Abstract

The focus of this study is to determine the energy-saving potentials while adopting appropriate and efficient building form during the design stage of high-rise office building. This is to enhance and strengthen the decision-making on adoption of efficient form in high-rise buildings towards policy making on mitigation and resilience to climate change action for sustainable cities in Nigeria. The study derived the effect of cylindrical and rectangular building shapes on the cooling energy demand of a modeled high-rise office building in Lagos, a coastal city in Nigeria.  Comparison was performed with the simulation method using Autodesk Revit 2020, Green Building Studio and Insight 360 software. Window-wall ratios of 60% was used as a baseline comparison. Percentages of energy expended on space cooling, lighting, and other activities within the modeled building were determined. Result shows that cooling energy demand was lower in cylindrical-shaped high-rise base case building with a value of 19.79 (MJ/m²/year). A 4.57% reduction in the total amount of energy consumed annually was obtained in cylindrical-shaped building. The paper concludes that cylindrical-shaped building possesses a higher cooling energy saving potential than rectangular-shaped building. Consequently, cylindrical building form should be adopted for new designs of high-rise buildings to save cooling energy demand within the warm humid climate region of Lagos, Nigeria
