As part of our work toward Advanced Lighting Control Systems (ALCS) incentive programs, quantifying the savings from ALCS has emerged as one of the biggest hurdles in adoption. In particular, estimating and verifying savings from daylight harvesting is challenging because savings are highly dependent on orientation, exterior obstructions, weather conditions as well as occupant behavior (mainly the intermittent use of blinds/shades on windows by occupants).

To overcome this challenge, we propose developing a simplified calculation method for estimation of savings from highly variable advanced lighting control systems for use in utility incentive programs.
