TY - JOUR TI - A new modelling approach of a multizone building to assess the influence of building orientation in Saharan climate AU - Hamdani Maamar AU - Bekkouche Sidi Mohammed El Amine AU - Benouaz Tayeb AU - Cherier Mohamed Kamel JN - Thermal Science PY - 2015 VL - 19 IS - 12 SP - 591 EP - 601 PT - Article AB - Orientation of building is a very important factor which is directly connected to the standards of thermal comfort within building. It is guided by natural elements like sunlight and its intensity, direction of the wind, seasons of the year and temperature variations. The orientation effect of a non-air-conditioned building on its thermal performance has been analyzed in terms of direct solar gain and temperature index for hot-dry climates. This paper aims at introducing an improved methodology for the dynamic modeling of buildings by the thermal nodal method. The evaluation is derived from a series of computer simulations. As a result, the influence of orientation changing depends on the floors and exterior walls constructing materials, the insulation levels and application of the inseparable rules of the bioclimatic design.
