FAÇADE TYPOLOGY DEVELOPMENT FOR ENERGY-EFFICIENT AND COMFORTABLE HIGH-RISE OFFICE BUILDINGS

Abstract

This research aims to improve the design of the building envelope structure for highrise office buildings in temperate climates. The study looked at different factors in the façade geometry design, for instance, window orientation, window-to-wall ratio, shading systems, and the level of façade perforation, to identify which parameters have the greatest impact on comfort and energy efficiency. Simulations were carried out on different building orientations, including east, west, south, south-east, and south-west. Further simulations were conducted on the enhanced envelope to investigate the potential of natural summer ventilation strategies by experimenting with various summer natural ventilation methods on the building-specific folded envelope design to reduce energy consumption for cooling and mechanical ventilation and improve the health and comfort of occupants. The IDA ICE 4.8 complex dynamic building energy simulation program was used for thermal and lighting modelling and for building physics calculations.
