New module from Marysville solar manufacturer
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.
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
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.
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
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.
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.
You don’t need new windows to save energy and money
The following post is by Brad Kahn:
It’s a question many owners of older homes have asked: Should I replace my single-pane windows or refurbish them? With a torrent of direct mail selling new windows, many people are led to believe the best option to save money and energy is to replace the old windows with new.
Now a new report from Seattle’s Preservation Green Lab sheds light on an answer. And it may be a bit surprising.
The report, Saving Windows, Saving Money: Evaluating the Energy Performance of Window Retrofit and Replacement, concludes that adding storm windows and cellular shades can deliver essentially the same energy savings as full window replacement — at a fraction of the cost.
Applying 80 years of research using energy simulations, the research team found that saving and retrofitting old windows is the more cost effective way to achieve energy savings and to lower a home’s carbon footprint.
Nationally, home energy consumption accounts for 20 percent of total energy use, and Americans spent more than $17 billion on heating and cooling, so the potential impacts of the research are large.
This chart summarizes the key findings across cities and climate zones. The bottom line: Don’t assume you need new windows to save energy and money.
The Preservation Green Lab, a project of the National Trust for Historic Preservation, conducted the research, in partnership with Cascadia Green Building Council and Ecotope. It was funded by the National Center for Preservation Technology and Training.

25 islanders pitch in to put solar on Bainbridge City Hall
The following post is by Kathleen O'Brien:
In August, a 71.28 kW Community Solar Project installed on the roof of the Bainbridge Island City Hall went live. My husband and I are two of 25 Bainbridge Islanders participating in the project.
In a recent communication from Joe Deets, project manager and principal of Community Solar Solutions with his wife, Tammy Deets, we learned that despite a few initial inverter failures that have been quickly addressed, the system is actually performing better than average.
Jake Wade of Puget Sound Energy said, "The production at City Hall is higher than expected...A good south facing array will usually produce about 1000 kWh per year out of each kW installed. We typically see 120 kWh/kW in August. We show the array at 71.28 kW, so we'd expect 8554 kW out of your system. The Bainbridge Island array actually produced 9950 from 8/2 to 8/31."
Good news of course, but there's nothing "average" about this project. Our household invested in the project because it combines an opportunity to support our community using a sustainable technology and an innovative local investment model. Northwest SEED's website says, "Community energy brings a higher level of economic benefit to local communities than commercially developed projects. Various studies have attempted to quantify this additional benefit, and generally predict 2-5 times the economic benefit will be provided by a project with 100% local equity ownership, versus one owned by an out of area corporation...The actual impact will vary with every community and project, but generally the higher the local ownership stake, the greater the economic benefit to the local community."
It took several years for this project to come to fruition. The seed was planted during a community gathering organized by Joe and Tammy in 2005. But the enabling policy to make the investment possible and attractive to participants was not enacted until 2010 after years of lobbying by Washington State Senator Phil Rockefeller (also a Bainbridge Island resident).
Washington state’s Community Solar Enabling Act provides direct production incentives to owners of community solar projects up to 75 kW. The law grants community solar projects $0.30 for every kWh produced (twice the incentive for individual on-site production). Projects are eligible for incentive multipliers for using modules and inverters manufactured in Washington, encouraging local manufacturing as well as local ownership. To qualify for these community solar incentives, projects must be located on local government property, requiring innovative partnerships between governments, solar developers and community members interested in supporting solar power.
For the City Hall project, all of the above applies. The city of Bainbridge Island agreed to lease its roof (with its fabulous southern orientation) to the community-based investor group, in return for reducing the city's electricity costs (potentially by half). All 297 panels and 30 inverters are from the Bellingham manufacturer Itek Energy, making it Itek's largest single project to date. Seattle-based Sunergy Systems was the contractor selected to install the project.
Part of Community Solar's appeal is that even when you don't have the right site for solar, you can invest in a project that does. Ron and Ann Morford wanted to install solar cells on their roof, but shading from nearby trees foiled their plans. Instead, they were able to invest in the City Hall project because "it was a great way to make an investment in sustainable energy, partner with others from our community, provide much needed savings for our local government, and get a future return on our investment." For the Morfords, it was a "win-win-win" project. It also was a reasonably priced investment, affording participation by regular working folks, such as my husband et moi!
Hopefully this project has paved the way for more like it.
A kiosk will be installed soon in the City Hall lobby to provide information and up to date data on energy production. It will also be the first stop on the Bainbridge Island Solar Tour on Friday from 1 to 4 p.m. You can see the installation and ask questions. The 2012 Solar Tour is Saturday.

Chihuly offers lessons in green to 400,000 people a year
The following post is by Kathleen O'Brien:
In recent coverage of the new Chihuly Garden and Glass located at the Seattle Center, much has been said about art — both the art it displays and the dramatic artistry of the building design itself. While art is said to sustain the mind and soul, this particular building goes further, by employing sustainable techniques and taking the opportunity to educate its visitors as to their value.
In spite of a challenging design and an even more challenging schedule — 7 months to TCO — the project is slated to garner a LEED Silver Certification this fall. "LEED can be challenging even under normal circumstances," according to Jason Sturgeon, PM with Schuchart, the project's GC. "The aggressive schedule meant intense planning and coordination to assure that subcontracts were properly bought out and executed to follow guidelines imposed by LEED certification." Sturgeon adds that "it helped that there was significant harmony" between the players regarding implementing LEED.
In addition to Schuchart the team included Owner, Center Art, LLC, Development Manager Seneca Group, and Owen Richards Architect. (Full disclosure: O'Brien & Co. provided technical consultation on the LEED Certification process to the project team.)
When asked why make a fairly complicated project even more complicated, Seneca Group Principal Bob Wicklein cites the opportunity "to educate over 400,000 visitors expected each year about the environment and green construction."
As with many projects, a good percentage of the effort towards the LEED green building certification is not visible once the building is complete. Signage and tours will provide visitors with the story behind the story. Visitors will experience a lush garden but they will also learn that this area was formerly an acre of pavement. And those who "mourn" the Fun Forest" will be happy to learn that it has a second life — 100% of the Fun Forest exterior walls, roof, and floors were reused in the interior exhibition spaces, cafe, and gift shop.
Adapting rather than demolishing the old building not only kept tons of materials out of the landfill, it also saved the energy and water used to manufacture new materials and construct a new building. Overall, 97% of all the waste from construction of this project was diverted from the landfill, about 250 tons.
Signage will also point out that The Glasshouse, which was conceived as an indoor-outdoor space, is not fully heated or cooled in a conventional way. It uses natural systems to efficiently moderate temperatures while allowing the indoor temperatures to fluctuate along with outdoor conditions. Using high-efficiency boilers and chillers and other energy efficiency strategies, the rest of the building exceeds local energy code requirements. The restrooms feature low-flow fixtures that reduce water use by more than 30% over standard fixtures, saving an estimated 160,000 gallons of water per year in this building alone.
For each station on the tour, pertinent tips will be provided. One hopes that while every visitor will be inspired by the space and glass art to be creative, they will take some of that creative energy to green up their businesses and homes.

How a dashboard helps drive energy savings
The following post is by Tim Cox:
Lucid has partnered with the Seattle 2030 District to provide energy, water and transportation tracking to commercial buildings in downtown Seattle. As of June 2012, 103 buildings—representing over 29 million square feet of office space—have joined the Seattle 2030 District, a high-performance building district that aims for a 50 percent reduction in energy, water and transportation emissions by 2030.
Already, the District has seen substantial progress toward its goals:
• 8.4 percent energy reduction compared to the national average
• 2.3 percent water reduction
• 11.4 percent reduction in CO2 from transportation
To accurately track resource use and progress, participants are using Lucid’s Building Dashboard platform. This Web-based technology offers buildings owners and facility managers an integrated system for monitoring energy, water and transit data. Armed with improved transparency and goal setting facilitated by the Building Dashboard, building managers can engage tenants and occupants in a building’s conservation actions. Already, efficiency opportunities such as plug loads and behavior change—factors that have historically not been included in green-building initiatives— are being successfully implemented and measured.
Additionally, the Dashboard allows the District as a whole to track aggregated performance of all buildings. Energy and resource efficiency look very different at a building level than at a district or city scale. By focusing on improving the entire portfolio the District can focus its resources and initiatives on those that represent the best opportunities for improvement and associated payback. The District’s Building Dashboard also allows buildings to share data publicly and compare their building with its peers, adding an element of competition and knowledge sharing to the commercial building world.
