- Abstract
Impact of the heat storage capacity on heating demand and thermal comfort. Dynamic simulations for a single-family house and a multi-family house are used to demonstrate the impact of the heat storage capacity from external and internal constructions on the heating demand and the thermal comfort during summer periods. For a heavy (calcium silicate masonry) and a lightweight situation (wood) typical constructions for walls, ceilings and floors are investigated and the calculations distinguish between with and without nighttime temperature reduction. The following three different levels of thermal insulation of the buildings envelopes are taken into account: 'EnEV 2016', 'KfW Efficient House 55' and 'KfW Efficient House 40'. As far as possible, the calculations are based on the criteria and boundary conditions of DIN V 4108-6, DIN V 18599-10 and DIN 4108-2. As climate file the actual TRY-data for Potsdam (TRY04) is used. It is shown that the heavy constructions provide certain advantages both concerning the heating demand as well as especially regarding the thermal comfort in summer periods. Depending on the buildings geometry, the insulation level and the boundary conditions (nighttime temperature reduction) the heating demand savings compared to the lightweight situation reaches up to 4 %. Regarding the thermal comfort in summer periods, it is quiet easy for the heavy situation to ensure summer heat protection and minimum requirements without active cooling.
