The U.S. Department of Energy (DOE) and the National Renewable Energy Laboratory (NREL) have released the first technical support documents providing recommendations on how to achieve 50% energy savings over the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) Standard in grocery stores and medium-sized retail buildings.
The reports found that achieving 50% energy savings is possible for medium-sized retail buildings with plug load levels no greater than 1.76 watts per square foot and for grocery stores in each climate zone in the United States. According to the reports, the 50% goal can be met without photovoltaic electricity generation.
The studies support DOE’s goal of producing market-ready, net-zero energy commercial buildings by 2025. They follow the August launch of DOE’s Net-Zero Energy Commercial Building Initiative and the National Laboratory Collaborative on Building Technologies, which focuses scientific expertise and resources of five national laboratories toward reaching the goal.
The technical support documents are available on the NREL Web site.
