The 1970s brought the first real energy codes to New York State, which means a home from this era is likely better insulated than its older neighbors - but "better than 1965" is a low bar. Homes from this period typically have R-11 wall insulation and varying attic levels depending on when they were built and whether improvements have been made since. They're also the era of the first wave of replacement windows, many of which are now 30-plus years old and performing well below their original specifications.

EcoAudit's estimate for this property is based on the typical housing stock in Peru and Onondaga County's climate zone 6A rather than confirmed building data. The actual energy profile depends heavily on what's inside the walls and attic - factors that only a walkthrough assessment can confirm. New York State and National Grid offer rebates that cover a meaningful share of weatherization costs for homeowners in Onondaga County. A free EcoAudit assessment identifies exactly where this home is losing energy and which programs apply.
