Microwave detectors from CP Electronics have been used to control the lighting in the refurbishment of one of the campus buildings at Exeter University. The project involved the use of CP's MWS1 and MWS3 microwave detectors to provide dimming, daylight dimming, energy savings, absence and presence detection in open plan offices, corridors and cellular offices to improve energy efficiency. The building that has undergone the refurbishment is a nine storey structure and the top three floors have been completely refurbished whilst minor works have been carried out on levels two, five and six.
