Affordable, comfortable, environmentally friendly—the Passive House embodies the best in sustainable construction. Typically, buildings meeting the Passive House Standard use 80 to 90 percent less energy for heating and cooling, savings far greater than any other building standard delivers. For details on the schedule for each home, consult the listings below. All tours are free. Visitors may come anytime during the listed hours unless otherwise noted.

In conjunction with International Passive House Days, Earth Advantage, a Portland-based nonprofit focused on creating better buildings, will teach the Building Science Fundamentals module of its Sustainable Home Professional training series on Friday, November 13 and Saturday, November 14. Class members will tour some of the open Passive Houses. For more information and registration, visit www.earthadvantage.org/education/2321-259.

International Passive House Days is sponsored by the following organizations:

Earth Advantage:  www.earthadvantage.org
International Passive House Association:   www.passivehouse-international.org
North American Passive House Network:  www.aphnetwork.org
Passive House Northwest:  www.phnw.org

Lake Washington School District honored for sustainability

Champions of Sustainability: The Lake Washington School District: Forrest Miller, Traci Pierce, Brian Buck

Champions of Sustainability: The Lake Washington School District: Forrest Miller, Traci Pierce, Brian Buck

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.

About the Champions of Sustainability Program:
McKinstry’s Champions of Sustainability program is part of the Defend Your Turf campaign, aimed at water conservation, energy efficiency, waste reduction, and community involvement within CenturyLink Field and Event Cente,r as well as in terms of its impact on the city.

For more information on Defend Your Turf, visit www.centurylinkfield.com/defendyourturf.

About McKinstry:
McKinstry has implemented a number of facility-wide energy conservation initiatives at CenturyLink Field and Event Center, including the installation of one of the largest solar arrays in the state, mechanical system upgrades, high-efficiency lighting and ultra-low-flow water fixtures. These upgrades make the stadium a national model for sustainable sporting facilities.

McKinstry is a full-service, design-build-operate-and-maintain (DBOM) firm specializing in consulting, construction, energy and facility services.  For more information, visit  www.mckinstry.com.

There’s gold in your gray water

Along with a new age of sustainability comes new interest in gray water recycling and rainwater capture systems.  These systems capture water from your house’s bathroom sinks, showers and rainfall then reuse it to irrigate the lawn and flush the toilets.

The engineering behind the effort can be tricky, but in the simplest terms it goes like this: water from the “gray water sources” gravity-flows into a collection basin. A pump in the basin then pushes the water through a filter and disinfection array and into a storage tank.  The water in the storage tank is periodically circulated to keep it clear and bacteria-free. Finally, a pressure controlled pump automatically delivers recycled water to your irrigation system when your irrigation timer activates. It’s simplistically complex.

Whether on a household level or a commercial level, many have decided to invest in the water conservation effort.  Gray water recycling and rainwater capture systems can save 50 to 70 percent of a family’s monthly water usage. You’ll save that same 50 to 70 percent on your water bill.

How much does it cost to install? Do-it-yourself systems start at $3,500.  Systems for average sized homes start at $11,000.

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.
