Abstract

This thesis analyzes the impact of urban built form on energy consumption for indoor cooling in regions with very hot climate. While high building density increases shading on buildings and in turn decreases energy consumption for cooling, the internal heat gain resulting from a larger population has an adverse effect on cooling load. We use Abu Dhabi’s weather data to analyze the cooling load required to sustain thermal comfort for optimal health and productivity in a set of urban design schemes that vary by thermal isolation requirement, building height, and building density. The objective is to explore the effects of urban development options such as population density, indoor temperature set point, the number of working hours, thermal insulation level of the envelope and lighting power intensity on energy efficiency for cooling in the building systems. While the analysis results are sensitive to weather conditions, it shows that the optimal urban built form in terms of sustaining resident health and productivity at minimum energy consumption for indoor cooling can be identified by balancing shading and internal heat gains.
