An Analysis of Residential Buildings under the Influence of Climate Change in the Coming Decades (Case Study: Residential Buildings of Eram, Tabriz)

Buildings presently use 30% of global energy, set to rise due to climate change. This study assesses climate change's impact on energy consumption(heating/cooling loads) in Tabriz over six decades. It also compares the effect of several energy efficient solutions in buildings. Future weather data for 2050 and 2080 was generated by CCWorldWeatherGen based on existing files. Identifying the prevalent housing type in Eram, energy simulations for the current and next 60 years used Design Builder 7.0.0.096. Applying energy reduction strategies, the study evaluates thermal performance, energy consumption, and environmental impact.In all models, heating peaks in 2020, and cooling surges by 28.69% and 63.34% in 2050 and 2080 versus 2020. Model WI shows the lowest cooling energy variation at 66.66%. COM models rank as the most efficient in 2020, 2050, and 2080, cutting energy consumption by 8.24%, 11.95%, and 12.83%.Climate change raises annual energy consumption by 4% in the current building model. Comparing strategies, two models—COM and thermal insulation WI—enhance building performance in 2020, 2050, and 2080. These findings stress the urgency of implementing strategies to mitigate climate-induced escalation in building energy consumption.
