(BEIJING, November 26) -- The newly delivered National Indoor Stadium is to be one of the main competition venues of the Beijing 2008 Olympic Games. Next year, the National Indoor Stadium will hold the Olympic Artistic Gymnastics, Trampoline, and Handball competitions and the Paralympic Wheelchair Basketball competition.

The stadium takes full advantage of renewable energy resources through a water source heat pump system. The project has five water source heat pumps that will be used during the summer season to disperse heat in the spectator area during competitions.

In the winter the water source heat pumps will provide heating during major competitions and provide everyday heating and water heating for the stadium.

To meet summer air conditioning demands and with consideration to the venue's post-Games functions, the stadium takes advantage of natural ventilations and natural lighting. Both athletes and spectators can enjoy a comfortable indoor environment.

In addition, the public area of the stadium uses water-permeable material to allow rainwater to seep into the ground. And rainwater collected on the rooftop will also be reused.
