In many climate zones, the heating and cooling of outside air (OA) is one of the largest energy loads and contributors to building emissions. Traditional commercial HVAC designs based on the Ventilation Rate Procedure (VRP) rely on large volumes of outside air to maintain acceptable indoor air quality, often resulting in oversized HVAC equipment and wasted energy. Adding to this, good indoor air quality is no longer just a matter of meeting code but is now seen as a necessity for business continuity, improved learning outcomes, and employee productivity. In this course, we will examine ASHRAE Standard 62.1, a recognized standard for nonresidential ventilation system design, and its Indoor Air Quality Procedure (IAQP), which allows for the use of air cleaning technology to offset outside air for a more efficient ventilation system design. We will review the requirements and calculations for this procedure, showing the impact on indoor air quality and energy use, and present a number of case studies. We will also show how IAQP used with air cleaning can help achieve LEED® v4 BD+C: New Construction and O+M: Existing Buildings and WELL v2™ certification.
