Building-integrated photovoltaics (BIPV)
Future-proof buildings are highly energy-efficient
The EU Energy Performance of Buildings Directive 2010/31/EU has required nearly zero-energy performance for new buildings since 2021. Schüco combines thermally insulated building envelopes with building-integrated photovoltaics (BIPV) to provide solutions for highly energy-efficient buildings.
BIPV can support cost-effective building design
Since 2021, CO₂ emissions have been subject to carbon pricing and reflected in building assessments through the energy performance certificate. This can change the operating framework and should be considered when assessing a building’s economic viability. Building-integrated photovoltaics can support the planning and operation of real estate, making them relevant to investors and operators. A building that generates its own electricity can help reduce operational CO₂ emissions. Under the German Energy Saving Ordinance (EnEV), solar power generated on site may be deducted from the calculated electricity demand for the energy performance certificate, helping to reduce primary energy demand.
A wide variety of options for architectural freedom
A PV module mainly consists of interconnected solar cells positioned between front and rear glass panes. A wide range of cell and glass options gives architects considerable design freedom and enables individual building concepts. The modules provide the functional and visual properties of conventional glazing. The colour coating on the front glass and the choice of cover glass define the appearance of the PV infill panel. Structure, size, format and colour can be combined in many ways.
In the right light
To help make life shine brightly, our PV modules make use of the physical principle of interference. Only the desired colour tones in the light are reflected and this provides the effect of a visible colour for the façade. The colour units are then attached to the rear glass of the front panel and this provides protection against wind and weather. The result is unique colours with maximum efficiency.
Generating power across all orientations

Schüco’s range of BIPV systems supportsapplications on different building orientations. PVmodules can generate electricity on north-, east-,south- and west-facing façades. Yield depends onfactors including orientation, inclination, shadingand local conditions. Under suitable conditions,companies can benefit from a 360° solution.
North- and east-facing façades generally generateless electricity overall than south- and west-facingfaçades. However, with dynamic electricity tariffs,generation can be distributed differently over time.Under suitable conditions, a 360° BIPV system cantherefore extend the generation window andinfluence energy costs and the building’s energy balance.
Smart energy opens up further potential
Typically, around one third of solar power can be consumed directly. Direct consumption is most effective when solar yield coincides with electricity demand. The actual share depends on factors such as individual demand and system design.
Adding battery storage can expand the potential of the PV system. Under suitable conditions, it allows a further share of generated solar power to be used on site. Electric heating and cooling systems, such as heat pumps, and electric mobility can create additional uses for self-generated electricity.
Any remaining solar power is generally fed into the public grid in return for remuneration. System connectivity and dynamic electricity tariffs may create further opportunities when assessing economic viability. For certain models, a PV system or self-generated electricity may be a prerequisite for achieving greater self-sufficiency and lower ancillary costs.
