Fenlo-Green Building

Cradle-to-cradle design (C2C design) is a school of circular economy thought, which aims to realize the continuous recovery and reuse of materials in technical or biological systems. The design of the new city hall building in Fenlo incorporates the concept of circular economy, and recyclable materials are selected and used in subsequent stages.

The advantage of this design concept is that the material can be sold back to the manufacturer through the "buy and repurchase" program and eventually reused, thus recouping some of the initial investment. This can not only achieve long-term economic benefits, but also protect the environment and human health.

The establishment of Fenlo City Hall also had a ripple effect on the surrounding area; as a result, an old community factory nearby was renovated to join the dormitory area. In addition, 72 new houses in accordance with the C2C principle will be built next to the Fenluo City Hall.

The plant north facade of the building is composed of more than 100 plants and aims to improve the air quality outside the building.
