Effective January 1, 2012: 2009 International Energy
Code with Amendments
What is the International Energy Code (IECC)?
- The IECC establishes a baseline for energy efficiency by setting
performance standards for the building envelope (defined as the
boundary that separates heated/cooled air from unconditioned,
outside air), mechanical systems, lighting systems and service
water heating systems in homes and commercial businesses.
- The IECC does NOT regulate the efficiency of equipment, like
computers or coffee pots or the efficiency of industrial
processing, such as equipment for manufacturing.
- The IECC does NOT regulate renewable energy systems such as
solar thermal water heaters or solar photovoltaic panels.
The IECC focuses on the energy efficiency of building systems
All new home and commercial construction, remodels
and additions will need to follow the IECC standards
starting January 1, 2012.
