“…In this context, the building envelope plays an important role in meeting the challenge of energy transition. Indeed, a good design of the envelope effectively contributes to reducing energy consumption, as concluded by several research studies [8,9]. The improvement of energy performance as well as the thermal state of the building depend not only on the satisfaction of the occupants but also on the properties of the envelope (opaque and translucent) as well as the external climatic conditions [10,11].…”

In the early stages of building design, decisions are made about the building’s form and envelope, but designers rarely base their decisions on sophisticated energy simulations, even though these features are critical to a building’s energy performance. This paper employs three methods—empirical, parametric, and uncertainty—to assess the interconnectedness of building form, envelope, orientation, and occupancy regarding thermal comfort and energy consumption for heating and cooling a residential building across three regions: Gdyel (mediterranean climate), Oum El Bouaghi, and Constantine (semi-arid climate). The study variables include indoor air temperature, relative humidity, and energy consumption. The initial findings stem from an experiment conducted in an apartment on the top floor of a building in Gdyel, which allowed us to record the evolution of the variables mentioned throughout the year and validate the parametric results of the multi-zone model created in TRNSYS16 software. This study showed that for the considered climates, a compact form is more suitable; it was found that the top floor with SF = 0.57 needs about 30% to 54% more energy than the inter-floor with SF = 0.21. In addition, the heating and cooling methods and habits adopted by Algerian households are responsible for 18% to 35% on the top floor and the inter-floor, respectively.

“…Numerous approaches exist for incorporating PCM into the structural design of buildings, ,, and several techniques have been utilized to enhance the heat transfer performance of PCM composites. These approaches involve integrating PCMs into porous materials with high thermal conductivity, such as graphite or metal matrices, dispersing highly conductive particles within the PCM, using multiple PCMs, and employing microencapsulation of PCMs. , Depending on how shape-stabilized composites are integrated into buildings, there may be a need to safeguard them from potential damage caused by interactions with surrounding materials, additional thermal stresses, and vapor pressures resulting from volume changes during phase transitions .…”

This study aims to explore the effects of augmenting the mass proportion of a composite comprising paraffin and beeswax (PBPCM) within plaster, which influences the thermal insulation of a dual wall. This work is primarily based on the thermal properties of the composite material PBPCM/plaster with varying percentages of PBPCM. Various essential parameters, such as density, thermal conductivity, specific heat capacity, thermal diffusivity, and latent heat, were assessed and juxtaposed with those of conventional plaster for the PBPCM/plaster composite material. The evaluation of this composite material was executed through an experimental device on a laboratory scale. The obtained results show that the increase in the mass fraction of PBPCM in the plaster decreased the thermal conductivity of plaster more than 3 times, whereas this increase of the PBPCM fraction in plaster enhances heat retention, specifically in specific heat capacity under constant conditions. Nevertheless, in a dynamic state, thermal effusivity has the lowest value for 50% PBPCM. The recommendation is to utilize 50% PBPCM, as it yields an optimal thermal effusivity, and significant values of specific heat capacity and latent heat have been noted for this percentage of PBPCM, measuring 1263.77 kJ/kg K and 18.9 kJ, respectively. Additionally, an increase in the PBPCM percentage narrows the temperature range suitable for effective thermal energy storage.

“…With an excess of heat, accumulation (accumulation) occurs, with a shortage, return. For the effective accumulation of heat/cold, provided that the internal air temperature is maintained within the normalized values, enclosing structures have been proposed, which include substances with a phase transition [4][5][6][7][8][9][10][11][12][13]. In the case of intermittent operation of heating (cooling) systems, the heat storage capacity is directly taken into account to improve the accuracy of calculations [11][12].…”

The method of calculating the cooling rate of a room when the heating system is turned off there is an important practical task. As a result of such calculation, the time within which the room will cool down to an acceptable temperature, is indicated. During this time, emergency brigades must restore heating in the building. The aim of the work is to provide some refinement of the existing fundamental calculation formula by taking into account additional factors affecting the cooling process of the room. These include: taking into account the time of the initial irregular cooling process, taking into account the heat storage capacity of internal enclosing structures and furniture or equipment in the room, consideration of the initial temperature conditions in external and internal enclosing structures when calculating their heat capacity. The proposed approximate engineering technique is verified by comparing the calculation results with the results of direct calculation by the numerical method of the non-stationary thermal regime of the room in the full statement.
