By the end of 2022, Sepp Lorber and Franz Freundorfer designed a new prefabricated standard element for the serial renovation of small-scale exterior walls. This base element can be filled with various insulation materials and is finished externally with a plaster layer or a wooden facade. The windows already include the exterior reveals, the windowsill, and optionally, the shading. All these elements are installed in the window manufacturing process. The integration of the proprietary ventilation system smartvent will be completed later this year.
Naturally, there is also a version available for large-scale exterior wall sections. Both versions can be combined in smartshell reno.

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.
Windows
In this system, the optimized window connection offers the greatest potential for savings. Window jambs and optional sun protection are pre-installed in the window fabrication process. Sepp Lorber and Franz Freundorfer intentionally opt for on-site window replacement, handling windows individually. This approach effectively compensates for large dimensional tolerances, and residents experience minimal disruption, as the new window, including jambs, is installed immediately after the old window is removed.
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.
