Average Energy Savings by Area
| Insulated Area | Potential Energy Savings | Payback Period |
|---|---|---|
| Attic | 15–25% | 1–3 years |
| Crawl Space | 10–20% | 2–4 years |
| Basement | 10–15% | 3–5 years |
| Whole Home | Up to 30% | 2–5 years |
These savings increase when insulation upgrades are combined with air sealing and efficient HVAC systems.
