Gone are the days when buying a newer home in Canada meant you’d be dealing with a draft under the doors and windows that let some of the outside air in. Today’s homes are built better than they’ve ever been before and while that means lower energy costs for the average Canadian, there’s also an need for more ventilation to allow for more fresh air inside our new, better built homes. Does the air inside seem stuffy when you first come in from outside? Is there a distinctive odour? These are just two of the signs that indicate you might need to increase the ventilation in your home, not only to make the atmosphere more pleasant, but to ensure the air you and your family breathe is healthy. There are several ways to increase this necessary ventilation. Remember, recent studies have shown that air exchange rates below 0.3 air changes per hour are common, which is the benchmark for acceptable quality indoors. The need for some kind of mechanical air exchange in the house is clear and ducted air moving equipment is a great way to accomplish this. At the bottom of the scale are bathroom fans that exhaust to the outside and then furnace fans that can aid in the exchange of older air for new. The latest innovation is called the Heat Recovery Ventilator (HRV). These supply the necessary ventilation without a large increase in energy costs. As well as supplying fresh air for the inside, they can preheat the incoming air and save up to 60 – 80 per cent of the heat that would otherwise have been lost. You can either use the existing furnace ductwork and have the furnace fan on, or install separate ductwork for the HRV that also has its own fan motor.
