts of construction products, and thereby a better understanding of the gb&d

environmental impacts of an entire building. One of the primary drivers of the demand for EPDs is LEED, which allows credits or points within the program for the use of products that have published EPDs. SMDI also emphasizes education and working together. Twice per year, dozens of steel producers, customer association representatives, and companies that make steel products meet as part of SMDI’s Construction Sustainability Council. There, they discuss industry challenges, upcoming projects, and opportunities to collaborate toward resolving common issues. Years ago the steel industry, like most industries, was somewhat less attuned to sustainable construction issues. The early meetings of the Construction Sustainability Council—which started roughly seven years ago—included a lot of education on developments and trends and helped raise awareness about the significance of LCAs and EPDs. These days, meetings are more collaborative. “It’s more efficient for us to share lessons learned from projects and not duplicate efforts and funding. This has been a very effective process,” Sebastian says. INSPIRING RESEARCH CONTINUES Currently, SMDI is working on multiple projects in the automotive and construction markets, including some whole building LCA comparisons of wood versus steel. That work should be complete in 2017. Sebastian says, ”We engage the design firm to do the building design march–april 2017

and develop the bills of material for us. Then, the next step is to look at the steel designs and see if there are ways to optimize them.” SMDI is also working to compare steel produced in North America with steel produced in other parts of the world to see whether their environmental impacts differ. And SMDI is collecting new steel production data as part of the Life Cycle Inventory (LCI, which measures the material flows, energy flows, and environmental releases for the production of a defined amount of a product) for North American steel production. “That’s a pretty major effort in 2017,” Sebastian says. RECYCLE, RECYCLE, RECYCLE When it comes to sustainability, steel can’t be beat. Each year, more steel is recycled in the U.S. than paper, plastic, aluminum and glass combined. “It’s one of the few construction products that is not only recycled routinely, but it can be 100% recycled—meaning any steel product can be recycled into any other steel

product,” Thimons says. A recycled steel beam can become a car door or part of a refrigerator and so on. And it can be done so continuously, without losing strength. All new steel has some recycled content. A steel beam made in North America, for instance, has 90% to 100% recycled content. And North American steel is always made with at least 25% recycled content. Structural steel is recycled at about 98%, whereas steel in general has a recycling rate in the high 80s. And anywhere from 60 to 80 million tons of steel scrap are recycled every year into new steel products in North America. Looking at how the industry can continue to make strides is ongoing, Thimons says, and that’s all part of SMDI’s mission. “Steel producers are continually looking for innovative ways to increase the energy efficiency of the steelmaking process, and we are hopeful that the comprehensive collection of steelmaking LCI data will help us identify additional avenues for improvement of the environmental profile of North American steel products.” gb&d gbdmagazine.com

HINT: THINK OF IT LIKE A HOME
Literally. Her dad was a physician, her mom a nurse, and nearly every aunt, uncle, cousin, and grandparent in her family worked in health care in some capacity. As a child, she spent many hours hanging out in her father’s waiting room, reading books and imagining that one day when she grew up, she too would tend to patients, combining TLC with medical expertise to improve the lives of those who are ailing. Most of that vision has come true, except Harrison now uses design expertise, not medical expertise, to help those in need of healing. “Hospitals are a place where people are incredibly stressed and going through what may be

the worst thing that will happen to them in their lives,” says Harrison, now a senior principal at Stantec’s San Francisco office and the health care sector leader for the company’s West Coast operations. “We need to build them in a way that makes people feel better, safer, cared for, and less stressed. It was a real ‘aha’ moment when I realized I could influence that through design. It’s something I feel very passionate about because of how I grew up—but it’s an incredible challenge.” It’s a challenge that Harrison has been picking apart throughout her career, but in 2015 a milestone arrived: the $1.5 billion UCSF Medical Center at Mission Bay, one of the largest and most innovative new medical facilities in the country, opened its doors after 10 years of planning, design, and construction. Located on a 14.5-acre site along the eastern edge of San Francisco, where it overlooks the magnificent San Francisco Bay, this 289bed, 878,000-square-foot LEED Gold complex is comprised of three distinct facilities: a children’s hospital, a woman’s hospital, and a cancer hospital, all of which are part of UCSF’s research network. Harrison, who was the project director, says UCSF gave the design team a “real
mandate around health and sustainability ... so the project wasn’t just about engineering sustainability in the building, but about building a healthy environment in every aspect of the word.”
“IT’S ABOUT BUILDING A HEALTHY ENVIRONMENT IN EVERY ASPECT OF THE WORD.” Laurel Harrison, senior principal at Stantec

WHY HOSPITALS SOMETIMES MAKE US SICKER Gary Cohen, president and co-founder of Health Care Without Harm, says the leading source for patient harm in hospitals is “hospital acquired infections,” also known as HAIs, which impact upwards of 2 million patients per year in the U.S. The biggest culprit in his view? Shared patient rooms, rather than single occupancy spaces. Newer, cutting-edge hospitals are being designed to have much more natural light, and a quieter, more soothing environment, which single occupant rooms help to ensure. “It has only been recently that research has validated what patients have been saying for decades, which is that the noise in hospitals prevents restful sleep and disturbs the healing process,” Cohen says. Such features typically cost more up front, but Cohen’s analysis is that they more than pay for themselves in the long run. “The financial decision-makers in hospitals are often engineering out these more high-quality spaces in their facilities. But we need to move beyond upfront costs to evaluate the long term ROI. If you factor in reduced HAIs and faster patient recovery, it pencils out.” Another huge issue: toxic chemicals in both medical products and hospital furnishings and finishes. Cohen says PVC-based blood bags, for example, leach DEHP (a reproductive toxin) into

patients. Safer alternatives are nearing commercialization in Europe, paving the way for them to enter the U.S. market. Every year, more and more nontoxic materials enter the health care industry supply chain, and Cohen is seeking to spark a cultural shift within the industry to encourage their adoption. “There are many alternatives on the market,” he says. “But Group Purchasing Organizations have done little to promote them. Often, if they do put them on a contract, they also put the ‘brown product’ on the contract as well, which often costs less. So we need to incentivize the market for safer alternatives.” Green Health Exchange, a new purchasing cooperative, spearheaded by Health Care Without Harm, is working to do just that. As production scales up, the safer products are becoming more affordable, sometimes more so than the older, more toxic products.
ENVIRONMENT & HUMAN-FRIENDLY The UCSF Medical Center embodies much of Cohen’s vision for what a healthier hospital looks like. A few aspects of its environmentally friendly features are also worth noting. For starters, the facility is designed to use 50% less energy than the average U.S. hospital. Water conservation strategies at the site are expected to save 4 million gallons per year. And 90% of construction waste was recycled, rather than sent to the landfill. You’ll also find 10 electric vehicle charging stations in the parking deck. The center is also green in a literal sense—with 4.3 acres of landscaped gardens, including 1

Qualities of a Healthy Health Care Environment
Gary Cohen, president and cofounder of Health Care Without Harm, believes that scaling up eco-friendly and nontoxic product lines is one of the most effective means to building a healthier health care industry. That’s why he’s worked very hard for the last several years to develop the Green Health Exchange, a purchasing cooperative that now counts more than a half-dozen major health care systems in its membership. “We’ve come to the conclusion that if we can aggregate the purchasing power of all these hospitals we would accelerate market transformation toward safer products a lot faster,” Cohen says. “We’re saying to suppliers, if you want to buy from us, you have to disclose what is in your products. They can’t afford to turn down a $10 or $20 million contract because they didn’t share what chemicals they use. It’s become a powerful lever for transformation.” Green Health Exchange is still in its infancy, but it’s already driving down prices for better quality products and materials. Cohen says flame retardant–free furnishings have suddenly become cheaper than those with toxic flame retardants. “How absurd is that?” he says. “You actually have to pay extra to be poisoned. We’ve stimulated the other big purchasers in the sector to start beefing up their own sustainability staff. They realize there is a real competitor on the market now, so they’re paying attention.” Cohen suggests 10 ways health care facilities can become better models of health and well-being:
1 Maximize natural light. “People feel better, use less medication, heal quicker, and leave the hospital sooner under natural light.”
2 Exposure to nature. “It’s intuitive, but there’s actually research that suggests views of nature help people heal quicker.”
3 Minimize noise. “When there’s lots of bells and whistles and noises and machines going on, it’s very disturbing, especially for patients’ sleep.”
4 Provide individual patient rooms. “Research shows that individual patient rooms are preferable for reducing hospital acquired infections—they also make it easier for family members to stay with their relatives who are undergoing treatment.”
5 Lose the institutional vibe. “Making hospitals feel like less of an industrial place, and more welcoming, is really important.”
6 Serve healthy food. “Providing healthy, sustainably produced food supports healing and models healthy habits for patients, workers, and visitors.”
7 Eliminate toxins. “It’s a no-brainer at this point. Many of the nontoxic alternative products are now cost competitive or even cheaper.”
9 Install “smarter” lighting. “There are new kinds of lighting that stimulate melatonin production at night, so you can sleep better, and stimulate cortisol during the day to keep people more alert. For patients, it encourages a schedule that promotes rest.”
10 Expose stairwells. “If people can see the stairs, they are more likely to use them, rather than opt for the elevator.”
acre of rooftop gardens—which is where Harrison says the features for environmental health begin to overlap with those intended to support human health and healing. The ground-level gardens, for example, are a boon to employees and visitors, who can soak up the sun and meditate on the birds, butterflies, and bees buzzing around the native plantings as a reprieve from the heavy reality indoors. Many hospitals these days, especially those in more spacious suburban settings, have incorporated such “healing gardens,” but what about the patients who are not well enough to venture out of their room, down the elevator, and out into public space? This is where the center’s terrace gardens— located on three extensive roof decks adjacent to floors where inpatient rooms are located— come into play. Patients who are in the hospital for an extended period have easy access to a quiet, inviting outdoor space. And for those who are too ill to visit one of the terrace gardens, each inpatient room has what Harrison calls a “sky porch,” a

balcony where patients can drink in the fresh air, feel the sun on their skin, and take in the view— most of the balconies overlook the bay or the terrace gardens. “We want people to be able to step out and see and touch the natural environment without having to go all the way through the building and back out the front door,” Harrison says. “The sky porches allow you to experience that while you’re still within the safe environment of care, which is really lovely.” If such luxuries sound like something you’d want in your own house, it’s no accident. The center was designed to feel like a home away from home, as study after study has shown that a nurturing physical environment is an invaluable complement to medical care. This is also why natural materials and organic forms predominate in the interior design scheme for the three hospitals, along with soothing color palettes and nature-inspired artworks that are intended to create a peaceful ambience. Ceiling tiles and flooring surfaces were chosen to absorb sound, rather than amplify
it, as is often the case in more “institutional” facilities, a category in which hospitals are too often lumped that conjures up warehouses and military bases more than a place to heal. Here and there are tiny meditation rooms with soft music, and lounges designed with faux fireplaces and other features reminiscent of a family room. Speaking of family, all inpatient rooms have sufficient space and furnishings to allow family members to stay with their relatives while they receive care, which unfortunately is not the norm at other health care facilities. “The center has health—in the most global sense—at its heart,” says Harrison.
KAISER PERMANENTE RAISES THE BAR Just a few blocks away from the UCSF Medical Center is another new medical facility that’s raising the bar on healthy health care design. Kaiser Permanente’s Mission Bay Medical Office Building, which opened in March of 2016, is the health care giant’s most
ambitious facility to date, in terms of sustainable design. The nine-story, 220,000square-foot LEED Platinum building houses a variety of outpatient services, ranging from dermatology to physical therapy to health education. It is also home to a number of sustainability features, including a verdant green roof that acts as a sponge slowing down storm water runoff and provides habitat for birds and beneficial insects. All of the lighting is LED, resulting in energy savings more than 30% above LEED standards. A system of “purple pipes” waits behind the walls for the city of San Francisco’s soon-to-be-completed non-potable water reclamation program, infrastructure that will be tied to the center’s bathroom plumbing and used to flush toilets. But as with the UCSF facility up the street, Kaiser Permanente’s Mission Bay facility is a case study in healthy health care design. For example, 90% of the occupied spaces have natural daylight, which saves energy and money, but has also been shown to encourage healing and well-being. Also

Kaiser Permanente’s sustainability scorecard requires suppliers to provide information on their company’s environmental commitment, use of potentially harmful chemicals in their products, and information about product and packaging recycling. 62
important to occupant health and comfort are the sensors installed in ceilings throughout the building that monitor temperature and carbon dioxide, communicating with the HVAC system to constantly fine-tune airflow—100% of which flows in fresh from outdoors. Jay Murphy, the San Francisco team manager for Kaiser Permanente’s national facilities services department, notes that many of these features impact occupants without them even realizing it, but there is one unique aspect of the facility that gets constant attention: its artwork. Thematic pieces relevant to each department in the building were chosen from a group of over 30 local artists commissioned by Kaiser Permanente. “For example, in pediatrics the artwork is fun and playful,” Murphy says. “It’s hard to describe, it’s one of those things you just have to experience … [but] we really thought about how people would feel when they walked in and saw the art. And what I’m hearing is that everybody notices the art, that it makes them feel good, makes
them happy. That’s good, because that’s what we’re trying to do.”
PREVENTING ILLNESS WITH NONTOXIC MATERIALS If improving occupant experience is one half of the equation of healthy health care design, the other is weeding out anything in the space that could actually make people sicker. Kaiser Permanente’s Mission Bay facility employs 70,000 square feet of PVC-free flooring and contains low or no emissions carpeting throughout. But the focus on sourcing nontoxic materials extends throughout the organization’s health care network. “We have ambitious goals and standards for product sourcing, including eliminating chemicals of concern in fabrics, finishes and furniture, as well as in our medical products,” says Hilary Costa, a senior communications consultant at Kaiser Permanente’s Oakland headquarters. Costa is referring, in part, to the organization’s 2025
Environmental Stewardship Goals, one of which is to
increase the purchasing of safer products and materials by 50%. But it’s an effort that’s been underway for quite some time. In 2010, Kaiser Permanente developed its own “sustainability scorecard” which rates the products in their supply chain on both environmental criteria and on how non-toxic they are. The goal is to leverage the organization’s immense purchasing power—with 10.6 million members enrolled in its health plans, 38 hospitals, and 626 other medical facilities throughout the country, Kaiser Permanente is the nation’s largest not-for-profit health network—to reshape the health care supply chain. In the first year of the program, the organization required environmental data to be reported for $1 billion worth of supplies and materials. Since then, the sustainability scorecard has been shared with other major health care organizations across the country—which have an estimated annual purchasing volume of $135 million—to truly move the needle toward creating less toxic, more environmentally friendly health care environments. All these pieces have come together to make the Mission Bay building a leading example of what the health care environments of the future might look like, Murphy says. “From the artwork on the walls and the colors we used in the design to the daylight throughout the space and the furniture and finishes we selected—it all contributes to a whole health environment, promoting the heath of the environment and the well-being of the occupants.” gb&d gbdmagazine.com

VANCOUVER’S QUEST TO BE THE GREENEST By Laura Rote
PHOTO: ANDREW LATREILLE
Vancouver has long been a progressive city—Greenpeace was founded here in the 1970s and it continues to be a mecca for sustainability. But this major city (with a metro population of 2.3 million and home to countless blockbuster film shoots) also has the smallest carbon footprint of any major city in North America, and it seems no one on the ground has any intention of letting that designation slip. Vancouver Mayor Gregor Robertson says the city is committed to making Vancouver the world’s “greenest city” by 2020. See how that’s coming along for yourself on a self-guided Green Buildings Audio Tour, or turn the page for just a few of the stellar projects helping to make continued accolades possible.
The Vancouver House project aims to reclaim a site beneath a busy city bridge.
MORE THAN A BUILDING Rising 52 stories in the sky, Vancouver House is not what it appears at first glance, though even that is quite impressive. Yes, Bjarke Ingels Group’s Vancouver House will be one of the most technologically advanced high-rise residential buildings in the world when it is finished, and it’s expected to be one of the world’s first LEED Platinum-certified residential towers. But it also incorporates streets and pedestrian pathways in ways you’ve never seen. “Vancouver has already embarked upon an urban experiment in creating a super dense residential downtown to increase pedestrian activity and street
life,” says Thomas Christoffersen, BIG Partner. “With this project we attempt to continue this process of densification by reclaiming a site beneath the bridges that would otherwise be lost as a lifeless ‘black hole’ in the urban fabric.” Instead, this design allows for traffic above to create a new form of weather-protected urban space below. Trisected by an overpass and burdened by setbacks, the tower will maximize its mass where it has the most impact. At its base, a nearly 100-foot setback from the highway gives it a triangular footprint on the ground. As the tower gets taller—and wider—it also clears the zone of noise and visual pollution. “It then exploits the
opportunity to overcome the setback and reclaims the valuable area. In doing so, it provides an icon for the city’s skyline and a generous public space at its base,” Christoffersen says. The podium is a mixed-use urban village, with spaces for working, shopping, and socializing that all look out onto public plazas and paths. The tower itself will be 80% residential, 10% offices, and 10% retail. “This is not just a building, but the start of a new neighborhood,” Christoffersen says, adding that the three buildings that make up Vancouver House, along with the Granville bridge, create an exciting area that can accommodate all kinds of events. gbdmagazine.com

RISING TO THE OCCASION Vancouver House has already received many awards, from the Canadian Architect Award of Excellence 2015 to the World Architecture Festival Future Project of the Year, but step one in the project was finding the perfect location. The team sought a spot that encompassed smart growth principles while creating a dynamic sustainable hub in a residential community. And it had to be beautiful. “We’ve designed this project with the mindset of ‘gesamtkunstwerk,’ a term that German opera composer Richard Wagner used to describe opera,” Christoffersen says. “It roughly translates to ‘a total work of art,’ referring to the act of combining all art forms into a single piece.” Adopting this philosophy, Vancouver House is designed from the smallest detail to the largest elevation. But this also includes aiming for the epitome of “greenness,” with features like a passive envelope, triple glazing, deep balconies that shield units from harsh light, green roofs, and an extensive rainwater
management system. Inside, Vancouver House will have highly efficient LED lighting, occupancy sensors, daylighting controls, and radiant ceiling heating and cooling in offices, among other sustainable attributes. Materials used during construction contain recycled and regional materials as well as those that promote a healthy indoor environment. More than 75% of materials will be kept out of the landfill. In terms of energy and rainwater management, the Energy Use Intensities (EUI) have been set at 115kWh/m2 per year for the residential building and 121kWh/ m2 per year for the office spaces at the podiums. Rainwater will be used for irrigation through a rainwater harvesting system for 100% of irrigation demands in addition to a 40% water reduction for potable use in all buildings. A water resource management plan is also being created for vegetated roofs and permeable spaces to reduce stormwater runoff. Mechanical systems will use 100% fresh and UV-treated and carbon-filtered outdoor air with no recirculation. Similarly,
all domestic water will pass through a reverse-osmosis filtration system, and residences will be served with a highly flexible and efficient top-end hydronic heating and cooling system. A LIVING SCULPTURE The building’s peculiar shape requires a unique structural system. Vancouver House will be the first project in the city to use vertical post-tensioning and a robust walking column system. And rather than feel restricted in design by city regulations or obstacles like traffic, BIG uses those urban conditions to its advantage to create new opportunities. “Vancouver House is a contemporary descendant of the Flatiron Building, one of New York City’s most iconic landmarks,” Christoffersen says, noting that its triangular site was considered unusable because of its shape until increased real estate prices and advanced technology in construction made it possible. “Similarly, Vancouver House’s form is a result of its circumstances: a trisected site, existing infrastructure, and concerns for neighboring buildings and parks. The sculptural silhouette is not the result of formal excess, but rather the consequence of design and real estate optimization; it appears different because it performs and responds differently.” gb&d march–april 2017
SUSTAINABLE BY THE SEA On a remote island off the coast of British Columbia, the Bella Bella Passive House proves anything is possible
When a fire destroyed hospital staff housing in a remote part of British Columbia, no one was surprised by the plan to rebuild. But its location on rugged Campbell Island— where most of the 1,500 people living on the island belong to the Heiltsuk First Nation and it’s not uncommon to see whales swim by—made access to supplies and construction crews tricky. Add to that the decision to go from LEED to Passive House standards, and the undertaking was no small feat. But it was all accomplished in just nine months.
The Bella Bella housing exists to help attract health care professionals to the farflung hospital, which is part of Vancouver Coastal Health (VCH). The Bella Bella Passive House for employees at R.W. Large Memorial Hospital is made up of six, two-story attached townhomes. VCH has long been committed to energy conservation with sustainability policies that govern the design and construction of their health care facilities. But since the Bella Bella project wasn’t a clinical project but simply residential, the decision-makers were allowed to think

outside of the box. That’s where prefab plus Passive House comes in. “It presented an opportunity for VCH to be innovative in trying a new energy conservation strategy more closely designed to meet residential needs,” says Glen Garrick, sustainability manager, transformation and innovation for VCH. “In the end the project was completed at a cost of $2.6 million—about $500,000 less than it would have cost to construct the development onsite.” Considering its remote location—you literally have to travel over ocean from the mainland to get there—getting a construction team and supplies to the site was a top challenge. And finding the supplies and technical abilities there would be difficult, too. “A prefab structure taken up by barge presented a very quick and cost effective way to efficiently meet what would
be needed in Bella Bella,” Garrick says. “They needed staff housing as soon as possible.” The prefab structure was designed, constructed, and tested in a closed environment, ensuring a high-quality build and eliminating concerns like weather. Each story of each townhome was a module in and of itself—each approximately 32 by 14 feet, weighing more than 30 tons—made at a Britco factory in the province. The woodframe construction included mineral wool, fiberglass insulation, and metal cladding built to Passive House standards, airtight windows, split-system heat pumps, and heat and energy recovery ventilation units. While the modules were being built in the factory, prep work started on the Bella Bella site—a common prefab practice that can result in a 30% shorter construction period. While the process wasn’t without its myriad discus-
sions, all of the back and forth decision-making paid off in the end. “Whenever you push the envelope or try something new, it makes people uncomfortable,” Garrick says. “And those responsible for budgets and maintenance of facilities like this are the most anxious when trying something completely new. In the end, facilities management along with the energy and environmental sustainability team were able to educate key decision-makers enough to gain a level of trust to get the project approved.” At the end of the day, it’s all about saving energy. While the final results haven’t yet been measured and verified, Garrick says the savings is clear. “On one of the coldest nights of the year in Bella Bella, the occupants can still be kept cozy with just 600 watts of energy—that’s the equivalent of six incandescent light bulbs.” gb&d march–april 2017
Natural light fills the Langara Science & Technology building, from a massive light well to large windows in classrooms.
LET THERE BE LIGHT A bright environment breeds bright students at Vancouver’s new Langara Science & Technology building Photos by Andrew Latreille
It’s only fitting that the building with some of the most inspiring lessons on campus would also be inspiring in appearance. Aesthetically, sustainably, practically—the Langara Science & Technology Building on the campus of Langara College in Vancouver, British Columbia is more than 129,000 square feet of greatness. “We tried to take advantage of every available space to give back to the students,” says Kori Chan, the principal from Proscenium Architecture +
Interiors Inc, who worked alongside principal Stephen Teeple of Teeple Architects on this project. Chan says his favorite parts of the new Langara building are the student common areas—particularly the Vortex Lounge. “It’s the multi-story space at the northwest corner of the building that contains an oculus in the shape of a crystal,” he says. “The oculus is a spectacular window system designed to draw daylight into the student areas.”
CRYSTAL CLEAR Natural light fills the five-story building—home to science, nursing, and computing science labs as well as collaborative study spaces, an instructional greenhouse, and an observation deck. You’ll encounter outdoor views in more than 90% of regularly occupied areas. “Natural light promotes a healthy environment. People feel better when there is natural daylight,” Chan says. “The more natural light we can get to penetrate the building, the less ambient lighting we need to use, thereby reducing energy consumption. The challenge is controlling glare.” The design team used translucent panels on the lower floors and an architectural screen on the top three levels to combat glare while letting in as much natural light as possible. Then there’s the light well— beautiful and practical. It acts as a return air shaft by taking advantage of how air moves naturally to reduce the need to move it mechanically. And it also allows daylight to shine through the entire building. gbdmagazine.com

As one thermal energy waste and preheats domestic of the many examples hot water of its commitment to sustainability, Langara goes above and beyond with efficient indoor water use. The project created a model estimate of its indoor water use for plumbing fixtures and found the building could
save more than 260 gallons of potable water a year by specifying low flow fixtures with aerators for additional efficiencies. That’s an Olympic swimming pool amount of water each year, or 44% in savings. Outside, the project includes a large landscaped area that’s protected from future development. The green space serves as an offset for the building in an effort to conserve existing natural areas, provide habitat, and promote biodiversity. And, of course, any fertilizers used there are phosphate-free. Throughout construction, the project team used low-emitting paints, coatings, adhesives, and sealants in a commitment to air quality. Special attention was paid to flooring emission standards, ensuring the building met the FloorScore IAQ Test Program, which independently certifies that flooring products comply with VOC emissions criteria. Oh, and when it comes to even getting to the building, you’ll find easy access to public transportation and a cycling route. If you do drive,
though, you can recharge your electric vehicle onsite, or park in “preferred parking” if you carpool. Langara encourages minimal vehicle miles and rewards alternative modes of transportation. INHERENT TO THE OUTDOORS The building is designed to fit seamlessly into its environment. While building sites often have asphalt parking areas or dark-colored hardscaped areas, this project doesn’t, Chan says, in an effort to mitigate the heat island effect. Instead, it has what’s called high albedo or low-emissive materials, for lighter, more reflective hardscaping surfaces. The new building is pursuing third party certification via the Canada Green Building Council, aiming for LEED Gold. “This project incorporated a number of efforts to ensure site development impacts were lower than that of a conventional building,” Chan says. From the outside, the building adds just the right amount of texture and pattern without competing with its surroundings. gb&d gbdmagazine.com

Storage rooms, closets, and bathrooms used to be the only choices for nursing mothers at work. As an architect and sustainability leader at the Centers for Disease Control and Prevention (CDC), I set out to change the built environment for the better. Knowing everyone doesn’t know what working mothers need, I worked with universities, architects, and lactation experts to author the American Institute for Architects (AIA) Best Practice Guide for Lactation Rooms. This document translates science into guidance for designers and is highly regarded in the medical and architectural community. HEALTHY SPACES

privacy (lockable door), lighting, HVAC, and refrigeration. A location with or near a sink is required. The room should be equipped with a table, chair, nursing stool, mid-size or compact refrigerator, cleaning supplies and a hospital-grade, FDA-approved electric breast pump. Anticipated “useful accessories” include trash cans, paper towel dispenser, coat rack or hooks, and a fulllength mirror. Other considerations include soothing color palettes and a room schedule. Just as the CDC is the steward of health for the U.S., the building and design community is the steward for health in the built environment. Architects and designers need to continue to examine the way design impacts and inspires people to improve buildings, communities and our health.
As wellness frameworks like Fitwel are established, we can begin to unravel the structural barriers to healthy environments, ultimately promoting gender equity, wellness, and engagement in every workplace. Liz York is chief sustainability officer and associate director for quality and sustainability for the CDC. Appointed as the first CSO for CDC in 2008, York establishes sustainability in CDC policy and operations, implements healthy and sustainable work environments, and facilitates staff involvement in sustainability efforts. In 2016, she was recognized by the AIA as a Fellow for her work to impact health and well-being by empowering architects to build better environments.

for a few thousand dollars—a bargain compared to losing a valued employee. At CDC, my office works to translate science into action in other ways, too. Another example is FitwelSM (Facility Innovations Toward Wellness Environmental Leadership). This health-focused facility rating system was developed with the General Services Administration (GSA) and the New York City Department of Health and Mental Hygiene (DOHMH) to give strategies for building healthier buildings. Over five years, CDC, GSA, and DOHMH reviewed more than 3,000 research studies and consulted with public health experts and designers to craft this voluntary national certification. Fitwel assesses the healthiness of building environments and offers ways to improve building occupants’ health and wellness. As the nation’s public health agency, CDC promotes breastfeeding as important for human nutrition and general health. Our job as architects is to assess the built environment and adjust it to create buildings that protect the health, safety, and welfare of occupants. CDC’s lactation support program began in 1996 with one lactation room in Atlanta. Today, the program offers 34 lactation rooms at 13 campuses, and more than 4,000 staff have used the program. The rooms include a Medela pump, table, comfortable chair, footstool, towels, and a sign-in sheet. Most importantly, working moms have a quiet, private place, free from interruption.
Reducing Energy in Big Buildings 5 ways to gain wide support to reduce energy where you work
Alan Eber Gundersen Health System
Using less energy in large buildings may seem like a daunting challenge, but much of the challenge can be eliminated. I know firsthand what’s possible, as Gundersen Health System has adapted to reduce energy usage in our own facilities. In 2014, Gundersen became the first health system in the nation to achieve energy independence. Little or no support from management is a big obstacle facing many health care organizations that want to reduce energy usage. On my visits to such places, I often see a tendency to sell energy efficiency efforts based on money savings alone. The problem is that the C-suite often weighs options for money when they may not understand the return on investment. HOW TO GET C-SUITE SUPPORT
One of the ways Gundersen and others have gained support for energy reduction projects is by linking it to the organizational mission. At Gundersen, it’s straightforward. Our mission is to improve the health gb&d
and well-being of our communities. Reducing how much fossil fuel we use directly benefits the air quality in our region as well as lowers the cost of providing health care to our patients. Most organizations have missions around reducing waste, improving efficiency, or implementing the values of customers and staff. It’s easy to associate energy reduction with any of those criteria. Once the link to the mission is made, the C-suite will be more inclined to support the efforts. Once the groundwork for organizational support has been laid, it is easier to get started. The process Gundersen uses is an adaptation from the Six Sigma DMAIC (Define, Measure, Analyze, Implement, Control) process. GUNDERSEN’S KEY STEPS
BASELINE THE BUILDING(S). One
difference between the DMAIC process and our energy reduction process is this: We measure our buildings before we set goals. It is important to understand how much energy your building is using and compare that to similar buildings. This can be as simple as tracking the energy bills. If the building is very good compared to the benchmarks, it may be difficult or expensive to reduce the energy usage in the building. On the contrary, if high energy usage against the benchmark is found, one can be more aggressive setting energy reduction goals.
DEFINE GOAL(S). The
next step is to define smart goals for what you’re trying to achieve. Make sure the goals are specific and can
be measured not only when finished, but as the energy reducing efforts are ongoing. This will help to keep the stakeholders engaged. Goals should be aggressive but achievable. At the end, real accomplishment should be made, but don’t let yourself fall short due to unrealistic goals. The goal should also be relevant, meaning it drives the actions you would like to see. And it should be time-sensitive to drive aggressive action. Nothing will stop engagement like a goal that takes too long to accomplish. Too many issues can arise over time to wane enthusiasm.
IDENTIFY & PRIORITIZE OPPORTUNITIES. Then
it’s time to identify and prioritize the opportunities. We have helped many facilities through this process by performing energy audits in their buildings. This is a focused investigation of the building using experienced staff, engineers, contractors, and facilitators to identify wasted energy. We look for areas where excessive energy is being used, used when not needed, or being wasted or used in non-value added ways. If you work in a large facility, chances are you have plenty of opportunities for energy waste— including computers, projectors, lights, and HVAC systems that are left on even when the space is not occupied. Also, most large buildings have Building Automation Systems where the HVAC controls can be modified to help eliminate waste. Once you’ve made a list of opportunities, they must be prioritized. The building owner should develop criteria for prioritization. We use total energy saved, project payback, initial
capital cost, age of equipment being replaced, improvement in comfort, and reduced maintenance cost.
IMPLEMENT & MEASURE PROGRESS. After the
energy conservation measures are prioritized, it’s time to implement. This takes planning and coordination, and it can cause significant disruptions to the operations in the building. It is important to measure and share progress early and often. Because of the effort and disruptions, people may lose interest in the goal. Seeing progress helps fuel the fire to achieve the end goal.
Finally, once the goal is achieved, it’s important to celebrate. The more you share and celebrate the success, the more your organization will trust you to take on the next challenge.
Alan Eber is the manager of facility operations, engineering & energy for Gundersen Health System in La Crosse, Wisconsin. Gundersen began testing how much energy a building uses for a given size when it built its 427,000-square-foot Legacy Building with a goal of achieving 115 kBtu per square foot per year, below half of what the average hospital uses.

answers are fed back to the participants in a useful form. With constructive facilitation you have permission—and you must get permission!—to question, synthesize, and contribute. This goes beyond making sure everyone is heard. It is more directive, takes some courage, and definitely takes a good sense of humor.
So what is it? With one regional green building organization I worked with, the challenge was getting its local chapters more engaged and working together. QUESTION

Most green building professionals understand the benefit of approaching design solutions collaboratively. Healthy collaboration is inclusive; it starts with the basic assumption that everyone in the room has something significant to contribute and something to learn. In my book, EMERGE: A Strategic Leadership Model for the Sustainable Building Community, this definition of collaboration is just the starting point. With “emergent” collaboration, emphasis is on the process being transformative for both the participants and the situation itself. There are multiple techniques for achieving this, but an important one is “constructive facilitation.” Typically the role of the facilitator is to elicit contributions to a discussion of an agreed upon question or set of questions, making sure this input is recorded and then assuring that these

a smart grid you know how much your solar panels are producing versus how much you have stored in batteries.

Question, synthesize, and contribute. I kept bringing the conversation back to: Why weren’t the chapters motivated to be engaged in the first place? Why didn’t they see themselves in the larger picture? What would it look like if they did?
synthesize, and contribute to the discussion in any meaningful way. As a “constructive” facilitator, you will be able to model positive and meaningful contributions, enhancing the chances of a productive discussion.
gb&d: How does all that connect to the built environment? Sarda: You can think of the old version of the grid as like an incandescent bulb in a light fixture with a switch that turns it on or off—it’s pretty much as analog as you can get. Whereas now we have all of these lighting systems in smart offices that know whether you’re at your desk or not or what time of day it is and how much the sun is shining in from outside, and they can automatically adjust the amount of electric lighting based on the amount of ambient lighting available. So that’s not nearly as analog as the light switch that just turns the light on or off.
This means stopping from time to time to review input and state what you think the group as a whole is expressing. Your syntheses should be as inclusive as possible and not just reflect the best idea (in your opinion) being put forth. The group may correct your interpretation, and that’s fine. At times in the above regional group example, my syntheses of the previous 20-minute discussion elicited a “Yes! That’s what we mean!” At times it was a “No! Let’s talk about this some more!” In addition to providing clarity and improving the chances of productivity, this exercise encourages the group to think consensually.
Kathleen O’Brien brings 30-plus years as an award-winning educator, writer, strategic planner, and project consultant in the green building field to The EMERGE Leadership Project, a 501c3 nonprofit she founded to build leadership capacity within the sustainable building community. The project’s ultimate goal is to “accelerate the adoption of lifesustaining solutions in the built environment through emergent leadership.” EMERGE: A Strategic Leadership Model for the Sustainable Building Community is her second book; her first book, The Northwest Green Home Primer, was published in 2008.

Any good facilitator should practice discovery. Prior to the event, I conduct an online survey; barring that, I interview key individuals in the group. I am also a strong proponent of using facilitators with content knowledge.

Person of Interest Lynnette Tedder
gb&d: What are the biggest challenges facing health care design today? Tedder: The constant change in a culture that is not used to changing quickly. The way care is delivered is finally moving forward, but there are many ways it doesn’t move. The design of facilities needs to be progressive, forward-thinking, and flexible. Helping the client and caregivers to see how the built environment can facilitate this is not always easy, but I see more awareness and open minds coming forward.
“Keep focusing on beautiful, inspiring spaces.” Interview by Laura Rote
Lynnette Tedder has been designing interiors in the health care industry for more than 20 years. “I have been in the industry a long time and ended up gravitating toward health care because of the size and complexity of the projects,” she says, adding that the nature of the projects and their clients keep her interested. “The clients are people who are in a caring industry. It’s a business, yes, but they are compassionate and caring about the people they serve. And most of all, I can really make a difference in the experience of both patients and staff. It’s emotionally rewarding.” Currently a senior project designer for Perkins+Will in Los Angeles, Tedder serves as a health care interiors liaison to a national health care group and leads a health care forum in L.A. She has worked on corporate, commercial, retail, hospitality, and
gb&d: How does the world of sustainability intersect with health care? Tedder: It’s critical. Healthy materials make sense especially in this environment. Thankfully Perkins + Will has been on the forefront of research of these materials and has made great progress in helping manufacturers list their ingredients to help inform the right uses. It is easy to utilize appropriate finishes in many ways, but the flooring is still a huge challenge. There are some areas where seamless flooring is required, yet the products available are so limited due to the chemical makeup. High performance is critical and so many that do perform have toxic materials in their makeup. Manufacturers are working hard to find the right solutions, but there is a ways to go. gb&d: What is the most important thing to consider when designing a health center? Tedder: I focus on the patient experience. This entails so many aspects of the physical environment, the approach, ease of navigating the
space, the overall aesthetic and brand, and amenities in addition to the care provided. Keeping all stakeholders involved in the design is critical and makes for a very well thought out facility. gb&d: Do you have a favorite project you’ve been involved in? And if so, what stands out to you about that project? Tedder: One of the most enjoyable projects I worked on was a new tower for St. Joseph’s Hospital and Medical Center in Phoenix, Arizona. It was a favorite in that I worked on the planning, design, furniture, and artwork holistically and was able to commission art specifically to support our concepts of design. It was an ideal collaboration of administrators, nursing, facilities, and patient advocates and community and was so fun to do. It was early in the concepts of designing for staff support as well as patients and we were able to really provide amenities for staff respite and recharging. It was a whole design, start to finish. gb&d: What is the biggest learning curve with regard to designing truly healthy spaces? Tedder: Healthy materials that also hold up to the high demands of cleanability while still providing a beautiful and comfortable aesthetic. It takes a lot of time and experience to understand what the cleaning products can do to materials. Not all staff use only products that are approved by facilities. Infection control is a huge topic of concern and liability, yet protocols are not always followed. Designers need to plan for the worst in selecting appropriate products and materials. gb&d: How does approaching the design of a health care facility today differ from, say, 20 years ago? Tedder: So much more connection to nature, so much more integration of natural light and views, the gbdmagazine.com

Tedder: Nature views, natural light, air, and space lift the spirit and help the body heal itself. The color palette of natural elements proves timeless and provides a sense of a calm and well designed space that promotes healing. gb&d: What effect does exposure to natural spaces have on patients? Tedder: Just the “feel good” aspects of being in natural environments lifts the spirits. There is a sense of empowerment that comes in a natural environment. You can get better or at least take a better approach to your medical situation. gb&d: What about all of that artificial light in hospitals? Tedder: I love the direction the industry has taken to use natural light as much as possible and, where not, provide lighting gb&d
The St. Joseph’s Hospital and Medical Center in Phoenix is an example of holistic design that Tedder was excited to work on.
Sarda: We have very aggressive science-based targets for climate goals and carbon reduction. We were actually one of the first companies in any sector, and certainly the first in our sector, to set science-based targets. We’ve been disclosing our environmental impact for years now. We recognize that climate change is real and needs to be addressed, and we believe business has a role to play. We also see it as meeting the needs of our customers who clearly want a more efficient, cleaner energy future. gb&d: What are your thoughts on the impact of the Trump administration on clean energy?
that is more indirect or provides the ability to control circadian rhythms. gb&d: What are some concepts you wish everyone would implement in health care facilities? Tedder: Keep focusing on beautiful, inspiring spaces. Just because there are clinical restrictions the environment does not need to be cold or utilitarian. Keep the appropriate focus on texture and patterns, color and contrast and keep palettes natural and timeless. I hate seeing overly colored environments or those with too much going on. Keep it calm and lovely and balanced. gb&d: What’s one thing people don’t realize with regard to the design of health care facilities? Tedder: How integral the design is to the daily experience for staff as well as patients and visitors. Good design resonates as just a lovely space, not overly gimmicked. Keep it easily navigated and simple. gb&d
Sarda: Obviously there are lots of questions that have not been answered yet, and I certainly can’t speculate as to what the future will look like. What we do believe, however, is the transition to renewables is now so far underway that I don’t think the federal government will have nearly as big a lever as it used to have in shaping the future. The economics of renewables now are more and more favorable, and the demand is very strong. gb&d: What sparked you to get involved with sustainability education at ASU? Sarda: I originally went to ASU as an undergrad. ASU has the number one degree-granting sustainability school in the country. And it’s not just a leading institution for sustainability education, but for research and outreach and integration across the whole institution. They have sustainability embedded all across the organization. gb&d: What’s the thinking behind the Executive Master of Sustainability Leadership This conversation continues on p. 81

Our message to all of our customers, and future customers, is: How you buy your power matters. If you want a sustainable energy future, ask for it, and advocate for it.
MOST MEANINGFUL PROJECT YOU’VE COMPLETED:
Helped design and build exec master’s program for sustainability leadership at Arizona State University
MOST COMMON GREEN MYTH: We can’t afford to be
ONE QUESTION INDUSTRY PROFESSIONALS SHOULD ALWAYS ASK THEMSELVES:
politics out of it. Make it about health, security, and prosperity for all.
Are we measuring outputs or outcomes?
THE BOLDEST IDEA IN SUSTAINABLE DESIGN:
PUBLICATION YOU HOPE WILL NEVER DIE: National
Growing infrastructure instead of building it
Sarda: I developed a workshop that became a course on how to prepare for career success in sustainability, based on the premise that knowing what sustainability is is important, but that it’s a small part of what success looks like. Success looks like helping people and organizations navigate through disruptive, ambiguous, difficult, uncomfortable changes. How do you make the case for that? How do you inspire? Going back to the Cousteau model, how do you not make people do things, but make them want to do things?
