Verification of energy savings
One of Building Systems Insight WattsGoingDown‘s clients has recently completely a lighting upgrade. There was a lot of discussion of the energy demand of the old lights, speculation about the energy demand of the proposed upgrade lights and how long it would take to break even on the upgrade.
WattsGoingDown BSI provides online access to real time energy use information for our clients and partners. In this case, verification is fairly simple but it illustrates the power of easily accessible, real time energy intelligence. Saturday morning, I grabbed as screen shot from BSI’s WattsGoingDown’s SaaS application. It shows energy savings of 50%. The upgrade reduced lights-on power from 32 kilowatts to 16 kilowatts. The upgrade happened over two different 2-day periods. Looking at the plot, it isn’t hard to tell when these upgrades were going on…

Doc,
Good post. I will investigate further. I am wondering how they can track down to an individual circuit with no additional equipment. Much of the equipment I am interested in is inside of one of our wastewater plants where we own the substation and purchase power at the highest possible voltage. I will likely publish something in my newsletter since we are always looking for ways to save energy in the water treatment biz.

WattsGoingDown recommends the WattNode from Continental Control Systems. We have a recommended hardware solution and can pre-program and configure the solution before sending it out. I plan to publish more information on the monitoring hardware here soon. WGD main business is the software layer for real time monitoring and analysis.
