Construction of new energy efficient buildings is the most cost-effective way to achieve an energy efficient infrastructure over the course of time. Activities to encourage energy efficient construction include promoting the use of effective energy building codes, LEED certification and other high energy efficiency rating systems, and supporting activities and publications.
The Energy Office maintains a list of Energy Conservation Measures (ECMs). This list includes common ECMs that are known to reduce energy consumption, either independently or as part of a system with efficiency optimized. All purchases of appliances and commercial equipment must meet or exceed the minimum federal standards for energy efficiency, which can be found on the US Department of Energy website and at ENERGY STAR®.
In addition, the 2009 International Energy Conservation Code (IECC) is a good reference for energy-conserving products and projects.
Questions regarding applicable building code requirements, inspection, or enforcement should be referred first to your local building inspector and then to the South Carolina Department of Labor, Licensing, and Regulation.
