ANALYSIS OF ENERGY SAVING DESIGN OF SOLAR BUILDING -Take Tongji University solar decathlon works for example

摘要

From 2010 to 2012, Tongji University has constructed three solar houses to take part in Solar Decathlon and gained International prize for three years. This paper analyzed the architectural style and energy utilization of "Bamboo House", "Y container", "Eco-House". And then described original ecology and energy-saving technology applied in these solar houses. Authors have provided some beneficial advises in material collection, hydroelectricity, natural ventilation, and effective energy utilization. The considerable development trend of solar building has inspired architects to pursue "Zero Energy" solar energy technology.
