If energy consumption is low, there is a lower savings potential

Fig. 2 Estimated average apartment electricity consumption.



Fig. 2 above shows the average consumption of electricity relative to apartment size in square meters. The legend on the right identifies the number of people in the apartment. The curves in figure 2 are based on the following formula (Gram-Hanssen 2005):

Annual consumption = 340 kWh + (area in square meters * 11 kWh/square meters) + (no. of persons * 350 kWh/person)

Example: area in square meters = 100, no. of persons = 2

Annual electricity consumption (kWh) = 340 + (100 * 11) + (2 * 350) 
                      = 340 + 1100 + 700 
                      = 2140


In some cases the formula may be easier to use than the graph. All values are approximations based on average readings.
