DPR Construction set out to build an office that showcases ideas for green design after realizing it was hard to sell clients on green design concepts without providing viable proof.

TKWA’s addition to the Frank Lloyd Wrightdesigned Meeting House maintains the integrity of the original design, provides space for daily needs and aligns construction with its deeply held environmental values.

The NGRREC provides scientific resources and public outreach related to improving the sustainable management of large rivers while mimicking the Mississippi river bluffs.

Idea House was conceived as a test bed for new ideas in sustainable architecture within a tropical setting. The house is targeted to be a carbon-neutral residence, believed to be the first in Southeast Asia.

EDITOR’S

NOTE

Dog Days of Employment Searching

It was a different time when I participated in my first LEED Guide back in 2007. The U.S. housing bubble had yet to burst, and business was booming for many architects and contractors focused on sustainability. When that bubble did burst, it combined with additional economic factors and dragged the U.S. into a recession. Construction projects began drying up. Employers began laying off employees, and the number of people out of a job began rivaling the worst economic times in U.S. history — even in the green sector. Whether you agree with the action or not, the government eventually stepped in with the American Recovery and Reinvestment Act of 2009. Part of this act was designed to create new jobs and save existing ones through government investment in energy and the environment in addition to tax benefits for home energy efficiency improvements and tax credits for alternative energy equipment. Based on where the money was supposed to go, it made sense that readers of ED+C would see, directly or indirectly, an improvement in employment opportunities. And many readers did — but many didn’t. Hearing from a reader describing his or her trouble finding a job is difficult, especially when they’re looking to you to help them find answers. So, we wanted to provide our readers with the answers they were looking for. Being a publication, doing an article about finding a job and where all the funding for jobs was heading was a natural fit. Our staff began collecting everything it could find regarding the job situation. In the end, we realized, there was no magic bullet, single-answer solution regarding where the jobs were. (Well, actually, there was an answer: service industry. But, we figured our audience wasn’t interested in those types of jobs.) In our opinion, a reader’s job search came down to a caseby-case basis.

The Perfect Fit Maybe not surprisingly, our publication’s readers weren’t the only ones feeling the employment crunch. Readers of many of the A/E/C publications at ED+C’s parent company, BNP Media, were having the same troubles. Like ED+C, these other publications came to the same conclusion. That’s why BNP Media partnered with BirdDog Career Centers. During its 14-year history, BirdDog has helped more than 3,500 employers in specialized industries move to a strategy of planned hiring. In addition, the combined BirdDog family of sites and solutions has attracted more than 100,000 job seekers. “We are excited to partner with BirdDog to provide job placement and career counseling solutions for our markets,” said BNP Media Publishing Director Tim Fausch. “Many of our markets are rebounding from hard times. This new career center allows us to help strengthen the architectural, design, engineering, construction, sheet metal, facilities and data center management markets by matching employers with ideal employees.” Companies seeking employees or job seekers can access the Career Center by clicking on the BNP/BirdDog widget found on the home page of www.EDCmag.com. We at ED+C don’t want to get back to the level of employment in 2007: We want the employment level of our readers to be better than back then. Given the optimized nature of BirdDog’s Career Center in matching qualified candidates with the right company, we feel it’s entirely possible to surpass even our expectations. Cheers,

Having trouble figuring out which wall protection is safest for the environment?

That’s because most manufacturers are making environmental claims designed to confuse you. Not us. Acrovyn® 4000 contains no PVC, PBTs, or any other harmful chemicals—and we can prove it! Acrovyn® 4000 is the only wall protection that’s MBDC Gold or Silver Certified, so you can be sure it’s the healthiest product available. Other companies don’t disclose what chemicals their products contain. So if protecting people is as important as protecting walls, choose Acrovyn®.

A Fresh Take on the LEED Guide EVERY ARTICLE IN THE LEED GUIDE HIGHLIGHTS

A LETTER FROM RICK FEDRIZZI.

A NEW ASPECT TO LEED AND USGBC.

ed+c

J U LY 1 1

Since its inception, LEED has been at the forefront of the green building industry, pushing those new to green building to adopt sustainable practices and encouraging tried-and-true experts to bring their specialties to the table. LEED, and its community of implementers and supporters, has always been cutting-edge. But now more than ever, LEED and the U.S. Green Building Council are evolving in ways we only dreamed possible at the beginning of our journey: technology tools to enhance LEED’s functionality, international partners and mainstream adoption in nearly every building sector. This year’s LEED Guide highlights what’s next for LEED. In a changing and growing industry, it must continually adapt in order to provide the most current and complete benchmarks for green building. The development of LEED 2012 and the launch of the LEED Volume Program represent two cornerstone initiatives in our efforts to keep LEED’s offerings current. On top of that, we work to bring industry professionals and project teams the best possible resources for achieving LEED certification. New technology-based tools that support LEED will help spread green building knowledge and certification assistance as fast as a Wi-Fi connection: The LEED for Homes Scoring tool allows green building newcomers as well as experts to rapidly assess their projects. Our Green Building Information Gateway (GBIG) brings the global stock of efficient buildings into a point-and-click perspective. USGBC’s Building Performance Partnership (BPP) uses technology to gather and monitor building

performance and suggest improvements. While high-tech tools are crucial to LEED’s evolution, USGBC is quickly growing far beyond the confines of computer screens. On the global stage, USGBC collaborates with 19 other countries on the LEED International Roundtable. Customer service is now offered in Spanish and soon, Chinese. LEED professional credential exams are available in French. Two LEED-certified schools are in the works in Beijing and Changsha, China, and USGBC is working to expand LEED for Homes pilot programs internationally. These global strides are crucial to the future development of LEED and for the broader goal of greening not just our country, but also our world. Last year, Greenbuild, USGBC’s annual conference, showcased our growing international presence, drawing attendees from an impressive 114 countries. To celebrate the international green building movement, this year’s Greenbuild NEXT is based in Toronto, one of the most cosmopolitan and innovative global cities in the world. As the name suggests, Greenbuild NEXT will usher in a new era of green building. These improvements are just the tip of the iceberg. Every article in the LEED Guide highlights a new aspect to LEED and USGBC. One thing that hasn’t changed is USGBC’s mission: to green the world’s building stock to reduce environmental impact and enhance the lives of people everywhere. While USGBC is celebrating our founding vision in new and more exciting ways than ever, we stay grounded and united behind our goal to enact monumental change in the built environment. It’s the motivation pulsing through every USGBC program. I applaud the green building community for its commitment to this noble cause, and I thank you for inspiring USGBC’s new initiatives with your own innovation and passion. Please reach out with your suggestions and comments on our evolving programs. I’m active on Twitter and would love to get your feedback: @RickFedrizzi. My excitement about the evolution of LEED and green building is eclipsed only by what will come next. Stay tuned!

Helping to Grow LEED USGBC MEMBERS ARE CENTRAL TO THE COUNCIL’S MISSION OF TRANSFORMING THE WAY BUILDINGS AND COMMUNITIES ARE DESIGNED. As the green building industry grows, evolves and prospers, the U.S. Green Building Council has remained true to its mission — to transform the way buildings and communities are designed, constructed, operated and maintained, enabling an environmentally and socially responsible, healthy and prosperous environment that improves the quality of life. And central to realizing this mission is the USGBC member community.

This community of dedicated member organizations and their employees, green building leaders and volunteers is at the core of everything USGBC does, from expanding the LEED rating systems and education, to the Greenbuild Conference and Expo, to the Center for Green Schools at USGBC. They are a part of every building that achieves LEED certification, every milestone we reach and the continued growth and evolution of our industry.

As a community, we’ve celebrated tremendous growth during a time when odds were stacked against our industry. In 2010, we observed the 10th anniversary of the launch of the LEED rating system. Since its initial launch, through the consensus-based approach taken by members, LEED has evolved to include rating systems for existing buildings, schools, healthcare and neighborhood development. This suite of rating systems culminated this year in achievements once unimaginable — more than one billion square feet of LEED-certified space and more than 100,000 registered and certified projects around the world. With member support, the Center for Green Schools launched in 2010, along with the promise of sustainable learning environments for all students within a generation. Because of member feedback, new tools have been developed for green building practitioners to utilize as they implement LEED in projects.

Keeping Up GROWTH OPPORTUNITIES FOR LEED APS: SPECIALTY CREDENTIALS IN THE GREEN BUILDING MARKETPLACE.

AS LEED AND THE GREEN BUILDING INDUSTRY CONTINUE TO EVOLVE AT A RAPID PACE, THEY MUST BE SUPPORTED BY A GLOBAL COMMUNIT Y COMMITTED TO MARKET TRANSFORMATION.

ed+c

J U LY 1 1

This year, the global footprint of LEED-registered and certified projects surpassed eight billion square feet. Technological and scientific innovation, increased resources and wider consumer acceptance have resulted in a sophisticated and dynamic industry that continues to advance at a rapid pace. Increasing adoption of LEED has amplified the demand for professionals who understand the LEED rating system. In 2009, GBCI introduced a new suite of LEED Credentials that recognize the necessity of keeping up with the swift progression of the green building industry: the LEED Green Associate and five LEED AP with specialty credentials. To date, more than166,000 individuals hold a LEED AP, LEED AP with specialty or LEED Green Associate credential. The LEED AP with specialty credentials allow professionals to demonstrate their expertise in related fields: building design and construction; interior design and construction; operations and maintenance; homes and neighborhood development. The credentials are maintained through continuing education on a two-year cycle, which ensures that LEED Professionals keep up with green building innovation, current standards and practices and the continuous evolution of the LEED rating system. For LEED APs who tested between 2001 and 2009, GBCI has provided a limited window of time during which these current LEED APs can sign up to add a specialty to their credential. After enrolling, they will have two years to complete 30 hours of relevant

continuing education activities within their specialized field. The individual deadlines to enroll in this program end between Aug. 7 and Oct. 27 of this year. The LEED Green Associate was created for professionals in a variety of fields involved in green building, including students, real estate professionals, journalists, attorneys and a host of other professions. The LEED Green Associate demonstrates credibility in green building and a baseline of knowledge of green and LEED. The LEED Green Associate credential is a mark of recognition for professionals who may not have direct involvement on a LEED project but who work closely with the sustainable building industry in other capacities. The credential is maintained with 15 hours of continuing education every two years. The LEED AP with specialty credentials consist of the LEED AP Building Design + Construction, LEED AP Interior Design + Construction, LEED AP Operations + Maintenance, LEED AP Homes and LEED AP Neighborhood Development designations. These credentials are the marks of the most qualified green building professionals in the marketplace and demonstrate particular expertise in these five specializations within green building. The specialty credentials are maintained with 30 hours of continuing education every two years. The continuing education requirement guarantees that credential holders are exposed to the most current industry information and are equipped to apply that knowledge to their work. GBCI developed the Credential Maintenance Program (CMP) as a

way to help LEED credential holders keep current while providing easy access to existing continuing education opportunities. The variety of ways to earn required hours makes the process of maintaining the LEED credential flexible, personal and meaningful to the credential holder’s professional goals. This fall, GBCI will announce its first class of LEED Fellows, its newest and most prestigious designation. LEED Fellows are the world’s most distinguished green building professionals. Nominated by their peers, LEED Fellows are selected based on their body of work and their contribution to advancing the industry. Among other eligibility requirements, both candidates and nominators must hold the LEED AP with specialty credential or enroll to add the specialty before their fall 2011 deadline. As LEED and the green building industry continue to evolve at a rapid pace, they must be supported by a global community committed to market transformation. LEED Professionals have proven themselves to be the movement’s most visionary in thought, innovative in design and tireless in determination. As they grow in education and experience, they will continue to play an even stronger role in raising the bar and making greater strides in green building achievement around the world.

The Tech Side of LEED QUICK, EASY AND FREE PROGRAMS ARE GIVING AN EVER-GROWING NUMBER OF PEOPLE ACCESS TO LEED.

Technology is essential to green building. While sustainability is rooted in basic concepts, such as conserving resources and creating healthier indoor environments, it is often technology that helps accomplish these goals. Computer and tech-based tools have proved instrumental to the development and dispersion of LEED. The launch of LEED Online brought certification tools to the fingertips of project managers, and the U.S. Green Building Council’s (USGBC) suite of online learning resources offer up green building knowledge at the click of a mouse. Three new technologybased offerings, the LEED for Homes Scoring Tool, the Green Building Information Gateway (GBIG) and the Building Performance Partnership (BPP), represent exciting new initiatives that will expand on USGBC’s tech-side efforts. Deployed in March of this year, the LEED for Homes Scoring Tool offers anyone at any level a simple and free way to explore the LEED for Homes program (www.leedforhomes.org). The tool’s main function is to give users a realistic idea of where their project stands in the realm of LEED certification: which green features and building strategies will push a project to a specific level of certification, and how to get there. The QuickScore path offers a rapid evaluation of any project, and the deeper Credit by Credit path allows any project team member the opportunity to explore which green features they want to incorporate. Many users find that they are much closer to LEED certification than they thought, and that the path to certification is simple and straightforward. To date, around 4,000 people have accessed the LEED for Homes tool to evaluate their project. The high level of interest reflects a major milestone that LEED for Homes hit in March of this year: 10,000 LEED-certified homes. With the rapid growth of residential green building and certified projects, the LEED for Homes tool is more relevant than ever.

Green Building Information Gateway (GBIG) is not a single program or tool, but rather a family of resources. While many aspects of GBIG are still evolving and in development stages, it will ultimately consist of a suite of tools and apps that will make green building stats, from specific project information to regional climate zone data (and much in between), accessible in a variety of ways. The best part? It’s free. GBIG Analyst, a benchmarking tool that’s currently available on the Web, displays green buildings on a navigable map of the U.S. Users can access performance metrics for buildings and compare projects based on LEED credit achievement. The mobile app version allows users to keep this handy data in their back pockets — literally. A new app, Explorer Place, summarizes green building activity in a given area, allowing users to make comparisons between counties, cities, states and more. The data available on this app goes beyond singular buildings: The app tracks policies and a variety of other green building indicators, culminating in a green building score for geographic areas. Visit GBIG.org for more information, or visit the App Store on Apple.com to download GBIG Analyst. Building Performance Partnership (BPP), a free building performance tracking and reporting program, is currently an optional leadership tool for LEED-certified projects. USGBC works directly with projects to collect performance data, offering participating projects annual feedback on building performance. Through basic analysis, strategies to optimize performance per building can be identified and implemented. Perhaps most importantly, BPP fosters a partnership between USGBC and the community of thousands of LEED project owners. USGBC will apply the performance data collected from BPP to populate a comprehensive green building performance database, enabling standardization of reporting metrics and analytics as well as establishing new performance benchmarks. BPP will be integral in LEED’s evolution. Visit USGBC.org/BPP for more information on the Building Performance Partnership.

LEED has marched steadily into virtually every corner of the institutional, commercial and industrial facility sector. Its various iterations have gone far toward generating industry-wide awareness and acceptance of green design, operations and maintenance. Released in April 2009, LEED 3.0, also called LEED v3 and LEED 2009, raises the bar relative to previous specifications by, for example, requiring a 10 percent energy reduction versus ASHRAE 90.1-2007 for new buildings, as well as an ENERGY STAR performance rating of at least 69 for existing facilities. Metering, alternative energy use, commissioning and other energy-efficiency strategies that reduce carbon-dioxide emissions are also weighted more significantly in LEED 2009. In the latest spec for Existing Buildings: Operations & Management (EBOM), for example, facilities can obtain up to six points for renewable energy use as opposed to only four under the previous LEED 2.2 version. Likewise in LEED 3.0, available credits for Water Efficiency and Energy & Atmosphere have seen dramatic increases of almost 67 and 106 percent, respectively, versus LEED 2.2. Figure 1 illustrates the many credit categories in which submeters can contribute points for LEED certification ratings in Schools, EBOM, New Construction (NC), Retail NC, Commercial Interiors (CI), Retail CI, Core & Shell (CS) and Healthcare. Another key difference in terms of credit requirements in LEED 3.0 for New Construction is a 20 percent reduction of in-building water use that is now required â&#x20AC;&#x201D;

cuits of interest. In post-certification scenarios, for instance, metering provides an ongoing hedge against losing visibility on potential energy savings due to staff changes, equipment replacement, shifting utility rate structures and other changes in the facility’s operational dynamics. As a scalable, easily installed data acquisition solution to help identify energy savings over the course of the facility’s entire operational lifetime, submeters more than justify their initial installed cost.

The energy section offers some of the 3.0 specification’s most targeted guidelines for decreasing energy consumption and increasing alternative energy use. It also provides guidance on commissioning so that facility executives can be sure their systems are functioning at peak efficiency. The backbone of the measurement and verification (M&V) process required for LEED certification at every level is the electric submeter. As shown in the table, the primary building performance category in which submetering plays a key role is the

Energy & Atmosphere (EA) subset that runs all of the major assessment categories, including Schools, EBOM, NC, Healthcare and others. Another important LEED 3.0 change occurred in the rating system itself. Credits have been realigned along a 100-point scale that allows six more points for innovation and four for the newly added regional priority subcategory. In LEED 3.0, certification levels are based on: 40-49, Certified; 50-59, Silver; 60-79, Gold; 80 or above, Platinum.

LEED certification was created in 2000 by the U.S. Green Building Council (USGBC) to provide third-party verification of a building’s sustainable features. Beginning with commercial buildings and ultimately expanding coverage to a variety of industries, from homes to healthcare facilities, LEED was designed to green the built environment one building project at a time. But what about organizations seeking to green many of their structures — or their entire building stock? Cue the LEED Volume Program, developed for organizations and companies that are large users of LEED. The Volume Program leverages uniformity in design to offer a cost-effective method of certifying a large number of buildings while preserving the integrity of LEED benchmarks and standards. Instead of undergoing certification at a per-building rate, the LEED Volume Program offers organizations the option to first create a prototype, which, upon precertification, can be applied to certify like buildings and spaces throughout their building portfolios. Since the program is based on design uniformity, like buildings in any geographic area are eligible for certification, whether they are 100 feet apart or 1000 miles. By simplifying LEED documentation, the Volume Program provides a cost-effective, timesaving and ultimately streamlined approach for organizations to incorporate highperformance buildings across their entire building stock. The LEED Volume Program was conceptualized in 2006 and officially launched at USGBC Greenbuild 2010 Conference and Expo in Chicago to a strong industry response. The program is currently available for Design + Construction projects, and the LEED Volume Program for Existing Buildings was unrolled at the Building Owners and Managers Association (BOMA) International Conference at the end of June 2011. To date, participants in the LEED Volume Program include Verizon Wireless, Kohl’s, McDonald’s, the InterContinental Hotels Group (IHG) and more. Here’s how it works: Interested organizations begin by applying to USGBC to use the LEED Volume Program. Once accepted, they gain access to a variety of services and online tools that facilitate prototype de-

velopment, including account management services, USGBC education resources, an orientation program and other applicable tools. Next step: Creation of a prototype. The prototype itself is not a building or material project, but a design scheme: a mock-up and plan for forthcoming volume projects to adhere, mapping out sustainable design features and protocol. Once the prototype is reviewed and approved by the Green Building Certification Institute (GBCI), the applicant may begin work on all volume projects. Since the program is geared toward large-scale users of LEED, per-project certification costs drop significantly as the quantity of volume projects increases. To ensure these projects keep with LEED rigor, GBCI conducts random audits of a percentage of the organization’s volume projects. This third and final phase of the LEED Volume Program is called “ongoing certification” for this reason. The LEED Volume Program underscores USGBC’s commitment to provide smart solutions for large users of LEED. The impacts and advantages are far-reaching. Organizations that participate in the LEED Volume Program reap the repertoire of green building benefits across their portfolio: betterperforming buildings that save money, reduce harm to the environment and appeal to environmentally conscious tenants and customers. With the LEED Volume Program’s streamlined certification process, organizations can achieve this at lower per-project certification costs, all without compromising the technical rigor of LEED. On a broader scale, the LEED Volume Program accelerates the process of bringing sustainable structures to our organizations, companies and communities; benefiting the environment, building occupants and communities as a whole. It’s a win-win for volume participants, and an illustration of how LEED offers innovative implementation strategies that can benefit an organization’s bottom line.

Cheat Sheets THE CENTER OF GREEN SCHOOLS OFFERS A NUMBER OF STUDY AIDS TO HELP PROFESSIONALS PASS THEIR NEXT GREEN SCHOOL TEST. The U.S. Green Building Council launched the Center for Green Schools at USGBC in 2010 to help green our schools. The center’s vision is a bold one: green schools for everyone within this generation. Approximately 25 percent of our national population goes to school every day. There are currently more than 2,000 LEED registered or certified K-12 schools throughout the United States and more than 4,000 LEED registered or certified buildings on college and university campuses. Great strides have been made in green building, and government initiatives such as the Department of Education’s Green Ribbon Schools program are elevating the issue for K-12 schools. However, there are more than 133,000 schools and 83,000 college buildings across the country, which leaves much work to be done. Green schools reduce energy consumption, save money and, most importantly, foster healthier learning environments for students and educators. Much of the focus on green building has been on new construction. However, the Center for Green Schools at USGBC is also offering support to educational leaders looking to enhance the performance of their existing buildings and infrastructure — with the understanding that the people who build, retrofit and operate these buildings are at the core of achieving high-performing and healthy educational spaces. The Center for Green Schools at USGBC has developed an array of resources to help guide professionals in the greening of existing buildings:

The resource provides detailed information on how to aggregate green improvement measures to optimize project economics and achieve LEED-EBOM certification. In addition, two resources have been created for colleges and universities: 1. The Roadmap to a Green Campus is a strategy guide for using the LEED green building certification program as a framework for developing and evolving campus-wide sustainability plans. Contained within the 100-plus page document are more than 100 tools and resources to support campuses in their greening efforts and more than 20 unique profiles of college and university success stories. The guide was

created with the support of the Association for the Advancement of Sustainability in Higher Education (AASHE). 2. Hands-On LEED: Guiding College Student Engagement is a document that speaks exclusively about the role students can play supporting green building projects and how they can contribute to LEED certification efforts. The guide outlines three options for engaging students: coursework, internships and volunteer opportunities. It details the benefits of involving students and outlines ways to initiate the process of developing an engagement program. The center also offers a variety of additional programs and resources that are supported in part through financial contributions, grants and partnerships, including a multi-year, multimillion-dollar financial commitment from the center’s first founding sponsor, United Technologies Corp. While the Center for Green Schools at USGBC engages various groups of leaders who want to make a difference, we have only just begun to scratch the surface. From the kindergartner entering the classroom, to the Ph.D. student performing research in a lab — the center believes that everyone deserves to attend a green school within this generation.

Accountability and Performance THOSE WHO FOLLOW THROUGH WITH THEIR COMMITMENT TO HIGH-PERFORMANCE BUILDING ARE HELPING TO CREATE BETTER BUILDNGS.

BY HOLDING THEM ACCOUNTABLE, THESE PARTNERS WILL COMMIT TO A SERIES OF ACTIONS TO MAKE THEIR FACILITIES MORE EFFICIENT AND HIGH PERFORMING.

ed+c

J U LY 1 1

What do LEED, the White House’s newly launched Better Buildings Initiative (BBI) and USGBC’s Building Performance Partnership (BPP) have in common? Accountability and performance. In February 2011, President Obama announced the Better Buildings Initiative, which seeks to cut energy consumption in commercial buildings by 20 percent while saving businesses $40 billion per year. Most of the $1.2 trillion energy-efficiency opportunity is in buildings, and the bigger the building, the larger the opportunity to save energy.1 The president is challenging CEOs and university presidents to make their organizations leaders in saving energy, which will save them money and improve productivity. By holding them accountable, these partners will commit to a series of actions to make their facilities more energy efficient and high performing. They will in turn become eligible for benefits including public recognition, technical assistance and best practices sharing through a network of peers. The U.S. Green Building Council’s (USGBC) member companies are already turning existing buildings into higher performing facilities through the LEED for Existing Buildings: Operations and Maintenance Rating System, which creates the infrastructure necessary for programs like BBI to be successful. During the last two decades, USGBC and its members have worked through LEED, the nation’s premier green building verification tool, to fulfill the mission of green buildings for everyone within a generation. LEED provides the

tools, accountability and verification for all aspects of green buildings, including energy efficiency. USGBC’s network of 16,000 member companies, 79 chapters and 166,000 LEED professional credential holders have been, and will continue to be, dedicated to better building operations. A better building isn’t just energy efficient; it’s also healthier and saves water and other resources. BBI’s focus on existing commercial building energy efficiency will lead to scores of more efficient buildings, and CEOs and university presidents demonstrate leadership by improving in other areas of sustainability and certifying through LEED-EBOM. USGBC’s BPP is a way for USGBC to collect the building performance data and capture feedback on LEED-certified projects. The performance data collected from BPP will be used to populate a comprehensive green building performance database, enabling standardization of reporting metrics and analytics,

as well as establishing new performance benchmarks that will help BBI in its success. Greater building efficiency can meet 85 percent of future U.S. demand for energy.2 A national commitment to green building has the potential to support 7.9 million American jobs, according to a 2009 study by Booz Allen Hamilton. By providing accountability and verification for green building performance through initiatives like LEED, BBI and BPP, we will drastically reduce resource consumption of our buildings and create a healthier environment for everyone.

Global Strides LEED INTERNATIONAL PROGRAM ADVANCES GREEN BUILDING AND GREEN BUILDING KNOWLEDGE ON A GLOBAL SCALE. Through the commitment and success of the U.S. Green Building Council (USGBC) member companies and LEED professionals, LEED has become one of the most well-known and widely used green building rating systems in the world, with projects in more than 110 countries and still growing. In 2010, USGBC created the LEED International Program, which supports members and professionals in the global community and advances the LEED rating system and surrounding programs to accommodate international outreach.

L EED L ANGUAGE ADVOCACY GREENBUILD

USGBC has applied the lessons learned from the LEED green building community in order to create the LEED International Program, with global consistency at its core. To support this, the LEED International Roundtable, made up of representatives from 20 countries, was created to work with USGBC to bring international perspectives by collaboratively identifying common non-country specific solutions to shared regional issues. Later this year, USGBC will also be releasing its first round of alternative compliance paths for LEED credits for projects outside the U.S. These alternative compliance paths will offer country-neutral options to reach the intent of specific LEED credits. Stay tuned for more information in the coming months.

Language Real change in the marketplace occurs when information is accessible to all. To advance this, USGBC customer service is now available in Spanish, and a Chinese-speaking customer service line will launch by 2012. In the same spirit, the LEED 101: Green Building Basics & LEED online course is also available in Spanish, and additional materials in Chinese, including a collection of project profiles and other basic resource materials, will be available by summer of 2011. Also new this year: The LEED AP and Green Associate exams are now available in French.

Advocacy USGBC and its community continue to lead in promoting green building legislation domestically, but also globally by participating in the World Green Building Council, the Conference of Parties (COP) and the United Nations Sustainable Building and Climate Initiative, among others. USGBCâ&#x20AC;&#x2122;s own Global Leadership in Our Built Environment (GLOBE) alliance brings together 50 partners from around the world in a call to action for the international community to invest in

J U LY 1 1

When the green building industry convenes at the U.S. Green Building Council’s Greenbuild International Conference and Expo each year, something special happens. A sense of purpose, community and hope abounds, reinforcing the importance of the work taken on by the green building movement. In 2010, Generation Green redefined the future in Chicago. This year, as Greenbuild celebrates its 10th anniversary, we look forward to what comes next. And as we travel down the path to what’s next, things are changing quickly. For the first time, the U.S. Green Building Council is taking Greenbuild outside the U.S., crossing the Canadian border and heading to Toronto, Oct. 4-7, 2011, for Greenbuild NEXT. Diverse, cosmopolitan and home to a growing number of registered and certified LEED buildings, Toronto represents what’s next in the international adoption of sustainable and green building practices. International communities are embracing LEED and green building at a staggering rate. Last year, attendees from 114 countries, totaling nearly 60 percent of the world’s countries, were represented at Greenbuild. Delegations from South America, Asia, Africa and beyond descended on Greenbuild to learn about what’s new and different in the building industry and how they can incorporate the knowledge gained through the conference and sustainable innovations and solutions found at the expo in the buildings in their native countries. And Greenbuild, as the world’s largest conference and

expo dedicated to green building, is the place where industry leaders and newcomers alike connect to learn about what’s new — and next — in green building practices, technology and innovation. The atmosphere at Greenbuild fosters an environment that encourages conversation and collaboration to come up with solutions for changing the status quo. In the exhibit hall, attendees meet face-to-face with the companies and organizations that supply the tools they need to create change and realize what’s next. PASSPORTS American citizens are required to provide a current passport for entry in Canada. Be sure to apply for or renew your passport now so you can see what’s NEXT at Greenbuild 2011!

Each year, the packed exhibit hall leaves both exhibitors and attendees with the renewed assurance that green means business — and Greenbuild is the place to do business. Information on innovative products and technologies is available to attendees, while exhibitors leave knowing that their products allow the building community to make sustainable choices. Both groups take away the understanding that utilizing green really does grow business. Conference attendees sharpen their competitive edge with the first-class educational content found in the sessions and summits. Greenbuild is the place for every sector of the green building community — from finance or policy to building

technology and LEED implementation to marketing — to learn about the changes in our rapidly evolving industry and anticipate what’s next. Greenbuild is an educational oasis, featuring more than 90 education sessions. Whether you are interested in taking a pre- or postshow LEED workshop, attending a sector-specific summit or learning about a niche topic, you will find it at Greenbuild. The majority of sessions at Greenbuild are approved for continuing education credits for LEED and other professional credentials, making it a one-stopshop for credential maintenance. LEED APs who are eligible to enroll in the LEED AP with specialty program should seize the opportunity to earn LEED-specific hours and attain a specialty credential. The suite of LEED AP with specialty credentials is what’s next in demonstrating proficiency in green building knowledge. If you are interested in what’s next — with LEED, in the globalization of green or in green building knowledge — Greenbuild is the can’t miss event of the year. Registration is open, and employees of USGBC member companies who register before Aug. 15, will save nearly $400 off full conference registrations. Start collecting your ideas, get your passport ready and register for Greenbuild NEXT. For information about education, exhibitors and to register, visit greenbuildexpo.org.

Cycling Improvement THE NEXT UPDATE TO LEED WILL CONTINUE TO IMPROVE THE CLARITY, USABILITY, FUNCTIONALITY AND INTERCONNECTEDNESS OF THE RATING SYSTEMS. The hallmark of the LEED green building program lies in its evolution and continuous improvement cycle. By constantly raising the green building bar, the rating system is flexible in its scope and stringency as acceptance in the market evolves and new technologies become widely available. Following the release of the LEED 2009 rating systems, the U.S. Green Building Council (USGBC) began working on an update to LEED to continue to support the transformation of how buildings and communities are designed, built and operated. Updating LEED presents opportunities for green building stakeholders to engage directly with the development of the LEED rating system. USGBC offers multiple public comment periods as part of the LEED development process. There is also a ballot vote among USGBC’s membership in addition to a Pilot Credit Library where project teams can submit feedback on various LEED credits that USGBC is offering for pilot testing. For LEED 2012, USGBC is focusing on the technical rigor of the rating system, incorporating building performance metrics and expanding the market sectors able to use LEED. The update builds on LEED 2009 and will continue to improve the clarity, usability, functionality and interconnectedness of the ratings systems through future version development. The following rating systems are included in the update: Building Design + Construction; Interior Design + Construction; Operations + Maintenance; Neighborhood Development; and LEED for Homes. LEED 2012 will supply three new credit categories and a revised point distribution. The new credit categories that will be introduced include:

ed+c

J U LY 1 1

Integrated Process, Location and Transportation, and Performance. Revising the point distribution will more closely align the rating system requirements to the environmental, social and economic priorities articulated by the USGBC community. In November 2010, USGBC launched the first public comment period for LEED 2012, which provided the first look at the next update to LEED. The proposed version reflected a year’s worth of development by USGBC’s committees. The public comment period closed on Jan. 19, 2011 and gen-

Comments and recommendations have been reviewed by staff and LEED committees during the last few months and revisions will be made to the rating system language based on comments, emerging themes and knowledge gained from participants in the Pilot Credit Library. Credit revisions will be made available during the second public comment period which is expected to begin in July 2011. At the end of the public comment process, a final draft will go before USGBC’s membership for a vote. The extent to which LEED can continue to evolve and create market transformation is dependent upon the feedback USGBC receives from its stakeholders. USGBC encourages all green building stakeholders to participate in the second public comment period so they can have an opportunity to influence the development of the content as it moves towards becoming a balloted rating system. Together, USGBC and its passionate and engaged members will continuously improve the rating system and move one step closer to achieving the shared vision of a sustainable built environment for everyone within a generation.

The Road to 100 THERE ARE A NUMBER OF LESSONS TO BE LEARNED ON THE WAY TO ACHIEVING 100 LEED CERTIFICATIONS, SOME THAT APPLY TO ANY SUSTAINABLE PROJECT. Every project is different and has its own set of challenges and possibilities. At Perkins+Will, we strive to leverage the unique opportunities that building programs, clients and sites provide. But, after 75 years of design and 100 LEED-certified buildings, we have found some principles apply to any sustainable project. Here is our short list:

Get Your Own House in Order

Stay Late (and Measure Everything)

It’s tough to sell a client on the value of sustainability when you haven’t bought into it yourself. The first step to credibility is to walk the talk. At Perkins+Will, aligning our operations with our values was essential. The development of our Green Operations Plan forced us to look critically at our own energy and water use, waste generation and CO2 emissions and to set hard targets for reductions. It led to a mandate that all new or major renovations of our offices would achieve LEED Gold or Platinum certification. This allows us to learn by doing. Our offices have become labs for testing design strategies and demonstrating sustainable performance.

Start Early One criticism of LEED is that you can “buy” a sustainable rating. Add a bike rack here or photovoltaic panels there and before you know it, your building is LEED certified. This has been partially remedied with the prerequisite energy requirement of LEED 2009. But, if you start with an institutional-quality building there is truth to this, especially in achieving LEED Certified or low Silver ratings. However, you can’t get to Platinum (or high Gold) with this

ed+c

J U LY 1 1

approach. It is prohibitively expensive. Achieving a Platinum rating requires a fundamental change in thinking. It requires all of the building’s systems be designed from the beginning with the common goal of achieving significant energy use reductions and high levels of sustainability. The window to effect change at a reasonable cost during the design process closes quickly; you must start early.

Another criticism of LEED buildings is they don’t perform any better than non-LEED buildings. In terms of energy performance this is true without proper follow through. Buildings are designed based on predictive models. Those models are based on a multitude of assumptions about how a client will occupy the space, climate and how systems will perform. Even in the best case, assumptions will not be 100 percent correct. Robust enhanced commissioning and extensive measurement and verification are critical for buildings to perform at levels matching predictive energy models. This means continual measurement, analysis and adjustment of building systems for at least 18 months after occupancy.

Get All Hands on Deck You can start on the path to sustainability with a few energetic early adopters, but to effect real change you need everyone involved. This means making sure your teams are pulling in the same direction and there aren’t two or three “sustainability experts” doing the heavy lifting while everyone else goes on with business as usual. At Perkins+Will, we require LEED Accreditation of all design professionals. This gives all our designers baseline knowledge of sustainability and an ability to engage in a sustainable dialogue. It lets everyone know, internally and externally, that we are serious about sustainable, high-performance design. And, it attracts like-minded clients and designers.

Frame Your Argument Every client has different values, goals and motivations. Sustainability framed in terms of benefit to the environment may not resonate with everyone. Knowing your audience allows you to discuss the value of

sustainability and LEED in terms that resonate with the audienceâ&#x20AC;&#x2122;s core values. One client may kick you out of the room for bringing up climate change, but would quickly sign on to high-performance building that saves energy costs. Another client may not be interested in sustainability, but is concerned about health and retention of staff. Instead of fighting a clientâ&#x20AC;&#x2122;s point of view, work with it. You will get more traction and, ultimately, a better project for it.

HIS PROFESSIONAL HONORS AND CREDITS INCLUDE THE 2010 AIA MINNESOTA YOUNG ARCHITECTS AWARD AND VARIOUS PROJECT AWARDS.

Take a Systems Approach One objection to sustainability is it is too expensive. This is common because we live with a reductionist world view. We break everything into parts and analyze them individually. We assume they are additive. The problem is that all parts interact and are dynamic. So, you have to look at them holistically. Indeed, adding a sustainable feature like daylight dimming will cost more upfront than not having it. Even with an argument of reasonable payback over time through saved energy, an owner is often hard pressed to come up with additional first-cost funding. But when viewed as part of a system, the reduced electric lighting levels may produce less internal heat and allow a smaller mechanical system. The dollar savings on mechanicals may offset increased first costs for daylight dimming. Only when the systems are designed holistically is this possible.

Optimize, Donâ&#x20AC;&#x2122;t Maximize In western culture, especially in the United States, we often believe that more is better. If two is good, then ten is great. One key to achieving sustainability is knowing which strategies to apply, when to apply them, and in what amount. For instance, it would be easy to assume adding insulation to a building envelope is always a worthwhile strategy. While this is often the case in an externally load-dominated building like your house, added insulation to an internally loaddominated building like an office rarely pays for itself. The money spent on added insulation would likely be better spent on a more efficient mechanical system. Even in your house there is a point of diminishing return where the amount of energy saved per inch of insulation added no longer provides worthwhile value. Knowing where to spend your budget is critical in achieving high sustainable performance. The road to 100 LEED Certifications has been invigorating. Each project is a step forward in our sustainable journey. They teach us something new. And by leveraging the cumulative lessons learned, we continually push forward toward our collective sustainable future.

School STRATEGIES NET-ZERO ENERGY BUILDINGS EXPERT ROUNDTABLE V

he fifth Net-Zero Energy (NZE) Roundtable focused its discussion on schools. The teams on these recently-built, or still-in-design or in-construction, schools wanted to share their experiences in order to help other professionals improve the energy performance on their future projects. The roundtable was broken down into two groups: the first group of schools is functioning (or will in the near future) as NZE schools now; the second group is designed to be NZE, but is still waiting to install the final, cost-prohibited items (such as solar collectors) to complete the process. The full transcript of the roundtable, as well as ED+C’s webinar featuring Richardsville Elementary School, can be found on EDCmag.com.

Now in its second phase, Marin Country Day School site overlooks the San Francisco Bay. The design emphasized connecting the children with the site’s natural ecology as a part of imparting ecological literacy with the students as called for by the school’s new Strategic Plan. The building itself set out to achieve LEED Platinum in addition to net-zero energy. Strategies that worked with the school’s environment were employed. For example, a radiant slab with concrete fill over an exposed metal EPIC deck cools the facility. The design reduces the need for cooling enough that a cooling tower was used in place of an energy chiller. Climate conditions also allowed for a baseboard heating system.

Scheduled to open in August 2011, the new middle school will serve as Irving Intermediate School District’s eighth middle school. Incorporated into the main circulation spine of the school are four educational displays called “nodes.” Each node is dedicated to a sustainable principle: solar, geothermal, wind and water conservation. Each node has three components: a graphic display where printed material can be displayed and easily changed, a digital display of four large touchscreen monitors that can display real-time data for all of the systems (as well as video or other data needed to support the curriculum), and a threedimensional interactive display. Building efficiencies and energy reduction are accomplished by a geothermal HVAC system, increased wall and roof insulation as well as insulation under the floor slab, due to the crawl space required by soil conditions. The electric plug load in the building has been reduced by half because of a district commitment to student laptops and wireless networking that allows for the elimination of all computer labs and banks of library computers.

To supplement the daylight strategy on the second floor, two tubular daylighting devices were located in the back of the classroom to help distribute the daylight evenly. The building’s climate required year-round heating and cooling. Therefore, it was decided early on that a high-performance envelope was necessary. Insulated concrete forms for both the perimeter and interior walls of the building were chosen. For the roof, six inches of polyisocyanurate insulation was selected in order to increase the roof R-value to 42.

The long axis of the school is oriented east-west to best take advantage of passive strategies related to solar access and direction of prevailing winds. Based on a study that collected information from hundreds of school across Canada, the design team was challenged to be as efficient as possible and is aggressively targeting an annual kilowatt usage between 60 and 70 kilowatt hours per square meter. www.EDCmag.com g

In a harsh climate where there are 8,500 heating degree days and only 51 cooling degree days, a well-insulated building that makes use of passive solar strategies was necessary. The project used funding from Colorado’s BEST Program, which stands for Building Excellent Schools Today. The BEST program is funded by the State of Colorado’s land trust, which manages three million acres of land and four million acres of mineral rights, established by the Colorado State Legislature and the Colorado Department of Education in 2008. This program provides an annual amount of funding in the form of competitive grants to school districts and charter schools throughout the state.

Named after a former graduate and founder of Earth Day, Denis Hayes, the focus of this school’s alternative learning environment focuses on environmental stewardship. Its smaller footprint naturally lent itself to a green design. Student and faculty interest in sustainability features permitted the design team to forego active cooling systems and certain interior finishes, the funds for which were then diverted to upgrades to the sustainable features.

Peter Rumsey, principal/practicing engineer, Integral Group. prumsey@integralgroup.com

NZE consultants focus on designing a low energy building first so that photovoltaic systems are smaller and more affordable. Photovoltaic systems are then typically used to provide renewable energy to the building. Surprisingly, some school districts have been able to outright pay for these systems stating that it’s easier to get construction dollars rather than operation dollars. Other districts, however, prefer to go with a power purchase agreement (PPA) in which a lease-type of arrangement is made where third-party providers of PV systems can claim the tax credits and the district doesn’t have to pay for the PV system. In addition to the above participants, other industry professionals contributed their expertise to the roundtable, including Rick Cantwell, PE, President/CEO, Odell International LLC, Huntersville, N.C.

The ASHRAE Advanced Energy Design Guides (AEDGs) are a series of publications designed to provide recommendations for achieving energy savings over the minimum code requirements of ANSI/ASHRAE/IESNA Standard 90.1. The initial series of guides have an energy savings target of 30 percent, which is the first step in the process toward achieving a net-zero energy building, defined as a building that, on an annual basis, draws from outside resources equal or less energy than it provides using on-site renewable energy sources. Each 30% Guide addresses a specific building type. Additional guides for existing buildings and at 50 percent energy savings toward a net-zero energy building are also planned and currently in progress.

The organization’s first criteria was created after the original LEED criteria was completed, allowing many of the people who created that original criteria for office buildings was able to create criteria for schools. It started in California, with the California Energy Commission and the major California utilities. The criteria are now in 11 different states, four of which are managed through the national office in California. Those criteria are California Colorado, Texas and Massachusetts.

To start, define as part of the sustainability goal-setting session, your team’s definition of net-zero energy and/or other energy conservation goals. Grid neutral only considers electricity use, while net-zero energy (site or source) includes electricity and natural gas, and “carbon neutral,” offsets any carbon produced from the natural gas and electricity use of the buildings. Make sure to also define the boundaries of the goal and how the goal will be measured to confirm whether or not the goal has been met. As a recommended net-zero energy design tip, it would be useful to set up a matrix that identifies best practices for achieving netzero energy and categorize them by climate and building program needs.

J U LY 1 1

A client representing a large multibuilding campus recently asked whether the USGBC’s 2010 LEED Application Guide for Multiple Buildings and On-Campus Building Projects (2010 AGMBC) might provide a specific benefit or applicability to use across this client’s campus building stock. The 2010 AGMBC provides a streamlining of effort (and potential cost savings) for owners with multibuilding campuses. Please note that the 2010 AGMBC is applied on LEED v2009 projects only. Projects registered under previous versions, such as LEED-NC v2.1, 2.2 or LEED-CS v2.0, need to use the 2005 AGMBC as applicable. The 2010 AGMBC can be applied to the New Construction, Core and Shell, Retail, Healthcare and Commercial Interiors as well as the LEED-EBOM rating systems. This “campus” application guide applies to a single site under a single owner or management entity. This can be a college campus, military base, corporate campus, etc. Unlike the LEED Volume Program, which is used to certify a large number of projects based on a uniform building type, the 2010 AGMBC is used to certify multiple buildings not necessarily of the same type but located on a single site. However, on some campuses, owners could apply both programs should their building types be prototypical. Many commercial office campuses meet these criteria. Many of the equipment and material selection-related LEED credits (i.e., water saving fixtures, low-VOC paint, etc.) can be applied fairly universally across an owner’s building portfolio. Plus, when applying the sustainability policies (waste management, water use, purchas-

ing, etc.) required by LEED-EBOM rating system campus-wide, the resulting time and effort savings can be significant. Applying the 2010 AGMBC requires an initial registration submission to the USGBC of a master site. This master site registration should be submitted prior to submitting individual campus projects for their eventual LEED certification review, but they can be done concurrently. Owners need to know that separate LEED registration (and payment of associated fees) is still required for any project being submitted for LEED certification on their campus. Registration fees for the master site are the same as for individual buildings — $1,200 for non-USGBC members and $900 for members. Certification fees for the master site are $2,000 for non-USGBC members and $1,500 for members with a 20 percent discount on certification fees for each individual building applying for certification under the 2010 AGMBC. Thus, perhaps with just two or three buildings, the investment in this campus approach begins to save on overall costs. One of the primary items to be addressed under the 2010 AGMBC is to define the LEED campus boundary in the master site submittal. This has great bearing on the application of credits (specifically any credits addressing site or FTE requirements), as any and all buildings within the campus boundary must be included in the overall calculations — whether those buildings are seeking LEED certification or not. Individual buildings must still be submitted with a defined LEED project boundary. The LEED campus boundary must be a contiguous site, unless specific criteria are met as defined in the

supplemental guidance to the minimum program requirements. Credits can be added to the master site registration via the appeals process in LEED Online at any time. Just a few examples of where campuses can benefit from the master site credit approach include: Using a centralized recycling collection area versus individual building recycling centers, thus alleviating space planning and other associated issues across campus building stock; establishing a non-smoking policy for the campus; purchasing green power and assigning the power purchased on a by-project basis; water-efficient landscaping; and green cleaning and integrated pest management programs. Also to be noted, as updates to the LEED rating systems occur, (the next one is planned for 2012), owners will need to re-review all campus credits (at their own expense) to ensure the credits in their master site will be applicable to the new rating system. Certainly there are substantial benefits an owner could garner by pursuing the campus approach if the intent is to seek LEED certification for multiple campus buildings. The unique aspects of each campus need to be assessed to verify the totality of the benefit, but with the upside potential, this is an option all campuses should consider.

THE GREEN

PRACTITIONER By Tommy Linstroth, LEED AP

Incrementalism and LEED THE LEED RATING SYSTEMS HAVE CONSISTENTLY ADAPTED AND BEEN REVISED AS THE GREEN BUILT ENVIRONMENT GROWS.

THERE IS A CONTINUED PUSH FOR LEED REQUIREMENTS TO BECOME MORE STRINGENT AND RIGOROUS.

Ten years ago, there was this fresh new kid on the block, one no one had seen before. Wildly different than the common way of thinking about designing and constructing buildings, this new concept was seen by supporters and critics as visionary, radical, market-changing, unnecessary, useless and industry defining. I’m guessing you won’t have to think too hard to realize I’m talking about the LEED rating system. A mere decade or so ago, LEED was introduced to a range of emotions and reactions on both sides. Indeed, while more commonly accepted today, the system still raises strong feelings, both for and against. What’s odd is that this rating system — or what could even be called a reformed thought process — that was once heralded as a visionary new system for defining green buildings has come to be derided as not stringent enough, not pushing the envelope enough and certainly no longer visionary. This comes from some of the rating system’s most ardent early supporters. That leads me to weigh the pros and cons of both arguments of the future evolution of LEED. I’ve lived neck deep in LEED and green buildings for the better part of the past decade. I’ve dealt with the industry learning curve, the certification frustrations and the perceived cost issues that seem to be brought up by everyone as soon as those four little letters are declared. But I’ve also basked in the glow of project teams hanging their plaques, never looking more satisfied; of communities rallying behind projects because the

developer has made a true commitment toward making buildings and neighborhoods better; of talking to facility people who are amazed by how low the actual utility bills really are. It’s a tough job being a visionary. Actually, being a visionary is easy. Being a successful visionary is something else. Let me explain. There are lots of visionaries. Lots! You’re probably one or are sitting next to one. But the biggest problem with many visionaries, at least the ones I see, is that they have no ability to implement. It’s easy to come up with a visionary idea (this building should run off of smiles and self-esteem!), but taking that vision and getting it done is something else altogether. Visionaries better have some dang good technical and detail-oriented people working with them, a never-ending passion and years of dedication; otherwise, that vision goes nowhere. So — what does that have to do with anything? Well, LEED was visionary 10 years ago. I think the greatest sign of success for something truly visionary is that it doesn’t seem all that out there anymore. In a decade, what was once a wild idea for green building certification has become the norm — elevating building design and construction to a level not usually seen. No, a building doesn’t have to be LEED certified to be green, but as I’ve often wrote about, a lot of those folks I’ve met who’ve told me they “already design/build buildings that would be LEED certified” usually produce projects that don’t measure up. There is a continued push for

LEED to become more stringent and rigorous in determining requirements for a project to gain certification. And the rating system has adapted, consistently, over the past 10 years. That’s the beauty of it. The energy component especially is much more rigorous than it was when it was based off of ASHRAE 90.1-1999. Can you make it tougher for the amount of bike racks and showers? Not really, but you see the improvements where it is really practical and really makes long-term differences, like energy, water and indoor air quality. There are some new rating systems out there looking to push well beyond what LEED is currently prescribing — things like the Living Building Challenge. I certainly hope they succeed and in 10 years I’m writing about the success and market-transformation of those systems. But until then, I’ll leave this question to both the visionaries of great new things to come and the folks who don’t like the incremental improvements to the LEED rating system. Is it better to have one building completely off the grid (perhaps powered by smiles and self-esteem), or 5,000 buildings using 20-30 percent less energy? Visions are great and necessary — but so are things that are so successful they become common. TOMMY LINSTROTH, LEED AP, IS THE PRINCIPAL OF TRIDENT SUSTAINABILITY GROUP (WWW.

An efficient plan, solar panels and a wellinsulated envelope mean that little supplementary heat is needed. Strawbale walls wrap the north and west, while the woodframed south wall features extensive glazing,

opening up to the sun to bring daylight far into the living spaces. Deep overhangs and trellises shade the spaces in the summer time while still filling the rooms with daylight. With no mechanical cooling, natural ventilation occurs by simply opening windows, particularly the high windows in the two-story dining space which can be left open for night flushing if necessary.

The dramatic height of the dining room is accentuated with the natural branching of a madrone tree column, found by the owners on a friend’s nearby property. The open dining room is balanced by an intimate living space with a sitting bay rotated toward the park. Recycled and salvaged doors, interior windows, flooring and driftwood pickets, as well as a driftwood column at the entry, reduces the impact of the building and provides character and sense of place.

THE PEARL’S UNIQUE DESIGN OPTIMIZES PASSIVE SOLAR

pearl of wisdom COLLECTION YEAR ROUND WHILE OFFERING OCCUPANTS

SAFETY AND COMFORT.

By Derrick Teal

olaleya Design first introduced its Domespace house to the U.S. market in 2007. The design, utilizing a motor to rotate the entire structure relative to the sun to increase or decrease solar collection, was intended to dramatically reduce energy consumption versus traditional housing. Solaleya Design’s latest model intends to equally reduce energy consumption while leaving the motor behind. Dubbed “The Pearl,” Solaleya’s latest offering is aiming for LEED Platinum certification. One of two model types offered by Solaleya, this project is highlighted for its energy efficiencies (thanks in part to an effective passive solar design) and selective material use. The economically viable structure is completely customizable. The structure can be sized between 500 to 5,000 square feet with a bevy of layout options and finishes available. All of the available options are intended to be equally balanced and easy to maintain without taking away from the structure’s main purpose and identity. The initial model has three bedrooms/two baths within its 2,800 square feet. It is equipped with a white (sun reflecting) steel roof finish and a rainwater recuperation system

ideally located at the base of the northern pedestal. The Pearl is the brainchild of French designer David Fanchon, who combines his understanding of human form and its sensibilities with architecture to design

optimally balanced habitats. The inspiration for the design is apparent at first glance. “I have to say that my main focus was to give a heart to the structure,” Fanchon says. “Putting the main living area at the very

center of the 180 degree bay windows creates a sense of conviviality where all inhabitants share a privileged space. This would have been the location of the actual “pearl” in the original seashell — a place where it is able to gather

all the energy and protection to grow, hence the house’s chosen name. I hope this house brings people together with a greater sense of awareness of the world around them.” Fanchon’s philosophy behind The Pearl’s design is “Functional Beauty”: create ideal conditions for people to live and blossom in harmony with our environment. He says that he strives to propose innovative sustainable housing solutions, blending aesthetics, functionality and energy efficiency with an emphasis on optimized architectural form and the rigorous choice of ecological materials. In this case, as in others, he gives credit to Mother Nature for the design. “As far back as I can remember, I have always been fascinated by the way nature best adapts to its surrounding,” says Fanchon. “It is a great source of inspiration and discovery. This specific structure is inspired from a seashell which offers great structural strength and aerodynamics. I found that by adapting its shape and attributes www.EDCmag.com

to our habitats, it would greatly serve our purposes of strength and protection with a twist of sun-catching optimization.”

Conservative Alternative The unique structure was designed with both the sun’s daily and year-round course in mind. Its shape is optimized to take advantage of the Sun’s benefits when needed and to protect from its harsher heat when necessary. The front of the structure offers large bay windows to take advantage of the sun’s heat in the winter while being completely protected by its adapted roof during summer’s warmer days, therefore keeping the house’s interior naturally cooler. This translates into a reduced need to

artificially heat and cool the interior. Its unique shape and inclinable solar panels provide maximized solar energy gains and additional shade when necessary. â&#x20AC;&#x153;My first goal was to design a passive structure in order to reduce its need for energy. Its intrinsic seashell shape offers unparalleled passive solar efficiency. Adding optimized solar panels along with geothermal heating/cooling also allows for greater energy independence. As I wanted to design a house that would be balanced and easily adapted to most climates and season changes, I then added climate control features such as top window vents and multilayered insulation.â&#x20AC;? Insulation in the walls consists of cork www.EDCmag.com

The Pearl is anti-seismic and aerodynamic. The roofâ&#x20AC;&#x2122;s shape along with the use of thick wooden arches procures the structure with great resistance against earthquakes and high winds, providing inhabitants with the incomparable comfort and safety of a cocoon. But certain elements of the structure were initially a challenge to the design. As many ecologists and environmentalists know, nature has had far longer to perfect its designs than humans have. Fanchon explains, â&#x20AC;&#x153;My early version of this design attempted to stretch the shellâ&#x20AC;&#x2122;s shape. But I soon found that in order to overcome most structural challenges I needed to simply emulate natureâ&#x20AC;&#x2122;s patient evolutionary work to the dot. I then created a northern concrete pedestal to strengthen the arches converging base and extended arches all the way to ground level on the open side in order to create greater structural integrity.â&#x20AC;? The arches used exemplify the serious thought put toward material selection. According to Fanchon, FSC Alaskan cedar arches were chosen to provide unparalleled strength against earthquakes. Since the design was intended for a variety of climates, earthquake protection wasnâ&#x20AC;&#x2122;t the only natural disaster considered. â&#x20AC;&#x153;Even though I used impact-resistant windows, I also imagined a hurricane-proofing option that would allow to easily and quickly close the entire front terrace of the structure to protect its large bay windows,â&#x20AC;? says Fanchon. â&#x20AC;&#x153;The system uses reinforced vinyl covers stretched between arches. Once installed, they are held strong with a set of thick cables that belt the entire front of the structure at different levels anchoring back in the concrete pedestal.â&#x20AC;? By incorporating the lessons learned by nature throughout the history of the Earth, The Pearl is proof that some manmade gems are equally precious.
