“…For the start and end of the air conditioning period: Note that the results in the two Tables 3 and 4 are comparable with each other and coincide with that of RETS screen, the differences either less or more because of the influence of global warming which has become a reality in Algeria [15][16][17].…”

For any new applicable and profitable investment in the thermal field of any region, we aim to eliminate or renovate conventional heating and air conditioning systems with new systems, which will work with new energies or renewable. First, you need to know the climate characteristics of these regions. In this study, we determine the diagnosis of the climate of arid and semi-arid regions, taking Ghardaï a as an example. These concerns air conditioning, heating, cold, ventilation, thermal water, for all this, we use the data from the two weather stations located on the Terrace of our research unit applied to renewable energies (URAER), Ghardaï a, for the last five years (2012)(2013)(2014)(2015)(2016), to calculate the day degrees heating and air conditioning (DJC and DJF) and the obtained results have been compared with the RET Screen motor from (1980_2006). Our approach allows us to discover a simple graphic method to characterize the seasons of Ghardaï a; applicable for any region around the world. In addition, it allows the real determination of the hygrothermal comfort of the region as well as the thermal characteristics of the MCPs adaptable to the Saharan climate.

“…In the particular case of the Mediterranean region, buildings are more prone to overheating than in northern European countries, thus leading to higher cooling demands; which is a rare issue in those countries. There are several studies regarding the optimal energy performance values for the envelope elements of buildings in the Mediterranean region: for example, Tsikaloudaki et al [7] assessed the window's contribution to the energy performance of buildings in the warmer regions of Europe. The authors carried out a parametric study by varying the window's glazing area, U -value, and g-value in a reference room with residential and office use profiles.…”

The impact of thermal transmittance variation on building design in the Mediterranean region

et al. 2019

Contrarily to what happens in northern European countries, buildings in the Mediterranean region are prone to overheating. Consequently, it is important to better understand the role of thermal transmittance of the building envelope elements in the airconditioning consumptions. This paper analyzes the effect of different U-values on the building design in the Mediterranean area. 192 000 residential buildings were randomly generated and the energy consumption assessed for sixteen distinct locations. It was found that, in northern Mediterranean locations, as U-values decrease, the energy consumption also decreases. However, in warmer climates, low thermal transmittances tend to significantly increase the energy consumption. Hence, the lower the latitude, the higher the most adequate U-values, due to the increase of the cooling demands. Additionally, geometry-based indexes were correlated with the buildings energy performance. For high U-values it was found that bigger buildings worsen the energy performance and larger windows tend to improve it. For low U-values, bigger North-faced windows are beneficial. There is an adequate interval of values for which the geometry has a lower impact, which is wider and higher for lower latitudes, thus meaning that not only the building performance improves but architects are also freer to explore alternative designs.

“…U-value and g value influence the heating and cooling demand in a residential building in northern and southern climate in Korea [24]. Furthermore, Tsikaloudaki et al [25] also conducted a parametric study on the energy performance of windows to investigate the influence that the thermal and optical properties of glazing have on the cooling demand. Different window cases were also compared on the performance of daylight and thermal comfort [26,27], which focused more on office buildings.…”
