主　　题：residential building space organization heating energy consumption energy saving design 

摘      要：The heating load simulation models of the residential buildings in Lhasa are established for enhancing the space organization’s adaptability to climate and radiation and improving its energy saving *** space organization items a e analyzed for both the existing buildings without insulation and new buildings with good *** items include orientation design,south a d north balcony design,the north and south partition wall’s position design,storey height design and window-wall ratio *** results show that orientation is the key design element for energy saving design,and adverse orientation can obviouslyincrease heating energy consumption;south and north balconies can reduce winter heating energy consumption;partition walls move to the north,which means that the south room’s big depth design leads to less heating energy consumption,but the effect is not inconspicuous;smaier storey height results in less heating *** the existing buildings,the window-wall ratio of south side has a balance point for energy saving design in the calculation *** the new buildings with good insulation,enlarging the south window-wal ratio can continuously reduce heating energy consumption,but the energy saving rate between models gets *** heating energy consumption comparison study between the common model and optimal space design model demonstrates that the energy saving design can significantly reduce heating energy consumption
