ABSTRACT
Researches on energy conservation in building，especially in residential buildings，are urgent particularly in front of the world energy crisis．Today many countries have conducted thorough researches on this subject．Among the discussion and researches on various energy-efficiency methods，development on energy-saving building materials，new technics，new heat preservation windows and doors，and new energy etc．have received more attention．
Based on the property of climate of our country and taken into account the diversity and instability of climate influence factor，energy-saving design methods，aiming at the residential building in hot sununer and cold winter region and iciness winter region,were proposed in this paper．The aspects of layout of buildings，building shape and enclosure details were included in．It is to dream up energy saving and local colorful modern residential buildings．
This paper was unfolded from the importance of energy saying，review the research status in this field，deciding the research aspect．Then energy saving method for buildings in hot summer and cold winter region was proposed，including integer design and sole design．The energy saving method for buildings in iciness region was proposed in turn．At last，energy saving modification for old buildings was also taken into account．
Keywords：energy conservation in architecrure；hot summer and cold winter region； freezing cold winter region； residential buildings；architectural design
