The next big thing in energy conservation? Small commercial buildings

Posted on June 11, 2013

The following post is by the Preservation Green Lab:

A new report released by the Preservation Green Lab in Seattle says an array of energy savings in small commercial buildings across the United States could profitably yield more than one quadrillion Btu annually, which translates into more than $30 billion in annual cost savings and improved financial performance for small businesses.

Conservation efforts commonly focus on larger structures, but 95 percent of all commercial buildings are less than 50,000 square feet. This is a massive and largely untapped opportunity for new energy savings.

“The energy savings detailed in our report represent the equivalent of 580,000 permanent new American jobs,” said Mark Huppert, Director of the Preservation Green Lab, and a lead author of the report. “Harvesting energy efficiency from small buildings is like striking oil, except it’s domestic, clean and keeps dollars in our local economies. The savings will produce real jobs that can’t be offshored or outsourced.”

Ninety-five percent of all commercial buildings are less than 50,000 square feet — a largely untapped opportunity for energy savings.

The report, “Realizing the Energy Efficiency Potential of Small Buildings,” was produced by the Green Lab in partnership with the New Buildings Institute, a nonprofit that works collaboratively with commercial building interests to remove barriers to energy efficiency. The analysis was funded jointly by The National Renewable Energy Laboratory and the U.S. Department of Energy.

Here are the key findings:

  • Small buildings are responsible for 47 percent of the energy consumed by commercial buildings.
  • Small businesses or firms with fewer than 500 employees own 84 percent (3.7 million of 4.4 million total) of small buildings.
  • Potential energy savings in small buildings range from 27 to 59 percent, depending on the building type. This represents 1.07 quadrillion Btu annually or 17 percent of commercial energy use.
  • Small, neighborhood businesses such as restaurants, grocers and retailers can improve profitability by more than 10 percent through smart investments in energy savings.

The report recommends that utility regulators create incentives for energy efficiency to unlock the potential savings in these smaller buildings. Pilot projects that pay customers for measured energy savings could demonstrate how the private sector can drive down energy costs while utilities continue to earn a profit. These innovative programs also offer utilities the opportunity to burnish their images.

Some utilities are already embracing this approach. “I believe the cleanest power plant that I will build in the future is the one that I don’t build,” said Duke Energy CEO James E. Rogers during a 2012 address to the Urban Land Institute.

Programs that engage small businesses owners represent a big opportunity for the financial sector, as well as for the businesses themselves. “Since 2005, Wells Fargo has financed more than $21 billion for “green” businesses, “green” buildings, and “clean” energy customers, including $900 million in loans and investments benefitting low-income communities or housing projects,” said Andrew Kho, senior vice president with Wells Fargo Commercial Banking. “These investments can help our customers reduce their monthly operating expenses and support a transition to a “greener” global economy.”

The Preservation Green Lab is a sustainability think tank focused on the reuse and retrofit of older and historic buildings. A project of the National Trust for Historic Preservation, the Green Lab was launched in 2009 and is based in Seattle.

New module from Marysville solar manufacturer

Posted on November 30, 2012

The following post is by Silicon Energy:

Silicon Energy, a manufacturer of solar photovoltaic modules in Marysville, said it is releasing the Next Generation Cascade Series PV module.

The first generation came out in 2007.

The new module uses less embedded material, which improves performance and output.

Silicon Energy's new photovoltaic panels.

Here are some features of the new module:

· Anti-reflective coating on the front glass

· Advanced encapsulant

· Lighter weight mounting hardware

· About 30% fewer roof penetrations to reduce costs and speed up installation

· 12 AWG wire for reduced voltage drop

· Amphenol connectors with a higher current rating and increased reliability

· American Fittings Raintight conduit connectors that improve mechanical and electrical bonding

Gary Shaver, president of Silicon Energy said, “Our relationships with suppliers and research laboratories allows our engineering team to integrate innovative concepts and advanced material sciences into our products. We’re excited to see how architects and building designers integrate our new, even more attractive Cascade Series PV modules into the building envelope and overhead structures to achieve contemporary and functional designs.”

The module has a double-glass, open-frame design to shed water, dirt and snow. Airflow behind the module keeps the system cooler, which boosts performance.  Custom mounting hardware colors are available.

Silicon Energy is shipping the Next Generation module to Washington customers and will introduce it in other markets early next year.

Silicon Energy was founded in 2007, and is located in Washington and Minnesota.

Crunch the numbers and preservation wins

Posted on November 16, 2012

The following post is by Kathleen O'Brien:

New is not always better.

I have to confess that I've been a little put off by local historic preservationists self-righteously declaring that "preservation" equals sustainability and leaving it at that. Yes, yes, I understand that recycling buildings intuitively makes sense, but since sustainability sometimes asks us to think counter-intuitively, I needed more. At a recent Sustainable Cities Roundtable conducted by King County's Green Tools Program, I got what I needed.

Photo courtesy of McKinstry

The previous owner used stacks of wooden pallets to keep the ceiling from falling in on this 104-year-old railroad building in Spokane, but McKinstry bought it and spent $20 million to create high-tech office space for its 150 Inland Northwest employees.

Robert Young, PE, LEED AP, is professor of architecture and director of the Historic Preservation Program at the University of Utah, and author of the new Island Press release, "Stewardship of the Built Environment." He was guest speaker at the Roundtable. Young provided some very satisfying arguments for promoting preservation and building reuse as a sustainability strategy. In making his arguments, he gives equal weight to what he terms SEE (or what some of us have called the "three E's"): social, economic, and environmental factors, and defines stewardship of the built environment as "balancing the needs of contemporary society and its impact on the built environment with the ultimate effects on the natural environment."

The Historic Preservationists have been at their best when justifying conservation due to social factors, and Young does speak to this. What I appreciated is that he also addresses environmental and economic factors in an analytical but highly accessible manner. One of the areas he touched on in his talk was the idea of calculating energy recovery as part of understanding the energy performance of preservation vs. new construction. As Young notes in his book, "the argument for measuring embodied energy to justify the retention of a building is (still) met with skepticism." He claims this is largely because embodied energy is considered a "sunk cost" and therefore not part of decisions about future expenses. I think he would also say it's because of our societal preference for the glitter of "new" vs. the practicality of "existing," which may not be part of the accounting equation, but certainly humming in the background.

In his talk, Young used his own home to compare the energy recovery periods required to simply perform an energy upgrade to his home, to abandon the home and build a new one in the suburbs, or to demolish and rebuild in place. When he accounted for the embodied energy in the new buildings (whether in place or in the suburbs), the energy to demolish the existing building, and operating energy required for the remodeled or new building, it became clear that the remodel was the best choice when considering true energy performance. In scenarios provided in his book, energy recovery calculations result in recovery periods that exceed "the expected useful lives of many buildings being constructed today." And this is without calculating in the transportation energy expenses that are likely to accrue when the new building is built in a greenfield out in the suburbs.

In the economic realm, Young compared the job creation resulting from highway, new, and rehab construction. In jobs per million dollars spent, rehab wins again. Although a small part of the construction activity (Young estimated 5%), rehab creates roughly 5 more jobs per million dollars spent than highway construction, and 2 more jobs per million dollars spent on new construction. If I am interpreting Young's figures correctly, just by turning our economic recovery lens on rehab and away from highways and new construction we could potentially create between 6-12% more jobs per million dollars spent on construction. (And we might actually reduce the environmental, social, and economic negative impacts of sprawl -- even if it's "green")!

Young's talk introduced some great food for thought, but I'm so glad to be reading his book. In his concluding chapter, "Putting it All Together," he provides a list of "challenges" for stewards of the built environment, ranging from advocating outcome-based codes (since prescriptive codes are based primarily on new construction practices) to presenting project lessons learned (both positive and negative) to "decision makers and policy shapers who mediate building preservation and reuse policies." Lots to work on.

When greening your office space, don’t overlook the plugs

Posted on November 6, 2012

The following post is by the New Buildings Institute:

To help commercial building owners and occupants get control of the growing amount of energy used by office equipment and other electronic devices, New Buildings Institute released the Plug Load Best Practices Guide. It is based on research done by Ecova and NBI for the California Energy Commission's Public Interest Energy Research Program, and gives advice on how to save money by reducing energy use in offices.

Lyn Baxter | Dreamstime.com

Plug loads account for 15-20 percent of electricity use on average.

On average, plug loads account for 15-20 percent of electricity use. For offices that have already improved the efficiency of lighting and HVAC systems, that number can be as much as 50 percent. The impact of plug loads can be reduced by up to 40 percent through a combination of no- and low-cost steps such as:

•  aggressive power management settings

•  inexpensive hardware controllers like timers and advanced plug strips

•  occupant-based strategies

When the time comes to replace equipment, buying new energy-efficient models can also reduce energy bills. The guide also gives advice on how to manage energy used by computer server rooms.

According to NBI Senior Project Manager Amy Cortese, "Owners, tenants, purchasing managers, IT directors and building occupants all have a role in managing plug load energy use. Our goal with the Plug Load Best Practices Guide is to help them establish a workable plan for cutting that energy use."

The largest plug load energy users are computers, monitors, imaging equipment, server rooms and computer peripherals.  The guide outlines steps for selecting the highest efficiency equipment for a given job when it's time for replacement. "Simple equipment upgrades and making sure that control settings in most office equipment are enabled can make a huge difference," said Cortese.

"Through this research, we found that occupants can and should play a significant role in managing energy use," she said. "This guide will help office managers engage tenants and occupants in learning about these simple measures and ultimately reducing their own energy and utility costs."

The Plug Load Best Practices Guide is part of Advanced Buildings, a set of tools and resources designed to help improve the energy performance of commercial buildings. Funding support for development of the guide was provided by the California Energy Commission's PIER Program.

New Buildings Institute works with commercial building professionals and the energy industry to promote better energy performance in buildings.

Ellensburg’s energy strategy shows one size does not fit all

Posted on May 9, 2012

The following post is by Kathleen O'Brien:

I had the pleasure this past month of presenting the final product of a two-year process with the City of Ellensburg and its residents for approval. The Energy Efficiency & Conservation Strategy (EE&CS) is one of dozens across the country that were funded through DOE Energy Block Grants. In this case, the grant was administered by the State's Department of Commerce and locally by the city's Planning Department.

O'Brien

There are basic elements that are required for every EE&CS, such as developing a vision statement and goals through a public process, and reviewing existing conditions to measure progress. But in looking at the various EE&CS produced around the U.S., it's clear that each community leaves its very own stamp on the process.
Anyone who's traveled to Ellensburg for its annual rodeo knows the city has an independent streak, so it is no surprise its EE&CS should be a "little different." The EE&CS draws on the fact that Ellensburg is one of the few cities of its size that has its own electric utility, and was the first city to create a community-funded renewable energy park, so there was a lot already happening.
In addition, the EE&CS was aligned with a concurrent update of the Land Development Code to make hay of opportunities to use the code to encourage energy efficiency in development and transportation.

Ellensburg Rodeo

 

Another defining aspect is that the city clearly wanted a planning tool, not a plan. So although there are guidelines and templates for developing plans that address the strategy's focus areas, and background information from which to draw on, the action plans themselves are left for the city and community to complete over the next planning cycle(s).
Case studies in the EE&CS document are meant to inspire local action, not be imported. The upside of this approach is flexibility, something the city really wanted. The downside (and frankly this is always the danger) is that the EE&CS could end up sitting on a shelf.
When asked by a Council member what would make the difference between successfully implementing the EE&CS tool and its being shelved, I responded: "The difference is you -- your leadership will make the difference."
After a brief pause, the council member said gamely: "I think you're right!" and his fellow members of the council grinned. The EE&CS was unanimously adopted.
Let's see what happens next!

Community Power Works expands services to all of Seattle

Posted on April 13, 2012

The following post is by Christine Grant, an associate at Cascadia Consulting Group.

“We just got a $1,200 bill from the oil company.  We just can’t afford it anymore,” lamented a Seattle resident who recently called the Community Power Works for Home customer service line.

The Community Power Works customer service team is used to hearing stories like this. Hundreds of Seattle residents have turned to CPW over the last year because of high energy bills, drafty windows, an old furnace that just can’t warm the house, or moldy insulation that is worsening allergy symptoms.

CPW contractors Bob Thorson and Charlie Rogers

“The best part of the job is being able to tell residents that have cold, leaky homes and high energy bills — Community Power Works can help!” says Maryellen Hearn, a customer service representative.

Participating in Community Power Works starts with a home energy assessment called an Energy Performance Score, or an EPS.  The EPS measures your home’s energy efficiency and determines the recommended upgrades that will reduce energy use and make your home healthier and more comfortable. This assessment is valued at $400, but costs Community Power Works participants just $95 thanks to a special rebate from Seattle City Light. Over 800 Seattle residents have received an EPS through Community Power works since the program started last April. The results from the EPS are educational — and often motivational too.

“When we learned that 86 percent of the warm air in our house was escaping each hour and being replaced with cold air from outside, we were shocked. That provided us with the motivation to act,” said Washington Park home owner Allyson Adley.

Common energy efficiency upgrades include duct sealing, floor and wall insulation, window replacements, and heat pump water heaters.  A very popular upgrade has been the installation of a ductless heat pump — especially for customers who had oil heat and wanted to switch to electric heat.  Community Power Works home energy auditor, Charlie Rogers, explains that, “if you heat with oil, you are probably spending between $1,000 and $2,000 annually on oil to heat your home, and possibly more based on fluctuating crude prices.” Yearly heating costs for an average Seattle home with an electric ductless heat pump are much lower — usually between $189 and $394. Community Power Works is also currently offering a $1,200 incentive for all customers who install a ductless heat pump, in addition to a range of other incentives that could save you thousands of dollars.

The average Community Power Works customer increases the energy efficiency of their home by 30 percent — this not only increases the comfort of a home, but also the asking price once it comes time to put the home on the market. Starting last fall, the green features and energy efficiency of homes are now being considered formally as part of the home appraisal process. Buyers are also quick to start adding up what utilities are going to cost them — especially if they are looking at an older home.

Community Power Works for Home recently expanded to serve all of Seattle — you can sign up here.

Community Power Works also plans to conduct energy upgrades at four local hospitals — Virginia Mason, Swedish, Harborview, and Group Health — by June 2013 while also upgrading hundreds of small businesses and more than a dozen municipal buildings.

Dan Bertolet looks at success, cost efficiency of Issaquah’s zHome

Posted on November 10, 2011

This is a guest post by Dan Bertolet, founder of Citytank and an urban planner with Via Architecture.

Over the past few decades designers and policymakers have been working to increase the energy efficiency of buildings, and solid progress has been made. Still, today in the United States buildings account for 49 percent of energy use and 46 percent of greenhouse gas emissions. Successfully tackling the dual challenges of rising energy costs and climate change is going to take massive reductions of building energy use.

A conceptual holy grail for energy-efficient building design is a building that generates as much energy as it consumes, a.k.a. a zero net energy building. And that's the goal of a recently completed 10-unit townhome development in Issaquah, WA, known as zHome, touted as the “first multifamily, production, zero-energy, carbon-neutral community in the United States.”

Image courtesy Dan Bertolet

Spearheaded by the City of Issaquah, the zHome project was awarded to David Vandervort Architects in Fall 2007, but subsequently the real estate bust forced the original builder to back out. Howland Homes took over in Summer 2008, and the project broke ground that September. Faced with financing challenges and delays, Howland then partnered with Ichijo, a large Japanese builder known for energy-efficient production homes, and the project finished in September 2011.

zHome was designed to achieve zero net energy use through efficiency measures that reduce consumption by about two-thirds, and photovoltaics (PV) that generate enough electricity to cover the remaining third---approximately 5,000 kWh per year. That requires a hefty amount of PV, and indeed, the south-facing panels that cover the roofs are a prominent feature. During the sunny summer months the PV produce more energy than the buildings need, and the excess is fed back to the grid. If the building operates as expected, that "banked" energy will offset the energy consumed during the dark winter months when PV output is low, the result being zero net energy use on an annual basis.

Energy-efficiency measures incorporated in zHome include ground source heat pumps that provide space heating and domestic hot water, heat recovery ventilation, a tightly sealed and highly insulated envelope (R38 wall, R63 roof, U-0.33 double pane windows), efficient appliances, LED lighting, switched outlets to reduce phantom loads, and a real-time energy monitoring system. (The project is also designed to reduce water consumption by 70 percent.)

So how much did all that extra stuff increase the cost? Asking prices for the units are relatively high for Issaquah: $385k for 799 s.f. 1-bedroom; $530k for 1350 s.f. 2 bedroom; and $625k for 1694 s.f. 3-bedroom. Apparently the free land and significant logistical support provided by the City weren't enough to negate the cost premium. Eventually the upfront investment in efficiency would be offset by savings in the energy (and water) bills, but given current energy prices payback periods are relatively long. Of course, if all the externalized costs of our energy were included it would be a different story, but unfortunately a carbon tax is not happening any time soon.

It remains to be seen if zHome will achieve zero net energy performance in the real world, and success will likely depend to some extent on the energy use habits of the occupants---one thing designers don't have much control over. In any case, whether or not a building can produce enough energy on site to hit net-zero isn't necessarily the be all and end all for sustainable design. Arguably, what's more important is the practice of "efficiency first"---that is, first figure out how to fully minimize the building's energy use, and then worry about how to supply the remaining energy demand.

Image courtesy Dan Bertolet

For example, the Bullitt Foundation's Living Building is targeting zero net energy and incorporates cutting-edge energy-efficient design. But analysis suggests that it could have been even more efficient if it had been built to the European Passive House standard, in which case it would have required less PV, potentially reducing both cost and physical design constraints.

Furthermore, when you look beyond the single building and consider larger systems of buildings and energy production, in some cases powering a building from an offsite energy source may make more sense than struggling to max out on-site generation. And for buildings taller than about six or seven stories, there simply won't be enough solar energy impinging on the site to meet demand, even for a hyper-efficient building.

In conclusion, while the concept of zero net energy buildings may have its limitations, projects like zHome and the Bullitt Foundation building remain hugely important for making progress on energy-efficient design. That's because they challenge designers to (1) work within a highly constrained energy budget, and (2) explore the limits of on-site energy production. And then there's also the potential for the big win as the designs move into the mainstream. Indeed, Ichijo has ambitions to ramp up the zHome concept to high-volume production. It won't be a moment too soon.

Will private developers pick up living buildings?

Posted on November 3, 2011

In Fremont, a different kind of living building is in the works: it's being built by a private developer.

The five-story, 120,000-square-foot building is being developed by Skanska and

Rendering_Brooks
is Skanska USA’s first development effort in the Seattle market. (Talk about a way to come to the market with green guns-a-blazing!)

Brooks Sports is the anchor tenant and will take 80,000 square feet and move 300 employees into the space in late 2013.  Skanska said it would lease the site from the owner, Fremont Dock Co. The site is at 3400 Stone Way N., next to the Burke Gilman Trail and near Lake Union.

This project is of course fascinating because it’s a living building, widely considered the toughest green building certification on the planet. But another thing that makes it stand out is who’s building it. All living buildings on this coast that I'm aware of are built by schools (University of British Columbia's CIRS project); nonprofits (the Bullitt Foundation's headquarters in Seattle); consortium's of city groups or donors (The Bertschi School Science Wing); or partnerships involving all of the above (the Oregon Sustainability Center in Portland). There's also a few home projects thrown in. These groups have various resources (tax credits, donors, endowments etc.) that a standard developer doesn't have access to.

Skanska's project in Fremont is the first I'm aware of to be built by a commercial developer on its own. Granted, it is being self-financed. But the fact that Skanska is building it means the company sees a future in living buildings. It's taking a chance! In the scale of things, it will be incredible to see how this project works out because it will inevitably be used as a living building test case for other developers.

Living buildings are fascinating creatures but they're not cheap. Generally, I'm hearing that developing a living building costs a third more than a standard project. Schools and nonprofits are willing to make that investment. But the formula gets more complex with private development. Adding to the complexity, Skanska is aiming for its project rents to be market rate.

Chris Rogers of Bullitt’s development partner Point32 says Bullitt's space will be market rate too, though it's being marketed towards environmentally-minded businesses and organizations. The Cascadia Green Building Council is one tenant. For these organizations, the environment is a critical part of what they do. For Skanska's more mainstream tenants, locating in a living building says they care. But Skanska's also got to do more convincing.

In this DJC article from last June, Peter Busby of Vancouver's Busby Perkins + Will said it cost his team $100,000 to go to living building status on two Vancouver projects. He said it generally costs $40,000 to have a project certified LEED gold. The Bullitt Center project is costing about $30 million, with Bullitt putting up half that amount and borrowing the rest from US Bank. Rogers of Point32 says a lot of the cost is a first-cost premium, because it’s the first time his team (or any team) is moving through a living building project of this size with the city. But there’s still a premium.

According to the International Living Future Institute, it costs $20,000 for living building certification of a building that is between 107,640 and 538,195 square feet.

Skanska’s project is also interesting because of what it could bring to the neighborhood. The end of Stone Way near Lake Union has a handful of stores but is kind of a dead zone. In a Seattle Times story, Ryan Gist, a neighbor called it "an odd, pseudo-industrial street that really doesn't do much for the neighborhood."

Once complete, the ground floor of this building will house Brooks' first ever retail concept shop. The goal is for the shop to act as a gathering place for the community and trail users.

There are some neighborhood concerns about the structure's height. Here's hoping a clean agreement can be made on that topic so this revolutionary project can move forward.

By the way, back in January, I wrote this post about the launch of Skanska's Seattle commercial development division. In it, I said:

"I'm curious to see what kind of projects they pursue, what kind of sustainable goals they target, and what kind of green technologies they might choose to pursue that others wouldn't be able to. Of  course, they could simply go the LEED gold route. Or they could build something really innovative."

I don't want to say I told you so but it's fair to say this project falls to the later half of that spectrum. Now the question is to see how it plays out.

P.S. It's interesting to see the architecture firms with living buildings under their belts. This project is being designed by LMN. Bullitt's is designed by Miller Hull. The Bertschi project was designed by members of KMD Architects. I'm going to be waiting to see how long it takes for the area's other big green architecture firms to add a living building to their project list. At the current pace, I'd bet we'd see another two or three pop up.

Bill Gates says technology holds the key to energy, climate. What do you think?

Posted on May 11, 2011

When we're talking about solving big problems there is a division between those who believe new technology will hold the key and those who believe things need to change now, even if we don't have the perfect tools. That division was highlighted at yesterday's talk on energy and climate by Bill Gates.

Bill Gates, former Microsoft CEO and co-chair of the Bill & Melinda Gates Foundation, spoke at Climate Solutions' annual breakfast May 10. Our story on his talk is here and there are

Image courtesy The Seattle Times
multiple other articles and accounts on the web. Gates basically said what he's said before: we need major technological breakthroughs to solve climate and energy problems. To do this, he said the government needs to spend more than double the amount it currently does on research and development, and the private markets will follow. By breakthroughs, he means far-out technologies that will create a zero or very low carbon energy source. More money should be spent on renewable energy, carbon sequestration and nuclear energy, he said.

“The thing I think is the most under-invested in is basic R&D,” he said. “That's something only the government will do. Over the next couple of decades, we have to invent and pilot, and in the decades after that we have to deploy in an unbelievably fast way, these sources.”

But even during the breakfast, this division between work in the future and work now was felt. Dean Allen, CEO of McKinstry, spoke before Gates did. He said technological silver bullets are great but "it's often not best to wait for superman. It's sometimes better to figure out how to take practical and profitable real time solutions where we live."

Image courtesy Climate Solutions
Allen has a guest post on the Climate Solutions Blog here, if you're further interested in his ideas. To watch Gates' TED talk on a similar topic, go here.

Later, in a briefing with journalists, KC Golden, Climate Solutions' policy director, said he doesn't think all our problems will be solved by public funding. Public money isn’t a panacea, he said, but it is a critical piece of the solution for the energy sector “because the way the regulated economy works starves the energy sector of R&D money and innovation.”

If we are going to solve the energy and climate problems, what do you think we should be concentrating on - innovation or current work? Of course, the true solution would and most likely will (if we find it) include both. But which area do you think deserves more attention?

Canadian Building aims to be greenest in North America

Posted on April 27, 2011

Living Future 2011 in Vancouver, B.C . could have begun better. My first event was a tour of the new Centre for Interactive Research on Sustainability space at University of British Columbia.  To get there, all 30 of us had to wait 20 minutes, get on a 40 minute bus ride and then trudge through 15 minutes of pouring, pouring rain. Needless to say, I should have remembered my umbrella. A kind soul on the tour (not from the Northwest, obviously, who

The inside of the CIRS building, as it looks today
DID remember her umbrella) gracefully let me half-hover under hers. Despite that, I am currently totally soaked through though my shoes and coat are now drying out.

Thankfully, the tour was totally worth it. The CIRS Center is poised to be an incredible project, once complete. The four-story, 60,000-square-foot dry-lab research building has targeted both the Living Building Challenge and LEED platinum. Its goal is to be the most innovative building in North America. The building should be ready for occupancy by the end of May. It was designed by Busby Perkins + Will.

When designing and building it, the team concentrated on equally balancing the need to be net positive, or to give back more energy and environmental benefit than the building took from the grid; to be humane, or being constructed and thought of with the best impacts on humans possible; and being smart, or cost effective and adaptive.

The inside office space of the new CIRS building. It is shaped like a horseshoe.
To do that, this building functions on a greater scale than just its footprint in two big ways. It captures wasted heat from the building next door and uses some of it to fully heat the CIRS building before giving the rest back. Doing this allows the building next door to reduce the amount of steam it requires for heat, which reduces money the university spends on natural gas, saving money and creating a net positive effect.

It will capture all rainwater, treat it and use it as potable water for those in the building to drink (this is what the Bullitt Foundation's Cascadia Center targeting living building status in Seattle wants to do, though code rules are making it tough). It will also treat all wastewater generated in the building and use it to flush toilets, urinals and for drip irrigation. This was a difficult thing to permit, said Alberto Cayuelo, associate director of the UBC Sustainability Initiative. All water will be treated, drank, reused, treated, reused and treated again. This is the first building in Vancouver, the team said, to do this. Water that hits the building's hardscapes will be redirected into the aquifer.

The building's price is $37 million Canadian, with a $22 million construction budget. Cayuela said the project will cost between 20 and 30 percent more than a LEED gold building.

“I’d be lying through my teeth if I said this building came in at no premium,” he said. “(But) on a total cost of ownership basis, we can recoup that investment in a few years.”

The project should save money through energy and water initiaves.

There’s a lot more that I can and will say about this project. But I’ m about to hear Majora Carter speak, so more info will have to wait for another story!
