    How Optimizing Fan Power Helped a Pac-12 School Save $100K Annually on Energy

    Our approach, which we call ‘Efficiency Production,’ is a long-term commitment. That means we don’t just drop in, offer advice and move along. We know that energy savings only persist when someone takes ownership for them. If energy savings aren’t measuring up, we cut a check to our clients. No matter how smart your projections, there’s always going to be efficiency drift over time.
