McKinstry is recognizing the Lake Washington School District as a “model of Northwest sustainability and environmental stewardship,” with its Champion of Sustainability award.

The district was honored during the Sept. 27 Seahawks game at CenturyLink Field.

In partnership with the Seattle Seahawks, the annual Champions of Sustainability program recognizes one organization during a regular-season home game that exhibits  innovative energy and waste reduction in the built environment.

What did they do?
In 2006, LWSD adopted a resource conservation management  program focusing on energy efficiency, water conservation and waste reduction. Since then, the district has saved $9 million in utility costs despite having increased its buildings’ square footage and number of students.  Electricity use has fallen by 20 percent and natural gas consumption is down 30 percent. Conservation-minded students also helped trim the district’s waste disposal budget by 42 percent.

LWSD also has the largest solar energy capacity of any school district in the state, at 615 kW – enough energy to power about 60 homes. The solar panels at Finn Hill Junior High alone account for 355 kW.

Geothermal heating systems have been installed in its new high schools and several elementary schools. Because the temperature underground stays constant throughout the year, geothermal systems that circulate water through the ground can heat schools using much less energy than standard systems.

Rain gardens and other sustainable stormwater management practices at schools save LWSD $64,000 annually, as compared to traditional water treatment systems. The measures also reduce the concentration of pollutants funneled into local waterways.

Last year, the district renewed its commitment to sustainability by launching powerED, a behavior-based program designed to bring new levels of effort and tools to conserve utilities, increase efficiencies and promote sustainability in LWSD schools.

NFL strikes gold with new 49ers’ stadium

Levis StadiumThe new home of the NFL’s San Francisco 49ers has achieved LEED Gold status, a first for an NFL stadium. Levi’s Stadium in Santa Clara, California, has many green features, including a green roof, solar-paneled pedestrian bridges and a solar-paneled roof deck. But, its most crucial green feature may be the state of the art grey water system.

Up to 85 percent of all water used in the 68,500-seat stadium comes from recycled water. A recycled-water pressure booster system taps into the Santa Clara Valley Water District water recycling system, eliminating the need to use freshwater to flush toilets and irrigate the natural grass field and green roof.  The system is powered by Bell & Gossett brand pumps.

“A recycled-water pressure booster system ensures adequate water is available when everyone goes to the bathroom at one time, like halftime at a football game,” said Mark Handzel, Vice President, Product Regulatory Affairs, and Director, HVAC Commercial Buildings.

The stadium’s water assessment estimates the recycled-water pressure booster system will save over 42 million gallons of water per year. And there are twice as many toilets in Levi’s Stadium as were in Candlestick Park, the 49ers’ former stadium.

The stadium uses highly efficient building systems by Bell & Gossett, including:

  • The centrifugal pumps were selected for the recycled-water pressure booster system.
  • The Rolairtrol air separators, Series 60 inline pumps, 1510 end suction base mounted pumps, and VSX double suction pumps were chosen for the hydronic systems.
  • A brazed plate and GPX gasketed plate, and frame heat exchangers were selected because of their high thermal efficiency for the condenser water system.

The Levi’s Stadium will host Super Bowl 50, next year, on Sunday, February 17, 2016.

Need a building? You’ve got some new options

The following post is by Alaska Structures:

Much has been said about sustainable construction methods and how beneficial reclaimed and recycled materials can be to reduce the carbon footprint of a home or commercial construction project.  However, often overlooked are the many non-traditional building alternatives that provide an energy efficient shortcut to a complete building.

Shipping Containers

shipping container

Highly durable and too often wasted, these hulking containers aren’t just for subterranean bomb shelters anymore. DIYers and construction experts have been creating beautiful, functional, and livable buildings out of industrial shipping containers for several years now and we’re thrilled with the results.

By reusing the massive metal containers for home construction, homeowners are able to enjoy sturdy walls, cool interiors, and endlessly expandable layouts. While working with standard shapes may feel limiting, many experienced container builders have found ways to create ventilated rooftops and innovative, expansive rooms using multiple container sections, as well as beautiful outdoor decks and living spaces.

While it takes a lot of hard work and logistical planning, the benefits of designing a custom home without the need for producing additional materials will provide a level of satisfaction beyond what typical sustainable building practices often provide.

Tensioned Fabric Buildings

tensioned fabric building

Perhaps some of the most versatile structures available today, a high-end tensioned fabric building can sometimes outperform even a brick and mortar structure in terms of durability. These buildings can withstand significant snow load and high winds, will remain intact during natural disasters, and help lower insurance costs.

High-end fabrics can provide insulation and security in any climate on earth and some manufacturers go the extra mile with HVAC systems, electrical connections, and other custom options. The lightweight nature and ease of installation make these fabric buildings a great option for organizations on the move, but with so many foundation options, there’s no reason why you can’t install your fabric structure in place for good.

Worried about meeting building code? Depending on where you purchase your fabric building, the company’s engineers may be able to meet or exceed various building code requirements mandated by your city or state governments.

Modular Buildings

modular building

Shedding the misnomer of “pre-fab” buildings, modular constructions aren’t just for the temporary construction site, and are not like the double-wide trailers of 40 years ago. Entire hospitals, apartment complexes, and even hotels are being built using modular practices. By using modular methods, major projects have found success with reductions in construction time, site preparation, and shipping costs.

The production of modular buildings is more efficient, so they are a much more eco-friendly solution when compared with traditional construction. The construction industry accounts for about 40% of the energy consumption and greenhouse gas emissions in the United States. By using off-site manufacturing methods, the UK’s Waste & Resources Action Programme suggests that construction site waste can be reduced by as much as 90%. Off-site construction also requires less heavy machinery use during the assembly process, further reducing emissions during the construction.

Modular buildings aren’t just greener during construction either – many modular constructions come with super efficient HVAC systems, zero volatile organic compounds (VOCs), and glass walls/open office layouts that utilize more natural light.

Alaska Structures has manufactured fabric buildings for industrial and commercial applications around the world since 1975.

See the Super Bowl in a whole new light: LED

The following post is by Ephesus Lighting:

It’s not the first time a championship football game will be played at University of Phoenix Stadium and the two teams will not be there for the first time. But for the first time ever, the big game will be illuminated by high performance LED stadium lights from Ephesus Lighting,  which provides LED lighting for sports facilities.

Earlier this season, University of Phoenix Stadium became the first NFL venue to light its playing surface with LED lighting. Ephesus reports the lights have been a hit with fans, players, broadcasters and facility operators.

“This year LED sports lighting proved to be ready for primetime as we illuminated more than 1,000 sporting events with our Ephesus LED stadium and arena lights,” said Mike Lorenz, President of Ephesus Lighting. “It’s fitting that the biggest sporting event in the world will be lit by our LED lights, the future of sports lighting.”

City of Glendale

The new LED fixtures at University of Phoenix Stadium slash energy use by 75 percent.

Ephesus fixtures, which are powered by Cree LEDs, provide an increase in illumination compared to the traditional metal halide lights that were previously installed at University of Phoenix Stadium. LED lighting also provides brighter and more uniform light which eliminates shadows on the playing surface, creating a better stage for players and fans, both in the stadium and watching on high-definition television.

The Ephesus installation is well-suited to HDTV broadcasting and feedback from broadcasters this season has been positive. Not only is the light brighter and more uniform across the playing surface, but the new lighting ensures that colors are reproduced more accurately. Since broadcasters do not need to open the camera’s aperture as wide to let in more light, they can present a clearer picture, show greater field depth, zoom in closer and even offer more detailed slow motion replays.

“The capabilities of LED technology have changed the way we view sports lighting,” said Joe Casper, Founder and CTO of Ephesus Lighting. “There is no doubt in our minds that both the fans in the stadium and millions more watching on television will see the game in a whole new light thanks to our ground-breaking system.”

University of Phoenix Stadium installed 312 Ephesus Stadium fixtures to replace the 780 metal halide fixtures. The new system uses just 310,000 watts of energy as compared to the 1.24 million watts needed to power the previous system for a 75% reduction in overall sports lighting energy consumption.

Additionally, LED lights can be turned on and off with the flick of a switch, whereas metal halide fixtures require a 20-minute warm-up period. This on/off feature allows facility operators to create light shows for fan entertainment, and, if a power outage were to cause a blackout, like it did in 2013 at the Superdome, the LED lights can be turned back on immediately with the flick of a switch.

“As the host venue for the 2015 Super Bowl, we are excited about demonstrating the benefits of LED technology to a global audience,” said Peter Sullivan, General Manager and Regional Vice President for Global Spectrum at University of Phoenix Stadium. “The Ephesus Lighting LED solution has improved lighting for the athletes, fans and broadcasters, all while reducing energy consumption and eliminating conventional sports lighting maintenance expense.”

The University of Phoenix Stadium has a retractable roof and field. The multi-purpose facility, which opened on August 1, 2006, previously hosted Super Bowl XLII in 2008, two BCS National Championship Games (2007 & 2011), the annual Fiesta Bowl, and numerous international soccer matches. The 63,400-seat stadium, which is expandable to seat 72,200 fans, is owned by the Arizona Sports and Tourism Authority (AZSTA) and operated by Global Spectrum.

Since lighting the first sports venue with LED technology in North America in 2012, Ephesus Lighting luminaires have been operational for over 300,000 hours in more than 100 indoor and outdoor sports and entertainment venues across North America.

Ephesus Lighting is a Syracuse, New York-based company that manufactures high-output LED lighting solutions for the industrial and sporting markets.

McKinstry honors its favorite teams

McKinstry, Avista Corp

Front row: Dan Thompson (McKinstry) Back row (left to right): Paul Zasada (McKinstry), Dennis Vermillion (President of Avista Utilities); Scott Morris (CEO & President and Chair of the Board, Avista Corp); Dean Allen (CEO McKinstry), Mireya Fitzloff (McKinstry), Eric Bowles (Avista Head of Facilities) and Rod Staton (Avista Facilities).

McKinstry is honoring its clients for their commitment to sustainability. Each is called a “Champion of Sustainability” and is presented with an award at a Seahawks home game.

The next winner, The Allen Institute for Brain Science, will be honored at the November 2nd Seahawks game against the Raiders. The award goes to Vulcan Real Estate, GLY Construction, Perkins+Will Architects, and Architectural Building Inspection (ABI) Inc. This energy efficient, design-build project has a central plant system that is designed to perform 24% better than the ASHRAE standard.

Recent winners of the prize include Avista Corp. for its corporate headquarters and the U.S. General Services Administration (GSA) for the Thomas Foley U.S. Courthouse.

McKinstry said the five-year remodel of Avista Corp.’s 150,000-square-foot office building will save 1.4 million kilowatt-hours per year, which is enough to power 116 homes, and will save $149,000 every year in energy costs. This LEED Gold Certified project will be completed by the summer of 2015.

The Thomas Foley U.S. Courthouse project dealt with the unique constraints of providing extensive upgrades to an existing building. The upgrades reduced baseline energy consumption by 50 percent, and reduced carbon emissions by 693 tons.

Other 2014 Champions are Vulcan Real Estate, GLY Construction, Clise Properties, Lydig Construction, Seattle University, Gresham-Barlow School District.

One of the largest solar arrays in the state of Washington is included in McKinstry’s many energy conservation initiatives at CenturyLink Field and Event Center.

Here are some other conservation facts about CenturyLink Field:

  • Solar panels spanning the area of two football fields sit atop the roof and generate more than 800,000 kilowatt hours of electricity annually, meeting 30% of the facilities energy needs with solar power, an equivalent of powering 95 Seattle area homes for a year.
  • 100% of urinals have been retrofitted with ultra-low-flow water fixtures, saving more than 1.3 million gallons of water every year. That’s enough to turn CenturyLink Field into a giant 3-foot-deep swimming pool.
  • Less water means less energy and lower CO2 emissions – the equivalent of planting 278 football fields worth of trees.
  • Through the use of 614 recycle and compost bins located throughout, 94% of waste generated at CenturyLink Field and Event Center is diverted from landfills.

How green is the future? Yudelson’s 2014 predictions

The following post is by DJC staff:

Sustainability consultant Jerry Yudelson, has released his annual list of the top 10 green building trends and says he expects this year will see a rapid increase in energy retrofits on existing buildings, a new focus on water conservation, and a switch to cloud-based systems for monitoring and managing energy use.

Jerry Yudelson

He says the expansion will be global thanks to the economic recovery in most of Europe and North America. “There is no doubt that we are seeing more agencies, architectural firms, development organizations and companies building green each year,” he writes, “and there is nothing on the horizon that will stop this MegaTrend or its constituent elements.”

By the way, Yudelson also announced he is the new president of Green Building Initiative, the organization responsible for the Green Globes green building rating and certification system that he says is increasingly competing with LEED.

Yudelson Associates’ Top 10 Green Building MegaTrends for 2014

  1. Green building in North America continue its strong growth in 2014, with the ongoing expansion of commercial real estate construction together with government, university, nonprofit and school construction. This will build on the fact that in 2013 green building project registrations in new construction accounted for about 30% of all new projects.
  2. In 2014, there will be rapid uptake of energy-efficiency green building retrofits.. Note: this trend will be strongest in corporate and commercial real estate, along with the “MUSH” market (Municipal, University, School and Hospital) projects, given the availability of cheap financing and the rise of numerous new players in the building energy retrofit market. Yudelson says absolute building performance, and resultant operating cost, (vs. the relative improvement approach still enshrined in most rating systems) is going to be an increasing focus for building owners.
  3. Zero-net-energy buildings are become increasingly commonplace, in both residential and commercial sectors. LEED and ENERGY STAR certifications and labels have become too commonplace to confer competitive advantage among building owners. Developers of speculative commercial buildings have also begun to showcase Zero Net Energy designs in order to gain marketplace advantages. Systems such as the Net-Zero Certification of the International Living Building Institute are driving this trend, but it has been growing steadily for about five years.
  4. LEED will see enhanced competition from Green Globes. This trend is supported by the fact that the Federal government has released its “once every five years” assessment of rating systems and has now put the two systems on an equal footing for government projects. More importantly, LEED will struggle to convince owners, designers and consultants in all sectors that LEED v4 represents more value than hassle.
  5. The focus of the green building industry will continue its switch from certifying new building design and construction to full greening of existing buildings. This trend has been in place since 2010, and we expect it to accelerate in 2014.
  6. Green Buildings will increasingly be managed by information technologies, especially those in the “Cloud.” This trend is reflected by the large number of new entrants and new products in fields of building automation, facility management, wireless controls and building services information management over the last three years. In fact, we are calling 2014, “The Year of the Cloud” for how quickly this trend will become fully established.
  7. Green Building Performance Disclosure will continue as a major trend. This is highlighted by disclosure requirements enacted in 2013 by more than 30 major cities around the country, laws that require commercial building owners to disclose actual green building performance to all new tenants and buyers and, in some places, to the public. This trend will spread rapidly as the easiest way to monitor reductions in carbon emissions from commercial and governmental buildings.
  8. Healthy Building Products, Product Disclosure Declarations, along with various “Red Lists” of chemicals of concern to healthy building advocates, will become increasingly contentious. This trend has manifested through such tools as the Health Product Declaration and the inclusion of points for avoiding certain chemicals contained in LEEDv4, currently scheduled for full implementation in 2015. We predict that building product manufacturers will increasingly try to gain or maintain market share based on open disclosure of chemicals of concerns. We also foresee that industry-developed disclosure systems will begin to compete with systems offered by dozens of third-party rating agencies.
  9. Solar power use in buildings will continue to grow, especially because of the prospect of increasing focus on implementing aggressive state-level renewable power standards (RPS) for 2020 and the move toward zero-net-energy buildings. As before, third-party financing partnerships will continue to grow and provide capital for larger rooftop systems on low-rise commercial buildings, parking garages, warehouses and retail stores, as well as on homes.
  10. Awareness of the coming crisis in fresh water supply, both globally and in the U.S., will increase as global climate change affects rainfall and water supply systems worldwide. Leading building designers, owners and managers will be moved to take further steps to reduce water consumption in buildings by using more conserving fixtures, rainwater recovery systems and innovative new onsite water technologies.

BIG’s hilly courtyard tops a new gym

The following post is by DJC staff:

The Danish architecture firm BIG with CG Jensen + EKJ + Grontmij said it has completed a new multipurpose hall for Bjarke Ingels’ former high school north of Copenhagen. The project turned a courtyard into a new gathering point above an underground sports facility.
The space can be used for sports, graduation ceremonies and social events.

Architect Bjarke Ingels says he considers the roof a giant piece of informal furniture.

BIG said in a press release the new hall is 16 feet below grade to ensure a good indoor climate and reduce its environmental impact. It is formed by beveled concrete walls and covered by a vaulted wooden roof made of curved glued laminated timber beams.

The roof functions as an interior and exterior skin, creating a hilly courtyard that can accommodate a number of activities from group work to larger gatherings.

The exterior surface is untreated oak and white enamel-coated steel benches that were designed by BIG. The only light sources at night come from the benches and seating, which are outfitted with LED lights underneath that brighten the entire courtyard.

The edge of the roof is a long bench with a lattice design that brings in daylight below. Solar panels around the buildings heat the hall.

Bjarke Ingels said, “Rather than placing the hall outside the school — and spread the social life further — we have created a new focal point and link between the school’s existing facilities. The roof forms a molehill that serves as a giant piece of informal furniture engaging and supporting student life.

“The main architectural idea emerged from the rules of handball as the soft, curved roof takes its form from the mathematical equation of the trajectory of a thrown ball. Form follows function. In an homage to my old math teacher, we used the mathematical formula for a ballistic arc to shape the geometry of the roof.”

A future phase will connect the courtyard and hall with sports fields and parking, and provide space for art classes and cultural activities.

BIG — Bjarke Ingels Group — describes itself as an international partnership of architects, designers, builders and thinkers operating within the fields of architecture, urbanism, research and development.

The next big thing in energy conservation? Small commercial buildings

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.

Your patio can also be a power plant

The following post is by Silicon Energy:

Two Washington-based companies said they are joining forces to make solar systems easier to install and more flexible than traditional roof- or ground-mounted modules.

Silicon Energy, a solar photovoltaic (PV) manufacturer, and CrystaLite, a skylight and sunroom manufacturer, will create pre-engineered, integrated-PV systems. The new structures — including patio and carport coverings, electric car charging ports, and picnic shelters — will let solar contractors offer customizable, durable PV systems.

Silicon Energy said the modules are strong enough to withstand harsh weather and were recently rated the most durable among competitors by the federally funded National Renewable Energy Laboratory.

They were introduced at the recent Living Future’s unConference in Seattle.

PV systems can be installed on different types of structures.
The structures are offered in modular 4-foot widths, and can incorporate CrystaLite railing systems with glass panel, aluminum pickets or stainless steel cable railings. Silicon Energy and CrystaLite PV-integrated structures can be grid-tied or battery-backed to generate electricity in remote locations.

Silicon Energy said its double-glass design allows light transmission through the PV module with a mounting system that fully encloses and protects the system wiring, delivering an aesthetically pleasing and practical shelter. The open-framed, shingle-like mounting of the Cascade Series PV Module and Mounting System maximizes shedding of snow, dirt and debris from the modules, which optimizes performance.

Silicon Energy’s modules come with a 30-year power warranty, a 125-psf load rating and Class-A fire safety rating.

“A paradigm shift is needed in how we look at PV,” said Silicon Energy President Gary Shaver. “We need to think beyond the roof and fields and integrate PV even more into our local communities, bringing the beauty and benefits of distributed generation of PV into our built environment.”

The systems will be available starting in July.

Silicon Energy was founded in 2007 and is located in Washington and Minnesota. More information is at

Founded in 1982, CrystaLite is a Washington-based manufacturer of roof glazing, sunrooms and railing systems that are built by local employees. Primary vendors are in Portland and Hood River, Ore., and the company says 80% of its raw materials are from Washington and Oregon. For more information about CrystaLite, Inc., visit
