An updated statewide energy code for new homes and commercial buildings in Maine takes effect July 1, adding to the state’s effort to fight climate change in a sector responsible for nearly one-third of greenhouse gas emissions. The new rules will lead to tighter buildings that waste less energy. And while added insulation and air-sealing procedures will increase the cost of new construction, officials say they will create a net savings on utility bills and more comfortable living spaces.
