3.1 Building description 52 The main goal of this part of the dissertation is to determine the thermal performance of the analyzed dwelling house. The current simulation is divided into five sections and is described in the following sequence: • determination of the thermal performance of the building, • determination and comparison of the gain and loss of thermal energy through building fenestration, • determination of the thermal environment in the apartments during the warm period, • modelling of a domestic solar water heating system, which has the following components: tube collectors, storage tanks and auxiliary water heater. 3.1 Building description The analyzed five-storey house consists of nineteen apartments, a staircase and a storeroom. The building envelope is designed for the optimal utilization of solar radiation energy during the heating season. 3.1.1 Description of building substructures and HVAC systems External walls The external walls are designed as a three-layer structure. A load-bearing wall is constructed of ceramic hollow-bricks POROTON Block-T 24,0-1,2 (Fig. 3.3). A new kind of building material POROTON-T9 (Fig. 3.4) is used to make the curtain walls. The traditional hollows are filled with a thermal insulation material called perlite. Thanks to this procedure a very low value of thermal conductivity is obtained. Fig. 3.3: POROTON Block-T 24,0-1,2.

The results of the three temperature differences between the brick sides are summarized in Table 3.2.
