ZHA to build Shanghai’s ‘greenest building’

The new headquarters belongs to the China Energy Conservation and Environmental Protection Group.

Zaha Hadid Architects has been selected to build the new Shanghai headquarters of the China Energy Conservation and Environmental Protection Group (CECEP), one of China’s leading companies initiating and funding projects with a focus on renewable energy technology.

In line with CECEP’s principles, the new headquarters was designed to be the ‘greenest’ building in Shanghai with sustainability embedded into every aspect of its design and construction to achieve more than 90 credits in China’s exacting Three Star Green Building Rating system – the highest score for any building in Shanghai.

Located next to the Yangpu Bridge on the Huangpu River, the design for the 218,000-square-metre headquarters responds to its riverfront site and is defined by the history and dynamism of Shanghai.

A mixed-use urban campus of three office towers, shopping, dining and leisure facilities linked together by a park that connects directly with the city, the headquarters creates vital new public spaces for its staff and neighbouring communities to enjoy the natural world.

Incorporating rainwater harvesting to irrigate expansive green spaces and landscaping in a biophilic design that enhances indoor-outdoor connectivity, the design also minimises cooling demand through optimised external shading.

With Shanghai’s significant temperature differences between day and night, each building’s integrated thermal mass also provides reductions in both heating and cooling consumption. Extensive use of locally-produced, prefabricated components will reduce the project’s embodied carbon and also support the local economy while procurement will prioritise the use of recycled materials.

Photovoltaics located at roof level and within the façades are connected to battery storage and a micro-grid to provide on-site energy production that will reduce energy consumption by 25 percent.

The new headquarters will also use thermal ice storage for cooling: ice generated by chillers at night using off peak electricity is stored in thermal tanks then used for cooling during the day to significantly reduce peak daytime electrical consumption when the cooling load is at its highest.

The building management system will continually monitor the interior environment and automatically react to changes in internal conditions such as variations in temperature, air quality, natural daylight, or number of occupants. To reduce energy consumption and prolong their lifespan, these intelligent systems will also collate data to predict and optimise energy usage.

The new headquarters will use 5G network capability to operate intelligent management and biometric security systems that will eliminate contact with communal surfaces by staff and visitors.
