Today, even listed buildings can often be equipped with photovoltaic systems. New regulations in several federal states allow a more liberal approval practice for solar systems on listed buildings. Owners of historic buildings now have the opportunity to use solar energy to cut electricity costs and reduce CO₂ emissions without significantly altering the appearance of the building.

In Germany, the building sector accounts for around 30 percent of energy consumption and CO2 emissions. A large proportion of the approximately 15 million detached and semi-detached houses are outdated in terms of energy efficiency. However, modern insulation and efficient heating systems based on renewable energies can significantly reduce energy consumption and increase living comfort at the same time. Refurbishment actively contributes to...
