Solution at a Glance:
Small Changes to Steam Room Operations Garner Big Energy Savings
Life Time Fitness operates over 124 health clubs in the United States and Canada. During an energy audit of its Chanhassen, MN facility, the company determined that the men’s and women’s steam rooms constituted 13% of the peak load for the building, where both steam rooms ran constantly.
To address energy use, the LifeTime energy manager tested two changes. First, to cut down on peak demand, a relay was installed between the men’s and women’s steam rooms so that they would not initiate the heating system at the same time. Next, to cut down on the run-time of the steam rooms, a start button and timer were installed so that the rooms only operates when occupied.
As a result of these two upgrades, Life Time reduced average peak demand by 25.5 kW for the Chanhassen Club, saving $5,000 annually in electricity costs. Additionally, the retrofit had two unexpected benefits:
- Better control the steam and humidity in the area around the steam rooms;
- Reduced use of costly eucalyptus oil diffused while steam rooms are operating.
Life Time Fitness is implementing this solution across their full portfolio of existing clubs and into the design for new facilities.
