Over the past few decades, the world has seen a major population movement to metropolitan regions. About two-thirds of the world’s total primary energy consumption is used in urban regions, with buildings making up a large portion, approximately 40%. A key component of creating sustainable cities is the accurate assessment of building energy use and corresponding CO2 emissions. Urban Building Energy Modelling (UBEM) has gained immense popularity recently; however, the existing state-of-the-art methodologies and tools for estimating urban-scale energy usage do not best comply with different environments. While well-structured UBEM models exist for the West, they still need to be devised in the context of Global South countries. This article proposes a bottom-up UBEM methodology for urban energy use modeling (UEUM) in the case of Pakistan. An extensive literature review was conducted to facilitate the review and assessment process, enabling the identification of various methods and approaches utilized in urban energy use modeling. Subsequently, the results of this review process were analyzed, and the challenges associated with implementing UBEM in Pakistan were elucidated. Based on this analysis, the most viable methodology and approach for UBEM in the Pakistani context is proposed. Therefore, this research guides planners, practitioners, and energy policymakers as they select the best strategies to create and carry out comprehensive sustainable building energy planning and analysis projects in Pakistan and other countries of the Global South.
