Video: Commissioning HVAC systems for sustainable indoor air quality

Learning objectives

• Recognize steps for sustainable indoor air quality-driven commissioning tests for existing buildings.
• Integrate emerging technologies and commissioning approaches into traditional commissioning approaches
• Strengthen the ability to perform field measurement and verification of HVAC system performance for sustainable indoor air quality
• Leverage sustainable indoor air quality-driven commissioning to develop alternative strategies beyond increasing outdoor air levels

Do the health and safety benefits of common IAQ strategies justify associated cost, energy, and carbon penalties? Do air cleaning and disinfection technologies offer better alternatives? This session will provide a framework for commissioning HVAC systems for sustainable IAQ, guidance for integrating emerging approaches and technologies with traditional commissioning services, customer case studies illustrating best practices, and ROI.

Building owners and operators have the unenviable job of figuring out how to respond to the growing demand for better indoor air quality (IAQ), which has been accelerated by the COVID-19 pandemic, while at the same time responding to expanding mandates to electrify and decarbonize buildings to address the climate crisis. Heating and cooling large volumes of outside air to maintain comfort while diluting indoor-generated contaminants like airborne pathogens and volatile organic compounds (VOCs) can be very energy intensive in hot and cold climates. Conditioning all of this outside air also makes it harder to implement net zero energy solutions due to larger heating and cooling loads. However, do the health and safety benefits of many common IAQ strategies justify the cost-, energy-, and carbon-penalties associated with increased outdoor air rates, increased filtration levels, and increased HVAC system run times? And are there alternative strategies that reduce the tension between IAQ and sustainability, particularly those making use of often-more energy efficient air cleaning and disinfection technologies? In recent years, emerging commissioning approaches have enhanced the ability of engineering professionals to address the above challenges and questions, and sharpen field measurement and verification of HVAC system performance leveraging science, technology, and data, including aerosol tracing technology, real-time IAQ sensors and monitors, and IoT-enabled building management systems. This session will provide: 1) a conceptual framework for commissioning HVAC systems for sustainable indoor air quality; 2) practical strategies for integrating emerging approaches and technologies with traditional commissioning services; and 3) applied case studies to illustrate the conceptual framework and integrated commissioning approach in action and highlight the safety, financial, and energy efficiency return on investment for real world clients.
