Early prototype

A TRL is a measure to indicate the matureness of a developing technology. When an innovative idea is discovered it is often not directly suitable for application. Usually such novel idea is subjected to further experimentation, testing and prototyping before it can be implemented. The image below shows how to read TRL’s to categorise the innovative ideas.

A multidisciplinary team within the Faculty of Architecture is the first to operationalize a Product-Service System (PSS) for building facades. A PSS delivers performance instead of products with positive financial, environmental and social consequences.


With a practical, design-driven research approach the team investigates the challenges of such a PSS. These involve creating a business case for all stakeholders involved with the right distribution of benefits, responsibilities and risks.


A consortium of over 15 partner companies, representing suppliers and clients in the construction industry, are working on a pilot project at the TU Delft campus. The first circular, multi-functional façade will be installed in June 2016.
