The International Code Council (ICC) has announced the release of Public Version 1.0 of the International Green Construction Code (IGCC) to regulate construction of new and existing commercial buildings, according to an ICC press release.

The IGCC aims to significantly reduce energy usage and greenhouse gasses. It addresses site development and land use, including preservation of natural and material resources. Enforcement of the code will improve indoor air quality and support the use of energy-efficient appliances, renewable energy systems, water resource conservation, rainwater collection and distribution systems, and the recovery of used water (graywater).

The IGCC emphasizes building performance, including features such as a requirement for building system performance verification and building owner education to ensure the best energy-efficient practices. A key feature of the new code is a section devoted to “jurisdictional electives” that will allow customization of the code beyond its baseline provisions to address local priorities and conditions.
