Calls are mounting for a Senate floor vote on the Energy Savings and Industrial Competitiveness Act of 2011 (generally referred to as the Shaheen-Portman bill). The bill introduces a variety of measures that encourage or facilitate energy efficiency in residential and commercial buildings. These include a section that strengthens the Department of Energy’s authority to require that national model energy codes attain deep energy savings. Before becoming law, these model codes must be adopted at the state (or sometimes local) level; most states do adopt them.
Do these codes work? Do they help households and businesses save money and energy? Evidence shows that they do.
