Energy & building physics

Thermal performance, heat loss, moisture, solar PV and battery planning.

Calculate total thermal resistance and U-value for a layered building element.

Estimate insulation thickness needed to reach a target U-value after accounting for other thermal resistances.

Estimate transmission and ventilation heat loss from envelope area, U-value, air changes and temperature difference.

Calculate dew point from air temperature and relative humidity and compare it with a surface temperature.

Estimate daily, monthly and annual PV energy from installed kWp, peak sun hours and performance ratio.

Estimate usable stored energy and backup runtime from battery capacity, depth of discharge, efficiency and load.
