Assessment of energy performance and design level savings

Minnesota Sports Facility Authority (MSFA) contracted with Willdan to complete a one-year assessment of US Bank Stadium energy performance and achievement of design level savings. US Bank Stadium is a 1.5 million square foot sport/event facility located in downtown Minneapolis. Willdan worked with MSFA to gather interval data for all utility streams to determine seasonal and event performance signatures. The study found that the buildings achieved 16% savings compared to energy code baseline operation during its first year of operation or approximately $870,000 which matched closely with the design expectations. The study uncovered potential areas of additional savings for MSFA to explore to build on these savings going forward.

High-Performance Building

"Energy strategies improve learning for children at Rocky Mountain Deaf School", a USGBC.org article, details how The Weidt Group (now part of Willdan), teamed with AndersonMasonDale Architects to incorporate energy-efficient strategies throughout the innovative, high-performance school in Denver and to pursue LEED certification.

"The three most prominent solutions—in-floor radiant heating and cooling, LED lighting and daylighting—are unique because not only do they save energy, but they also serve a distinct and direct benefit to the students themselves." For example, "temperature variance and excess air movement affect hearing-impaired students. The in-floor radiant system minimizes temperature variance and air movement, thus providing a better learning environment for the students." Read the full story at USGBC.org.
