Urban Heat Island Effect on Building Energy Consumption: ANN Method Application
The urban heat island (UHI) phenomenon denotes the higher temperatures observed within urban areas compared to their surrounding rural areas. The repercussions of the urban heat island are not only limited to the pedestrian discomfort but also influences buildings’ energy consumption. In this paper, Artificial Neural Network (ANN) based method is used to determine the urban temperature increase and quantify the UHI effect on the energy consumption of an office building in Montreal, Canada. It was found that the annual average urban heat island intensity for the study area is 2.6 ℃. Due to the UHI effect, the annual cooling energy consumption of the building in the study area increased by 18% (6.75 kWh/m2) while its heating energy reduced by 34% (5.21 kWh/m2). The total HVAC energy consumption of the building (cooling plus heating) on a yearly basis increased by 3% (1.54 kWh/m2). The result of this investigation shows the importance of considering the impact of UHI when engineers size cooling and heating equipment and the need for urban planners to introduce measures to mitigate the increases in urban temperature.
