One of the toughest challenges for the building industry is devising pathways for deep energy retrofits that are both economical and feasible. This is even more challenging in co-ops, as these buildings are managed by a board of members who vote on rules, policies and changes to them. 

On May 17, the third event in our Energy Upgrades in Historic Buildings series will look at a 10-unit co-op built in 1926 and the challenges of upgrading the envelope and converting the fossil fuel boiler to a heat pump.
