Albanian Building Stock Typology and Energy Building Code in Progress Towards National Calculation Methodology of Performance on Heating and Cooling

The expertise on building stock typology used openly available data from the Albanian statistical office. As the CENSUS was not especially designed for gathering data for the energetic evaluation of the building stock, some data were not available on the required level of detail. Estimations were necessary to extrapolate data to the existing stock. Technically, the study selected and described twenty representative categories of residential buildings typology for Albania. Were identified the level and the structure of final energy consumption at present and in the future by building age category, building type, climate zone, and energy end-use. Using an original template excel data sheet, were conducted the calculations of their thermal energy performance in three climate zones, designed standardized retrofit packages, calculated possible energy savings, and investment required by building type. The engineering principle of the Regulation in force, regarding to the legislative act of Energy Building Code in Albania, is beyond any doubt correct and carefully studied. The act is a rule book or the Regulation (energy building code - here The Code) which contains information that is sufficient to perform calculations of the different insulating layers for new construction after the year 2003. Also, the Regulation’s algorithms are still relevant in terms of calculation to provide Energy for heating demands in Albania. After 12 years, the Code remains the same and could provide either an optimal potential energy savings to the existing buildings, or an optimal cost-effective of building’s insulation without imposing a burden of high financial housing builders to multifamily prospective buyers. Based today Europe’s developments on Energy Performance of Buildings, the study is found relevant to provide a methodology for calculation of the energy performance in buildings (kWh/ m2a) based on volumetric coefficient heat losses (Gvt) for heating only, the existing indicator of the existing Code. The following study deals with the possibility of transposing the methodology used to the Code into an energy Performance based on minimum requirement for a new Regulation and/or EP Calculation Methodology based on efficient use of energy for heating and cooling purposes.
