Spring Quarter is already in full swing and our campaign to reduce elevator usage and encourage taking the stairs is heating up. In order to evaluate elevator energy consumption in the Mathematical Sciences building, we have placed a sensor inside to track the number of trips taken. The results are mind-blowing!
In our observations, the elevator takes 70 trips per hour, on average (determined by the number of door openings). Since each new trip consumes roughly 19 watt-hours, a total of 1330 watt-hours of energy is consumed per hour. Over a year, the elevator will consume about 3000 kWh!
Don’t forget, we are only measuring one elevator. Can you imagine the potential money and energy savings to be had by taking just a flight of stairs instead of the elevator? Did I mention the various health and environmental benefits of taking the stairs as well? Now put your thoughts to action: take the stairs instead of the elevator the next time!
