Building owners, managers, and occupants are more aware than ever of the importance of indoor air quality (IAQ). At the same time, expectations for energy performance and carbon emissions reduction are rising, and myths of the tradeoff between energy efficiency and IAQ persist. However, IAQ is an outcome of properly designed, constructed, and functioning buildings, as are energy efficiency and occupant comfort, and commissioning is key in optimizing these synergistic outcomes. This webinar will discuss the role that commissioning providers (CxP) play in supporting good IAQ in buildings during the design, construction, and operation phases, from establishing IAQ criteria to identifying issues and guiding solutions.
