[Equest-users] Modeling Office lighting occupancy

[Allen Butler]

This is correct; a 10% LPD savings in each space with occupancy sensors
is the proper procedure. Regarding changes in occupancy scheduling to
model occupancy sensors, while this used to be acceptable for LEED I
have been called out on it by LEED reviewers and told I had to do the
10% LPD space reduction so I would avoid changing schedules to model
occupancy sensors.

I think according to appendix g,Table G 3.2, you can Take up to 10% for
it in spaces that have occ sensors (15% for buildings less than 5000
ft2). I think LEED will also accept differing schedules if they are
reasonable. You need to document this.

I don't see any method for modeling occupancy sensors for overhead
ceiling lighting in an office environment.  Does anyone know the proper
procedure?  Do I change the ratios in the lighting schedule and if so
how much is acceptable for LEED projects?
Thanks,
