Sustainability in the laundry room

This article is part two in a three-part series on energy management. Look to Tuesday's tech news for the last part.

Advancements in washer and dryer controls are helping energy management in the laundry room, said Bill Brooks, national sales manager at commercial laundry equipment manufacturer UniMac.

“Knowing how much water, electricity and time you’re using on these cycles and being able to get your head around that is important,” Brooks said. While a 10 minute change in a cycle or a water level setting are not things a GM would usually be aware of, being able to track them allows GMs to make changes to control energy costs.

“I think, with some of the early sustainability programs, there was such a high cost to trying to be good stewards of energy, that it never produced a return,” said Brooks. “But now as long was we can manufacture a product where there’s an ROI I think it’s going to continue to grow, and the beauty of it is, with controls, you can always prove it.”

Other recent developments in sustainable laundry equipment include moisture sensing on a tumbler dryer, which allows a dryer to stop when it senses a certain moisture level and avoid wasting energy on overdrying, Brooks said.
Another older but popular solution is hi-G washing machines. By increasing the G-force at which the machines spin from 100Gs to 400Gs, hoteliers can cut the amount of water in a wet load of laundry from 100 percent of the load’s dry weight to 60 percent, Brooks said. That means the dryer has to burn less energy to dry the load.
