Stanford University needed to understand what is the impact of plugs and electronic appliances inside their 700 buildings on their building operations.
To get a glimpse into the black box of plugs, 12 interns spent 6 months using a customized app developed by Stanford IT to manually record what appliances were being used in about ⅓ of the campus buildings. The team had to then look up expected average power usage of each appliance from the manufacturer’s spec sheets to get a non-specific estimate of the impact of plugged appliances.
Stanford University instantly experienced a 17X faster and easier way to collect plug inventory data and at the same time, get real-time access to usage and utilization data.
Keewi has upgraded existing plugs at select Stanford buildings, including administrative buildings, classrooms, student dormitories, the alumni center and athletic facilities to collect high-frequency power signature data for each appliance. Based on the power signature data, Keewi’s advanced analytics platform has enabled the Stanford team to have real-time access to information about
what’s plugged in
how is being used
how much energy it’s drawing
No more manual inventorying with more than 34,000 hours of time savings in labor costs at scale!
Stanford has been using Keewi’s plug and occupant management technology to engage occupants and reduce their environmental footprint. With Keewi, they have been able to achieve a 21% reduction in electricity use of plugged appliances with a customer satisfaction score of 7.1 (on a scale of 1-10).
Manual space utilization measurements with clickers 4-5 times per day
Real-time space utilization information with workplace-level granularity
"Keewi has a great program for the reduction of electrical plug loads, that engages building occupants to manage their electrical use."
Electrical appliances were left on 24/7 even when unused
32% savings in plug load energy use in offices
50% higher energy use compared to ZNE building model
Removed operational uncertainty and identified energy hogs
