DaySwitch™ Demonstration Project
A small demonstration and evaluation of the DaySwitch™ was undertaken at the University of Oregon and at the Lighting Research Center to determine its operational issues, energy savings capabilities and building occupant acceptance. There are two reports on the DaySwitch™ demonstrations, one for each site. While the DaySwitch™ is not yet commercialized, the demonstration results are very encouraging.

Mechanical Shade Control Device
A small demonstration and evaluation of a mechanical shade control device developed by the University of Oregon's Energy Studies in Buildings Laboratory was undertaken to determine the device's operational issues, building occupant acceptance and energy saving capabilities when used with lighting photocell controls. There are two reports on the mechanical shade controll device, one from the test sites at the University of Oregon and the second from the test sites at the Lighting Research Center.
