Investigating the impact of forecasted and old weather data on the energy consumption of an educational building in different climates

Energy field studies and their calculation for the coming years in buildings show that the effects of climate change, especially the problem of global warming, play an essential role. This research includes two cities of Tabriz and Ahvaz with two different climates and a similar building under scenario A2 and two climatic data periods. It was used. The goal is to evaluate the impact of new and old data on energy consumption in the coming years. To predict climate data such as temperature, radiation, humidity, etc., from the CCWorldWeathergen software and also to prepare the 2TMY file from the TMY Creator software. used. Energy Plus software has been used to simulate energy consumption. The results show that using newer data provides a more accurate estimate than the old data. Due to the increase in temperature in the coming years due to global warming in the two cities of Ahvaz and Tabriz, energy consumption for heating and cooling will decrease. For this purpose, taking into account the hot and cold seasons in the forecast years (2080-2050-2020), it has been proven that for the city of Ahvaz during the year 2080 compared to 2020, a 24% reduction in heating energy consumption and a 5% increase in the cooling part, we will have a 19% decrease in heating energy consumption and a 7% increase in the cooling amount for the city of Tabriz during the year 2080.
