THERM-opti-BALCONY-P2 - Thermal Optimized Renovation of Balconies Phase 2: In-Situ-Pilot-Station
Starting point / motivation
As for attaching thermal insulating a posteriori on exterior walls in the course of the thermal renovation of existing buildings, pre-cast cantilever balconies represent a particular problem.
According to the state-of-the-art, the common custom is
- to tear down the balconies before the attachment of the thermal insulation and to reconstruct them thereafter as a self-supporting construction with posts on distinctive foundations, which is in many cases technically not feasible or aesthetically unwelcome, or
- to preserve the existing balconies which leads to severe thermal compromises because the balconies form heat bridges through the newly mounted insulation, or
- to just omit the balconies after the thermal restoration of the building which, however, leads to a blatant deterioration of the indoor environment quality and to a occasionally dramatic loss of value of the real estate.
Contents and goals
The ongoing project THERM-opti-BALKON studies the THERM-opti-BALKON-System under laboratory conditions. This system allows the thermally decoupled new construction of balconies on thermally rehabilitated facades with optimal practicality and cost optimized.
The project THERM-opti-BALKON-P2 (Phase 2) uses the THERM-opti-BALKON-System's current state of development and implements it on a 30-year-old building under real conditions in form of an in-situ-pilot-station.
Objects of study of this in-situ-pilot-station are
- a building object analysis process - metrological monitoring of the existing building
- laboratory experiments and numerical calculations on the abstracted building
- monitoring of the long-term behavior of the system
The steady further development of the overall project THERM-opti-BALKON is ensured by applying the iterative problem-solving methodology by E. Fleischhacker (1994).
Application of the THERM-opti-BALKON-Systems is expected to result in
- a simple method of finding the location of the existing reinforcement
- architectural concepts
- knowledge about the long-term behavior of the system
