Today's Low Carbon Series is about saving energy at work. Beijing is seeing an increasing number of office buildings, as more businesses set up their headquarters in the capital city. Low carbon design is also gradually becoming a fixture in the new commercial buildings.

In tomorrow's low-carbon series, we'll look at how the corporate sector contributes to China's low-carbon targets.

When Nokia completed its new headquarters in Yizhuang, about twenty kilometers away from the city center, the staff were reluctant to use the building.

Now, the complaints are less frequent. Most employees like the new office.

Anna Wang, Accountant of Nokia China, said, "We are not as depressed as people who work in a place with little sunlight. You can enjoy the outside view through the large windows. Several days ago my colleagues all stared out the window to see the annular eclipse."

In fact, the special design enables 90 percent of the office area to enjoy natural sunlight.

The double glazing curtain wall adjusts temperature automatically. The indoor temperature will not be impacted by conditions outside.

Rapidly renewable materials and products are widely used in the building.

"This is the only escalator in the building...more chances to exercise."

Walking is encouraged in the building. Pedometers are available for the staff. Strolling around in such a big building has two purposes: working, and exercising.

49 different shuttle buses are provided for the staff, but a car park is still a necessity. Parking spaces are reserved only for low emission vehicles.

"The company encourages us to use small cars..." said Maggie Li, Business Development MGR., Nokia China.

The bright atrium is the best place for a tea break or simple meetings.

Tay Kimchuan, Head of Real Estate, Nokia China, said, "...Being green doesn't mean it has to be more expensive.."

With eco-designs, the building saves 20 percent in energy costs, compared to normal office buildings, and helps save the environment.
