Comprehensive dynamic building simulations are used in order to conduct sensitivity analyses on the influence of building shell parameters to the heating and cooling demands of a variety of building types in Morocco. In a first step, five climatic zones are defined covering the range of specific heating and cooling demand combinations of a reference building located in eleven locations throughout Morocco. Afterwards, 22 single parameter variations for each building type and each climate zone are performed and analyzed in such a way, that suitable promising combinations can be defined as well. This procedure is faster and easier to analyze than a multidimensional regression. The results show indeed that the selected combinations may reduce energy demands substantially. This paper explains the procedure and results in detail for one residential type of building and for one typical non-residential building. The major overall results are discussed.
