Considerable energy savings

The University Library in Groningen is the first educational building in the Netherlands to incorporate the Climotion system. The successful pilot project conducted in the auditorium of the Academy Building shows that the Climotion system regulates fresh air and a pleasant temperature in an energy-efficient manner. The University of Groningen (RUG) expects to achieve up to 30% energy savings compared to a traditional ventilation system. It is expected that, following the renovation, the library will progress from a B Energy-label to an A Energy-label.

Improving the indoor climate

To better accommodate the growing number of visitors to the university, the library is undergoing renovation. The number of study places is being increased from 1,700 to at least 2,700, with the possibility of further expansion in the future. RUG has set itself the goal of improving the indoor climate considerably. This is made possible thanks to the successfully tested Climotion system in the Academy Building auditorium.

Stable and comfortable indoor climate

The Climotion system supplies the library with sufficient fresh air and ensures a consistent temperature and an ideal indoor climate. At the same time, the system uses far less energy than the traditional HVAC system. In keeping with the growing number of visitors, this will result in energy savings of around 20%.

Comfort-based climate regulation

These savings are possible because of the user-dependent amount of air that is climate controlled. This means that climate regulation is based on comfort – consisting of temperature and air quality – and not on the prescribed amount of m³ of fresh outside air per person. The air measurement is so efficient there is a surplus of warm air, and cold air can be used more often to conserve energy.
