Negative pressure systems work by forcing air outside from the building, so the indoor air pressure is lowered, then there is a negative-pressure zone and the air outdoor will flow into the house for the air pressure difference. Reduced fan efficiency is allowed for the unavoidable dust accumulation on fan blades. At low air flow rates, negative pressure systems will not provide uniform air distribution. There are heat recovery systems which are mostly used in modern commercial type and big residential buildings, available to capture heat from the air that is being exhausted to the atmosphere.
