Spatial heat demand model (historical 2022) NRW

This dataset has been replaced by the data set “Data municipal heat planning”. The data will continue to be offered as “historical” data. The spatial heat demand was determined for the first time in the course of the potential study Renewable Energies NRW Part 4 – Geothermal energy. This is a model-based demand calculated under conservative assumptions. On average, it tends to be higher than actual heat consumption. The data are available at building level and per road section (heat lines). The heating requirements of the residential buildings were determined on the basis of the building floor area and height. In addition, assumptions about the year of construction of the buildings were made from data from the census and taken into account in a recalculation in 2016. By revising in 2020, the model has been significantly improved. In addition to the room heat demand, the demand for hot water also flows into the model at a flat rate of 15 kWh per square meter. The spatial heat demand of non-residential buildings was determined on the basis of the building usage, height and floor area. Process heat requirements were not taken into account here. The classification of residential and non-residential buildings may lead to confusion due to mixed uses. The data set is based on the ALKIS building stock as of 03/2019. The attributes are explained in more detail in the respective documentation (Hausumringe.pdf/Waermelinieden.pdf). The data set will be updated if necessary, without a specific turn.
