C-iD

What is C-iD?
C-iD stands for 'Circular Identity' and is a digital tool to create element passports. You can create a digital
construction file that is customizable and that you can consult anywhere. No more paper covers lying in an archive
in the office. The digital environment provides a dynamic way of working where you can always add information
about, for example, maintenance, replacements or repairs. This way you bundle information from the entire use
phase of the element per element. A QR code is linked to an element, building or site so that you can consult the
information on site.

Why C-iD?
In order to minimize the use of new raw materials and close cycles, it is necessary to reuse existing elements. Due
to a lack of information, it is now not always feasible to reuse elements on a large scale for technical or legal
reasons. To simplify future interventions and reuse, it is necessary to know where the element comes from, how it
can be disassembled, what maintenance has been carried out on it, ...
Materials and raw materials are processed into elements, which are then placed in buildings. Elements such as
windows, doors or technical installations will be maintained or reused more quickly one-on-one than in their
individual raw materials. That is why we work with element passports here.

How did C-iD come about?
C-iD is the output of the project 'Applying element passports in practice', with the support of Flanders Circular. C-iD
was developed by several workshops with an extensive sounding board group (architects, contractors, producers,
...) and test cases with large patrimony owners. The feedback from the sounding board group and a consultation
with OVAM resulted in an extensive package of parameters needed for a good element passport. The test cases
made it clear how clients use the passport, which parameters they fill in and how user-friendly it should be. All this
made C-iD as it is today.
