City of San Antonio - Residential and Commercial Green Building Requirements

In 2009, the mayor of San Antonio announced the “Mission Verde” plan, which included several energy savings goals. As part of this plan, the City Council enacted an ordinance in March 2009 requiring all new buildings in San Antonio to meet a 15% greater efficiency rate than what was required in the 2008 city energy code and establishing goals of 30% energy saving by 2012 and net-zero carbon emissions by 2030.

In December 2011, the City Council adopted the 2009 International Energy Conservation Code, Chapters 2 through 5. 

In October 2018, the City Council adopted the 2018 International Energy Conservation Code.
