What the data
actually says.
Written for people who have to make a decision about a real building, with real constraints, using numbers that came off real instruments. No listicles.
Turning HVAC into a revenue stream
Your chiller plant is the largest controllable load in the building and the most expensive thing in it to run. On roughly ten afternoons a year, it can be the opposite: an asset the grid will pay you to operate differently. The catch is that you have to be able to prove the reduction.
What a COP of 1.0 actually means
A coefficient of performance that low is not a bad day, a fouled tube bundle or a hot week. It is a plant moving water instead of moving heat — and the arithmetic that proves it fits on one line. Including the unit trap that makes a well-run plant look broken.
Why we adjust the baseline, not the results
A mild winter can manufacture savings that never happened, and a harsh one can bury savings that did. IPMVP Option C exists so that nobody takes credit for the weather — including us.
