The Technology of Applying Renewable Energy in the New Countryside Ecotype HousesAbstract: Due to lack of scientific design and appropriate technology guidance, countryside houses in our country are universally in poor thermal environment, lag behind in energy production and application, and obvious on energy waste, while the energy consumption on countryside houses is increasing. We should on one hand advocate energy saving, and on the other hand search for renewable energy like solar energy, geothermal energy, wind energy and biologic energy. This article gives analysis on applying solar energy and biogas energy technologies and puts forward some economical and appropriate technological measures about renewable energy application as technology support and theory guidance for constructing new countryside ecotype houses.Key words: New countryside construction; ecotype houses; solar energy; biogas energy1 IntroductionAs the continuous development of countryside economy, it has been country people’s urgent necessary to improve houses functions and living environment, and constructing economical and beautiful green energy-saving houses. The fact is due to lacking of scientific design and appropriate technology guidance, the countryside houses in our country have been in irregular and disorder state for a long time, and the most-seen is the traditional extensive model. In recently year, there’s an obvious trend of increasing energy consumption in new countryside houses construction. It has become an unavoidable strategic topic for new countryside construction to construct a safe, healthy and comfortable countryside houses environment while no obvious energy consumption noted.Tsinghua University Construction Energy Saving Resear...
