In typical modern U.S. residences, about one-third of the HVAC energy consumption is due to infiltration. Another third is to ground-contact, and the remainder is to heat losses and gains through windows, walls, and other thermal loads. As such, reducing infiltration can yield significant energy savings, with rapid payback.
However, such spaces are not always fully occupied; in these cases, energy is wasted as the HVAC system processes more OA than is necessary for the space occupants.

Air conditioning myths persist because of parents wanting to keep the bills down. With expert help, we bust 12 common lies parents tell about air conditioning.
The result is either a positive or negative buoyancy force. The greater the thermal difference and the height of the structure, the greater the buoyancy force, and thus the stack effect. The stack effect can be useful to drive natural ventilation in certain climates, but in other circumstances may be a cause of unwanted air infiltration or fire ...
