The Home Energy Audit Savings Calculator estimates how much you can save annually by identifying and fixing common energy inefficiencies in your home, including air sealing, insulation, HVAC upgrades, and appliance replacements.
ସୂତ୍ର
Total Savings = Sum of (Current Usage - Efficient Usage) x Energy Rate for each improvement category
- Ec
- Current Annual Energy Cost ($/year) — Total annual electricity and gas bills
- Sp
- Savings Percentage (%) — Expected reduction from each improvement category
- Ci
- Implementation Cost ($) — Cost to implement the energy efficiency improvement
- PB
- Payback Period (years) — Time to recoup implementation cost through energy savings

ସମାଧାନ ହୋଇଥିବା ଉଦାହରଣ
ଇନପୁଟ୍
$2,400/yr electricity, $1,200/yr gas; improvements: air sealing + attic insulation + LED lighting
ଫଳ
Air sealing saves $360/yr, insulation saves $240/yr, LEDs save $180/yr. Total: $780/yr savings (22% reduction)
ଇନପୁଟ୍
$3,600/yr total energy; full audit improvements including HVAC upgrade
ଫଳ
Total savings: $1,260/yr (35% reduction). Investment: $8,500. Payback: 6.7 years.
ଏଡ଼ାଇବା ଯୋଗ୍ୟ ସାଧାରଣ ଭୁଲ
- ✕Skipping air sealing before adding insulation — air leaks can account for 25-40% of heating/cooling loss
- ✕Replacing windows for energy savings alone — windows have 15-30 year payback vs 2-5 years for insulation and air sealing
- ✕Not considering that the IRA provides up to $1,200/year in energy efficiency tax credits for qualifying improvements
