Grocery stores are among the most energy-intensive commercial buildings, consuming two to three times as much energy per unit floor area as office buildings. The single-largest energy end use component of grocery building consumption is refrigeration. In current practice, most of the energy extracted from refrigerated cases and walk-in coolers is rejected to the outdoors. Significant gains in efficient operation of grocery stores can be achieved by recovering this rejected heat to meet various lowgrade heating requirements within the stores. The recent Advanced Energy Design Guide for Grocery Stores: Achieving 50% Energy Savings Toward a Net Zero Energy Building1 offers a number of ways the design of the refrigeration and HVAC systems in grocery stores may be integrated to achieve this savings.
