| Abstract [eng] |
Factors of significant impact on the overall energy efficiency potential of the building are decided in the early stages of the design. In the early stages of design, design modifications are quite frequent, therefore contemporary time-consuming methods for determining the optimal energy properties of a building may miscalculate the impact of the proposed solutions. In order to avoid the contradiction and to evaluate the impact of the building shape on the energy efficiency, architects and engineers may use simply expressed and perceived shape compactness indicators. The research of a real administrative building in the city of Kaunas was carried out in the master's thesis. The research methodology is based on the concept and results of the initial research. Dynamic energy simulations for energy models of real, I-, L- and U- shaped building alternatives in four different orientations were performed with IDA-ICE dynamic energy simulation software. It was determined that the length ratio of the shading and shaded facades and the orientation of the building have negligible impact on the consumption of thermal energy and electric power consumption. The ratio of the building envelope area to inner volume and thermal energy consumption were found to be linearly dependent, however, no significant correlation to electric power consumption was found. |
