Achieving good indoor air quality (IAQ) in nonresidential and low-rise residential buildings requires designers to understand and balance many HVAC system parameters. Following the ASHRAE standards that apply to ventilation, air movement, and exhausting of contaminants ensures that IAQ requirements will be met. A well-designed HVAC system must provide sufficient air flow, control moisture and contaminants in building assemblies and mechanical systems, limit contaminants from indoor and outdoor sources, meet system performance requirements, and minimize lifecycle costs.

Learning objectives:

  • The audience will understand the applicable codes: ASHRAE 62.1: Ventilation for Acceptable Indoor Air Quality and ASHRAE 62.2: Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings
  • Attendees will learn about optimizing air flow while identifying and minimizing air barriers and pressure boundaries
  • Viewers will understand how fresh air ventilation, air movement, and system air exhaust affect indoor air quality
  • Viewers will learn about designing high performance air systems that meet system performance requirements and provide system longevity.
