![]() ![]() The allowances are calculated as lighting power under control multiplied by the applicable space control factor. For example, occupancy sensors controlling open-office cubicle lighting fixtures employing continuous dimming operation for personal light level control could provide a 30 per cent interior lighting power allowance bonus. ![]() As previously mentioned, when additional control methods are employed on top of mandatory requirements, an interior lighting power allowance may be generated to offset lighting loads in other locations. Reduce lighting power by at least 50 per cent within 30 minutes of all occupants leaving the space.Ĭontrols will also benefit lighting designers. Often an area identified for energy savings, stairway lighting control is one new requirement using the new sequence of operations of lighting controls. ![]() Additionally, a vacancy sensor will be required to automatically turn off lighting in the bathroom within 60 minutes of the occupant leaving the space. A common approach to error-proofing this process is to employ a device requiring the room keycard be inserted in a slot to activate the lighting circuits. A control device will be mandatory near the entrance door in new construction projects to control all permanently installed luminaires and switched receptacles. Vacancy detection systems are now required for room lighting in newly constructed hotels. Manufacturers are ready to meet this demand with simple, two-pole, wall-switch sensors or more capable digital lighting management systems that can support more complex requirements (Figure 2). Digital lighting controls are now available to meet the new American Society of Heating, Refrigerating, and Air-conditioning Engineers (ASHRAE) 90.1-2010, Energy Standard for Buildings Except Low-rise Residential Buildings, bi-level lighting control requirements-ĥ0 per cent auto-on, vacancy control, and plug-load control integration. ![]()
