Vermont’s Comprehensive Energy Plan…60% of all new homes in Vermont to ENERGY STAR standards or Efficiency Vermont’s Energy Code Plus and broader market penetration of net-zero energy buildings, with a goal of having 30% built to net-zero design standards by 2020 as an interim target on the way to 100% net-zero buildings by 2030. In Vermont this translates to approximately 275 single family homes built to HPH standards per year.
