The BMW-Brilliance Automotive joint venture will open its most sustainable dealership in the world next month in Beijing.

Environmentally-friendly, renewable energy sources such as wind power, solar and geothermal energy are being used at the huge 22,000 sq m Beijing Xingdebao site.

Wind turbines and solar panels on the 1,500 sq m roof supply 3% of the dealership’s annual energy requirements and an underground central air-conditioning system fitted with heat pumps use the geothermal energy found in groundwater and topsoil for heating and cooling purposes.

The creative use of overhead lighting and glass walls means that more than 75% of the office area is illuminated by natural light, reducing power requirements.

Daniel Kirchert, senior vice president, sales and marketing, of BMW Brilliance Automotive added: “Thanks to an efficient water treatment system, more than 80% of the water used for washing cars can be recovered. Combined with rainwater collection and other water-saving solutions, this reduces water consumption at the dealership by 50%.”

In overall terms, Beijing Xingdebao uses 26% less power than conventional commercial buildings in China.
