REAL-TIME BUILDING PERFORMANCE AUDIT


The 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.

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

Professor Jarek Kurnitski who is 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 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 an easy and partly automated routines if buildings will be connected to the platform developed in the project. 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 are planned to be connected to the IoT platform and tools developed in the project. The platform will split performance monitoring functions from maintenance related automated diagnostics. One of the long-term goals for the city of Tartu is to become a climate-neutral city by 2050. Real-time overview of the energy consumption and indoor climate condition of municipal buildings portfolio helps them to reduce the carbon footprint of buildings while maintaining good indoor climate quality.

The user interface of the platform consists of three dashboards with increasing detail level on information provided: Executive, Departmental and Maintenance dashboard. The project focuses to educational buildings because their indoor climate is essential for achieving high learning performance that has implications to national competitiveness. The results can be utilized by any large real estate portfolio owners.

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, implementing machine learning applications and new performance analytics tools for benchmarking and for automated maintenance need diagnostics. Group of experienced scientists on 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.

This project is led by Prof. Jarek Kurnitski and managed by Kalle Kuusk at the Smart City Centre of Excellence.


The pilot project is 100% financed by the European Regional Development Fund and the Estonian Ministry of Education and Research
