Passive House Heating Demand

Construction

Estimate passive house heating demand. Formula: Heat Loss (kWh/m²) = U-value × ΔT × hours / 1000. Reference for energy standard.

Formula

Heat Loss = U-value × Area × ΔT × hours

U=0.15, 150m², 25K

Inputs
  • U-Value (W/m²K): 0.15
  • Area (m²): 150
  • Temperature Difference (K): 25

~15.5 kWh/m² annually
