Abstract
This article investigates the impact of climate change on energy consumption in residential buildings across various Iranian cities over the next 70 years.
To achieve this, climatic data for Tehran, Tabriz, Isfahan, Mashhad, and Kermanshah were generated using Meteonorm 8 software based on existing ten-year climatic data. Following the identification of prevalent residential building types in Iran, a representative sample was selected, and energy simulations were conducted using Design Builder 7.0.0.096 software for the years 2030, 2060, and 2090 in the aforementioned cities.
The results indicated a projected increase in cooling energy demand across all cities in the coming years. Tehran exhibited the most significant changes in annual heating energy, with a projected decrease of 37% in 2060 and 66.64% in 2090 compared to 2030. Tabriz experienced the largest annual increase in cooling energy, with a rise of 37.53% in the first three decades and 75.43% in the subsequent three decades. Overall, projected annual cooling energy changes ranged from 21.36% to 37.53% by 2060 and 44.14% to 75.43% by 2090 across these cities.
Tabriz had the highest annual energy consumption, while Kermanshah had the lowest. Additionally, Tabriz exhibited the highest heating energy consumption, whereas Tehran had the highest cooling energy demand annually. Regarding carbon dioxide emissions, Tehran recorded the highest levels during 2030, 2060, and 2090, with Isfahan showing the most substantial increase in emissions over the seventy-year period. Statistical analyses revealed a significant relationship between temperature changes and time across all cities. However, no significant relationship was found between time and energy consumption or carbon dioxide emissions in these cities. In conclusion, this study highlights the anticipated changes in energy consumption and carbon dioxide emissions in residential buildings across Iranian cities due to climate change.
