Energy-Saving Regimes Examination During New Generation Building Structures Insolation

Abstract

High energy efficiency achievement isn’t possible without secondary and renewable resources using. One of the universally available alternative energy supply sources is solar radiation as it can be utilized in most Russian Federation regions with sufficient radiance duration. Along with it, active radiation converting systems into both thermal and electric energy imply significant financial investments that under unfavorable climatic conditions and negative weather factors, disrupting equipment functioning, can be recompensed during more than a decade. Solar energy passive utilization requires significantly less expenditure on necessary facilities, as building structures are used for the organization. The processes of external energy exposure of external panels with protective glazing influence on rooms’ microclimate have not been thoroughly examined. Typical daily variation in heat fluxes into such a type of solar panels that include different thermal properties building materials requires more extensive examination, including experimental ones. The results of thermal regimes measurements, generated during the cold period of the year into a structure that includes a layer of concrete, protected with an outer-walled double-glazed unit, air layers, and thermal insulation fixed on the inside of the outer panel are presented in the article. Results showed that, in case of relatively low solar radiation intensity, a panel is able to accumulate and give energy to the room, providing a positive daily balance. Achieved results, including ones obtained at temperatures below-15 °C, allow us to recommend solar panels of passive type using for a large part of the Russian Federation.
