Structural Beam Load Calculator vs HVAC Load Calculator

Two calculators for the same neighbourhood of questions. Here is what each measures, what you feed in, and where you'd reach for one over the other.

Civil

Structural Beam Load Calculator

Estimate the load-bearing stiffness of a simply supported structural beam based on its span, cross-section, and material. Use this when sizing floor joists, headers, or steel beams for construction projects.

Answers
Maximum Uniform Load (lbs/ft)
Inputs
Beam Length, Moment of Inertia, Elastic Modulus, Support Type
Construction

HVAC Load Calculator

Estimate the heating or cooling capacity (BTUs) your room needs based on size, ceiling height, insulation, and climate. Use this before sizing an air conditioner, heat pump, or furnace.

Answers
Required BTU/Hour (BTU/hr)
Inputs
Room Area, Ceiling Height, Insulation Level, Climate Zone, Windows/Sun Exposure
