We use the U.S. Green Building Council's (USGBC) Leadership in Energy & Environmental Design (LEED) rating system to guide best practices in the design, construction and operations of our stores and corporate facilities. LEED is a nationally recognized benchmark for high-performing green buildings. We focus on three LEED rating systems: LEED for New Construction, LEED for Existing Buildings: Operations & Maintenance and LEED for Commercial Interiors. To be LEED-certified, a building must meet criteria set by the USGBC. LEED-certified buildings conserve natural resources, reduce operating costs and minimize strain on local infrastructures.
