Avans Hogeschool - Priva ECO

Avans University achieves energy savings of almost 40%

“Priva ECO helps us reach our quality and sustainability goals.”

In a pilot project at the ’s-Hertogenbosch campus, Avans University of Applied Sciences (Avans Hogeschool) achieved savings of almost 40% on natural gas consumption for heating. “But, for us, it's about a lot more than saving money,” argues energy coordinator Sebastian van Velthoven. “Priva ECO helps us reach our quality and sustainability goals.”

Avans is one of the larger universities of applied sciences in the Netherlands, with more than 60 degree courses, 33,000 students and 2,800 staff. Across 14 sites in Breda, ‘s-Hertogenbosch, Roosendaal and Tilburg, the school is known for its commitment to quality. In Keuzegids Hbo 2020, which assesses and compares the quality of higher education in the Netherlands every year, Avans was nominated the best applied sciences university in the Netherlands.

Sustainable, the new normal

But sustainability is equally high on the Avans agenda. The school believes its students are the future and will play a major role in the transition to a more sustainable society. Avans is there to guide them. Sustainable development is a constant thread running through the university’s teaching, research activities and, of course, its working and learning environment. This ambition is also expressed in practical terms, including in the campus facilities. All buildings, for example, have to be at least energy neutral by 2030.

“That’s quite a challenge for a university with a huge variety of buildings in different locations,” admits Sebastian van Velthoven, the university’s contract manager and energy coordinator. “Among other things, we’re investing in renewable energy, with solar panels on every rooftop, and we’re drawing up energy saving plans for all our locations to systematically reduce consumption.

”Unexpected savingsWith this in mind, Avans had for some time been looking for a good system to control and monitor its heating systems. At the end of 2019, the university decided to set out on a pilot project with Priva ECO on the campus Den Bosch. This covers a fairly large area of more than 35,000 m2, with two large boilers and 38 air handling units.The results far exceeded expectations. “We had expected to save around 25% on natural gas,” confesses Sebastian. “Anything above that would be a bonus. But ultimately, in the first two months of the year – before the Covid-19 lockdown – we were already achieving savings of almost 40% compared to the same period in 2019".

Hidden problems

“Implementing Priva ECO also uncovered a number of hidden pain points in our current installations,” says Sebastian. “For example, we noticed that problems arose when we wanted to switch to heating at lower temperatures. With a few simple actions, we immediately got higher efficiency from our installations.”

“We often find that Priva ECO reveals sub-optimal operation in existing installations,” says Frank Visscher, who was involved in the project as a Priva consultant. “Our software calculates exactly how much energy is needed to get a room to a certain temperature and sends exactly that power to the installation. If that doesn't turn out to be enough to heat the room, you know something’s wrong somewhere. With conventional controls, these things all too often remain hidden. The only thing you see is high consumption.”

Student experience

But energy saving, however spectacular, is only one side of the story. “What perhaps appealed to me most about Priva ECO is that user comfort is central,” says Sebastian van Velthoven. “And that’s extremely important to us. Because students who choose Avans choose quality. That’s not only reflected in the quality of the education we offer, but also in the appearance and perception of our buildings.”

“A good indoor climate – not too hot, not too cold – ensures that students get even more from their experiences. With lockdown, we don't have much insight into this yet because students spent a lot of the spring at home. But I'm pretty sure we'll see the positive effects in the autumn.”

The future is now

Sebastian looks back on the collaboration with satisfaction. “Of course there are the great results, but we also learned a lot during the pilot project about how we can make our installations and our buildings even more sustainable. The collaboration with the various parties went smooth, despite some delays in implementation. It’s natural that you have to deal with a number of unforeseen circumstances in a pilot project.”

In the meantime, the project is still moving forward. “In the same building, Priva ECO is now also controlling cooling, and we’re already looking at how we can extend the system to all our buildings and locations.”
