US practice Studio Shift has unveiled the designs for a sports centre in Miyi County, China.
The 3,000-seat multipurpose venue features a 200-seat tennis court, a swimming pool, and several badminton and table tennis courts, according to ecofriend.org.
The design's sustainable concepts include rainwater collection for reuse, and a glazing system for windows to control glare and heat gain.
A range of thin-film photovoltaic technologies are expected to be used for the roof cladding.
The sports centre is expected to be complete by 2013.
