Integrated Daylighting Systems
Preliminary Technology Assessment
What is This Technology?
DALI enables individual control of fluorescent ballasts using fixture-mounted daylight and occupancy sensors. DALI defines light output for all levels of dimming signals, ensuring consistent dimming performance across multiple dimming ballasts, regardless of type or manufacturer.
Why is GSA Interested?
Measurement & Verification
The Green Proving Ground program has commissioned the Lawrence Berkeley National Laboratory to perform measurement and verification (M&V) on integrated daylighting systems at numerous test sites across the country.
