Open Source Building Cadastre

The information about a plot of land will be constantly available throughout its lifecycle: Information is also a resource which needs to be sustainably used and not wasted.

THESIS 05

OPEN-SOURCEBUILDING CADASTRE: BUILDINGS WILL HAVE ABAILABLE DIGITAL FILES CONTAINING THEIR DATA - WHICH WILL PUT AN END TO WASTED DATA.

In 2030, the digital open source building cadastre will be the ‘single source of truth’ – digital and freely available to provide information about the size, location, use, land register entries, land tax and so on for each plot. Even data for due diligence processes, the status of the building, necessary maintenance work, energy consumption and rental income will be available in the Cloud.

Throughout the lifecycle, this open source software will guarantee complete and high quality data. The information will be permanently and automatically updated in a real estate cloud so that the updated data for every day can always be clicked on. This system will be based on Blockchain technology which will ensure the availability of the data. The existing databases and platforms will continue to communicate via secure interfaces.

Since the information is stored as an important ‘resource’ instead of wasting it, open source building cadastres are sustainable.

Whereas the purchase and sale of properties is a rather changeable and variable process, the basic data for the land and building as a matter of course remains constant. The use of digital data and services, as well as Big Data, will ensure that the sum of all data is included in the digital open source building cadastre.

“For me, ‘open source’ is one of the most relevant topics in the real estate industry. I believe that, in future, all data will be readily accessible – and the possibilities are huge! Networking and the intelligent processing of data – thus making it usable – will be key.”
Thomas Häusser Partner at Drees & Sommer

MADASTER – MORE THAN JUST GOOD INSIGHT

One step towards a ‘single source of truth’ is Madaster – the global online cadastre for products and materials. From the platform of the nonprofit association, the owners and facility managers of buildings and infrastructure can arrange for a webbased material passport to be produced at any time for their buildings and all registered materials and products. The Madaster material passport gives an insight into the physical assets of the registered properties and shows the current residual raw material value of the buildings.

In 2020, Drees and Sommer in Switzerland started a partnership with Madaster to promote the circular economy in Switzerland and strengthen the idea of using buildings as a repository of raw materials.
