Simulation tests on windows for energy efficiency

ABSTRACT A window in a home and building refers to the opening in a wall. There are different types of window designs with appropriate glazing systems, which help to diminish building energy intake for warming and cooling and contribute to building a greener economy. This report accesses and discusses nine different glazed window types which are made of clear glass, colour-tinted glass, reflective glass and low emissivity (low-e) glass. These materials reduce the warming and cooling loads of buildings by regulating the amount of solar energy and conserving the heat, with some to a larger extent. The purpose of the project is to evaluate on the energy efficiency of the different types of glazing windows on a common high-rise residential building in Singapore. Nine types of glazing system were selected to test their energy efficiency and were simulated by using the simulation tool EnergyPlus. The results show that those with reflective and low emissivity glazing are the most energy efficient options among the selected windows, in relation to building energy consumption and economy.Bachelor of Engineering (Materials Engineering
