Beijing mall wins top US award

Malls used to be all about shopping, but as air quality becomes one of the top concerns globally, some of them have set out to make themselves urban retreats.

Beijing's Parkview Green, a complex that includes offices, a shopping mall, an art center and a hotel, was recently awarded the LEED Dynamic Plaque by the US Green Building Council, a nonprofit organization based in Washington which promotes sustainability in buildings.

This follows the LEED Platinum certification it earned in 2009.
