[From Press Release] While commercial building owners generally have control over building systems and operations, tenants play a critical role in achieving lasting reductions in energy intensity. In recognition of this collaborative role, the Department of Energy has studied the feasibility of improving energy efficiency in tenant spaces. This study finds significant potential to improve energy efficiency during the design and construction of tenant spaces and describes several possible steps to encourage owners and tenants to improve the efficiency of those spaces.
