Wind turbines, geothermal wells, reuse of coil condensation water and a central heat pump water heating system are among the measures used in the five buildings that received ASHRAE Technology Awards.
The awards recognized achievements by members who have successfully applied innovative building design while incorporating standards developed by the American Society of Heating, Refrigerating and Air-Conditioning Engineers for effective energy management and indoor air quality.
Benjamin A. Skelton, president of Cyclone Energy Group in Chicago, received first place in the new commercial buildings category for a zero energy building Walgreens store in Evanston, Illinois.
It features include 840 roof-mounted solar panels; two 35-foot-tall wind turbines; geothermal green HVAC; LED lighting and daylight harvesting; carbon dioxide refrigerant for heating, cooling and refrigeration equipment; and energy-efficient building materials.
DPR Construction San Francisco office
Dylan T. Connelly an associate with Integral Group of Oakland, California, received first place in the existing commercial buildings category for its work on DPR Construction’s San Francisco office.
The office was made net-positive by reducing energy loads through use of efficient green HVAC and electrical systems, and by installing photovoltaic and solar thermal systems on the roof to produce more energy than the building consumes. By retrofitting an existing building instead of building new, the project reduced its initial carbon footprint by over 70 percent, officials say.
Anne-Marie Edward Science Building at John Abbott College
Nicolas Lemire, president/principal at Pageau Morel and Associates in Montreal, received first place in the new educational facilities category for the Anne-Marie Edward Science Building at John Abbott College in Sainte- Sainte-Anne-De-Bellevue, Quebec.
The building makes use of green HVAC such as geothermal wells, electrical heating and cooling, natural gas hot water heating and solar preheating. Potable water consumption is reduced with the use of low-flow plumbing fixtures and resources are maximized through the re-use of return air as compensation air in laboratories and of coil condensation water to humidify exhaust air.
Ken Warren, capital project manager at the Port of Seattle, received first place in the new industrial facilities or processes category for the Sea-Tac Airport pre-conditioned air project.
The system includes an air plant that delivers sub-cooled glycol/water through 15 miles of piping to each of the 73 airplane gates in the existing facility, which allows airplanes to shut off their jet-fueled on-board auxiliary power units, saving fuel and reducing in carbon dioxide and other gas emissions.
Stack House apartments
Jonathan M. Heller, a principal engineer with Ecotope Inc. in Seattle received first place in the residential category for the Stack House apartments.
Innovative mechanical systems include a central heat pump water heating system in the largest of the two multifamily buildings, ductless heat pumps for 40 percent of the apartment units and common spaces, and rainwater catchment and reuse for urban agriculture on the roof, ASHRAE said.
