Characteristics of Urban Heat Island in China and Its Influences on Building Energy Consumption

Urban heat island (UHI) draws more attention as it affects not only the health of residents but also energy consumption buildings at city scale. To achieve carbon neutrality goals, is crucial to better understand mechanism UHI influences on building consumption. The characteristics urban intensity (UHII) and relationship between UHII effect electricity related coal were analyzed, based long period monitoring data with hourly weather from 1 January 31 December 2019. Results show that a strong correlation annual mean median daily exists. synthetic diurnal most cities presents U-shaped variation trend. In different climate zones in China, namely, severe cold region (SCR), (CR), hot summer winter (HSCWR), warm (HSWWR), mild (MR), analyzed. existence reduces 96.7% SCR 60.8% CR cities, while HSCWR, HSWWR, MR percentage where increased by 69.4%, 80%, 63.6%, respectively. strongly consumption, indicating should be considered analyzed detail for making future development or emission reduction strategies.
