Benefits of energy monitoring and optimization – seminar on ZenN findings, Malmö, Sweden

IVL Swedish Environmental Research Institute welcomed on the 17th of October regional building owners, energy company representatives, researchers and municipal officials for a seminar and discussion on the ZenN project findings. The meeting was held in the conference center of the establishment housing IVL'snew office in Malmö. Emphasis of the meeting was on the energy monitoring results of the Lindängen demo site and the benefits of energy monitoring and optimization. IVL’s Rasmus Andersson and Johan Larsson presented and discussed the monitored results and findings. Also, the CEO of the Lindängen building owner Trianon, Olof Andersson, presented the wide sustainability effects of the project.

- It was a delight to be able to share the ZenN project findings in a wide sustainability perspective to the participants. In an environmental perspective, the project displays an inspiring way forward for similar neighborhoods, foremost through the monitored 40 percent reduction in final energy use and 38 percent reduction in climate impact for the buildings, says Rasmus Andersson, ZenN research partner at IVL Swedish Environmental Research Institute.

From the seminar we concluded that it is important to decide what to follow up during monitoring of energy performance after renovation. It is also important to define the proper KPI:s, i.e. primary energy or bought energy. During the first time after the investment adjustments are very important in order to reach the expected targets. Individual measuring and billing, the experience from several participating building owners was that it is more important to inform about this than the billing itself. Sometimes the users see that the energy use is quite cheap, thus the energy use can increase. Some participants want to see a larger involvement of the energy companies in renovation measures, and then the energy performance could be lowered even further. Monitoring of energy performance still faces some challenges, e.g. costs, standards, knowledge and organisation. Property managements are often unable to allocate enough time and resources even for basic monitoring follow-up and evaluation of improvement possibilities.

A main conclusion from the seminar is that it is important with projects such as ZenN where this is developed further. In the future behavioural issues must be emphasised even more.
