#Circular economy is entering the facade industry

The façade builder remains the owner of the facades, allowing him to take re-use into account during the design phase. The chances are that he will more often opt for replaceable constructions or products. VMRG (The Association of Metal Windows and Facade Industry Netherlands) points out that the industry sees the circular economy as the economic model to guarantee long-term prosperity, maximizing the reusability of products and raw materials and minimizing value destruction.

The first contract whereby the façade of a building remains the property of the façade builders was signed at the end of January for a pilot project at the Eneco EnergyCampus in Utrecht. The so-called Facade Identification System (FIS) is implemented in the project.

Identification system monitors window frames and doors.

'FIS makes it possible to make a façade element, such as a door frame or a door, identifiable throughout the life cycle and to link digital information to it', according to VMRG on the website. The trade association has developed the system in collaboration with SlimLabs, Root and Tagologic.

In 2016 TUDelft already carried out a trial with the lease of different types of façades. The university wanted to gain insight into the performances, the comfort provided, the costs and the ideal design. In short: the business case.

Scientists at TU Delft are developing a circular business model for building facades to enable sustainable buildings on a large scale. In the pilot project Facade Leasing, the researchers have made four façade panels, with which buildings can be preserved. For example, a façade system consists of an aluminum frame and must have a service life of 75 years. Furthermore, a facade element has been processed with PV cells, ventilation systems and LED lighting.

Sustainable lease concept

According to the scientists, the facade systems can indicate to building users, by newly developed technology, when they need to be replaced. This contributes to reducing maintenance costs.

With the lease concept of the façade elements, the producers remain the owner of the product and the materials. Building users pay a monthly fee to use the façade elements and the façades can be replaced with a new one after a while, after which the old façade will be recycled or reused by the producer.

In this way the project contributes to the circular economy, in which cycles of building materials are closed.

Circular building

Together with a consortium of companies, the scientists will install the façade systems on the EWI building of the Faculty of Electrical Engineering, Mathematics and Computer Science on the campus of TU Delft this month. "The test must give us insight into the costs and benefits of different types of façade", says Alexandra den Heijer of the Facade Leasing Project on behalf of the Faculty of Architecture at TU Delft, Bouwwereld.

This pilot project must show that the innovative façade systems can actually make buildings more sustainable and reduce the energy consumption of the built environment. With proven success, the researchers are looking for new opportunities to apply the lease concept.
