Commercial Buildings as Clean Domestic Energy Assets by 2025? DOE’s Roadmap for a Net-zero Energy Built Environment

A net-zero energy building (NZEB) is a highly energy-efficientresidential or commercial building that, over the course of a year, usesrenewable technology to produce as much energy as it consumes fromthe grid. In the commercial sector, building owners and tenants stand torealize attractive returns on their NZEB investments while reducing theircarbon footprints. Considering that buildings are our nation’s highestenergy-consuming and carbon-emitting sector, NZEBs have a vital rolein reducing U.S. energy demand and greenhouse gas emissions (GHGs).This article outlines the U.S. Department of Energy’s (DOE’s) goalsfor the energy use by our nation’s commercial buildings, the researchand development (R&D) efforts most critical to realizing NZEBs, andDOE’s strategy of collaborating with the private sector to speed the ar-rival of NZEBs in the marketplace.
