Optimizing Natural Ventilation to Improve Energy Efficiency in Residential Buildings in Hot Climates in Abu Dhabi, UAE

Abstract

This research addresses the critical need to enhance energy efficiency and indoor comfort in high-rise residential buildings located in hot climates, focusing on Abu Dhabi (AD), UAE. With the increasing prevalence of full glass facades in such buildings, the demand for air conditioning (AC) rises significantly due to higher heat gain. This study aims to provide practical solutions for architects, engineers, and policymakers to optimize energy performance while ensuring occupant comfort and well-being through efficient natural ventilation systems. By investigating the potential of architectural passive design principles and natural ventilation strategies, the research seeks to minimize AC energy consumption by maximizing natural airflow. Methodologically, a mixed-method approach incorporating quantitative and qualitative analyses is employed. Utilizing tools such as questionnaires, documents, records, and case studies, the study examines the existing energy performance of buildings, identifying opportunities for improvement. Additionally, simulation tools like eQuest are utilized to model energy consumption patterns under various scenarios, allowing for the evaluation of different strategies. The research focuses on the hot and humid climate, particularly during peak months like August, using realistic weather data to inform the analysis. The findings underscore the potential of optimizing natural ventilation to alleviate the energy burden on cooling systems while maintaining indoor comfort. By identifying and implementing effective strategies, such as optimal operable window sizes and architectural design modifications, the study aims to contribute to the development of more sustainable and comfortable living environments. In conclusion, optimizing natural ventilation emerges as a promising approach to address energy efficiency challenges.
