As homes continue to become more efficient, specifically related to envelope airtightness, a greater emphasis has been placed on indoor air quality (IAQ). Mechanical ventilation systems are key to ensuring proper IAQ in new homes. For new construction, builders often debate the merits of readily available systems and strategies. This session will focus on balanced ventilation systems, specifically heat recovery ventilators (HRVs) and energy recovery ventilators (ERVs). The focus of this session will include the common benefits to builders and occupants in terms of performance and IAQ as well as the challenges of system complexity and cost.

Learning Objectives

  1. Understand the code provisions related to mechanical ventilation in the 2018 International Residential Code and how they impact the selection of ventilation strategies.
  2. Examine currently available equipment and system options that builders may consider when providing homeowners with a well-designed strategy.
  3. Discuss the benefits and challenges of common systems, including installation, cost, complexity, and performance.
  4. Identify opportunities for builders to utilize ventilation strategies and systems as selling points to potential clients.
