TECHNOLOGY AWARDS
ASHRAE Technology Awards recognize outstanding achievements by ASHRAE members who have successfully applied innovative building designs. Their designs incorporate ASHRAE standards for effective energy management and indoor air quality and serve to communicate innovative systems design. The Award of Engineering Excellence recognizes a first-place winner of the Society-level Technology Award competition for an outstanding application of innovative design and effective energy use. Technology Award-winning buildings will be featured in ASHRAE Journal this year.

ENGINEERING EXCELLENCE
TOBIHIRO KOSEI GENERAL HOSPITAL OBIHIRO, JAPAN
HIROKI YOKOYAMA, P.E.JP., MEMBER ASHRAEhe 10-story Obihiro Kosei General Hospital is located in the southeastern part of Hokkaido. which has the biggest outdoor temperature difference in Japan, approximately -22°C to 32°C (-7.6°F to 89.6°F). In this region, a conventional HVAC and domestic hot water heating system mainly using natural gas fuel is typically used in large hospitals, but this hospital has used innovative approaches to achieve a significant reduction of gas fuel consumption and carbon dioxide (CO2) emissions, including a high-performance building envelope, demand-control ventilation systems and exhaust air energy recovery systems.
FOREST EDGE ELEMENTARY SCHOOL FITCHBURG, WISCONSIN
FALEX HARRIS, ASSOCIATE MEMBER ASHRAE
orest Edge is a 127,000 ft2 (11 799 m2) elementary school located in the Oregon School District about 10 miles (16 kilometers) south of Madison, Wisconsin. Two years into operation, the school has exceeded expectations, with energy metering data to date showing annual energy production exceeding building energy use, going beyond net zero to net positive. Sustainability is incorporated into the school curriculum, with lesson plans available at each grade level on renewable energy and an educational initiative tasking students with learning hands-on about how to expand knowledge and make decisions on energy consumption.
LIBERTY MUTUAL–BOSTON CAMPUS BOSTON, MASSACHUSETTS
TKIERSTEN WASHLE, ASSOCIATE MEMBER ASHRAE, TERESA B. LAURENCE, P.E., MEMBER ASHRAE
he 22-story high-rise Liberty Mutual headquarters in downtown Boston operates at an energy use intensity (EUI) of 35 kBtu/ft2·yr (398 MJ/m2·yr)—a 60% energy reduction and $4.5 million in utility savings from the building’s baseline in 2014. The operational carbon footprint of the building was drastically reduced through continuous proactive commissioning focusing on finetuning building automation sequences. Innovative HVAC control strategies implemented included optimized ventilation control, solar reset for air-handling unit discharge air temperature and discretely staggering start time of HVAC equipment for peak demand reduction.
