| Popis: | This study presents the first results of multi-objective optimization of typical four-room rural residential buildings in Uzbekistan with different levels of thermal insulation. For that purpose, a simplified static model of buildings based on the heating degree-days has been employed and the optimal designs were found for three scenarios. In the first scenario, the life-cycle cost of the reconstruction measure was analyzed where the optimal thicknesses of the insulation layer were found for the roof, floor, and external walls but no solutions were found for windows, solar collectors, and photovoltaic (PV) panels. In the second scenario, primary energy consumption was minimized to zero for space heating and domestic hot water. In this scenario, the thickness of insulation layers for building envelopes and the size of solar collectors were optimized in various regions. In the final scenario, low carbon communities were considered in technoeconomic conditions of Uzbekistan. However, no optimal solutions were found in the current cost of electricity. |
