According to this method, the district heat consumption for the entire development block in the example shown in Figure 11 results as 23.3 kWh/(m²a) in a first approximation. The base consumption is 3.72 kWh/(m² month) x 12 months = 44.6 kWh/ | According to this method, the district heat consumption for the entire development block in the example shown in Figure 11 results as 23.3 kWh/(m²a) in a first approximation.

This type of calculation basically allows the calculation of the heating consumption value from the little measured data that is available. However, for different reasons, this first approximation leads to **overestimation of the heating consumption**: | This type of calculation basically allows the calculation of the heating consumption value from the little measured data that is available.

In winter the ambient temperatures are lower and therefore heat dissipation from heat distribution pipes increases. Through calculation of the "base heat" from the summer values, the increased dissipated heat in winter is completely attributed to the heating consumption. Estimation of the scale was performed for one of the development blocks. In doing so, a distinction was made between pipe lengths in the ground and in the basement, and the linear thermal transmittances of the different pipes were taken into account. The result is a difference of 1800 kWh/a between the summer approach and taking into account of the lower temperatures in winter, corresponding with about **2 kWh/ |
