Window U-Value Heat Loss Calculator

Calculate heat loss through windows based on U-value (W/m²K), window area, and inside/outside temperature difference. Compare single, double, and triple glazing

Each component has a specific meaning:

• U-value — The u-value recorded for the patient or scenario being assessed.
• Window area — The window area recorded for the patient or scenario being assessed.
• Inside/outside temperature difference — The inside/outside temperature difference recorded for the patient or scenario being assessed.

Note: Interpret the window heat loss result against the clinical thresholds and context described above.

Enter the U-value, window area, inside/outside temperature difference for the patient or scenario you are assessing. Calculate heat loss through windows based on U-value (W/m²K), window area, and inside/outside temperature difference. Compare single, double, and triple glazing. Use the window heat loss result to inform your clinical assessment.
