It consists to taking into account both architectural and thermal aspects for new and old construction. With the use of energy wall systems, it is possible to reduce the heating/cooling demand of energy consumption and evaluate the indicators of energy performance. In doing so, this work can contribute not only to long-term economic growth, but also help address pressing social, including on a wide range impact environmental. We use a dynamic simulation with a structural equation modelling to test the hypothese on a data base of climate of this region. The final part consists technico-economic approach, calculating the investment costs analysis, comfort and energy saving. The results demonstrate its utility in explaining, regarding high systems availables in innovation performance.

This situation produces enormous energy consumption while the application of thermal regulations was not valid for the entire construction. This article aims to use passive strategies inspired by vernacular architecture, to arrive at passive and ecological houses. Initially, this work consists of knowing the different traditional or current systems used specifically in arid and semi-arid regions. Then, the methodology followed based on a dynamic simulation of the strategies applied in an existing apartment located in the south of Algeria (case study). Afterwards, we will provide a multi-criteria and cost-benefit analysis, to validate an appropriate optimal model, based on energy savings and investment cost. In conclusion, it was observed that using the waterspout wall with night ventilation could reduce energy consumption by 50% and maintain thermal comfort.

A ce propos, des simulations ont été effectuées à l'aide du logiciel de simulation du comportement thermique en régime dynamique 'TRNSYS 16' avec le modèle numérique type 56. Ce projet vise l'introduction des matériaux de construction isolants, afin d'améliorer le confort thermique et de réduire l'énergie consommée. Diverses variantes ont été proposées, qui permettent de faire un choix pertinent assurant un meilleur confort thermique tout en étant très peu énergivore.

Research paper thumbnail of Does the shared vision of social identities influence the quality of civil construction by reinforcing the type of thermal insulation, and by creating or improving thermal comfort?

This article aims to study the influence of the shared vision of social identities on the quality of existing civil constructions by reinforcing the type of thermal insulation to achieve better thermal comfort for individuals regardless of the conditions climatic. To do this, we first presented a general description of the current context of construction and the available materials used in the city of Bechar. Then a general analysis on the different techniques induced in the construction of the envelope (exterior walls and roofs) in order to select the best technique that adapts to the climate of Bechar (hot and arid) and strengthening it to improve the thermal comfort of residential homes with lower energy consum...

Il consiste à évaluer le confort thermique des habitants, et réduire la consommation d’énergie, répondant d’abord aux normes minimales du logement à cette région, surtout en période estivale. À ce propos, une méthodologie de recherche proposée pour cette étude ; la première est une investigation subjective achevée à l’aide d’un questionnaire comme outil de recherche. Tandis que la deuxième est un travail expérimental et une analyse comparative entre des résultats expérimentaux et de simulation. L’analyse montre que la majorité des habitations semblent inadaptés à la rudesse du climat, où l’enveloppe provoque un environnement thermique interne très sévère. Les bâtiments résidentiels sont devenus énergivores, conséquence de l’inadaptation de ce type d’habitation au climat chaud. Cela est dû à l’utilisa...

To do this, sustainable strategies must be applied for tertiary buildings. The methodology consists to evaluate these passive strategies by covering three proportions of sustainability (energy, economic and comfort), with a dynamic simulation. In addition, to calculate energy performance and energy savings indicators, we are carrying out a survey to establish reasonable and fair criteria for case study. In this study, four stages were carried out data collection and analysis, evaluation of the energy performance indicators of the strategies. With a multi-criteria analysis, we can evaluate indices of the energy performance of a building, in order to set up a new energy certification, which can allow energy savings and maintain comfort.

The main objective of this research is to adapt the traditional strategies in the architecture actual, to achieved a thermal comfort and improve on reducing cooling load through the using of vernacular gait. Today, it is necessary to practice these systems in the current or conventional architecture of household. The study is especially for arid cities namely the region of Saoura, in the hot and dry climatic zone in Algeria, considered for this study. Two main factors is considered such as design and urban where taken into account in order to select the appropriate and specific passive cooling strategy. The results show that the passive cooling strategy of courtyard would be appropriate for arid regions, however a high thermal mass would be suitable for construction. In conclusion, this work made it possible to choose a suitable passive cooling strategy for all types of construction in hot and dry climates. Finally, this paper puts forward a set of recommendations to improve the passive design of future buildings in hot and arid climates.
