Ennead Architects' Thomas Wong reveals Shanghai Planetarium plans

Once complete in 2018, the 38,000sq m (409,000sq ft) development – a part of the Shanghai Science and Technology Museum in the city’s new Linglang district – will explore the mysteries of space, celebrate the history of Chinese astronomy and reflect the future ambitions of China’s space exploration programme.

Speaking in the latest issue of CLADmag, Thomas Wong – design partner at New York-based Ennead Architects, who are overseeing the project – explained how the distinctive design is inspired by the concept of orbital motion and the continuum of time and space.

“Each element acts as an astronomical instrument and has a specific interface with how people experience an astronomical idea,” he said. “We looked at planetaria all over the world, of all eras, and were influenced by many ancient structures including the Aztec pyramids at Teotihuacan, the Pyramids at Giza, Stonehenge and the Temple of Heaven in Beijing. They were all very inspirational in terms of the power they deliver to a culture through built form.”

The structure will feature an oculus, designed so visitors can track a circle of sunlight on the ground “like a giant sundial”, and an inverted dome which is designed so “visitors are confronted solely and entirely with the day or night sky.”

“We want the building to feel quite abstract,” said Wong. “Inside we imagine a lot of white surfaces and a stark contrast between bright illumination and darker areas so one can sense the effect of sunlight.”

Reflecting on the biggest challenges facing the project, Wong said: “China is still in a relatively young era of construction technology and getting the best expertise and talent from the right people needed to execute this is a huge challenge. However, the leisure market here is growing very rapidly. The growth of museums in particular is really impressive. Part of our goal going to Asia is to bring some of that expertise to the region.”

Ennead are working with the Shanghai Institute of Architectural Design and Research (SIADR) in the design development stage to create “a landmark for the district and Shanghai”.

Wong promoted the project’s environmental credentials, revealing Ennead are targeting both LEED accreditation and a China 3-star rating for the planetarium.

“Sustainability and energy use have become acute issues in China because of the poor air quality from industrialisation,” he said.

“To counter this, we’re integrating a whole series of sustainable features, including a geothermal heat pump system for the planetarium.

"The project will also filter outside air and storm water to return it back to the environment cleaner than when it arrived, and we’re using healthy, low VOC materials and green roofs to reduce energy use," he added.

“The power of architecture to not only affect what people see but also influence how they live and work.”
