Transformation of school building to dwellings in Tilburg, the Netherlands

​(geo-cluster West Europe)



The school building will be transformed into 6 dwelling units based on collective self-organised housing (CSO) principle, which is an owner-occupied development in collaboration with a housing association. 
Replication potential is high: The current building is owned by municipality which aims to explore potential for reuse of existing building and urban condensing of inner city.​

​​Current situation:

Dutch energy label 'F'. Energy savings after deep renovation: Zero energy consumption on the supply meter on yearly basis.

​​Building morphology:

Brick walls, concrete uninsulated floors, wooden roof. One layer building well-suited for prefabricated rooftop extension.

​​Prefab deep renovation solutions:

Adding prefabricated facade elements, prefabricated lightweight rooftop extension, prefabricated integrated installation, smart flexible insulating floor with accessible ducts.

Potential cost reduction in large series (upscaling) is 10-15%. Cost savings with comparable new zero energy housing is about 20%. Traditional building time for this type of new housing is 11 months. Building time of roof-top extension dwelling is 2 days. Planned building time for transformation with implementation of all innovations is 5 months.
