Abstract: Building energy flexibility may support higher penetration of renewable energy sources into electrical grids in the near future. In this work, thermal inertia of a family house is evaluated using building energy simulation tools. The simulation study is based on the interior temperature response to a sudden shutdown of the heating source while considering theoretical boundary conditions (i.e. constant exterior conditions). This experiment is intended to assess the energy flexibility potential of both building and its heating system. In addition, this simulation analysis elaborates the sensitivity of the interior temperature response to the model parameters such as the storage tank volume, the thickness of insulation and inner wall layers. The results of this study help to understand the thermal capacity of buildings including their heating systems.
