Building Codes

Building codes are a foundational policy that ensures energy efficiency is integrated into all new buildings statewide. If energy efficiency is not incorporated at the time of construction, the new building stock represents a “lost opportunity” for energy savings because it is difficult and expensive to install efficient measures and equipment after construction is completed. Mandatory building energy codes are one way to target energy efficiency by requiring a minimum level of energy efficiency for all new residential and commercial buildings in a state. Enforcing compliance with building codes can be difficult and costly, but a concerted effort to fund and train code officials has the potential to generate significant energy savings for a state, helping consumers to save money on their energy bills and thereby making businesses more viable and homes more affordable.
