Analysis of effective parameters of building’s glazing on energy savings and carbon emission mitigation prospective

Abstract

The optimal window-to-wall-ratio of the glazing systems and the wall thickness of the building will help reduce energy consumption in the buildings. The current work explores the spectral characteristics of clear, tinted (Tinted Green & Tinted Bronze), and reflective (Reflective Bronze) glasses. Solar-optical properties of different double and triple glazing systems formed with the aforementioned glass samples using experimentally measured data. The laterite buildings modelled with three double-glazing configurations and three triple-glazing configurations at five different window-wall-ratios (20%, 40%, 60%, 80%, and 100%) have been studied for the solar heat gains, thermal loads, and daylight ingress. The model building with 0.229 m thick laterite wall and 40% TBRGW glazing had reported an annual cooling cost savings of $32.02 and carbon emission mitigation of 308.4 kg-CO2/year compared to 0.076 m thick laterite wall. The average daylight factor simulation results had concluded the adequate daylight inflow in the building interiors.
