The new International Green Construction Code is aimed to increase energy efficiency of structures providing government's direction and comprehensive direction of green design guidelines. The 2012 IGCC incorporates ASHREA 189.1 (an important new energy standard) as a compliance path and sets the goal to improve energy efficiency by 30%. The International Green Construction Code presents specific design details on how to assemble building components to achieve higher efficiency.
The IGCC offers a new code that could be customized by local governments to adopt specific provision for sustainable buildings whether or not they are part of the LEED program. The 2012 version of the IGCC is being endorsed by the American Institute of Architects (AIA), ASTM international (ASTM), ASHRAE, the Illuminating Engineering Society (IES), and USGBC.
The code presets special emphasis on grey water, ventilation systems, and present details on how to improve a buildings thermal envelope. Some LEED buildings have missed their energy goals, and a big reason is because neither LEED nor code looked closely at wall assemblies, windows, and doors.
