Influence of the compactness index to increase the internal temperature of a building in Saharan climate

This paper introduces a new approach to the description and modelling of multizone buildings in Saharan climate. Therefore, thermal nodal method was used to apprehend thermal behaviour of air subjected to varied solicitations. The result proves that proper use of compactness index and building geometry parameters will noticeably minimize building energy and improve the internal temperature of the building. The compactness is better when the compactness index is lower.
