This pilot team aims to improve operational energy performance and indoor climate through the digitalization of facility management in large real estate portfolios. Continuous monitoring of energy, ventilation and indoor air quality in buildings results in big data for which performance analytics capable of identification of faults and malfunctions in building technical systems as well as in building operation will be developed. 

Professor Jarek Kurnitski, the leading researcher in this pilot project comments that “Cities and other large real estate owners have hundreds of buildings they have to manage to deliver good indoor environment to the end-users. At the same time buildings have to be highly energy-efficient that is possible if all building technical systems operate properly. This is achievable with careful monitoring and maintenance for which new digital tools are to be developed.

Real-time building performance audit will offer to buildings owners and building operators automated energy performance, indoor climate diagnostics, and fault detection. An evidence-based knowledge about the energy use and indoor climate in the building portfolio will enable to prioritize renovations and optimize energy use without compromising indoor climate quality.” 

In total, 45 educational buildings of Tallinn, Tartu and TalTech campus are planned to be connected to the IoT platform and tools developed in this pilot project. The project focuses mainly on educational buildings because their indoor climate is essential for achieving high learning performance that has implications for national competitiveness. The results can be utilized by any large real estate portfolio owner. 


One of the long-term goals for the cities of Tartu and Tallinn is to become climate-neutral cities by 2050. A real-time overview of the energy consumption and indoor climate condition of municipal buildings helps them to reduce the carbon footprint of buildings while maintaining good indoor climate quality. 

Implementation of real-time building performance audit requires solving research challenges to collect and process the right data about the energy performance and indoor climate with a minimum number of sensors and implementing new performance analytics tools for automated energy performance and indoor climate analyses. A group of experienced scientists in the fields of energy performance and indoor climate of buildings, diagnostics and fault-detection of sensor networks, and machine learning applications are involved in the pilot project to achieve the best quality outcomes. 

The pilot project is part of the "Implementation of the Smart City Centre of Excellence Support Measure" (Subsidy No 2014-2020.4.01.20-0289) financed by the European Regional Development Fund and the Estonian Ministry of Research and Education.
