Total assessment for various environmentally conscious techniques from three perspectives: Mitigation of global warming, mitigation of UHIs, and adaptation to urban warming

This study proposed a new system to assess the effects of countermeasures used to mitigate global warming and urban heat islands (UHIs) and to simultaneously adapt to urban warming. This system was used to investigate the impact of highly reflective materials and greening on the vertical walls of buildings, based on coupled simulations of radiation, conduction, and convection. Under the conditions assumed in this study, greening and highly reflective materials had a positive impact on the mitigation of global warming and UHIs. However, in terms of adapting to urban warming, greening was not very effective and the highly reflective material had a clearly negative impact.
