Heat Loss Calculator
Calculate heat loss for your building based on insulation, materials, and climate. Understand how to reduce energy costs and improve thermal efficiency.
Step 1: Building Details
Understanding Heat Loss
Heat loss occurs through walls, roofs, windows, and air infiltration. Better insulation and airtightness significantly reduce energy consumption and heating costs.
Step 2: Climate & Cost Details
About Heating Degree Days
Heating Degree Days (HDD) measure how cold your climate is over a heating season. Higher HDD values mean more heating is required, increasing energy costs.

Heat Loss Breakdown
Heat Loss Formula
Q = U × A × ΔT + Infiltration Loss
Total heat loss (Q) is calculated by summing conductive losses through building surfaces (U-value × Area × Temperature difference) and adding infiltration losses from air leaks.
