Calculate planning BTU/h

Set the rate from your own load study or project criteria.

Planning capacity10,000BTU/h ·

Formula

Planning BTU/h = room area (ft²) × selected planning rate (BTU/h per ft²)

Variables

The rate is deliberately an input: it should come from project requirements or a documented load analysis, not an assumed universal value.

Example

500 ft² × 20 BTU/h per ft² = 10,000 BTU/h as a planning value.

FAQ

Can this replace Manual J?

No. DOE guidance recommends recognized load-calculation methods such as ACCA Manual J for proper equipment sizing.
