Investigating the effect of new and old weather data on the energy consumption of buildings affected by global warming in different climates

Energy assessments and studies for the coming years in buildings show that the effects of climate change, particularly the problem of global warming, play an important role in increasing the accuracy of these calculations. A similar educational building in two different cities, Tehran and Tabriz, was considered in this study. The goal was to investigate and assess the impact of new and old data on predicting energy consumption in the coming years. The Typical Meteorological Year data was prepared using a Typical Meteorological Year data Creator software. To simulate energy consumption, the Energy Plus software was also used. Taking into account the hot and cold seasons in the forecasted years (2020–2050–2080), this issue has been proven so that for the city of Tehran in the year 2080 compared to 2020, there will be a 24% reduction in energy consumption in the heating part and a 5% increase in the cooling part. In addition, for the city of Tabriz in 2080, we will see a 19% reduction in heating energy consumption and a 7% increase in cooling energy consumption. It should be noted that, using more recent data produces estimates that are more precise than those produced using older data. Furthermore, as temperatures rise in the coming years as a result of global warming, heating will decrease and cooling will increase in Tabriz and Tehran.
