Integrating Climate Change Adaptation into Building Design Codes: A Focus on Multi-Story Residential Buildings in Iran
| Resumo: | Building energy consumption and CO₂ emissions in the Middle East exceed global averages, with Iran’s residential sector consuming five times more energy than the world average. Decades of energy subsidies have discouraged energy-efficient design, leading to excessive reliance on mechanical cooling. As climate change intensifies and temperatures rise, cooling demand will escalate, particularly in poorly insulated buildings, further exacerbating energy inefficiency. Addressing this challenge requires immediate action to enhance thermal performance and reduce dependence on mechanical cooling through climate-responsive design strategies. This study aims to develop climate-responsive design recommendations for multi-story residential buildings in Iran by evaluating the effectiveness of different envelope strategies under present and future climate conditions. A validated real-case apartment model was used to simulate energy demand across Iran’s major climate zones, utilizing EnergyPlus for energy simulations. Future weather data was generated using the EC-Earth3 model through the Future Weather Generator tool, ensuring reliable climate projections for the 2050 and 2080 timeframes. A sensitivity analysis was conducted using the Morris method to identify the most influential thermal envelope parameters. The top-performing energy-efficient cases from the sensitivity analysis were then compared with existing building code requirements to propose targeted envelope design strategies. The results reveal that Iran’s current energy efficiency standards are insufficient to meet both present and future climate challenges, highlighting the need for stricter policies and revised climate zone classifications. To address this, the study presents an updated, structured framework of climate-responsive recommendations to improve resilience to future climate conditions while increasing energy efficiency. This framework provides clear guidance for architects, designers, and policymakers, supporting the development of energy-efficient, climate-adaptive buildings in Iran and other regions facing similar challenges. |
