The evolution of air temperature and energy consumption in a region of the Wilaya of Nouakchott using the TRANSYS program

Abstract

Global energy demand in the building sector has continued to grow rapidly in recent years, making it one of the main contributors to reducing energy expenditures and greenhouse gas emissions, this leads to uncomfortable and energy-intensive buildings, and the excessive energy consumption is a reality in buildings. The following work aims to reduce this energy consumption and improve the energy efficiency of buildings. Optimizing thermal insulation is the only way to ensure this efficiency. Building energy performance simulation is becoming increasingly important in the design and analysis processes of buildings worldwide, which is why TRANSY simulation software was chosen because of its various advantages.

The results of the simulation showed after studying the variation of air temperature in an area of the Wilaya of Nouakchott for three different cases, in the absence of heating and air conditioning, the temperature is very high in summer and very low in winter.

Temperature changes in heating and air conditioning systems according to human needs to provide thermal comfort. Temperatures are reduced and maintained appropriately inside buildings in summer and winter to achieve a moderate atmosphere and thermal comfort thermal analysis is used. It has also been shown that the application of thermal insulation in buildings reduces energy consumption.
