Optimization of shape and functional structure of buildings as well as heat source utilisation. Partial problems solution

摘要

The aim of the paper is to present rational methods of multicriteria optimization of the shape and structure of energy-saving buildings, as well as optimization of heat sources taking into account the energy criteria. Mathematical model describing heat losses and gains in a building during the heating season was selected and refined. It takes into consideration heat losses through walls, roof, floor and transparent partitions as well as heat gains due to insolation across transparent partitions. Particular attention was paid to a more detailed description of heat gains due to solar radiation, depending on the position of partitions relative to their north-south axis and the degree of their use.
