Commercial Energy Code - Effective September 2, 2011
On August 3, 2011 Houston City Council voted to approve adoption of the new Houston Commercial Energy Conservation Code. This code adoption is in response to the State Energy Conservation Office requirement for Texas municipalities to update their minimum codes to the 2009 International Energy Conservation Code (2009 IECC). Local amendments will allow projects to demonstrate compliance with either the 2009 IECC or the ASHRAE 90.1-2007 standard.
The amendments were prepared for each code to provide comparable provisions for both options. Adoption of these two codes will allow the designer to choose the code that works best for the project while maintaining a high level of energy efficiency.
