There are a variety of factors that influence the environment within homes at any given time, including climate, building enclosure performance, and mechanical system operation. There are times when a specific system places this environment under conditions that are not ideal for occupants, including the operation of large kitchen range hoods and exhaust fans. This large exhaust systems (typically greater than 400 CFM) have the potential to substantially depressurize interior spaces. This webinar will take another look at residential makeup air systems, focusing on modern technologies and recent code requirements that dictate the design and construction of these systems.

Learning Objectives

  1. Understand the impact that large residential exhaust systems, including kitchen range hoods, can have on the interior environment and the health and safety of occupants.
  2. Analyze current code requirements in Pennsylvania, including updated language from the 2015 IRC, and the impact they have on the implementation of makeup air systems.
  3. Examine current equipment options for providing makeup air systems that help to keep interior building pressures at safe and appropriate levels.
  4. Discuss the challenges installers face when trying to incorporate makeup air systems into overall HVAC systems from a constructability and cost standpoint.
