Audited planning profile

This shared daily profile applies a 3× editable baseline across 1 model period to the home heating and cooling compare model.

USE THIS PROFILE TO

Compare housing affordability, financing or ownership-cost scenarios on a consistent scale and horizon.

DECISION RULE

Use the difference between option A and option B; keep the scale and horizon identical for both. Define a consistent allocation rule so shared usage is not counted twice. Use a typical day and separately test peak or exceptional days.

NOT INCLUDED

Lender underwriting, local taxes, legal fees, insurance terms, maintenance shocks and future property values are not inferred.

VERIFY BEFORE ACTING

Reconcile the result with a lender quote, contract terms and a local closing-cost estimate.
