Based on the climatic conditions and residential energy consumption in regions with hot summers and cold winters

three principles of building energy efficiency were used to explain the technical system and technical solutions for low energy consumption residence. To improve the energy efficiency in residences

and to produce more comfort as well

we should adjust sunlight

improve ventilation

reasonably insulate houses

make full use of natural energy sources

and choose high COP(Coefficient of Performance) equipments. Making reasonable use of local resources while planning and designing a residence is the key to low energy consumption. The solution given in this paper provides references for development of low energy consumption residences in regions of this type.
