Solar Powered Sundial Building Is No Birds Nest

The International Solar Cities Initiative conference is in Dezhou, China next year, so they built a conference center with a giant sundial that has everything but the gnomon. Jetson Green tells us that the the 75,000 square meter (807,293 square feet) center includes exhibition centers, scientific research facilities, meeting and training facilities, and a hotel. It'll be a showcase of solar design, solar desalination, and, of course, about 50,000 square-feet of solar panels on the exterior.

An equatorial sundial in the Forbidden City, Beijing: The gnomon points true North and its angle with horizontal equals the local latitude.

The incredibly slow website notes:

Green ideas have been applied throughout the construction. The external structure of the building used only one percent of the steel used to construct the Bird's Nest. Advanced roof and wall insulation mean energy savings 30 percent higher than the national energy saving standard.

However I suspect that if Herzog and De Meuron had designed this it would have looked a bit better.

With advanced roof and wall insulation, the conference center is supposed to be about 30% more efficient than China's national standard. And, notwithstanding its size, renewable energy will power 95% of the center's energy needs.
