I finally had a meeting with Paul Eldrenkamp of Byggmeister, a green / sustainable contractor. The conversation went well. We talked about what we may do to accomplish a high performance retrofit on the Hudson house and the need for an addition on the north end to provide a additional workspace
(woodworking) as my Dad left me with a basement full of machine tools which I will continue to appreciate.
Part of the retrofit will be increasing the insulation value of the walls ( foundation and box ) and roof to a minimum of R-40 and R-60.
This will be accomplished by adding 10" of cellulose to the EXTERIOR of the box walls and possibly 26" to the roof.
The house will be completely air sealed and will incorporate an active "energy recovery" ventilation system.
I'll be adding photos to a new page here which will be titled #9 - - - - -
