I know the electrical power of all equipments, but how can I calculate the remaining electrical consumption (lighting, heating, air-conditioning)?
A fast way to get a rough idea of the needed electrical power (including the safety margin) is to double the total power of the oven line. You usually get a quite realistic figure. For a more precise calculation: – Air-conditioning: about 15 watts per cubic meter (look at the technical documentation for more precisions). – Lighting: about 20 watts per square meter. – Electrical consumptions of the heating system may strongly vary, depending on the building and the location of the ovens in your bakery (ovens are a very effective heating source!). – For safety reasons (tension variations and/or short-term expansions of your business), you should add at least a power of 30-40% to the theoretical total of needed electrical power.
