Renovation and maintenance Drift 21, 23 and 25

Utrecht University is to renovate the buildings at Drift 21, 23 and 25. The work includes maintenance and significant improvements to the buildings, including improvements to the indoor climate, accessibility and sustainability. During the works, the buildings will be closed. Other locations will be sought for teaching and offices.

Work in Drift 21

In Drift 21, new climate control installations and the electrics, lighting, data and AV installation will be replaced. The toilet groups will be expanded and a disabled toilet will be installed on the ground floor. The first floor will be made accessible for people with physical disabilities. There will be more meeting and community formation space at the new entrance near the lecture hall. The exterior and interior of the building will be completely painted, the windows will be fitted with vacuum glazing and the roofs and facades will be insulated wherever possible.

Work at Drift 23 and 25

Maintenance at Drift 23 and 25 consists of interior and exterior painting. Replacing the flooring in the teaching rooms and replacing all AV facilities. The air conditioning will also be maintained and adjustments made to improve air quality. Furthermore, top cooling will be installed which will provide more comfort in the building.

The buildings are also being made more sustainable. All fluorescent lighting will be replaced by LED lighting. This new LED lighting will be presence-controlled, and the light strength will be automatically adjusted to the light coming from outside. The brightness will also remain manually adjustable. The single-glazing will be replaced by vacuum glazing, and the windows will be fitted with new heat-resistant blinds on the inside. New motors that consume much less energy than the old motors will be installed in the air treatment system.
