Energy efficiency

Energy monitoring equipment has been purchased and installed at the telescope to allow for a detailed view of how and where electricity is spend under normal operations. The aim is to identify areas where savings can be achieved. As expected, the cooling system of the telescope is by far the biggest energy consumer (the next biggest that has been measured is the computer room in the service building that uses more than 10 times less). No measurements have been made yet in the telescope building itself. To achieve any savings effort should clearly focus on how the cooling system is used. It is interesting to note that the cooling unit consumes almost the same during nighttime as during daytime.
