FROM THE AIA:
H-E-B at Mueller is an 83,587 square foot LEED® Gold and Austin Energy® Green Building 4-Stars retail store and fresh food market, including a pharmacy, café, community meeting room, outdoor gathering spaces, and fuel station. It serves 16 neighborhoods and is located in Mueller, a sustainable mixed-use urban Austin community. Strategies include a collaborative research, goal-setting and design process; integrated chilled water HVAC and refrigeration systems; the first North American supermarket propane refrigeration system; optimized daylighting; 169 kW roof-top solar array; electric vehicle charging; all LED lighting; and reclaimed water use for landscape irrigation, toilets, and cooling tower make-up water.
The jury was happy to see this type of program addressed. This prototype store rethought the energy and water use for a typical supermarket. The store replaced display ice with refrigerated cases, made extensive use of daylighting, and created a large entry vestibule that serves as a thermal buffer between the inside and the outdoors—important in a climate such as Texas.
