Over the past decade, global temperatures have surged by 1.09 °C compared to the late nineteenth century, marking unprecedented levels. The last five years have been record-breaking in terms of heat. Scientists predict further increases of over 1.5 °C by the mid-2030s. While factors like urban climate, human behavior, building equipment, and neighborhood design all affect energy use, the specific impact of neighborhood layout remains unclear. This study aims to optimize urban neighborhood layouts for energy efficiency, maximizing photovoltaic potential and minimizing carbon emissions. It explores how different weather conditions affect optimal designs to find solutions with the lowest energy use and emissions.
