The Effect of Opposite Buildings on Energy Saving of Buildings with Low-Emission Glazing

Currently, theoretical approaches to the optimal choice of energy-saving structures are being developed. Thus, for translucent enclosing structures, criteria have been developed for the selection of energy-saving glazing based on a number of parameters: thermal, energy and lighting. The paper considers the criterion for choosing low-emission glazing, which provides an optimal ratio of transmission heat loss and heat gain from solar radiation. Calculations carried out according to the criterion are based on calculating the ratio of the difference in transmission heat loss when using glazing without coatings and with energy-saving coatings to the difference in heat gain from solar radiation when using the same types of glazing. However, this criterion is designed for a single-standing building. In the presence of an opposing building, the incoming solar radiation changes, therefore, the values of the criterion change and the choice of energy-saving glazing should change. In this paper, the influence of the opposing building on the value of the criterion and the choice of energy-saving glazing is determined when changing a number of parameters: the distance between buildings, the weighted average albedo of the facade of the opposing building, etc. The calculation was carried out according to the proposed criterion for two cities of the Russian Federation located at the same geographical latitude, but having a different climate. It is shown that the considered parameters related to the opposing building affect the choice of low-emission glazing.
