Geothermal Energy Use for the Additional Heat Supply of a Residential Building

Abstract

To ensure low-energy consumption in new generation energy-efficient houses, the technology of a ground heat exchanger with a heat recovery system is used almost everywhere. However, this technology has not been widely disseminated in Ukraine. The work is aimed at presenting insights from research on the combination of ground heat exchangers with a heat recovery system for building ventilation by analyzing the operational and techno-economic indicators obtained. Current studies permit revealing the optimal configuration of a ground heat exchanger with a heat recovery system for ventilation in a residential building in order to analyze the efficiency of ground heat exchangers with a heat recovery system for ventilation of a residential building in comparison with several conventional ventilation options to assess the main price/ performance ration of the process of constructing a ground heat exchanger with a heat recovery system and to determine the duration of the technological process, the labor-intensive characteristics, and the estimated cost of the technology.

Residential Energy-Saving Lighting Based on Bioinspired Algorithms

“…e function of the input layer is to receive the input model data and transmit it to the hidden layer. According to the residential energy-saving lighting requirements, it can be seen that the efficiency of lamps, luminous flux of light source, average reflectance ratio of wall surfaces, the installation height of lamps, working area, maintenance coefficient of lamps, effective floor reflectance, and effective ceiling reflectance have a significant impact on residential energy-saving lighting [17][18][19][20][21]. erefore, the above 8 types of data are selected as input data, and the number of neurons in the input layer is 8.…”
