Building technology/renewable energies
Building services engineering - or more correctly technical building services installations - include flue gas systems and other installations such as heating systems. Systems for utilising renewable energies are now regulated separately. This includes solar energy systems.
Many of these systems can be erected without a permit. The following table contains key points for differentiating between projects that do not require a permit and those that do.
