📄 Generate Word Report

Generates a complete .docx with degree-hour analysis, EUN, ES, and cost savings - for heating, cooling, or both seasons.

∑ Formula Reference
DH = DD × Unocc. hrs/day
ES = ((DH_cur − DH_prop) / DH_cur) × EUN
CS = ES × Rate
DH = degree-hours (°F·hr/yr).
DD = degree-days from weather data.
EUN = energy during unoccupied hours.
Heating: MMBtu saved, Cooling: kWh saved.
