Energy requirement, fuel comsumption and environmental impact of heating residentiel building - Case study of Fez

The seasonal energy requirements and fuel consumption for heating purposes in the residential buildings in the city of Fez is estimated from the predetermined architectural design and material characteristics of the buildings and the regular meteorological temperature measurements by using the degree-days method. The environmental impact of heating in term of equivalent CO₂ emission is also investigated for two sources of energy: liquefied petroleum gas and electricity. As a conclusion, the length of the heating period is average 194 days, and the mean heating degree-days value is found as 1039 besides changing between 895.8 and 1171. The heating energy requirement for the prototype building varies between 132 and 217 kwh/m² depending on glassing type, glassing area percentage and infiltration rate. In term of kgoe, electricity consumption is 2.6 times greater than that of LPG. By using LPG instead of electricity as a fuel, the emissions of greenhouse gases can be devised by 3.
