The amount of outdoor air provided throughout the building exceeded the minimum requirements by 60%. International Mechanical Code (IMC) for commercial buildings specifically include provisions for ventilation and related issues and are commonly used by states and communities, and are included. Mechanical ventilation systems may include supply fans (which push outdoor air into a building), exhaust fans (which draw air out of building and thereby cause equal ventilation flow into a building), or a combination of both.
