IoT-iBMS: IoT based intelligent management of HVAC

The developed concepts, read as a new climate control solution, are tested in full scale in 4 meeting rooms.

The project has developed “IoT-iBMS” – an IoT based solution for intelligent control and monitoring of climate in rooms. Data for ventilation and energy are send to the cloud, and users and maintenance responsible can from a pc or phone on-line follow the ventilation and climate. Besides that, the weather forecast is automatic locked and schedule for next meeting including number of meeting participants are incorporated in the control.

Knowledge about time for start of meeting and number of expected meeting participants together with knowledge about weather forecast, gives intelligent control of heating and ventilations of the meeting rooms, including time for start of air condition.

In the municipality, where the case building is located, the energy prices are increased in the period from 5pm to 8pm, and in this period the ventilation and heating system can be stopped completely, unless the room(s) are booked. Maintenance of night setback temperature can in the future be dependent of on-line price signals from the energy supplier (energy flexibility). The hypothesis that energy can be saved by increasing the use of data is exemplified. With increased focus of the use of the individually meeting rooms and intelligent booking of these, further savings can be made. The saving is 40% for electricity.

The project is co-founded by the Elforsk program with project number 351-033, and conducted by the participants listed below: Klemen Rupnik Lindab A/S Anders Vorre Lindab A/S Peter Svendsen Lindab A/S Göran Hultmark Lindab A/S Martin Hansen DEAS A/S Claus Klint IBM Danmark Aps Danny Olsen Teknologisk Institut Merete Lyngbye (Project responsible) Teknologisk Institut.
