AffordabilityUpgrading your ventilation could be as simple as replacing your bathroom fan and following some guidelines for good air circulation practices.
Cost savingsWhile mechanical ventilation does require energy, it is likely to save you money down the road. A poorly ventilated house is prone to rot and the occupants are more likely to suffer from allergies and other respiratory ailments. In addition, it takes more energy to heat wet air.
Health & comfortFor a healthy and comfortable indoor environment, air needs to circulate throughout the living space and be exchanged with fresh outside air. Proper ventilation can reduce mold, lessen the risk of carbon monoxide build-up and allow for energy-efficient air circulation.
Environmental considerationsUse a timer or dehumidistat with your fan to maximize energy efficiency by turning the fan on when it needs to be, but off when it doesn't.
What you need to know
FAQCan I just open a window to circulate fresh air?
Mechanical ventilation is far more efficient than opening windows and doors, and works well in all seasons. In fact, year-round energy use in more temperate parts of B.C. is often the same as that in colder places because of people opening windows and doors for fresh air in the shoulder seasons and then having to heat their space back up in the evenings.
Our house is drafty, would that provide enough air circulation?
Drafts are not a healthy or efficient form of ventilation. The air exchange can't be controlled and they are strongest when the difference between the inside and outside air is high. That means on cold nights, you are likely to feel a cold breeze coming into your warm house. Cold drafts can make rooms feel colder than it is and lead to inefficient heating and discomfort. During the shoulder seasons, when indoor and outside temperatures are more similar, you are likely to get very little air exchange.
