Abstract
Today, the issue of improving the level of energy efficiency of existing and construction of new energy efficient buildings is an urgent issue in Ukraine. Improving the energy efficiency of existing buildings is possible due to their thermal modernization, which requires the creation of ways to determine the rational and optimal parameters of the thermal insulation shell of buildings in order to increase the level of energy efficiency of buildings in accordance with modern requirements.Analysis of the studies showed that the thermal balance of translucent and opaque structures of the building depends on the parameters of the spatial orientation (azimuth, slope), the heat transfer resistance and the area of structures. Given the geometric shape and azimuthal orientation of the building, the variable parameters are the heat transfer resistance of opaque and translucent structures. as well as their area.The complex of graphical models for determination of rational (close to optimal) geometric parameters of thermal insulation shell of buildings with consideration of heat losses and heat inflow from solar radiation through fencing structures is developed for use in thermo-modernization of existing buildings and construction of new energy-efficient structures on the level of construction current regulatory requirements.The drawings of the building are used to determine the rational heat transfer resistance and the location of windows on the faces of a faceted building along with the resulting graphic models Rвpi = f (Аσ). In this case, the building plan is combined with the models, and the designer in a dialog mode with the computer determines the rational level of resistance to heat transfer of translucent and opaque enclosing structures.Model analysis confirmed that in all natural and climatic regions of Ukraine, the thermal balance of translucent structures is significantly influenced by heat transfer resistance, the g-factor of glazing, and the orientation of translucent structures.
