In the second half of July, work will be carried out on the air-handling system in the Kamerlingh Onnes Building. This will involve replacing the motors for the air supply and extraction in each section of the building.

During the works, air circulation in the affected areas may be temporarily reduced. This may be noticeable as reduced ventilation, less cooling in hot weather and possibly some noise disturbance. When it is hot, staff can open the windows for extra ventilation and cooling.

The works will take place according to the schedule below:

Date	Building section / rooms
16 and 17 July	A3, Moot Court rooms, offices in this wing and Lorentz lecture hall
20 and 21 July	B- and C-wing ground floor: work group rooms and lecture halls
22 and 23 July	A-wing: offices and lecture halls, including C1.31
24 and 27 July	Library and restaurant
28 t/m 31 July	Offices in the 1st, 2nd and 3rd floor

The classrooms in question will be off-limits on the days the work is carried out. We ask for your understanding regarding any temporary disruption caused by this necessary work.
