eone told him to add a heat recovery filntilation (HRV) system. To begin with, Walker was simply erested in achieving proper air circuâ€" ion in his new airtight home, but he on realized that the constant exchange fresh air was making a difference to acey‘s allergies. He noticed that enever she entered the house, she perienced fewer allergic symptoms. Not only was the HRV ensuring esh, filtered air, it was also eliminating door pollutants caused by building L_(‘)ducts, furniture, carpets, and animals. e HRV was giving the family the ility to control their indoor air quality. Walker has just put his house on the arket and is thinking of buying an Ider home. "The first renovation I‘m ing to do is upgrade the ventilation [')stem to an HRV," he says. â€" Heat recovery systems exhaust stale side air while bringing in equal ounts of fresh outside air at the same me, with one complete exchange ccurring every three hours. However, nlike ordinary ventilation systems, [RVs allow for the exchange of heat nergy between the ingoing and outgoâ€" ig air streams.

This process is reversed in warmer weather. While much attention has been given to outdoor air pollution in recent years, far less has been paid to indoor air qualiâ€" ty. Jean Poisson, Product Manager at Venmar Ventilation, manufacturers of the HRV that the Walker family installed, says indoor air quality can actually be much worse than outdoor air quality. "If your house is less than 20 years old, it‘s likely to be virtually airtight," he says. Poisson attributes this phenomâ€" enon to the energy crisis of the midâ€" 1970s. But while energy consumption and waste are declining, poor indoor air quality is on the rise.

For example, there are thousands of chemicals that are known to be used in the average home. Toxins given off by glues, cleaners, paints, sprays, and solâ€" vents are of particular concern. New homes also have high levels of formaldehyde from cupboards and other material glued together with formaldeâ€" hydeâ€"based glues. These tend to be conâ€" centrated at floor level, where children play. Stale air from tobacco smoke, cooking, and even pets, can all conâ€" tribute to poor air quality, and carpets become breeding grounds for dust and airborne bacteria. .

OLD WORLD STONE 1151 Heritage Rd., Burlington West of Appleby Ln., off North Service Rd. LAWN CARE MAINTENANCE In addition to controlling the flow of fresh air and the elimination of polluâ€" tants, HRVs play an important role in minimizing excess humidity in airtight homes. New homes often give off moisâ€" ture for up to two years and biological contaminants, like dust mites and molds, thrive in this environment. Owners of Râ€"2â€"000 homes, where HRV systems are mandatory, can attest to the health benefits of controlled humidity levels. In 1993, Ontario changed its buildâ€" ing code to deal with the challenges of airtight homes and air quality. Mechanical ventilation is now required in every new home and HRVs are mandatory in those with gas furnaces using standard chimneys, wood burning fireplaces, or electric heat. Some houses, however, are still built with exhaust fans and rely solely on the likelihood of structural air leaks to bring in the fresh air. According to Poisson, this is still not enough. Homeowners have no control over the quality and quantity of incomâ€" ing air as it is not filtered. They are also at the mercy of family or guests to turn on the exhaust fans, which are usually noisy. Poisson urges all those interested in buying a new home to ask the builder exactly what type of ventilation system is in place.
