Starting July 1, Maine officially upgraded from the 2009 to the 2015 International Energy Conservation Code. Although still behind code versions, there are some important upgrades for our new homes. Of course, this is a minimum code and all of DMA designs exceed the energy code. Now at least the houses not designed by architects will have improved energy efficiency in our state.
