About CWM Energy

CWM Energy was founded on a simple idea: the tools and strategies used to optimize industrial energy systems can be just as powerful in your home.

We're passionate about energy efficiency — not as an abstract environmental goal, but as a concrete, measurable path to lower bills and a smaller footprint. Every calculator on this site uses established Canadian methodology (NRCan, NBCC) to give you numbers you can trust, not rough guesses.

Sustainability doesn't mean doing less. It means doing better.
