Presentation Description Building high performance buildings, up to and including Passive House certified, means we need to ‘Build Airtight and Ventilate Right’. This presentation discusses the importance and benefits of properly balanced, filtered, continuous ventilation with heat recovery in high performance projects. By using mechanical heat recovery ventilation (HRV) and energy recovery ventilation (ERV) systems to provide oxygenated fresh air to occupants, we can control how much air is brought…

Passive House Air Quality
Passive House buildings rely on a constant supply of filtered fresh air, provided by a heat or energy recovery ventilator (HRV/ERV). Fresh air is delivered to the primary living areas, and stale air is exhausted from the “wet” areas—bathrooms, kitchens, and laundry rooms. (Note—the kitchen exhaust is not a replacement for a properly-sized range hood.) There are several important characteristics of this equipment: Fresh air is delivered and stale air…
