Comparative Study of thermal behaviour of two types of apartments located in Casablanca

In the current energy context, significant reductions in energy demand must be made in the building sector which is the biggest energy-consumer among all economic sector and whose consumption can be greatly reduced through the promotion of low energy buildings obtained from the optimization of the envelope and which is an effective way to reduce emissions of greenhouse gas and slow the depletion of non-renewable energy resources. In Morocco, where the energy bill weighs heavily in the trade deficit, the building sector alone accounts for approximately 36% of final energy consumption. A part of this energy is used for space heating and air conditioning. If we then act on the heat inputs and losses of the building, so it is energy efficient, we can reduce energy consumption of this sector. Thus the objective of this work is to study the effect of thermal insulation on the house cooling and heating loads by comparing two types of buildings simulated by TRNSYS, the first is a building which presents the typical construction, the most common in Morocco, and which is considered as a reference and the other one is a building of the project FAL AL HANA located in Casablanca which the envelope is insulated.
