Air Current Problems

1. Exhausted air creates a vacuum making it difficult to open doors when trying to enter room.
2. Exhausted air being replaced by makeup air creates a wind tunnel effect.
3. Stagnant air holds odors, dust, and other microscopic particles allowing them to settle on equipment. An oil-mist haze develops around machinery.

Winter Heating Problems

1. Warm air settles under ceiling forcing down colder air making work areas drafty and cold.
2. Heat consumption rises as workers turn up the thermostat to try to get warmer.
3. Open doors and bays cause cold air to be sucked into the main work area forcing any warm air available up to the ceiling.

Summer Cooling Problems

1. Open doors and bays suck in warm air from outside, mixing with colder air settled on floor level. Air conditioning cannot be balanced properly.
2. Air conditioning thermostat is turned down to compensate for incoming warm air causing a rise in electric costs. Stagnant air pockets develop.
3. Burner and oven efficiency drops. Burner units corrode and process fumes settle in work areas.
