Martynov V. Modeling optimal geometric parameters of power-efficient sided-shape buildings

The paper deals with the development of the theory of geometric modeling optimal geometric parameters of power-efficient sided-shape buildings from the point of view of the optimal environment heat and power impact on the heat balance of buildings. Regularities of the environment heat and power impact on the geometric parameters of the buildings have been researched. Regularities enabling optimization of the building parameters, distribution of the heat insulation and placement of windows in their heat-insulated shell, etc have been determined. Computer models for calculation of incoming solar radiation with increased performance, thermal losses and heat input through translucent and opaque protective structures, oriented to the solution of multi-parameter optimization problems in construction, in particular, concerning optimization of proportions, sided shape of detached and blocked power-efficient buildings, heat insulation parameters, placement of windows, suntrap, at the protective structures, optimization of orientation of buildings with a discrete variation of orientation during a day or a year, as well as fixed ones, have been developed. Geometric modeling of a number of problems in construction climatology, heating and lighting engineering has been carried out to determine optimal geometric parameters influencing the building power efficiency. The results of the paper have been introduced into national regulations on issues related to energy saving during the design and reconstruction of buildings; into guidelines for training specialists in architectural line in Ukraine; into practice of architectural-construction design in Ukraine, the Russian Federation and Saudi Arabia.
