C LIMATE C ORPS B AY A REA 2012 T RAINING T12 vs T8 Activity Activity Instructions : Break up into teams of 3-4, grab a flicker checker, and select a specific site to conduct a linear fluorescent light audit, specifically looking at existing T12/T8 lamps in the building. Use the worksheet provided to collect information on the study site’s existing lighting condition. Calculate the potential electricity, cost, and GHG savings associated with upgrading the existing lighting conditions, if an upgrade is needed.

Draw a floor plan of the study site as shown in the previous slide, and write down different light meter levels (foot-candles). Collect at least 6 light meter levels in different parts of the room. Based on the recommended lighting level, assess if there is too much/too little light in the study site, and what next steps you would recommend to the facilities staff to help them save energy.

Power drawn by a plug load while in operation What’s a phantom load? Aka energy vampires, standby loads U.S. consumption of phantom loads = electricity use of Greece, Peru, and Vietnam, combined. Phantom load on this printer is 2.8 watts. This translates into _______kWh a year.
