One focus of building modernization is energy modernization. This includes changing the energy sources of heating systems and implementing decentralized energy supply concepts with renewable energy sources, such as tenant electricity projects with solar systems. The industry relies on the reliable service of regional craftsmen.

In everyday business, however, digital devices such as notebooks or tablets have so far been used mainly for mail traffic or online banking. Mobile solutions or online platforms are still rather rare at present.

The first solutions offer craftsmen from the modernization sector the opportunity to simplify their administration with customer or project data. This saves time and reduces uncertainty in the businesses. In addition, platforms are emerging on which businesses can make their services, such as insulation or modern windows, visible. This creates transparency and can attract more customers.

Another trend is BIM planning and the associated creation of digital twins. With the help of these models, modernization and other work on a building can be identified at an early stage and carried out more cost-effectively. Also not to be neglected is the modernization of real estate into smart buildings, which are often smartly networked by means of IoT technology and thus become controllable.
