Zone Calculator
This calculator will convert the room btu totals from your heat loss / heat gain into cubic feet per minute of air (cfm) for each room.
Number of Zones
Will this calculation be done for a one zone or two zone system? 'Two zone' system refers to the use of motorized dampers. To zone with equipment, consider each area and piece of equipment a one zone system. For heat pumps and modulating furnaces, each zone should support 100% of the air flow, and thus be calculated as 1 zone. Click here for more zoning information.
