**Average apartment heating consumption**

*Low heat consumption means less potential for savings*

Fig. 2 Estimated average apartment consumption. |

The graph in the above figure is based on the following formula (Gram-Hanssen 2005):

Annual heating consumption = -2 577 kWH + (area in square meters * 119 kWH/square meter)

Example: apartment area in sqm = 100 Annual heating consumption (kWH) = -2 577 + (100 * 119) = -2 577 + 11 900 = 9 323

In some cases it can be easier to use the formula instead of reading the graph. The results are only approximations, as the formula is based on the median of numerous calculations.
