In this episode of the Building HVAC Science podcast, Eric Kaiser takes the lead in interviewing three guests from the ROCIS (Reducing Outdoor Contaminants in Indoor Spaces) initiative: Linda Wigington, Bill Collinge, and Rhett Major. Linda introduces ROCIS, sharing its 10-year mission to help participants monitor and improve indoor air quality, particularly in areas with poor outdoor air. The initiative, primarily focused in southwestern Pennsylvania, involves virtual cohorts where participants use low-cost monitors to track air quality and receive guidance to improve it.
Bill Collinge discusses the differences between low-cost and high-end air quality monitors, explaining how ROCIS focuses on measuring particles and carbon dioxide. He describes how the cohort process helps participants compare outdoor air quality with indoor conditions, assessing how well homes filter and ventilate air. Bill also highlights how data collected across multiple homes helps identify patterns and informs recommendations for improving air quality, while Rhett Major explains the process of air handler interventions. By testing static pressure and airflow in HVAC systems, Rhett helps participants optimize their systems to run more efficiently and reduce energy consumption while improving air quality.
The guests discuss key takeaways from the program, including the importance of filtration, proper HVAC system setup, and the potential health benefits of reducing particulate matter indoors. They emphasize the need for proper system commissioning and the challenges of engaging HVAC contractors in this work. In closing, the team shares their hopes to expand ROCIS principles and interventions beyond Pennsylvania and offer guidance to those interested in healthier, more energy-efficient homes.
