ABSTRACT
Nowadays the construction in Morocco is poorly adapted to the climatic conditions of the country. This contributes to the increase of electricity demand by 7% annually. The Department of Energy is interested in introducing sustainable construction for large construction programs in Morocco. Especially as there is a large demand for new buildings and then the general goal is to build them energetically more efficient than in today’s practice. To reach the said goal, energy demand of the building shall be minimized without trading off the environmental comfort for living. The dynamic building simulations are done to determine the thermal performance of the building by TRNSYS simulations in order to conduct analyses on the influence of building shell parameters to the heating and cooling demands. Thus, the improvement of the passive building energy efficiency. A building thermal energy model is used for this purpose.
The study is carried out on a prototype of an office building in the city of Tetuan in northern of Morocco. This paper explains the procedure, simulations results in detail, discusses the major overall results and the effect of the building refurbishment steps in comparison with the Thermal Building Regulations in Morocco.
