The calculation is an estimate based on window area, solar exposure, solar factor (g-value), cooling demand and an assumed electricity price. Actual savings vary according to orientation, shading, property design, air-conditioning efficiency and usage.

The calculator assumes an average window size of 2.5 m², a warm Canary Islands climate at ocean level with significant cooling demand and an estimated electricity price of €0.20 per kWh. The calculation assumes an expected window lifespan of 30 years. Solar-control performance is based on the stated g-values for each NORTH™ glazing option.
