METRIX 4 ANSWERS TOUGH QUESTIONS Production Volume Weather
Obtaining funding for an energy project can be di?cult. So it’s important

upgrades and installation of other ECMs during the performance period
Imagine if performance period utility bills showed increased usage kWh such as lighting upgrades, load shedding, etc.
