Electrical contractors know new doesn’t automatically mean better.
If a tool or technique works reasonably well, why risk the potential cost and disruption of switching to an unproven alternative, like energy retrofit software? Paper is cheap, and you already have an Excel license. Plus, any new software typically comes with a learning period (and maybe a little grumbling from employees.)
As it turns out though, energy retrofit software can quickly pay for itself, and then some—and in ways you might not have expected.
