Pressure Control for Today’s High Performance Green Buildings
The control of building pressure is essential to maintain acceptable indoor air quality (IAQ), thermal comfort, and structural integrity. Negatively pressurized buildings result in the transport of untreated outdoor air into the building. this untreated outdoor air will result in the transport of dirt, dust and other contaminants; the transport of moisture in humid climates; mold growth; and more. In addition, improper building pressure may damage the building envelope.
