It is very difficult for humans to detect low levels of contaminants in their air, even when they represent a health hazard. Health Canada recommendations for optimum indoor air quality В© Health Canada To remove the excess humidity generated by normal human activity in order to ensure building durability and efficiency in heating, and to help prevent mold & mildew in homes.(Which is why choosing formaldehyde-free kitchen cabinets is recommended.) To remove contaminants вЂ“ because along with the toxins emitted by the human body (ammonia, benzene, carbon monoxide and methane to name but a few), toxic chemicals like formaldehyde in building materials and furnishings continue to off-gas for many years after installation.In a reasonably airtight home with no ventilation you would feel the effects of that in quite a short time. To provide oxygen for occupants since people deplete oxygen as they breath.

Nowadays, in the name of energy efficiency, houses are built to much higher standards of air tightnessВ and building code all across North America is being updated to reflect this, so mechanical ventilation systems are essential to maintain healthy indoor air quality for the following reasons: In a cold climate zone, it meant that cold, dry winter air would need to be warmed as well as humidified having found it's wayВ into a house - otherwise known as drafts, while hot and humid air would enter in the summer whether you wanted it or not.

These houses were said to 'breathe', but that would be like breathing through your skin instead of through your nose. Up until the last few decades, houses were so leaky to air infiltration that sufficient cold dry air seeped in to meet the needs of occupants, and ensure homes had no moisture damage. In an effort to clear that up, we will first explore why ventilation is so crucial, then explain the options and their best applications. Energy recovery from exhaust air is becoming common place in cold regions, and two types of equipment can do this - an HRV (Heat Recovery Ventilation) and an ERV (Energy Recovery Ventilation.)Д«oth HRVs and ERVs are somewhat new to mainstream home construction, and can often be confused. How much fresh air is required in homes and the best way to provide it are important issues.

How to choose between an HRV and an ERV?.

What is the difference between an ERV and an HRV?.

How much fresh air comes in through the building envelope?.

This makes mechanical ventilation essential in these high performance home by installing either HRV or ERV Ventilation Exchanger Systems.

Buildings and houses are no longer constructed leaking heat and moist air the way they used to be we now build them as airtight as we can, especially Passive House or LEED certified homes. Our home comfort specialists can perform a thorough inspection of your home and present you with some options that will work best for your indoor climate.All homes need ventilation, whether natural or mechanical with an ERV or HRV system. But for homes that are too dry in the winter, an ERV will make more sense. For homes that are humid in winter, we recommend an HRV. So which one should you choose: an HRV or an ERV?В It all depends on your homeвЂ™s environment. This is a huge help to your air conditioner in the summer. This helps keep your home at optimal humidity levels in each season. What is the Difference Between HRV and ERV?ДЄn energy recovery ventilator (ERV) is quite similar to an HRV, but it will also transfer humidity. While an HRV is mainly used for fresh air, it also does a great job of keeping your home comfortable all year round. In the summer, the process is reversed so that your home stays cool. This transfers the heat from your stale outgoing air to the fresh, incoming air. How Does an HRV System Work?ДЄn HRV has a heat exchange core. With an HRV, youвЂ™ll breathe healthier air all year round without sacrificing warmth or the money it costs to heat your home in the first place.
