Efficiency Analysis on Civil Building Heating Source in LHASA

This paper made a synthetic comparison in the initial investment and operating cost aspect for the civil building of envelope heat preservation,passive solar energy technology and three possible kinds of heating source systems——solar energy hot water,coal-burning center heating and electricity-regeneration boiler in Lhasa.The results show that civil building heating in Lhasa should be based on the envelope heat preservation and the passive solar energy utility,and the solar energy hotwater heat source presents better efficiency.
