Share 'Estimating E savings from air sealing in huge leaky house'
I'm asked to estimate the heating energy savings from air sealing a 10,000 sf house built in 1900. The former mansion has 6 undampered chimneys and about 40 windows needing repair as well as doors, some needing replacement and all needing weatherstripping. The house has a semi heated basement, and three stories on top of it.
The house has new radiators in all rooms and a 92% efficient boiler.
