As a specialist planner, we are guided by the multifaceted nature of circular building principles, building in the existing, working with what is already there, and expanding with new construction for the future reuse and further use of buildings and their components. We partner and advise on projects and competitions as well as promote research and education. We are constantly expanding our network in sustainable building.

Specialist Planning

We support you in the planning, bidding and implementation of a circular and climate-friendly building, in renovation as well as in new construction. Together we define the strategy and the framework conditions, be it financial, legal, normative or ecological. For your building project, we look for suitable components and ensure that they are given a second life in your project.

Building Screening

Our building screening provides a professional basis for the targeted reuse of building components. In a two-stage assessment process, we record and evaluate all relevant components of your building.
Based on an inspection, we first compile a list of components with an assessment of their potential. This is supplemented by a reuse concept for the most promising components.
In a second phase, an in-depth assessment of the reuse potential of selected components is carried out. For this purpose, precise data is collected and recorded in a detailed component catalogue. We provide you with the catalogue via Planular®, the planning software for reuse.

This enables us to then assist you in planning and implementing further steps, from component brokerage and coordinated removal to reinstallation in new projects.

We look forward to receiving your enquiry via: screening@zirkular.net

Competition & Commissioned Study

We understand the perspectives of both the client and the competition participants. We support clients in the planning of circular and climate-friendly competitions by providing catalogs of components, target specifications and jury participation. We accompany architectural offices in partnership as a team and integrate the principles of the circular economy in their competition entry.

Research & Teaching

Converting previous construction processes to the circular economy brings new questions and requires specific knowledge. We participate in solution-oriented research projects and are involved in teaching. We offer internships and train component hunters. In close exchange with authorities and associations, we help shape the future of the circular construction industry.

Planular®

The planning tool Planular® assists users in the process of reusing building components that become obsolete due to demolition or renovation and are suitable for another life cycle. The screening and management tool is used to catalog components in donor buildings and to assess their reuse potential. On the other hand, users can create receiving buildings for follow-up uses, manage supply and demand of components (matching), and use project monitoring to track, for exmaple, emissions savings. This platform ensures consistent and real-time data for all stakeholders involved and reliably reflects up-to-date information of donor buildings, building components, storage locations and receiving buildings.

reMATERIAL®

reMATERIAL, ist der Bauteilshop von Zirkular. Die Plattform ist seit Anfang 2026 online und dient als Marktplatz für ausschliesslich hochwertige, bereits ausgebaute und eingelagerte Re-Use-Bauteile. Ausgewählte Produkte werden direkt durch spezialisierte Fachbetriebe aufbereitet und inklusive Garantie angeboten.
Zirkular kann dank seiner langjährigen Erfahrung mit der Wiederverwendung von Bauteilen eine optimierte Plattform anbieten, die den Käufer:innen Vorteile von der Produktdokumentation bis zur Lieferung bietet. Beispielsweise können Bauteile für eine “Just in Time” Lieferung bei Bedarf bis zu 24 Monate zwischengelagert werden. Zusätzlich besteht die Möglichkeit, Bauteile für einen Monat zu reservieren, um sie während der Entscheidungsfindung oder technischer Abklärungen zu sichern.

Der Shop ist an das Planungstool Planular® angebunden. Somit können Eigentümerschaften Bauteile aus ihren Quellobjekten direkt über den Marktplatz verkaufen.
