Our Somerville Nstar DER (deep energy retrofit) has the finish line in sight. The exterior is in punch list mode and is looking good.
As the series of photos below prove, there is no compromise on the aesthetics of a DER. No one (other than the people who executed the project and the people who are saving money on their energy bills) can tell that there is an additional 4″ of foam on the sidewalls and roof surfaces.
The interior is being painted on the first floor and trim being finished in the attic. The basement has been foamed and the Buderus wall hung boiler is up and running. We re-used the Ultra Super Store water tank, but all other mechanicals are new.
