Influence of buildings aerodynamic characteristics on the calculation of infiltration losses results

Abstract

This work is devoted to the problem of studying the energy efficiency of buildings, in particular - the definition of infiltration losses. The article presents the main methods for determining infiltration, which are presented in SP 50.133330.2012 and GOST R 55656-2013. However, the infiltration of air through the building envelope depends largely not only on the structural and planning features of the building, installed equipment, etc., but also on the environment, the climatic characteristics of the region in particular the effect of wind. In this regard, the staff of the Educational, scientific and industrial laboratory for aerodynamic and aeroacoustic tests of building structures of the NRU MGSU developed an addition to the existing established algorithms for calculating infiltration using the data of the experimental wind impact study, which is presented in this paper. The publication contains a description of the main stages of the implementation of this type of work.
