Note: This website is for the climate zone that includes North Central Texas such as the DFW or Denton area. Regardless of your climate zone, the first priority for green building or energy-efficient remodeling is to hire an energy consultant and a green builder who understand and use up-to-date green building practices for your area.
Air flow occurs only when thereis a difference between pressures. Air will flow from a region of high pressureto one of low pressure–the bigger the difference, the faster the flow. The negative and positive pressure differences of airin homes control its flow.
Ventilation is controlled airflow–the purposeful introduction of fresh air to the conditioned space in orderto ensure acceptable indoorair quality, control condensation, and reduce stuffiness and odors.
Infiltration is uncontrolled airleaking into the house, allowing too much air from outside in cold or hotweather and too little air in milder, warm weather when we need a breeze.
Exfiltration isuncontrolledair leaking out of the house.
Common air leaks in buildings cantake three forms:
Orifice Air Flow: Air flow where the air entry point and exit point are in a linear pathway; such as a crack between a window frame and the window opening.
Diffuse Air Flow: The passage of air through porous building materials such as fiberglass or uncoated concrete blocks.
Channel Air Flow: Air passing through openings in the building envelope where the air entry and exit points are not in a linear pathway. This often gives the air adequate time to cool below its dew point anddeposit moisture in the building envelope. Channel flow is typically found at the interface of dissimilar materials and is probably the most common and serious of allairleaks.
Air movement carries with it humidity, heat, pollutants, and sound. Controlling airflow across the enclosure, between zones, and from the distribution system to hollow partitions is necessary to build ahigh-performance, green home.Controlof air movement is essential to build an energy-efficient, healthy, comfortable, andsustainable home.
Air flow is also one of the mostimportant methods of heat transfer so the control of air flow is an importantcontrol of temperature in green homes.
Airflow also affects the oxygensupply & the spread of smoke and other toxic gases in a fire.
