Measurement and Verification - The WegoWise M&V Report in Pictures
By: Kelly Kneeland
You might think you need incredibly specific
readings and intricate hardware attached to
your energy meters in order to complete
accurate and detailed measurement and
verification analysis: this is false! Keep clicking
to understand what’s behind the WegoWise
First: Monthly gas (or electric) usage and cost info for a multifamily residential building.
Second: Basic building information. Size, systems, and metering structure are the
keys to an accurate analysis.
Third: Monthly weather data. If your winter was an average of 5 degrees colder this year
than it was last year, you'd want to think about how your heating was affected by that.
Maybe you had a more efficient year, even though you used more energy. An open
source like degreedays.net can provide the data we need to determine that.
We have 3 simple datasets – utility usage,
building characteristics, and weather. Is there
really anything cool we can do with them?
Prepare to be amazed. With this info, we can
easily calculate a regression analysis to model
what the building’s energy would be had it not
received any upgrades.
Regression line of a user’s gas patterns based on all historical use.
We can then use this simple regression line to show what the difference
would be if the old efficiency levels were extended.
