Building-related technical installations are becoming increasingly complex. This is the result of additional societal attention to health and energy use, greatly increased laws and regulations, technical developments and the demand for greater convenience and comfort.

This includes the electrical installation with energy generators such as solar panels, energy storage or charging stations for electric vehicles or vessels as well as facilities for cold and hot water, heating, cooling, network cabling and possibly central dust extraction. This increases the need for proper maintenance and advice for the sake of economic life and comfort preservation.

Regular inspection and maintenance according to current laws and regulations can ensure safe and energy-saving operation.
