The continuous monitoring of energy, ventilation and air quality in hundreds of buildings generates big data. Analytics were developed to handle this data, allowing for real-time monitoring and comparison of buildings, diagnostics and real-time detection of faults in technical systems.

The buildings included in the project are a good representative sample of municipal buildings: schools, kindergartens, offices and social welfare buildings. In addition to local government buildings, the project also includes TalTech campus buildings. A total of 45 buildings were added to the platform.

Data processing and management tools were developed using the data from these buildings. On the platform, performance monitoring functions are separated from maintenance-related automated diagnostics.

As a result of the project, upgraded sensors were installed in 20 buildings owned by Tallinn to enable monitoring of the indoor climate. It is possible to perform automatic diagnostics on the condition of the buildings. A three-level control board was built, through which it is possible to monitor the condition of the buildings and assess repair and investment needs.
