INTERFACE - Development of multifunctional element facades for the energy-efficient refurbishment of non-residential buildings
Objectives

Initial situation:
When refurbishing office buildings, the user should be disturbed as little as possible. This can be achieved by retrofitting multifunctional unitized façades (integral façades). As part of this research project, their suitability in terms of prefabrication, energy-efficient refurbishment potential, the integration of decentralized supply systems and energy generation options will be investigated, while at the same time taking architectural aspects into account. A test setup consisting of a sample façade and climate chamber will be developed for this purpose. Subsequently, laboratory tests are planned for the assembly of the sample façade.
Objective:
The aim of the research project is therefore to assess the suitability of multifunctional unitized façades (integral façades) for the refurbishment of non-residential buildings
(primarily office buildings, schools, etc.) under the following aspects:

Modularization of façades (prefabrication and "modular system")
Renovation potential in operation (architecture, building physics and technical building equipment)
Decentralized supply systems (heat, electricity, cooling, air)
Sustainable decentralized energy generation (electricity, cooling)

Procedure:

Step 1 - Basic assessment and potential analysis
Development of problems and opportunities in the refurbishment of buildings from the 50s, 60s and 70s, taking into account various existing office buildings.

Step 2 - Sample façade - development on the building (mockup)
A mockup (a test setup consisting of a sample façade and a climate chamber) is developed from the knowledge gained. The sample façade is to be developed as part of a refurbishment project. The opportunity to test findings from the preliminary study under real conditions
on a concrete example is unique.

Step 3 - Guidelines
The results from the mock-up studies are compiled into a guideline. The priority here is to check the specifications from the preliminary study with the knowledge gained from the mockup test in practice.
In the ''Demo'' research project, the findings from these studies are to be implemented in a 1:1 model on the BS4 high-rise building, 9th floor of the TU BS and monitored and evaluated over 3 years under real conditions.
