The book introduces the development of advanced glazing, energy-saving oriented window designs and the related numerical models, and brought forward a water-flow window that combines the functions of daylighting, thermal insulation and solar thermal utilization. The numerical model and program of water-flow window were developed and successfully validated with experimental data. The program was used to calculate the annual thermal and energy performance and to analyze the influences of design parameters. Additionally, the comprehensive energy saving potential was assessed with the combination of ESP-r simulation platform and Radiance software. The energy consumption reduction and the pay-back period of water-flow window were estimated. Results demonstrated that water-flow window, as an innovative renewable energy utilization technology, has an extensive application potential in buildings with high density cooling load and constant demand of hot water.
This book can be used as a reference book for architects, engineers and scholars in the field of building technology and energy conservation. It is also suitable for postgraduate students to learn engineering research methods.
