Daylight harvesting on a floor of building model in eQUEST

I have a three floor building model in eQUEST. To reduce lighting energy consumption of building, I have daylight set to "ON" for the second floor of the building and I got following results when I use Jaipur, India weather file (.BIN)

eQuest Results

  1. lighting energy consumption decreases which makes sense
  2. Why does HVAC (cooling) and fan energy consumption increase?

Moreover, I am getting proper energy consumption reduction when I use weather file of Atlanta for same building model.
