The standard of building energy conservation in Chongqing rises from 50% to 60%.

Thereafter, all energy saving projects shall reach the standard of over 65%. At present, more than 95% of buildings have not come up to the standard. However, new completed construction projects will not approved or some be fined, if not reaching the standard.

The use of glass curtain wall will be restricted. The extensive glass curtain walls, once led the tide of urban building styles, now has been definitely restricted in Chongqing City.
