Climate Trend Estimator

A long-range "what if the climate keeps warming" planning sketch. You give it an assumed warming rate and how much your cooling bill rises per degree, and it draws a straight line out over your planning horizon to estimate the extra cooling cost and how heating/cooling demand shifts. "HDD" (Heating Degree Days) and "CDD" (Cooling Degree Days) are standard measures of how much heating or cooling a location needs in a year — more CDD means more air-conditioning load. The warming and cost numbers are assumptions YOU enter, not measured regional climate data.

For multi-year capital planning — deciding whether a facility's HVAC needs headroom for a hotter future, or building a rough cost case for a 10–20 year horizon. It is facility-level and crop-agnostic. Because the coefficients are your own guesses, it is only as good as the assumptions; use published regional warming rates if you have them.

Projected Temp Increase and Additional Cooling Cost/yr are just your warming assumption multiplied out linearly, so the output moves one-for-one with your inputs — change the warming rate and watch it scale. Rising CDD with falling HDD means your future is more cooling-bound (relevant in warm climates); the reverse matters in cold ones. Treat every number as directional. To turn a projected cost into equipment sizing, feed a hotter design temperature into the Thermal Management or MEP tool.
