This project is a follow-up to the international action COST CA21103
Implementation of Circular Economy in the Built Environment (
CircularB), which aims to develop an integrated approach to the
implementation and assessment of circular economy principles and
strategies in the construction industry with a focus on buildings.
A key prerequisite for the implementation of circular economy
principles in the building sector is the effort to maximise the use of
construction and demolition waste, which is however limited by the
low demand for secondary raw materials. The reason for this is the
variable and difficult to predict availability of these raw materials at
the place and time of planned construction, and the variability of their
technical characteristics.
The aim of the proposed project is to develop an online tool for the
processing of demolition audits and a national deconstruction
database linked to it, following the COST CircularB action. The
developed software will guide the user through the demolition audit
process and help the user to process and publish basic information
about the planned deconstruction. This information on the projected
availability of secondary materials at a given site will allow a forecast
of the supply of secondary materials that can be saved to replace
primary materials in new construction projects.
In addition, the software will evaluate planned demolition measures
in terms of circular economy indicators and provide feedback to the
user on how to reduce potential environmental impacts associated
with the end-of-life of construction and demolition waste. The
possibility of extracting at least part of the necessary information from
Building Information Models (BIM) will also be explored to support the
quick and easy implementation of demolition audits.
The developed tool will be tested and piloted during the project on
real deconstruction cases with representatives of future users, and
will be modified and tuned based on their feedback.
