Through listing data of prime investment and year running cost for the air conditiouing systems with different types of cold source and combining the particular characteristics of theatre building analyzes and compares the economics and technique among three scheme.

With the development of the theatre building, more and more multifunctional and long-span spatial theatre building have been founded, which is comprised of the long-span auditorium, stage and supporting infrastructure.

Design of performance-based smoke management of large-space building;

The heating systems that are applicable in large-space buildings are introduced, and the characteristics of floor radiant heating system and gas-fired infrared radiant heating system that are applicable in large-space buildings are analyzed.

Zero equation model is applied in thermal environment simulation of large-space buildings.

Comparison of calculation models for smoke temperature in fire of large space building;

Numerical simulation and thermal comfort analysis of indoor air distribution in large space buildings;

Discussion on the construction of double spiral duct in large space buildings;

Analyses the parameters of fire temperature elevation at the top of large space buildings;

Water sprinkler effects on smoke layer in large space fire;

Measurements of indoor thermal environment and energy analyses of a large space in winter conditions;

Experimental study on efficiency of smoke exhaust in large space buildings;

Biochemical terror patterns in public large space buildings include firing to produce poisonous gas,exploding gas bomb to spread poisonous materials and artificial distributing poisonous materials directly.

With the increase of large space buildings,more and more energies are consumed.
