Abstract

Currently, more than half of the world population live in cities (United Nations, 2021), and an increase in energy use in housing services is expected. Furthermore, cities are characterized by dispersed growth (urban sprawl), therefore, as a corrective measure the urban densification stra- tegy is introduced by city planners. The objective of this research is to analyze the impact of this strategy on Energy Use Intensity (eui) of homes in the arid climate and its relationship with den- sity parameters to substantiate the viability and improve the analysis and decision-making tools for the design of resilient cities. This study evaluates the use of air conditio- ning and heating through the selection of an urban analysis sample in Hermosillo, Sonora, from which densified hypothetical scenarios are generated and simulated through Energy Plus calculation tool. Finally, the results show the morphological parameters most closely related to consumption and indicate that the strategy can reduce eui by up to 37%. It is worth mentioning that the definition of the scenarios represents only a very small fraction of the almost infinite combination of parameters (geometry, climate, etc.) and is limited to the study of a single case. The research has a contribution in the development of city planning strategies, especially for those with an arid climate. In addition, also evaluates different levels of densification using common parameters and validates through an experimental methodology.
