The following case study reveals the savings results for a Company Operations Complex in Kyogamiska, Japan after an Intelli-Hood® installation. Intelli-Hood® is a controls system that controls the ventilation fan speed, depending on the current conditions of the kitchen hoods. Temperature and optic sensors are used to detect heat and steam, and these sensors will change the fan speed accordingly. The study shows the cost benefits of an Intelli-Hood® installation as well as the key performance results.
The graph below, Figure A, shows the average fan speed for two exhaust fans over the course of six days. The dips in the chart represent times when the fans have slowed, and the spikes represent when the fans are operating at a faster speed. The fan speed varies slightly which means the fans are running more efficiently. The average fan speed for these exhausts was 61%.
In the chart below, Figure B, the facility’s annual energy costs are compared to their net energy costs. After installing Intelli-Hood®, this complex operates at $17,840 on average for their utility costs, with annual savings of $20,525. Which is a 53% reduction compared to the utility costs before Intelli-Hood®.
