Water and Wastewater Systems in Highly Energy-Efficient, Environmentally Friendly Houses for 2013 Solar Decathlon China

Abstract

This paper discusses the design of water and wastewater systems in highly energy-effi'cient, environmentally friendly houses for 2013 Solar Decathlon China (SDC). Team XIAU's work "Sunny Inside" is taken as an example to discuss the design and installation of cold and hot water systems, grey water and rainwater collection systems, irrigation system and drainage system. Heat pump, solar water heater, low-pressure air atomization and membrane biological reactor are introduced. Other teams' new technologies on this issue are also being discussed.
