This pilot credit is proposed to expand on the current lighting requirements, in order to address the quality of the lighting in a space.  Quality criteria focus on illuminance and reflectance to attempt to maximize occupant comfort and productivity.

Credit Specific

1. For suspended, wall-mounted, freestanding or partition mounted direct/indirect ambient lighting provide manufacturer’s product information and cutsheet.
2. For task-ambient lighting solutions that achieve recommended IESNA illu-minance levels with the combination of both systems provide manufac-turer’s product information and cutsheet.
3. To demonstrate an efficiency of greater than 50% for all luminaires provide manufacturer’s product information and cutsheet.
4. To demonstrate sources with more than 50 lumens / Watt for 95% of the demand power, provide a comparison to IESNA/ASHRAE and manufac-turer’s product information ad cutsheet.
5. To demonstrate a surface brightness of less than 10,000cd/m^2 for all lu-minaires with luminous parts within an 11-degree field of view from 4 feet above finished floor, provide on-site measurements or product data for fin-ishes
6. To demonstrate an average wall-surface-to-work-surface illuminance ratio that does not exceed 3:1, provide on-site measurements or product data for finishes
7. To demonstrate a ceiling-surface-to-work-surface illuminance ratio that does not exceed 10:1, provide on-site measurements or product data for finishes
8. To demonstrate that dimmable fixtures are used for 90% of the luminaires, provide cutsheets and lighting schedule
9. To demonstrate a CRI of 80 or higher for 100% of lamps, provide cutsheet
10. To demonstrate automated shade controls provide electrical switching plans or an electric schedule
11. To demonstrate automated or fixed shade control for top-lighting daylight systems provide electrical switching plans or an electric schedule.
