📄 Generate Word Report

Generates a complete .docx following the IAC insulation template - Q_u, Q_i, AES, ACS, implementation cost with payback.

∑ Formula Reference

Q_u = h × A × ΔT × H × RF / 10⁶

Q_i = A × ΔT × H × RF / (R_s+R_i) / 10⁶

AES = (Q_u − Q_i) / η

ACS = AES × R_Ga (gas)

IC = A × $/ft² + Labor hrs × $/hr

PBP = IC / ACS

h = 1.4 Btu/ft²·hr·°F (default bare steel).
R_s = 1/h = 0.7143. R_i from insulation table.
η = heating source efficiency.
