Model up to six chiller options across their expected lifetime: capital, energy, refrigerant leakage, embodied carbon and the cost of offsetting what is left, stress-tested over thousands of simulated futures. Adjust any assumption and every figure updates instantly.
Sunk capital is excluded, so every dollar and tonne shown against this baseline is attributable to the upgrade. The baseline is held at today's performance for the analysis period because that is how avoided energy is measured — not because the machine is expected to last that long. Most plant at this point is at or near end of life.
Name each option after the machine you are actually quoting and enter its real capacity, price and IPLV — those names and figures carry through to the report. The presets are illustrative starting points, not recommendations.
| Option | Capital | Energy saved | Year-1 saving | Simple payback | Discounted payback | Lifetime saving | Emissions avoided |
