MODELING TRANSMISSION HEAT LOSS UNDER VARIATIONS IN THE GEOMETRIC SHAPE OF GREEN BUILDINGS

The relevance of quickly determining transmission costs under variations in the geometric shape of green buildings for modeling a certain level of energy efficiency is due to the need to respond promptly to changes that arise during the design of new, reconstruction, additions or modernization of existing buildings. Changing the geometry of buildings affects their thermal insulation characteristics, and therefore, the level of energy costs, which determines the efficiency of energy use for heating, cooling and lighting. In the context of "green" construction, where the key factor is the achievement of high energy efficiency standards, quick and accurate determination of transmission costs is critically important for modeling the energy behavior of a building. This allows for timely adjustment of design solutions, assessment of the impact of changes on energy consumption, and also increases the accuracy of energy efficiency prediction under different operating conditions. Thanks to the rapid determination of transmission costs, it is possible to provide optimal conditions for achieving a certain level of energy efficiency, reducing energy consumption and reducing greenhouse gas emissions. This contributes to sustainable development in the construction sector, in particular, in the context of implementing the principles of sustainable construction and ensuring environmental safety at the global level. The article conducts research and determines the compactness of various geometric shapes of buildings. The conversion factor nv of the change in the compactness of the building when changing the volume of the building is determined, provided that the geometric shape of the building is preserved. The study is conducted and a method is proposed for quickly determining the change in the level of transmission costs by using the rational geometric shape of a green building. The weighting factors of transmission heat loss when varying the geometric shape are determined. The results of the study can be used in design practice and the educational process by students when developing projects for energy-efficient green buildings.
