smartshell reno is the first building system certified by the Passive House Institute as a "renovation system." This serial construction system, detailed with full-scale cross-sections, aims to sustainably increase the renovation rate.

Opaque Building Envelope

The system is specifically designed for building renovation. The investor determines the energy efficiency level at the start of the renovation process, allowing all essential details to be defined early in the planning phase and adjusted as needed to meet project-specific requirements.

Large wall surfaces are efficiently insulated using highly simplified, floor-height wall components up to ten meters wide. For smaller wall surfaces, specially developed base elements are used.

Airtightness Concept

The airtightness of the walls is ensured by the optimized exterior plaster. Once windows, roof connections, and connections to basement and floor slabs are installed, the first airtightness test is conducted. At this stage, all connection points remain easily accessible and can be adjusted as needed.

PV Modules and Building Services

In smartshell reno, the PV system, heating, hot water, and cooling are integral parts of the turnkey renovation.
