Abstract: Wetland parks can cause cooling effects on urban areas, which would change the corresponding building energy consumption (BEC). This study aims to predict BEC indexes by considering the wetland park cooling effects. Ten typical wetland parks in Guangzhou, China, were selected, and the 600m radius built-up areas involved 30 buffers are classified by local climate zone scheme. BEC indexes of these built-up LCZs were assessed through the Energyplus™ software based on air temperature obtained from the land surface temperature retrieved from remote sensing image of Landsat 8. Linear regression formula was used to analyze the relationship between BEC and park cooling indexes. Considering four shape and six landscape parameters of wetland parks and six urban morphological parameters, a statistical linear model reduction method is used to assess BEC based on the factor that its contribution percentage was higher than 0.1 %. The results showed that these factors can predict BEC with R2 higher than 0.97. The PAR and SI contribute 20.8 % and 21.9 % to the total average BEC within park cooling ranges. The urban morphology contributes 46.2 % to the BEC variation amplitude with 28 % of MNDWI. This study provides a theoretical basis for building energy conservation from wetland park cooling perspectives.
