Strategies for Decent Energy Retrofit Payback Period
Looking to upgrade a 1 story ranch built in 1950 with a full basement in climate zone 4A (ny metro area). I’ve listed the details below. I’m looking for ideas with a decent time of payback rather than full on deep energy retrofit.
– Frame house with brick veneer all around. Veneer appears to be in good shape
– Traditional vented room with gable ends with a fan for powered ventilation. I plan to disconnect the fan, seal the attic, and increase insulation to R60.
– Gas powered hydronic radiators for heat
– Through the wall AC units / no ducting in the house. I will get rid of these, close the holes, and install mini splits
– Chimney brick fireplace: I do not plan to use this, but not sure if taking it out would be worth it
– Windows are mixed between wooden single pane and dual pane windows throughout the house. I probably will replace them all as I have a lead paint concern.
– I don’t know what type of sheathing is in the house
– Plaster walls on main floor, probably original with no insulation
– Basement was finished in the 2000s with drywall. I will need to find a way to insulate the rim joists.
I want to add insulation in the walls, but I’m not sure how to go about it. I thought of two ways to go about this.
1 – As this house was built in 1950 and may have lead issues (waiting on inspector), I considered just taking down the plaster walls and replacing it. This would give me a chance to insulate, maybe add a smart vapor barrier, and update the electrical if needed, but I’m not sure if it’s cost effective.
2 – Use a service that fills the wall cavities without demolition.
Any suggestions are welcomed. Thank you all for taking the time to read my question.
