abstract = {Preserving the natural environment puts growing pressure on
the built environment. In this regard transforming the
linear economy into a circular economy (CE) appears to be a
promising opportunity to reduce environmental impact and
resource depletion. As the construction industry is the most
resource-intensive industry, with millions of tons of raw
materials and waste produced each year, CE offers
alternative strategies to the current linear economy.
However, the transition towards a CE requires more knowledge
and information, especially about mineral material, their
waste and energy streams, as they have the highest shares of
consumed resources. Since a building is a conglomerate of
building products where material streams come together, the
entire life span of each product needs to be considered. In
this regard, building planners have a strategic position in
implementing circularity aspects and managing information
flow within the design process of a building. By selecting
recycled or reused products and designing demountable
connections, planners have a substantial impact on the
future material flow. On the one hand, planners are
confronted with an increasing amount of information about
products and how they should be constructed. On the other
hand, they lack experience and knowledge in implementing
circularity into practice. Besides, essential information
about products gets lost during a lifecycle of a building.
Especially during the design and construction phase,
information errors or their absence cause misleading
communication between stakeholders. Consequently, a lack of
data leads to a higher workload and lower quality of
material flows. Therefore, the description of essential
qualitative and quantitative information requirements during
the entire design process and predefined information
exchange points are essential for closing material flow
circles. Only if all relevant product information is
defined, documented and exchanged material streams can be
managed transparently, efficiently and more circularly.
Especially during the design phase, physical properties,
judicial and organizational information regarding
circularity aspects become important as they influence the
product selection and construction process. For example, by
knowing the key information about a product’s performance
in regard to circularity, planners can estimate the
environmental impact of potential decisions. The working
process can be influenced and the design process steered by
delivering the correct information about a product or design
task at a specific time. An integral Information Delivery
Model can distribute all relevant information about, for
example, building products and construction methods to
planners and their collaborators. The model has the
potential to document and deliver information, hence
guaranteeing a successful work, information and material
flow.6 First, relevant information such as product
properties and judicial and organizational data that
influence a circular material flow are de- fined based on a
literature review. Furthermore, all tasks during a circular
design process, the involved stakeholders, and the
information that needs to be exchanged are defined based on
case study research and literature review. Based on this,
the following scenarios for a circular design process are
presented:1) building with reused products, 2) building with
recycled products, 3) preparing products for reuse. Finally,
all relevant information and design tasks that follow
circularity principles are implemented in a model selected
for its compatibility with digital tools. This dissertation
aims to link information about mineral building products
regarding circular material flows to the design process of
buildings in a coherent information flow model. The goal is
to reliably deliver guidelines and standards for the use of
circular mineral building products and to provide a model
that enables the exchange, documentation and management of a
circular design process with the ability to be implemented
into a digital tool. This can decrease the use of natural
resources, reduce emissions during production and close
material flows. The model developed in this research offers
a basis for future implementation into BIM as a holistic and
collaborative working method that enables a circular design
process.},
