There is nothing small about the impact that small commercial buildings have on energy use in the United States. In fact, the 4.6 million small buildings across the nation consume 44% of the overall energy use in buildings, presenting an enormous opportunity to cut costs, energy use, and greenhouse gas emissions. Despite this potential, small building owners and operators face unique challenges that have historically impeded the adoption of widespread energy efficiency solutions. A new report developed by the National Renewable Energy Laboratory (NREL) examines these barriers and suggests a path forward to support cost-effective energy savings for the small buildings and small portfolios sector, which typically has limited resources to pursue energy efficiency solutions.

A net zero-energy community (ZEC) is one that has greatly reduced energy needs through efficiency gains such that the balance of energy for vehicles, thermal, and electrical energy within the community is met by renewable energy. Past work resulted in a common zero-energy building (ZEB) definition system of “zero energy” and a classification system for ZEBs based on the renewable energy sources used by a building. This paper begins with a focus solely on buildings and expands the concept to define a zero-energy community, applying the ZEB hierarchical renewable classification system to the concept of community. A community that offsets all of its energy use from renewables available within the community’s built environment and unusable brownfield sites is at the top of the ZEC classification system at a ZEC of A. (A brownfield site is where the redevelopment or reuse may be complicated by the presence or potential presence of a hazardous substance, pollutant or contaminant.) A community that achieves a ZEC definition primarily through the purchase of new off-site, Renewable Energy Certificates (RECs) is placed at the lowest end of the ZEC classification but is still considered a good achievement.
This report contains the findings from interviews with senior finance executives at retail companies regarding financial planning and capital budgeting strategies. The report and the supplementary key takeaways deliverable are meant to help energy and sustainability managers improve their relationships with the finance team and ultimately improve access to project financing. The interviews were conducted by the Retail Industry Leaders Association (RILA) and Deloitte Consulting LLP.
