Predicting Energy Requirement for Cooling and Heating the Building Located in South West of Algeria (Bechar)
Keywords:building, cooling, heating, temperature, Trnsys
In buildings, many factors influence the energy performance, such as ambient weather conditions, building structure and characteristics, lighting, equipment, occupants and their behavior. This makes the situation complex to accurately predict the building energy consumption and its behavior. The objective of this piece of work is to contribute to the improvement of the energy efficiency of the residential buildings located in Algeria’s southern west city of Bechar. In this study, we are trying to calculate the energy consumption for both cooling and heating in Bechar house. The simulation was conducted using TRNSYS program within one year through two different scenarios. The results obtained, revealed that the cooling load reached 12.223,30 KWh per year when the internal loads has been taken into account, the energy requirements for cooling the building present almost 69.51% of the total needs and the demand for heating presents 30.49% per year.
