Triple deckers are one of the most dominant, widely recognized, and iconic residential building types in Massachusetts. Tens of thousands of triple deckers were built during the late 19th and 20th centuries across New England to serve as an economical means of housing to thousands of newly arrived factory immigrant workers. They are typically three-story, wood, balloon-framed structures that consist of three apartments with generally identical floor plans, exterior porches, and a mix of flat and gable roofs.

As the Commonwealth strives to meet its 2050 net-zero emissions goal, it is necessary to retrofit triple deckers to assist in emissions reduction. MassCEC’s Triple Decker Design Challenge resulted in 13 proposals for all-electric energy retrofits of these buildings. MassCEC is “getting out the vote” for the $10,000 People’s Choice Award, which is determined by a popular vote cast at this link.

We are pleased to announce the event will open with a guest appearance from Kevin O'Connor of This Old House.
