Initial situation, problems and motivation for carrying out the exploratory:
PV near to building is desirable for energy engineering reasons. Building integration of PV is architecturally desirable. This is currently for facades very rare because the whole construction is expensive and because the rigid module sizes can almost never be integrated into the facade planning. However, as soon as special formats become necessary, all profitability ends.
Therefore, PV systems are desirable
- which have simpler substructures,
- which are easier to produce in different formats,
- where defective modules can easily be replaced individual,
- which have a good PV yield
- based on the economic investment costs and
- which can be integrated into the new building as well as
- can be retrofitted to existing buildings.
Goals and innovative content compared to the state of the art / state of knowledge:
This exploratory project will now merge recently available products and technologies on the market into a new system. They are
- light PV modules embedded in plastic systems only and the
- new Velcro closure system for separable thermal insulation composite system façades.
Together they have the potential for a simpler, lighter and more cost-effective PV façade system to be tested for applicability, yield potential and safety.
Anticipated results and findings:
These are the first questions
- for fixing technology,
- for fire safty and
- for electrical engineering
to clarify.
Therefore, initial investigations on fastening technology, electro technical concepts and, above all, building physics and fire protection (determination of fire load, fire behaviour, etc.) should be carried out in order to estimate the application potential.
Subsequently, a follow-up project with real applications and monitoring is planned.
