摘要：The data analysis results of long-term measurements of climatic parameters in Moscow and St. Petersburg is presented. The data on change in these parameters during the year over the past 10 years is exposed. The trends have been identified and represented for the following parameters: outdoor temperature, sunshine, snow depth, wind speed, humidity, etc. The duration of heating periods for each studied year and city is considered, as well as crossings through -2℃ during these periods. Throughout the research, the impact of climatic changes on the parameters of building climatology, which are used in designing the buildings and constructions in Russia, was determined. The obtained climate information will allow predicting the energy efficiency of operation for various engineering systems in the construction sector, as well as for the long term perspective.
