This map layer shows the modeled heat demand (in gigajoules per year) per building. The map contains all buildings in Overijssel from the Key Register of Addresses and Buildings (BAG) of June 2019. Based on the surface area of the building, the energy labels (for homes), the function (for utilities) and key figures, a heat demand per address has been calculated. The heat demand per address is listed, resulting in a heat demand per building. The heat demand for building heating, tap water and greenhouse horticulture is included, but not for industrial processes. This is because this is typically a heat demand at a (much) higher temperature level. The key figures used come from the research: Greenvis (2018) 'Exploration of heat network Eemsdelta - Groningen' and 'IF Technology, CE Delft, Berenschot (2018) 'Scaling up geothermal heat in heat networks - An analysis of the added value of the play-based portfolio approach' . These key figures indicate the heat demand per square meter per energy label or building function. The results based on these key figures have been compared with the actual energy consumption in neighborhoods of the municipality of Zwolle in 2014. This shows that this gives a good indication (average deviation 5%). This approach gives accurate results, especially for neighborhoods with many homes (standard deviation 0.16). In neighborhoods with many companies, the standard deviation is higher because of a larger variance in the actual energy use per company.
