Case Study: Adjusting the set-points reduced the HVAC run time by 20%
Energy Star states commercial buildings can trim their air conditioning cost by 12-15% just by raising their room temperature 3˚ during the summer. But how do you really know if you are saving money?
Our Client Success Managers review each site and all the equipment at the site. During a recent analysis, Joe noticed the kitchen compressor was running extremely long. Therefore, he suggested raising the temperature 2˚ to see if they could cut energy costs while keeping the kitchen at a comfortable temperature for staff.
This simple analysis cut the compressor usage by 20%, cutting compressor run time by almost 3 hours a day. While that does not seem like a lot, take a look at the graphs. Besides energy, this will reduce wear on the compressor and help elongate the life of the unit.
Original Graph – Target temperature of 73 degrees in the kitchen – Compressor run time of 13.1 hours (787 minutes) over a 24 hour period
After Adjustment – Target temperature raised to 75 degrees in the same kitchen – Compressor run time of 10.5 hours (630 minutes) over a 24 hour period. Savings of 20%.
