Zero-energy building

• Sustainable generation of electric energy

• Net energy consumption of zero over a typical year

Energy-positive building:

• Generates more energy that consumes

• Feeds surplus electricity back into the grid

The idea of BIPV

BIPV - Building Integrated Photovoltaics

BIPV refers to systems and concepts in which photovoltaic modules are incorporated into various architectural applications, especially as an alternative to conventional building materials used in the areas corresponding to roofs and façades (e.g. roofings, glass roof and elevation systems and façade-covering elements)

BIPV – potential benefits

• Direct consumption of produced energy• Low transmission losses• No additional requirement for land• Good use of existing mounting and grid

infrastructure• Great opportunities for architects• Modern and ecological image of the building• Saving on conventional building materials• Better module protection possibilities

Architectural concepts of PV applications

Solar panels are suitable for replacing many of the architectural elements such as:

• Roofings

• Elevation elements

• Windows

• Shutters, canopies and sunshades

PV adaptation for BIPV requirementsTransparent cells

Advantages:

• Partial shadowing of the interior, partial transparency

• Cells come in different colours.

Drawbacks:

• Less than 10% efficiency

• A new, costly technology

Examples of applications:

• Greenhouses

• Glassed-in vantage points (roofing)

Conclusions

The application of solar panels on buildings is economically, technically and architecturally attractive.

The BIPV technology has been now at the stage of dynamic development.

Scientific research has been conducted on adaptation of new solar cell types for the purpose of BIPV.
