By using prefabricated timber frame façade elements with integrated building installation for renovation, iNSPiRe can bring buildings up to standard while habitants remain inside.

As existing building is fully inhabited it was necessary to combine timber elements for the storeys above ground level and a conventional perimeter insulation system for the basement where there will be contact with the soil. The first step was digging a workspace around the basement and installing new windows and an insulation system to the basement walls.

Before more extensive work was carried out, scaffolding was erected around the building. Gumpp & Maier were responsible for the carpentry aspect of the project and worked together with the architects and planning team. Any work that needed to be carried out by other compa- nies was either assigned to project partners or assigned to sub-contractors by the architect or by Gumpp & Maier.

Before the building could be renovated with prefabricated timber elements, a complete digital measurement of the building was taken using tachymetry. The TES (Timber element system for energetic renovation of the façade) has been developed in earlier research projects with the participation of Gumpp & Maier. The iNSPiRe project now uses those façade elements as a basis for adding value to the renovation system. Pipes, ducts and wires for domestic water, heating, ventilation, electricity and solar energy gen- eration are integrated to the timber frame façade elements during prefabrication in the workshop, ensuring high quality and reduced building time on site.
In order to eliminate energy loss caused by thermal bridges, the exist- ing balconies were cut off. In its finished state, the building will have a closed wall with large window open- ings created by the mounted timber façade elements. This means that the space in the rooms, behind the balconies, is extended and there is a minimisation of thermal losses via the façade. The sills of the existing windows were removed during this step.
