This work in the part related to the development of data acquisition and heating/cooling systems was supported by the NCBiR (Poland) under M-ERA.NET 3 grant no. M-ERA.NET3/2022/72/Wood-wastePanels/2023 " Wood waste containing composites for high performance nearly zero energy building panels, Wood-wastePanels".
This paper presents the development of an experimental test house for real-world measurements of heat transfer in a building composite of hemp shive and magnesium binder with microencapsulated phase change material (PCM) to increase the thermal mass of the building material and improve internal thermal comfort. The test house was developed as a small building erected from prefabricated three-layer blocks with dimensions of 600×400×240 mm3 (length × width × height). The outer layers of the blocks had a density of approximately 400-450 kg/m3 and a thickness of 50 mm (without PCM) and 60 mm (with PCM), while the inner layer had a density of approximately 200-250 kg/m3 and a thickness of 290 mm. The building had dimensions of 2.60×3.10 m2 and a height of 3.36 m, with walls facing in the cardinal directions. A door was placed in the north wall. The east and south walls had a layer of PCM facing outwards, while the west wall faced inwards. The temperature inside the building was stabilized at 20°C using a specially designed heating/cooling system. Six temperature and relative humidity sensors (HDC 1080) were placed inside the two blocks in each wall, except the north wall. In addition, heat flux sensors were mounted under the internal plaster on the east and south walls. Indoor and outdoor air parameters, solar radiation, and wind speed were also monitored. In addition to the description of the test house, exemplary data for two measurements over a period of one week in two different months are discussed.
