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.

本研究调查了位于温带气候的单床医院病房中窗户系统配置对能源使用/成本、获得日光和视野、视觉舒适度和环境性能的影响。该方法在窗户系统的生命周期评估研究中结合了动态能量模拟、视觉舒适度和日光分析，涵盖了广泛的环境指标。在这项研究中，多标准评估方法用于分析不同的设计方案。阐述了一种图形优化方法来过滤解决方案，并根据项目目标和建筑偏好选择最合适的窗口设计。结果表明，“0.30 < g-values≤0.50”和“0.50 < Tvis < 0.75”的玻璃具有较低的能源使用和/或成本，降低环境影响，同时保持充足的日光水平 (sDA > 55%) 并显示更高质量的视觉舒适度。这些类型的玻璃窗允许使用更大的窗户，从而获得更高比例的外部视野。
