Figure 57. Calculated annual consumption of lighting and electrical devices in the flats (3 years data). Blue = normal annual
electricity demand in DK ­ app. 2000 kWh/y, Red = Average demand of the 56 flats ­ app. 1906 kWh/y.
Figure 58. Calculated annual consumption of lighting and electrical devices in the flats (last year data). Blue = normal annual
electricity demand in DK ­ app. 2000 kWh/y, Red = Average demand of the 64 flats ­ app. 1933 kWh/y.
The differences between 3 years and 1 year data frequency distribution can be seen in Figure 59: with a
higher number of flats (1 year data) there is an increase in the frequency peak consumption class (1500
kWh/y) which is common to both datasets. This, together with the decrease of the 2000 kWh/y class should
lead to a lower average value, but this positive effect is balanced by the increase of the 3000 kWh/y class.
