One of our clients, who was experiencing a net loss of two-thirds of the outdoor air because of an inefficient ventilation delivery system, was able to erect a few sheet metal barriers in the system and double the local ventilation rate without increasing fan energy consumption.

In addition to any assumed infiltration, the standard prescribes the whole-house mechanical ventilation rate given by Equation 1:
Air emissions from power-ventilated buildings are calculated from: 1) ventilation rate, which varies by at least an order of magnitude; 2) inlet pollutant concentrations, which are affected by exhaust air re-entry and external sources; and 3) outlet pollutant concentrations, which are measured in a representative exhaust location among 4 to 75 fans.
Other factors, such as ventilation rate, temperature, and humidity can also impact indoor air quality.
