Thermal flow simulation for an energy garden building block

Since energy-efficient construction is of great importance, new construction and rehabilitation methods concerning this topic will always be researched. Among these are of course, methods that benefit from solar energy. As part of the BMWi project (Federal Ministry of Economics and Energy) “SWIVT” several options of the energy consumption of residential building blocks will be explored. One of approaches to reduce the energy consumption of the building block and additionally to achieve the energy gain through the solar radiation is an energy garden building block (glass porch). The impact of this energy garden is depicted by means of CFD-simulations (Computational Fluid Dynamics) and will be analyzed in the paper [1]. For this purpose, an energy garden was modeled using an architect drawing and simulated in both winter and summer load cases. For the winter case, the difference in energy consumption between the glass porch and the thermal insulation composite system (ETICS) will be discussed based on the results of the simulation. For the summer, the heat generated by solar radiation in the energy garden can be utilized with the help of a heat pump.
