BIG to Design Shenzhen International Energy Mansion

Copenhagen-based BIG, in collaboration with ARUP and Transsolar, was awarded the first prize in the international competition to design Shenzhen International Energy Mansion, the regional headquarters for the Shenzhen Energy Company.

Located in the center of Shenzhen, China the 96,000 square meter project will be integrated with the surrounding environment and designed to withstand the tropical climate of the city. BIG’s winning proposal was selected by the jury experts from Shenzhen Municipal Planning Bureau chaired by Alejandro Zaera-Polo and client representatives.

The headquarters rises 200 meters creating a new landmark visible from the highway in the cultural, political and business center of Shenzhen. BIG envisions combining a practical and efficient floor plan layout with a sustainable façade that both, passively and actively reduce the energy consumption of the building. The façade is conceived as a folded skin that shades the office complex from direct sunlight and integrates solar thermal panels, reducing the overall energy consumption of the building.

Here’s more detailed information from BIG explaining the project:

Modern Vernacular

We are proposing a tower based on an efficient and well-proven floor plan, enclosed in a skin specifically modified and optimized for the local climate. We propose to enhance the sustainable performance of the building drastically by only focusing on its envelope, the façade.

Design Evolution

The origami like structure of a paper lamp is designed inspired by the ingenuity observed in naturally evolved plants.

The traditional stepped landscapes of rice paddies have evolved by man adapting the natural landscape to meet their needs for inhabitation and food production.

Today the skyscraper needs to evolve into a new sustainable species. It must retain its highly evolved qualities such as flexibility, daylight, view, density and general usability, while evolving new and untested attributes such as ways of combining maximum daylight exposure with minimal sunshine exposure or integrated ways of limiting the need for cooling. 

We propose to make the Shenzhen Energy Mansion the first specimen of a new species of office buildings that exploit the buildings interface with the external elements - sun, daylight, air humidity, wind – as a source to create a maximum comfort and quality inside.

The Shenzhen Energy Mansion will appear as a subtle mutation of the classic skyscraper – a natural evolution rather than a desperate revolution.

Curtain wall

1. The traditional curtain wall glass façade has a low insulation level and leaves the offices overheated by the direct sunlight. This results in excessive energy consumption for air conditioning as well as the need for heavy glass coating that makes the view seem permanently dull and gray.
2. By folding the façade in an origami like structure we achieve a structure with closed and open parts. The closed parts are providing a high-insulation façade, while blocking the direct sunlight. On the outside the closed parts are fitted with solar thermal heat panels that are powering the air conditioning and providing dehumidification for the working spaces.
3. The folded wall provides a free view through clear glass in one direction, and creates condition of plenty of diffused daylight by reflecting the direct sun between the interior panels.
4. Even when the sun comes directly from east or west, the main part of the solar rays are reflected off the glass due to the flat angle on the window. The reflected rays increase the efficiency of the solar thermal energy panels. The combination of minimal passive solar heating as well as active solar panels will reduce the building energy consumption with more than 60%.
