Abstract
- This study investigates the influence of window system configurations on the energy use/cost, access to daylight and view, visual comfort and environmental performance in a one-bed hospital patient room located in a temperate climate. The methodology combines dynamic energy simulations, visual comfort and daylight analysis in a life cycle assessment study of window systems, covering a wide range of environmental indicators. In this study, multi-criteria evaluation approach is used to analyse the different design alternatives. A graphical optimization method was elaborated to filter the solutions and select the most appropriate window design based on project objectives and architectural preferences. The results show that glazing with '0.30 < g-values≤0.50' and '0.50 < Tvis < 0.75' have lower energy use and/or cost, lower environmental impacts while maintaining sufficient daylight levels (sDA > 55%) and showing higher quality for visual comfort. These type of glazing allows for using bigger windows which leads to a higher percentage of the outside view. [ABSTRACT FROM AUTHOR]
