Heat Transfer in the Universal Form of High-rise Buildings in Various Climate Zones

Abstract

The design of form and façade in high-rise buildings impacts energy consumption, especially in heating and cooling. Applying passive design techniques in building forms is a crucial step to decrease energy loads for heating and cooling in the design phase. This paper aims to show the energy required for and mechanism of heat transfer in universal forms of high-rise buildings (Extruder, Rotor, and Twister) in various climate zones. This article studies the heat gains and losses accumulated in the façade (including infiltration) based on the building's forms and the climate where they are located. The simulation is conducted using Sefaira®. Energy consumption of thermal conditioning as the impact of heat transfer will also be discussed. The results show that climate plays a role in determining the heating and cooling performances of high-rise buildings with universal forms. The Rotor model performs the best for heating and cooling in all climate zones, while the Extruder model is most suitable in cold climates.
