Implication

Randomized trial evaluates energy savings and heat emission reductions in urban buildings, highlighting implications for microclimate management.

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.
