The Sino-Finnish Cooperation and Communication Centre, built by CSCEC, has recently been completed and officially opened. Nicknamed Nanjing's "Ice Cube," the complex showcases a blend of innovative design and green technologies, aligning with the growing trend toward low-carbon architecture.

Designed by a Finnish architect team, the project has a total floor area of approximately 210,000 square meters. It consists of four main components: The Sino-Finnish low-carbon ecology and smart city exhibition center, a featured convention and exhibition center, a high-end business hotel, a business office center, and specialty commercial spaces.

Inspired by the concept of an ice cube, the overall architectural composition resembles an icebreaker navigating the Baltic Sea, while three smaller buildings in front of the main structure evoke floating ice blocks, vividly expressing the project's low-carbon and environmentally friendly vision.

The project has achieved several breakthroughs in low-carbon technologies. The main building adopts a double-skin glass curtain wall system—a "breathing" façade in which the cavity between the two layers forms a natural ventilation channel. This design enables natural air circulation, providing ventilation in summer and insulation in winter, and reduces energy consumption by more than 30 percent compared with conventional curtain wall systems.

Another highlight is the use of three steel–timber hybrid structures. Timber structures offer excellent thermal insulation, shading and soundproofing performance, enabling ultra-low energy consumption throughout the building's lifecycle.

The stepped water landscape surrounding the complex reflects Finland's forest-and-lake scenery while incorporating elements of Nanjing's traditional waterside culture. Beyond its aesthetic appeal, the design also helps regulate the microclimate of the site.

As a model project for low-carbon development, the center also features advanced smart-building systems. Built around the concept of "smart exhibitions," the complex integrates building automation, intelligent lighting, and security monitoring systems to form a comprehensive digital management platform.

The hotel's hot-water system incorporates solar energy equipment to maximize the use of renewable energy. This innovation is expected to reduce carbon emissions by approximately 523 tons annually—equivalent to planting around 28,300 trees.
