Inquiry

We currently have accent lightings that are not fully shielded accenting statues on the crown of our building. These lights are turned on for an average of six hours per night, fluctuating depending on the time of year. The current lights are 120W halogen bulbs. Per the reference guide, these would have to be fully shielded if we were to qualify for SS 8. We are proposing a project to remove these lights and replace them with dramatically more efficient LED lights that will be well under 50W, reducing the energy usage by an estimated 500%. We want to confirm the exclusion in Option B relating to fully shielded fixtures listed for 50W and under exterior lights on page 108 in the reference guide to make sure we are eligible for SS 8 on this project. By doing this, all exterior lights above 50W will be shielded and we will have a marquee project utilizing a new technology that will be presented to the building tenants as part of a tenant education program highlighting our sustainable technology.
