Introduction S1: Following the European directive on the energy performance of buildings (EPBD), all the member states of the European Union (EU) should enact national plans and objectives to improve the use of the buildings, which consume very low and close to zero energy. S2: For the last few years, the building aspect is responsible for nearly 40% of the global energy demanded in the EU. S3: A a case in point is the fact that the application of the Heating, Ventilation and Air Conditioning (HVAC) systems is considered a essential fraction of the energy consumed in building sector. S4: Hence, the reduction of the energy waste of the building is attracting widespread interest in recent years. S5: One of the most effective solutions to …show more content…

Furthermore, during summertime, Di Perna et al. studied the influence of the thermal mass location in the envelope of the building with high internal loads. The results presented that the thermal mass should be placed on the internal side of the building envelope. S7: Nevertheless, the most critical parameters such as heat gains, schedule, and ventilation in previous study were ambiguous. Consequently, there remains an urgent need for a detailed experiment to evaluate the impact of internal heat loads in the overall thermal performance of the building. S8: This study aims to analyze the thermal influence of the internal heat loads when insulation and PCM are located in the external building walls. S9: Based on the previous experience obtained from the experimental set-up of Puigverd de Lleida, a similar methodology was conducted during the summer period. S10: Thermal loads are supposed to be absorbed, for PCM in the building envelope rises the thermal energy storage capacity. What’s more, the polyurethane insulation reduces the heat from the external conditions, whereas the internal heat loads cannot be dissipated easily. Methodology S1: This experiment was conducted in the experimental facility of Puigverd de Lleida, Spain. S2: The climate of this area is dry and hot summer, which is also called Csa according to the Köppen-Geiger climate classification system. S3: The
