Starting January 1, 2013, the State of Illinois will be adopting the International Energy Conservation Code (IECC 2012). The IECC addresses energy efficiency, focusing on cost savings, reduced energy usage, and the impact of energy on the environment. This code acts as the basis for minimum energy requirements for new building construction.
IECC 2012 is the sixth edition of the code. This edition will improve thermal envelopes, HVAC systems, and electrical systems. Some of the changes include:
- HVAC Commissioning will be mandatory for commercial spaces of approximately 17,000 sf or greater. Requirements include a commissioning plan, systems adjusting and balancing, performance testing, and documentation.
- Tighter building envelopes will be enforced with a maximum percentage of windows to gross wall area of 30%.
- Free cooling economizers will be required in HVAC systems and equipment, dependent on climate zone.
- Energy efficient lighting will require 0.9 w/sf in office environments.
