为实现建筑领域“碳达峰”和“碳中和”宏伟目标，建筑围护结构的优化设计和可再生额能源就地利用至关重要。该书介绍了建筑窗体节能的国内外研究最新进展，提出一种集采光、遮阳隔热和太阳能热利用功能于一体的水流窗，并论述其实验测试、综合节能模拟结果等。本书详细介绍了水流窗的具体结构、实验测试系统构成及香港地区气候条件下的测试结果。在此基础上，建立水流窗的数值模型及程序，并通过实验数据成功验证，其后用于水流窗热工性能优化设计和全年节能效果分析。此外，本书结合ESP-r建筑能耗仿真模拟平台和Radiance光环境模拟软件对水流窗的建筑综合节能潜力进行预测。结果表明，水流窗在具有较高的冷负荷密度和热水需求的建筑中具有广泛的应用潜力，有助于建筑领域的“碳中和”目标实现。
