Experiment to determine how long it takes for your space to heat up or cool down. You'll save money by only using your HVAC system when you need it. Manage the building envelope . Let in only the air you want, and don't let the tempered air escape. Draw in outside air.
Outside air is a natural and efficient coolant, especially at night.
Let in cool night air to pre-cool your building for the next day. To flush warm air out, vent the cool side of the building or operate attic vents and fans on that side. Adjust air duct registers. Adjust vents to manage the flow of tempered air and increase your employees' overall comfort level. Use exhaust fans sparingly.
