[Equest-users] Occupancy Lighting Sensor

[YinRic]

Thanks Nick, very helpful! It is indeed a LEED project...I will have a closer look at Table G3.2. Your comments on how to model more accurately is also valuable.

If you are looking at a LEED project, ASHRAE 90.1 dictates what percentage credit (from your lighting power densities) you can take for occupancy sensors, based on what type of occupancy you have, in Table G3.2.  
 
If you are looking to model more accurately (?) based on your project’s unique spatial occupancy patterns and switching configurations with the occupancy sensors (outside of a LEED project), then I believe you can create a custom schedule in eQuest for your lighting loads, adjusting the percentage of the maximum load hour by hour.

Hi, 
 
Does anyone know if it is possible to simulate occupancy lighting sensor in eQuest? We have a huge warehouse which is not regularly occupied. Occupancy lighting sensors are incorporated in the design. But I don't know how to simulate this...Maybe adjust the schedule in the design case, different from baseline case? 
 
Any comments are appreciated.
