Automatic high-speed doors, often used in cold storage, are more efficient than strip curtains, PVC fabric doors or roller shutters. The durable construction provides a higher operating speed and they can sustain a higher number of opening and closing cycles. Automatic high-speed doors also require lower maintenance and repair costs. Depending on the use, horizontal or vertical doors are available.
Automatic high-speed doors can save energy by decreasing the amount of time a door will remain open compared to a traditional warehouse door. Traditional warehouse doors are generally left open for longer periods of time than necessary since it takes extra time to open and close these doors manually.
The savings potential for automatic high-speed doors is variable and depends upon its location, temperature differences between the two spaces, and time left open.
An incentive of $8,000 per door for freezer to dock doors and $4,000 for freezer to refrigerator doors is available for retrofits and new construction through Idaho Power’s Commercial and Industrial Energy Efficiency Program.
Simple payback will vary based upon how many hours the door stayed open before retrofit. On average, payback after incentive will vary between six to eight years.
