The formula for the energy consumption of the building [(kW·h)/year] is:<br />
Σ (A·U) · coefficient /1000<br />
Having all the U-values and areas calculated, they must be multiplied (A · U):<br />

Σ(A·U)= 237’192+149’492+680’506+123’24+14’472=1204’902 W/°C<br />
The coefficient depends on the place where the building is situated and the<br />
adequate temperature to be comfortable inside the building.<br />

The nearest city to Halmstad, and therefore, the city in which temperatures are<br />
most similar, is Malmo, and a good indoors temperature is 22 ºC, so the<br />
coefficient is 95800.<br />
