Klymovych I. Energy efficiency of low-rise residential buildings of architectural constructive systems

The research is aimed at scientific statement development of rational design of energy efficient low-rise residential buildings based on the laws of the object energy efficiency dependence according to the architectural and structural systems. The following scientific and practical results are given in the dissertation on the basis of the numerical experiment: - ranking of low-rise buildings by all energy efficiency classes for all temperature zones of Ukraine has been made for the first time; - specific heat consumption data of low-rise residential buildings with different architectural and structural systems have been calculated and classified; - energy efficiency change regularities of one-, two-, three-, and four-storey buildings from their architectural and structural systems for all temperature zones of Ukraine have been determined; - the system of specific heat consumption indicators, consistent with the applicable element wise requirements to heat transfer resistance of the houses walling, has been suggested for all the temperature zones of Ukraine. The thesis presents an improved method of rational design of energy -efficient low-rise residential buildings according to their life cycle. The mathematical model for finding the optimal version of draft power-efficient residential building has been developed. For conditions of Dnepropetrovsk the optimization problem has been set and solved (finding the optimal version of the draft energy-efficient buildings). The calculations prove the fact that the construction of passive houses in Ukraine today is economically feasible only within the interest-free loans. Scientific and practical regulations, outlined in the thesis, can be used by all participants of the investment programs, and energy-efficiency projects, and developing normative-technical documents. Key words: energy efficiency, low-rise residential buildings, architectural and structural systems, specific heat consumption, rational design, life cycle of buildings.
