A smart district heating project in Tampere, Finland, has achieved cost-savings of 10 per cent and is helping to reduce the carbon footprint of student accommodation in the city.
Tampere Power Utility is working with local company Enermix Oy to deliver the service and algorithms are also being developed for other types of buildings, including offices and schools.
The Tampere Student Housing Foundation (TOAS), which wants to lower its carbon emissions to zero, is testing the service in 11 of its buildings.
The service uses apartment-specific sensors that measure the temperature and humidity while artificial intelligence (AI) controls heating according to needs during different times of the day and year.
It balances peak district heating outputs and optimises the need for heating in buildings. For example, the AI prevents any unnecessary heating during summer and when the days get colder in autumn, heating does not need to be switched on at once as it is stored in building structures.
