A Home Retrofit for #1 Dartmouth
“I paid off my house last year,” Ted Cashin explains, “and thought now that I have some spare money, I’ll invest some back in my house.”
So Ted called in Retrofit America. We started with a complete home energy audit for Ted’s home in Avondale Estates.
“It’s a good opportunity to look at how the whole house works,” Ted says. “You analyze the whole house. You’re not just looking at one piece. You’re looking at the whole system – how to make it all work together.”
Retrofit America improved the insulation in Ted’s attic, and he installed a new HVAC system.
For his attic space, Ted had two options: Adding more blown fiberglass insulation to the attic plane or spray foaming under the roof deck and gable walls.
“I don’t really need the attic for storage, and I don’t have HVAC equipment up there,”he says. “so improving the blown insulation is much cheaper.”
To get Ted’s attic right, first sealing air leakage is key. We covered the whole-house fan with a foam board box and installed an attic insulation tent. Then we blew another 10″ of fiberglass insulation to bring the insulation value to R-38.
What was the impact?
“The next day I left my home at noon and moved my thermostat setting up from 75º to 79º,” Ted says. “It was in the 80s all afternoon. When I got back home that evening, the temperature in my home was only 77º. My home had stayed cool on its own. What great efficiency!”
