Construction calculatorContractor Building Heating Load Calculator
Calculate building heating load for a contractor construction scenario using clearly labelled project inputs.
Calculation explainedHow this result was calculated
The formula, your substituted values, and the evaluated result are shown below.
Formula: uValue * envelopeArea * temperatureDifference + ventilationLoss. Keep every input in the stated units. This result is a quantity-planning estimate; verify site measurements, waste factors, product yields, supplier data, applicable codes, and professional design requirements before construction.
