Abstract: High-rise buildings typically have a much higher energy demand than low-rise buildings. With the increasing number of high-rise buildings, more research should be carried out to minimise their consumption. High-rise buildings affect the solar conditions and wind environment of the surrounding areas, positively and negatively affecting the site-specific circumstances. Previous works focused on the urban morphology effect, not many works assessed the influence on high-rise building energy performance or the influence of neighbouring structures on high-rise building energy performance. To address this gap, the present work will analyse the impact of building locations and neighbouring buildings on a 12-storey residential building’s performance undertaking parametric modelling by using Building Energy Simulation (BES) - IESVE. Multiple high-rise buildings with narrow spacing were observed to have the largest impact on the central building’s energy performance. Overall, the results indicate that the design and layout are important issues to consider for high-rise buildings as they can influence the energy use up to 14.35% when eight double-height buildings surrounded the central building with 15m spacing. The correlation between heating load and solar was 80%.
