Updated Building Energy Codes

Local Market
Energy Efficiency

Opportunity: States with updated building energy codes can better leverage rapid innovations in energy efficiency products and processes that can provide greater energy and cost savings for building owners and residents. For states with robust energy efficiency clusters, updated codes also create a stronger market for local energy efficiency products.

Solution: States and municipalities could adopt the most current residential and commercial energy codes based on the International Energy Conservation Code (IECC) and ASHRAE 90.1. IECC and ASHRAE 90.1 serve as national model energy codes and are updated every three years to best reflect cost-effective, energy-efficient upgrades for building design and construction. Policymakers could also complement code adoption with a strong compliance plan to ensure maximum energy and cost savings across the building stock.

Example: A resident’s life-cycle cost savings under the 2015 IECC are estimated to be between $119 and $438 more than the 2012 IECC and between $4,418 and $24,003 more than the 2009 IECC. ASHRAE 90.1-2013 provided an average of 8% in reduced on-site energy use compared to the 2010 code and 26% compared to the 2007 code.
