Exploring Energy Efficiency in Historical Urban Fabrics for Energy-Conscious Planning of New Urban Developments.

The global rise in urban energy demand poses severe environmental and economic health challenges. We need adaptive policies in urban planning to reduce the need for urban energy. This has become a prominent agenda in urban planning, encompassing social (education and innovation in consumption), economic (real pricing), and physical (urban morphology) aspects. This research aims to investigate the influential role of urban form, particularly the physical environment, on energy performance. The methodological approach is centered on conducting analytical-comparative research to examine how urban form influences theoretical energy requirements. Yazd City is selected as a case study because of its distinctive features and traditional approaches to urban sustainability, which have been largely overlooked in previous energy consumption investigations. In a broader comparative context, five tissue types (morphological units) have been selected from Rome, Barcelona, Madrid, and Venice and used as the analytical basis of the study. The research categorizes urban forms into three levels: macro (fabric), medium (block), and micro (building patterns). Heating, cooling, and total energy consumption were computed at each level. The findings indicate that, at the macroscale, the Barcelona fabric offers the highest potential for adaptation in the hot, dry climate of Yazd City. Moreover, the paper analyzes the most recurring morphological indices in the tissues and proposes guidelines for new developments tailored to Yazd City's unique climatic conditions. By focusing on urban form's impact on energy performance, this research contributes to the broader understanding of sustainable urban planning. It offers valuable insights for energy-sensitive urban development in other contexts facing similar climate challenges. [ABSTRACT FROM AUTHOR]
