Maryland adopts International Green Building Code

In 2009, the International Code Council launched the development of a new International Green Construction Code (IgCC) initiative, subtitled “Safe and Sustainable: By the Book,” committed to developing a model code focused on new and existing commercial buildings addressing green building design and performance.

Maryland will be the first state to adopt this new green building code in 2012.

The International Green Construction Code (IgCC) acts in conjunction with other existing codes, such as the International Energy Conservation Code (IECC).

Features of the new code include:

-a Zero Energy Performance Index (zEPI), which requires buildings to use no more than 51% of the energy allowed in the 2000 IECC.

-a 20% water savings beyond US federal standards for residential water closets.

-the addition of appliance information, radon mitigation, and commissioning documentation to ensure the health and safety of building occupants

-land use regulations that address flood risk, greenfields preservation, use of turf grass, and minimum landfill diversion requirements

The IgCC is sponsored by the AIA, ASHRAE, USGBC, and IES. It includes the ANSI/ASHRAE/USGBC/IES Standard 189.1 (the successor to ASHRAE 90.1-2007) as a jurisdictional requirement option.

The public comment period ends 12 August 2011, and final action will take place on 6 Nov 2011. The IgCC will be fully integrated into the existing International Code Council (ICC) code family in early 2012. It will take effect in Maryland on 1 March 2012; adoption will be voluntary.

I'm wondering why do we need an international code for green building? What are the importance of international code?
