In cities with developed infrastructure, this factor exposes the additional load or its reduction caused by heating and air conditioning systems in residential, industrial, commercial and office buildings. The impact of climate change on urban energy consumption is a latent characteristic that does not stand out directly from meteorological, statistical, or any other data. Some of Russian cities are used to discuss the possibility of its detection.
