Project Case | The World's First Ultra-Scale Zero-Carbon Building: Teld Headquarters

CCTV News recently reported: The world's first ultra-scale "zero-carbon building" is expected to be officially put into use soon in Qingdao, Shandong. It is called "zero-carbon" because photovoltaic glass is installed on the east, south, and west sides of the building's glass curtain wall, which can supply green electricity. It is called "ultra-scale" ultra-scale because, in addition to photovoltaic power generation, the building also achieves 100% green energy replacement through cascade energy storage batteries and new energy vehicle discharging.

 

The Qingdao Teld Zero-Carbon Building project is a major project constructed by Teld New Energy Co., Ltd. in Beizhai Street, Laoshan District, Qingdao. The project aims to create a benchmark and demonstration base for China's carbon neutrality and new power systems, integrating BIPV (Building Integrated Photovoltaics), distributed energy storage, smart parking, automatic charging, vehicle-grid interaction, smart microgrids, off-peak energy storage, digital platforms, multi-station integration, and ten distinctive zero-carbon building technologies. Once completed, it will become the nation's first uniquely energy-featured zero-carbon smart building.

 

 

The "power generation cloak" — the photovoltaic curtain wall system jointly created by Jianghe Curtain Wall and Jianghe Photovoltaic for the Teld Headquarters building — redefines the green value of super high-rise buildings with BIPV technology, becoming a solid support for this city's energy innovation.

△ Teld Headquarters Building

 

The Teld Headquarters building is 116 meters tall with 23 floors above ground, featuring a simple and grand appearance. At first glance, it seems hard to distinguish it from other office buildings, but its secret is actually hidden within the curtain wall.

 

Using BIPV (Building Integrated Photovoltaics) technology, the photovoltaic curtain wall is perfectly integrated with the building, giving the curtain wall the ability to absorb solar energy and convert it into electricity, as if the building is wearing a "power generation cloak." The electricity generated is not only used for the building's daily office operations but also provides charging services for new energy vehicles.

 

At the same time, the building transforms from a simple energy-consuming entity into a structure with power generation capabilities, achieving harmonious coexistence between building functions and energy production, while significantly improving economic and environmental benefits.

How does this building, like a "micro power station," generate electricity?

 

Under the joint design of Jianghe Curtain Wall and Jianghe Photovoltaic, BIPV technology shines brilliantly. The building's curtain wall is closely combined with photovoltaic modules, making the building an excellent carrier for solar power generation.

 

On the south, east, and west facades of the building, in the opaque areas between floors, designers cleverly replaced traditional glass curtain walls with photovoltaic curtain walls. These photovoltaic curtain walls use photovoltaic modules with high photoelectric conversion efficiency to ensure stable power generation under various lighting conditions.

 

△ Photovoltaic curtain wall at the building's crown

 

On the tower crown and canopy of the podium, which receive direct sunlight and have less shading, higher-efficiency monocrystalline silicon photovoltaic modules are used, greatly increasing power generation.

 

In this way, the building's curtain wall can continuously convert absorbed solar energy into electricity, thus creating a "micro power station."

△ Coordinated and unified facade photovoltaic curtain wall and translucent curtain wall

 

To avoid color differences between the photovoltaic curtain wall and the translucent curtain wall glass, designers used a heat-reflective coating process. By precisely controlling the glass reflectivity, they achieved color coordination and unity of the curtain wall, while giving the building a modern technological and fashionable atmosphere.

 

The tower crown roof uses black TP6+PVB+monocrystalline silicon cells+PVB+TP6 double-glass photovoltaic modules, ensuring building safety while highlighting a design concept that balances fashion and practicality.

 

△ Tower crown monocrystalline silicon photovoltaic system

 

The black monocrystalline silicon modules on the south facade podium canopy echo the tower crown. The tilt angle of the modules is carefully designed to ensure smooth drainage and effectively reduce dust accumulation, which affects appearance and power generation efficiency.

 

△ Podium canopy photovoltaic system

 

The rolled glass used on the outside of the photovoltaic modules effectively avoids mirror-like reflection light pollution, reflecting a high degree of environmental protection awareness and responsibility.

△ Installation of the building facade photovoltaic curtain wall

 

During the curtain wall construction process, facing the complex installation challenges of overlapping traditional curtain walls and photovoltaic curtain walls on the facade, the Jianghe Curtain Wall team demonstrated professional strength and craftsmanship.
 

 

From the design of the photovoltaic module back wiring to the clever use of aluminum alloy beams combined with DC cable trays, every step embodies the team's wisdom and effort.

 

At the same time, the team fully considered coordination and waterproofing issues between the photovoltaic panels and the building's main structure during installation, efficiently and with high quality completing the construction tasks, ensuring the photovoltaic curtain wall is both beautiful and safe, laying a solid foundation for the zero-carbon smart construction of the Teld Headquarters building.

△ Building photovoltaic system schematic

 

It is worth mentioning that Jianghe Photovoltaic custom-designed the photovoltaic system for the Teld Headquarters, adopting an innovative photovoltaic-storage-direct-current-flexible distribution system.

 

This solution allows the electricity generated by the photovoltaic system to directly power DC charging piles, DC lighting, and other equipment, reducing energy conversion steps and improving energy utilization efficiency.

 

This innovative measure not only provides a more efficient and environmentally friendly energy solution for the building but also offers new ideas and inspiration for future building energy management.

The zero-carbon intelligent construction achievements of the Teld headquarters building not only provide green and sustainable energy solutions for itself but also greatly reduce carbon dioxide emissions, making a positive contribution to urban energy transition and sustainable development, becoming a new model leading zero-carbon buildings.

 

Letting buildings generate their own electricity is just the beginning of the green revolution.

 

As a pioneer in energy innovation, the "zero-carbon intelligent" building jointly created by Teld, Jianghe Curtain Wall, and Jianghe Photovoltaic also paints a hopeful future for us:

 

When more buildings are clad in "power-generating attire," we will eventually witness every wall becoming an energy field and every building a charging station.
