In the region abundant in solar energy and a case study in lanzhou city,apartment design system with passive solar heating was put forward for zero-heating energy and constructed zero-heating energy design process.

Dynamic calculation method of heating energy consumption on building outside walls and roofs;

Dynamic calculation method of heating energy consumption of building outside windows;

But among them, the sum of energy consumed for heating of residential building is the biggest.

And the energy consumption of the workshop,which is constructed by vinyl covered steel plate material,is analyzed.

CFD simulation software is used to simulate the temperature field in this paper,the envelope internal surface temperature and heating energy consumption of the workshop with traditional warm-air heating system.
