Digitalization inside and outside: Combining data from the building's outer shell and interior spaces

Situation

Stadtwerke München GmbH (SWM) is one of the largest German municipal supply and service companies. They are the largest public utility in Germany and one of the largest European public utility companies. Since 2008, the expansion of renewable energy has been a central part of the corporate strategy. The company sees itself as a pioneer in the heating revolution.

Together with Lumoview Building Analytics GmbH, Stadtwerke München has set itself the goal of scanning their customers' existing buildings
and to prepare them as BIM models. This allows renovation and maintenance tasks to be carried out more efficiently and cost-effectively and new business models, such as digital energy consultations or heat pump installations, can be developed.

Due to the high costs and time required, only 2D floor plans have been used so far. With Lumoview's new technology, interiors can be captured in just 2 seconds per room and digital building twins can be prepared in the cloud in a highly automated manner.

Until now, traditional methods such as tape measures and laser measuring devices have been used to measure building envelopes. An employee
I had to pick up the measurements by hand, which was very time-consuming and prone to errors. In addition, it was difficult to collect data accurate to the centimeter. This often led to problems during the planning and implementation of renovations. Customers also had to wait a long time for results.

Challenges

After finding an ideal partner for digitizing interiors with Lumoview, the challenge was to find a solution that would allow façade and roof measurement to be carried out faster, more precisely and more efficiently. It should also be possible to combine the data with the building interior data to create BIM models.

Solution

Thanks to digital façade and roof measurement using drone and artificial intelligence from Airteam, a solution was found that met the requirements of Stadtwerke München and Lumoview. After flying the drone on site, Lumoview can combine Airteam 3D CAD data with interior data and thus create BIM models quickly and efficiently.

Digital façade and roof measurement using drone and artificial intelligence made it possible to create BIM models more efficiently and faster than ever before. It now only takes 15 minutes on site to collect all necessary data on the building envelope. In addition, the data is accurate to the centimeter, which helps to create accurate renovation plans. The ability to combine building envelope data with interior data and create BIM models enables not only the energy advice offered by SWM but also the more efficient planning of photovoltaic systems on complex roofs. Problems can be identified and avoided in advance.
