2008 - Riedel Recycling
In Moers (nearby Duisburg in Germany) Riedel Recycling, an industry of preparation and storage of building materials, has installed a record thin film PV plant on an old building previously used for coal processing: more than 11 thousand modules in Cadmiun Telluride (CdTe), manufactured by american industry First Solar, with a peak capacity of 837 kWp, have allowed to this installation to become the widest in Germany adopting thin film on a pitched roof of 9.500 square meters.
SOLAR ARCHITECTURE
| Energy and architectural concept | – Energy optimized – Maximum power |
– Partially adapted to building skin – Roof |
– Partially adapted to building skin – Facade |
– Total building skin |
| Energy and architectural language | – Evident emphasized PV | – Low recognizable PV | – Hidden PV Mimicry |
SOLAR AND BUILDING SKIN
| Standardization vs customization | – Standard PV components | – Low customized components | – Highly customized components | |
| Building skin technology | – Roof added system | – Facade added system | – Roof integrated system | – Facade integrated system |
SOLAR AND BUILDING ENERGY CONCEPT
| Solar and building energy efficiency | – No special energy target | – Standard energy target – (state of art, normative) | – High energy efficiency – (Passive-house, n-ZEB, PEB) | |
| New building or refurbishment | – New building | – Refurbishment (ordinary building) |
SOLAR AND URBAN CONTEXT
| Solar and urban density | – Low-density building | – Medium-density urban context | – High-density urban context | |
