9.6.2.2 Relocate and reorient fixtures to improve energy efficiency and visual quality.
This Measure goes one step beyond Measure 9.6.2.1 by relocating the fixtures to make them more effective. This Measure requires much more labor. In spaces that have more than one type of lighting, combine this Measure with Measure 9.6.3.
Relocation Strategy
Your objective is to provide good illumination while saving energy. To provide good illumination, observe the principles summarized in Reference Note 51, Factors in Lighting Quality. To save energy, try to achieve these objectives as you move fixtures:
•reduce lamp wattage. For example, moving a 4tube fluorescent fixture to an optimum location over a work station may allow two of the four tubes to be removed.
You can reduce fixture wattage in a variety of ways. Refer to Subsection 9.1 for incandescent lighting, Subsection 9.2 for fluorescent lighting, and Subsection 9.3 for HID lighting.
•eliminate fixtures. For example, in a restaurant that uses downlights for general lighting, relocating the downlights directly over the tables may allow you to remove half of them.
•increase the subdivision of control. For example, in a large office area, moving the fixtures over individual desks allows them to be turned off when the individual user leaves the space. Exploiting this opportunity usually requires circuit modifications and additional controls, as explained in Measures 9.6.4 ff.
