Install electric ventilators and attic fans which remove hot air from an attic. Floor joists below kneewall with no blocking. They have thermostats that turn the fan on at a recommended preset temperature of 100 110 degrees. Hot or cold attic air can go right under the floor of the adjoining conditioned space.

It is placed at the highest point of your roof so that the hot air rises to get out. A powerful fan draws cooler early morning and evening air through open doors and windows and forces it up through the attic and out the roof vents. This type of vent runs along the entire ridge of your roof. If your house is too cold or too hot despite the furnace or air conditioner constantly running you may begin to wonder what s going on.

Alternatively install passive vents such as gable soffit and ridge vents which are openings in the roof that allow hot air to escape. If attic air can reach the drywall there s little resistance to heat flow between the attic and conditioned space. I have large attic with ridge vents and screened vents at either end of the attic to maintain air flow. Energy vanguard figure 5.

Hot air exhaust vents located at the peak of the roof allow hot air to escape. Can i put a small swamp cooler or ventless a c unit up there to cool it only to use while i am in my shop maybe an hour or two a couple times a week. The idea behind them is simple.
