Proposed legislation that would impose standards for building energy efficiency passed the House March 5. \tBy Senators Jeanne Shaheen (D-NH) and Rob Portman (R-OH), the Energy Savings & Industrial Competitiveness Act aims \u201cto speed transition to a more energy efficient economy,\u201d according to the senators. \tIt targets new homes and commercial buildings for upgraded standards. For manufacturing, it creates the Department of Energy-sponsored SupplySTAR program to make companies\u2019 supply chains more efficient. \tAlso for the government, the Office of Management & Budget would target efficiency technologies for federal agencies. An earlier version passed out of the Senate Energy & Natural Resources Committee but died on the floor due to unrelated, controversial amendments. \t Updates to earlier versions of the legislation include: \u2022\tRequiring federally backed residential mortgage loans to begin to account for the borrower\u2019s expected utility expenses. \u2022\tEstablishing a voluntary Tenant Star certification and recognition program to promote energy efficiency in leased commercial building space during design and occupancy. \u2022\tFacilitating retrofits for schools and leased commercial buildings. \u2022\tRequiring the Office of Management and Budget to collaborate with federal agencies to promote energy efficiency in data centers and other information technologies. On the other hand, it would repeal a requirement from earlier legislation calling for new federal buildings to achieve a zero-carbon footprint by 2030. \tThe proposed legislation is co-sponsored by six more Democrats and four Republicans.
