Architects and builders continue to innovate with structural insulated panels (SIPs), proving the benefits of affordable, healthier, and more resilient homes.

Economists often say that markets make the best decisions. But that can be true only when markets have accurate and complete information. Today, the housing market is flying blind regarding one of the most important characteristics of a home: energy use. The solution is mandatory energy disclosure at the time of sale. It’s good for buyers, sellers and the climate.

Leading U.S. cities are filling a crucial information gap in the residential real estate market by requiring home energy disclosures for potential homebuyers: a much needed transparency measure and consumer protection practice. This process provides buyers with an energy efficiency rating on every property listed for sale. An online resource and a support network are available for local governments that want to adopt similar energy disclosure measures.

The US government may be moving backward on climate action, but cities and other local governments are forging ahead. Zero Energy Project has assembled a list of more than 400 cities and their climate action plans from around the US and Canada.
