Energy and daylighting performances of highly glazed buildings

Abstract

Glazed façades create indoor environment more attractive and pleasant but also let high solar and thermal gains in the buildings that lead to energy inefficiency. Hence, more attention needs to be given to the glazed component to improve the buildings’ energy performance and indoor visual comfort. This study aims to provide insightful on the suitable selection of the glazed components for the office buildings. In this study, a number of simulations were performed, using EnergyPlus, for the office rooms with one and two exposure wall(s) in two different climates. Results were analysed and presented in terms of the energy demands for heating, cooling, fans and lightings and daylighting performance considering useful daylight illuminance (UDI) and discomfort glare.
