A Finnish University is implementing a remote management system to make its campus 15 per cent more energy efficient.
Developed by the Finnish Research Centre VTT together with Samsung, the system being deployed in the Otaniemi campus of the Aalto University in Helsinki, uses about 10,000 data points collecting information about energy consumption and indoor conditions.
The monitoring system gathers data on electricity, heat and water consumption, indoor temperatures, carbon dioxide concentrations, humidity, lighting intensity and electrical loads in the facilities.
The information is transmitted in real time to the on-site VTT and Korea Telecom remote management system, where it is evaluated. Further action can then be taken regarding heating, lighting or ventilation. Better timing of such actions with regard, for example, to the number of people in the room, improves the efficiency of these measures.
The project, involving about 100 buildings aims at reducing the energy consumption of the campus by 15 per cent at the first stage, with the ultimate goal of making it completely carbon neutral and energetically self-sufficient.
“Our goal seems within reach. The project is now half completed, with several locations already averaging 15 per cent energy savings, though it still needs another few years of follow-up to confirm the system’s effectiveness,” said the project’s senior scientist Janne Peltonen.
The university staff and students can follow the system’s data output on specially tailored apps on their smartphones and provide additional feedback.
In one of the student residencies at the campus, residents can follow electricity consumption of currently used household appliances or receive information about indoor air conditions. In some cases, energy consumption has been reduced by nearly 50 per cent.
The companies and research institutions behind the project believe it can find a much wider use. It is believed smart systems could help to save up to 20 per cent of energy used in Finnish municipalities.
