"Daylighting and electric lighting do not inherently know how to play together in the same space," says Judie Porter, CEM, LEED-AP, program manager for Architectural Energy Corporation."Add photosensors to the mix without understanding exactly what the sensors see or how the electric lighting responds to the control settings, and the results may be undesirable."

One example, she says, is using the software to identify glare issues, which can make a space uncomfortable."We have seen examples of a Band-Aid, such as paper taped on glazing, used to remedy a high daylight illuminance design in a computer room with a low task illuminance criterion," Porter adds."We have also seen photosensors rendered useless by occupants taping over the sensor because they were placed or commissioned improperly and light levels in the room were not adequate."

With proper planning and design of the daylighting controls, she points out, these problems can be avoided in many projects.
