Paano Kalkulahin si Insulation Savings

Ano ang Insulation Savings?

Home insulation reduces heat loss through walls, loft, and floor. Higher R-value = better insulation. Loft insulation typically offers the fastest payback — often under 2 years.

Pormula

R-value total = Sum of layer R-values | Heat loss = Area × ΔT / R-value | Annual cost = Daily cost × 365

Step-by-Step na Gabay

1Heat loss ∝ Area × U-value × ΔT (U = 1/R)
2Doubling R-value halves heat loss through that element
3Payback = Install cost / Annual energy saving
