AbstractAbout AuthorsReferences
The relevance of the study is related to the need to take into account heat gains from solar radiation when assessing the energy saving class of a building and the incompleteness of information about such heat gains in the current regulatory documents of the Russian Federation. The subject of the study is the dependence of the specific character of heat access to the building from solar radiation on the geographical latitude of the construction area. The purpose of the study is to estimate the total orientation-averaged specific heat gains from solar radiation during the heating period. The objective of the study is to obtain analytical expressions for the heat flow per unit area of glazing and degree-days of heating period, depending on the latitude and other settings. A comparison of correlation dependencies was used to identify the statistical relationship between the parameters of the heating period and the geographical latitude of the construction area within the main part of the territory of the Russian Federation. It is shown how, taking into account the obtained ratios, it is possible to use information on the specific heat flow from solar radiation through vertical translucent barriers, provided in SP 131.13330.2012, for the approximate calculation of the specific characteristic of heat access to the building from solar radiation. The engineering dependence of the averaged total specific intensity of solar radiation on building facades is obtained, depending only on the geographical latitude of the area.
