3 Home Ventilation Options to Keep You Cool in Monrovia
Adequate home ventilation has always been a major factor in keeping the house comfortable and the indoor environment fresh. Houses built before the 1970s got a lot more ventilation simply because residential construction standards permitted more cracks and gaps, and air exchange with the outdoors happened naturally. As energy efficiency became a greater priority, however, houses became more airtight and indoor air stagnated.
Home mechanical ventilation remains the simplest and most cost-efficient method of ensuring that living spaces remain comfortable and healthy. Here are three broad categories for using outdoor air to maintain indoor comfort.
Open Windows and Doors
Passive ventilation requires no fans, just natural air currents entering and exiting through open doors and windows. When outdoor temperatures permit, open doors or windows fully on the side of the home exposed to the breeze and partially on the opposite side. The difference between positive air pressure on the windward side of the house and lower pressure on the leeward side creates a continuous cross-flow of air through the interior, pulling in fresh air and exhausting indoor heat.
Air in motion promotes home ventilation. There’s no better way to keep indoor air moving than the gentle, energy-efficient effect of ceiling fans. They’re a time-tested way to promote indoor comfort and exploit the wind chill effect that makes a room with a current of moving air feel several degrees cooler than the same room with no air movement. In summer, set ceiling fan rotation in the reverse or counterclockwise direction to direct a continuous downward breeze.
A high-volume attic fan installed in the ceiling draws cool outdoor air into the home through open doors and windows and exhausts it through attic vents. This rapid influx flushes the house of warm, stagnant air and offers immediate refreshing ventilation, particularly on cool nights or mornings. For a 1,500 square foot residence, a whole-house attic fan will move about 6,000 cubic feet of air per minute through the indoor environment.
