If you wanna lower your spiking cost get a control system.
You waste a ton of energy starting a building that hasn't had air to it for over 12 hours.
Instead, a control system will have unoccupied times where instead of allowing the building to get whatever temp it does naturally, you can set the unoccupied times to let the building get no higher then 85°F(which is a bit higher then I like).
Then instead of turning everything on in the morning you can stage the buildings cooling. Turn this area, on then this one, then this one.
You slowly cool down sections at a time. This will help prevent spiking AND help the longevity of your chiller. Plus it will lower your electric bill because instead of trying to cool 95°F air and 70% Humidity to 72°F you will be cooling 85°F air with 55% humidity.
If you're too "open" minded, your brains will fall out.
Artificial intelligence is no match for natural stupidity.
