NEW YORK — Safeway’s store in the Georgetown section of Washington, D.C., has earned Leadership in Energy and Environmental Design certification from the U.S. Green Building Council. The 71,067-sq.-ft. store is the grocer’s second LEED-certified store and the first LEED-certified store in D.C.
The store’s green building elements include sunshade screens to reduce solar heat gain and a storm water drainage system that collects and filters on-site runoff from the parking lot and roof. The store also features water-efficient landscaping, including the use of drip irrigation with a landscape irrigation system water diverted from public sewer system by reuse of defrost waste water. Drought-tolerant native plants that require little or no irrigation help reduce the use of water.
Additional sustainable elements include:
White “TPO” roofing, which reduces the heat island effect and decreases cooling requirements for the store;
LED lighting in exterior signs, which reduce energy consumption by 80% or more compared with standard neon signs;
No CFC refrigerants. Safeway exclusively uses R-507 in its refrigeration systems, an HFC refrigerant with low ozone depletion potential;
Protocol-distributed refrigeration systems, which places the compressors closer to the various loads around the store to reduce the amount of copper piping in one store by about 35%. It also reduces the refrigerant charge by approximately 30%; and
Centralized HVAC system, using R-410a, which is more energy-efficient than R-22 and has zero-ozone depletion potential.
The Georgetown Safeway reopened last year.
