“…Consequently, these factors have had a significant impact on urban climates, exacerbating the heat island effect and contributing to the occurrence of extreme weather events [4,5]. These adverse effects, in turn, negatively affect the residents' health, air and water quality, as well as the buildings and infrastructure durability [6][7][8]. In response to the escalating urbanization rates, urban development strategies have gradually shifted from uncontrolled expansion to prioritizing high-quality and endogenous growth.…”

The escalation of anthropogenic heat emissions poses a significant threat to the urban thermal environment as cities continue to develop. However, the impact of urban spatial form on anthropogenic heat flux (AHF) in different urban functional zones (UFZ) has received limited attention. In this study, we employed the energy inventory method and remotely sensed technology to estimate AHF in Beijing’s central area and utilized the random forest algorithm for UFZ classification. Subsequently, linear fitting models were developed to analyze the relationship between AHF and urban spatial form indicators across diverse UFZ. The results show that the overall accuracy of the classification was determined to be 87.2%, with a Kappa coefficient of 0.8377, indicating a high level of agreement with the actual situation. The business/commercial zone exhibited the highest average AHF value of 33.13 W m−2 and the maximum AHF value of 338.07 W m−2 among the six land functional zones, indicating that business and commercial areas are the primary sources of anthropogenic heat emissions. The findings reveal substantial variations in the influence of urban spatial form on AHF across different UFZ. Consequently, distinct spatial form control requirements and tailored design strategies are essential for each UFZ. This research highlights the significance of considering urban spatial form in mitigating anthropogenic heat emissions and emphasizes the need for customized planning and renewal approaches in diverse UFZ.

With the expanding urban areas and increasing elderly population in Japan, anthropogenic heat poses substantial threat to human health. Air conditioning systems contribute to the anthropogenic heat from buildings. However, information regarding the heat characteristics of these systems is inadequate. In the present study, we developed a method for estimating anthropogenic heat from air conditioning, which accounts for most of the artificial heat from buildings during summer, to include artificial anthropogenic heat from surrounding buildings in the local heat risk assessment. The estimation results for commercial areas in Japan using the developed method showed that latent heat from air conditioning is substantially higher than sensible heat, and there was a difference in heat emissions between daytime and nighttime and between weekdays and holidays. A comparison of the calculation results of our method and those of previous studies showed no major differences in the orders of magnitude. With regard to the change in the amount of air-conditioning anthropogenic heat in the region, a directly proportional relationship was found between the outdoor temperature and the amount of air-conditioning anthropogenic heat. These results are useful for assessing the summer heat risk in urban areas and developing methods to mitigate the risks posed by urban heat.
