Adaptation of a stochastic simulation model for long-term investigation of the development of the energy demand in larger building stocks

In order to design the energy transition process, strategies to gain high energy saving potentials are needed. To assess the primary energy demand of a building stock of about 3,5 million buildings a model originally used for calculating the heat demand of rural districts was adapted. To close the gaps in the statistical data many assumptions had to be made. The impact of the assumptions had to be summarized as well as several supplements which indicate the technical components had to be implemented.
