Energy-efficient buildings are central to modernizing U.S. infrastructure

  If roads, bridges, and phone and transmission lines are the veins of American infrastructure, buildings are the heart. Whether residential or commercially owned, the buildings that serve as places of work and living in the United States unquestionably shape public health, safety, and economic productivity. As buildings’ multiplying energy needs increasingly force their integration into the United States’ energy grid, it has become necessary to update building practices and technologies accordingly. These updates should minimize energy leakage and make greater use of each unit of energy consumed.
