报告内容摘要
A multifunctional material system is designed for the envelope of residential and commercial buildings with high performance with regard to energy efficiency and environmental sustainability. It contains a photovoltaic layer deposited on a thermoelectric layer which is then bonded to a plastic lumber substrate through an interlayer with graded properties containing water tubes. The first two layers convert both photoelectric and thermoelectric portions of solar energy into electricity. The substrate provides mechanical support and heat insulation for the building skin. The functionally graded interlayer reduces the thermal stress across the interface and controls the service temperatures of the other two layers by water flow through the tubes. The heated water is used by a hot water supply system. This work embraces energy harvesting through emerging solar materials, optimum utilization of recycled materials, and integration of hybrid solar panels, autonomous water heating systems, and insulating panel. As the first step towards understanding and optimizing the system, Green’s functions of specific functionally graded materials for thermal conduction and elastic problems are introduced, respectively. A big picture of this work will be introduced.
