CS-2009 EAc5.1:Measurement and Verification—Base Building

Lighting measurement

good day, I have a project with 14 floors and our project scope is to control the hall and restroom lighting, we can measure and verify their savings. I have a doubt about what I need to measure, my proyect has identical floor between 3 floor to 13. Basements, 1,2 and 14 floors are different, so we need to measure each floor with a meter for each zone; or can I measure the total consumption by the halls and bathrooms the way that only use 2 meter to connect to the BMS.

In my experience how this is sub-metered depends on the electrical wiring design. If the lighting circuit for all the halls/restrooms are in a single panel box then you certainly could meter them together. Keep in mind the goal will be to gather the data needed to calibrate the model. So you will need to get the data for the total lighting for the building and verify the lighting savings. You do not have to sub-meter by specific area or strategy to show the savings.
