). These calculations required assumptions to generally be manufactured wherever info wasn't measured and thus the outputs really should be viewed as illustrative rather than complete. The calculations make use of the conventional equation [42] revealed in Equation (1) relating the overall ventilation amount, to the equilibrium indoor CO2 focus for any specified outdoor focus:
