Review of the live webinar from 13.03.2025: Smart technologies for sustainable buildings
Digitalization is transforming building management forever – especially in the areas of water, district heating, and heating. But how can smart metering, building management systems (BMS), and building information modeling (BIM) contribute to reducing energy consumption and making processes more efficient?

Our live webinar on the opportunities of digitalization in building management took place on March 13, 2025.
Our ESG experts Daniel Schreiner and Tatiana Stuck provided practical insights into the potential of smart metering, building management systems (BMS) and building information modeling (BIM).
Among other things, the following were discussed:
- Optimization of energy consumption through smart metering
- Increased efficiency with modern building management technology
- Digital planning processes with BIM and their challenges

We thank all participants for their great interest!

Discover the optimization potential of your building now
Optimization potential
Low
According to the brief analysis of the building, the building appears to be in good to very good condition in terms of energy. According to the demand calculation carried out, the building has "low" optimization potential. Testing more energy-efficient operation of the building can be a good measure for maintaining energy efficiency. Optimized operation can lead to lower heating costs for tenants and CO₂ costs for the landlord. Individual CAPEX measures can also secure the current condition of the building in the long term.
Following the brief analysis of the building, we recommend that you review and implement targeted energy measures. According to the requirements calculation, the building has "medium" optimization potential, which speaks for further energy optimization. A full ESG report, including iSFP / DIN V 18599, is advisable for an exact determination. This detailed report is prepared after an on-site inspection by our energy efficiency experts and building technicians. As a result, sensible energy CAPEX measures as well as the associated costs and possible subsidies can be determined, identified and implemented with Purpose Green.
Following the brief analysis of the building, we recommend that you promptly review and implement energy efficiency measures. According to the demand calculation carried out, the building has "high" optimization potential, which indicates an acute need for action. We therefore recommend a full ESG report including iSFP DIN V 18599. This detailed report is prepared after an on-site inspection by our energy efficiency experts and building technicians. As a result, sensible energy CAPEX measures as well as the associated costs and possible subsidies can be determined, identified and implemented with Purpose Green.
