OPTION 1. LIGHTING CONTROL 

OPTION 2. LIGHTING QUALITY

Any cost premium for this credit option will be very project specific, as it is a function of architectural and interior design, not scope. However, note that you must spend time and effort on good lighting design to provide good usability and comfort within the space.

In addition, energy-efficient lighting provides ROI in two concrete ways: by reducing direct energy used to light the space, and by reducing the heat output from light fixtures that increase the air conditioning loads and energy used to cool the space.
