6 Diane Boulevard, Fallsburgh, NY

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.

Split-level homes divide living space across multiple partial floors, which can complicate air sealing because there are more floor-to-floor transitions and more exposed rim joist area. They also tend to have garage spaces that share walls with living areas, another common heat loss pathway.

Based on confirmed building data, EcoAudit estimates annual energy costs for this home at $2,300 to $3,850, assuming natural gas heating and typical usage patterns for Central New York. A targeted set of improvements - usually starting with attic insulation, air sealing, and possibly equipment upgrades - could reduce that by $750 to $1,750 per year. New York State and National Grid offer rebates that cover a meaningful share of weatherization costs for homeowners in Onondaga County.
