In special-use spaces—such as museums, visitor centers, or fitness clubs—where visitors have limited access to lighting controls, meet the credit requirement by specifying that building staff will be available to adjust lighting conditions as necessary.
Although occupancy sensors do not offer occupants as much direct control, LEED allows occupancy sensors as a substitute to other lighting controls due to the energy efficiency benefits.
In multi-occupant workspaces the credit requires that controls are "adjustable to suit group activities and allow flexibility for different uses." It used to be that occupancy sensors with manual overrides plus an on-off switch would count, but that's not the case anymore. Project teams are now being held to demonstrating at least two levels of control in these spaces.
To meet credit requirements, task lighting does not need to be hardwired. Plug-in lamps or task lighting built into cubicles or office furniture is the most likely method of compliance.
Include in your credit calculations any spaces in which a person is likely to cumulatively spend a large part of the workday. These are considered “regularly occupied.”
Doing an early inventory has some advantages, although you may do it anytime, before or during the project’s performance period. If you document existing lighting controls and then assess opportunities for improvement before or early in project’s 12-month performance period for recording energy data, you can help the project's energy performance as measured for EAp2 and EAc1.
