This article discusses the issues arising from irregular and excessive consumption of energy resources in cities across Uzbekistan, particularly in the context of overloaded infrastructure systems such as water supply, heating, and electricity. The authors introduce a new regulatory document focused on passive building strategies, which aim to utilize natural processes like solar insolation for heating and cooling, helping to mitigate the effects of climate change. The article proposes a novel approach for passive building design using the Giovanni diagram, a tool that aids in the development of bioclimatic zones. The study analyzes data from 2005 to 2022, collected from a meteorological station in Fergana, Uzbekistan, to map bioclimatic zones and optimize energy efficiency in buildings. The authors also present data models on solar heating and cooling systems, emphasizing the importance of natural ventilation, evaporative cooling, and high thermal mass for maintaining indoor comfort.
