A little more than 4 out of every 5 buildings that will exist in the Commonwealth in 2050 have already been built. 65% of the current total built square footage was built before 1980 and 39% of all residential building square footage was built prior to 1950.

This discussion will focus on the need for more data around building envelopes and how this data can be utilized for deep energy retrofits.
