Improving energy efficiency while reducing anthropogenic heat from buildings: how retrofits influence the building stock and urban microclimate in Los Angeles

Key Points

• The aim is to evaluate how building retrofits can enhance energy efficiency while minimizing heat emissions.
• Evaluated various building retrofit measures for energy conservation and heat emission reduction.
• Assessed the impact of retrofit packages on city-wide summer energy use and anthropogenic heat emissions.
• Developed an integrated framework for retrofit planning and urban heat mitigation.
• Optimized retrofit measures can reduce city-wide summer building energy use by 32%.
• Adding roof coatings can decrease anthropogenic heat emissions by over 50%.
• Implementation of these strategies can lower peak summer air temperatures by up to 3.79°C.
