After some questioning on the impact to condo owners, the Committee on Health and Environmental Protection unanimously approved amendments to the city’s building code to require new and rehabbed structures be more energy efficient. Buildings Commissioner Judith Frydland says the changes would standardize energy code provisions statewide and locally, cut down on confusion for contractors, and boost energy savings by up to twenty percent above the current code requirements. Frydland also hinted more code changes are coming after this year’s budget season.
