For decades, the drive for energy efficiency took priority over indoor air quality (IAQ). With COVID, the pendulum swung in the direction of IAQ, but as we emerge from the pandemic and prepare to meet ever more stringent building performance standards, we need to design and operate buildings for both IAQ and efficiency. The question is how to solve for these seemingly contradictory goals given the “energy penalty” associated with higher ventilation rates. This session provides a pathway for balancing IAQ and energy efficiency using ASHRAE’s performance-based standard, the Indoor Air Quality Procedure (IAQP), with air scrubbing technology that saves energy by controlling contaminants of concern with lower ventilation rates.
- Assess how performance-based ventilation design can improve indoor air quality and save energy
- Describe how the use of air scrubbing technology improves ventilation design
- Clarify how the proposed design approach helps with LL97 compliance and equity
- Identify projects where the proposed design approach is appropriate
