As a home performance provider, you have an opportunity to make the indoor air quality (IAQ) better than you found it. At a minimum, you don’t want to make things worse. Mechanical ventilation with filtration offers a tool to make this happen. This session will begin by summarizing indoor air hazards of concern, their sources, and the relationship between tighter envelopes and IAQ. The majority of the session will discuss how to address IAQ with ventilation/filtration. Topics will include addressing sources with spot/local ventilation; the benefits of continuous, whole dwelling unit ventilation (DUV); and the pros and cons of the different DUV approaches, including smart ventilation. The session will conclude with options for installing heat and energy recovery ventilators (HRVs & ERVs) for DUV.

Learning Objectives:

By attending this session, attendees will:
  • Recognize the main indoor air quality (IAQ) issues of concern and their sources
  • Understand the relationship between tighter envelopes and IAQ and how to address indoor sources of hazards
  • Describe the pros and cons of the different whole dwelling unit ventilation approaches, and where appropriate, understand how to choose and install heat/energy recovery ventilators (HRV/ERV)
