House Multifamily Renovation Light Commercial Communities Technical Guidelines Version 1.0 November 30, 2011 Version 1.0 - 1 - ECLC Technical Guidelines THIS PAGE LEFT INTENTIONALLY BLANK Forward The EarthCraft Light Commercial (ECLC) Program was developed by Southface in early 2007 in response to requests from a largely underserved market of small-scale commercial buildings. Expanding EarthCraft to meet the needs of this market was an appropriate evolution of the program and supported Southface’s commitment to promoting sustainable homes, workplaces and communities. EarthCraft Light Commercial began as a pilot to evaluate the need for a green building program focused on the specific requirements of small scale commercial building projects. Participating pilot projects in Georgia, South Carolina and Virginia provided invaluable insight into the development of the new EarthCraft Light Commercial Program. After the close of the pilot phase of development, the new EarthCraft Light Commercial Program was officially launched in November 2011.
