Lunch & Learn: Ensuring good indoor air quality
Part of the Future Homes Standard Essentials Series
Date / Time:
Friday 22 May 2026, 1-2PM.
What is the webinar about?
Achieving good indoor air quality is an essential part of delivering high-quality homes. As homes become more energy efficient and more airtight, ventilation plays an increasingly critical role in maintaining healthy indoor conditions.
Ventilation should be treated in the same way as structure, fire safety, fabric performance and heating systems: as a critical building service that requires clear design specification, coordinated delivery and verification. Regulatory compliance is the baseline, but quality delivery requires attention to process as well as specification.
Join a panel of the UK’s leading ventilation experts as they explore the key elements that are critical to success. Plus learn how these insights have been combined into our new guide designed to help homebuilders deliver good indoor air quality for their customers.
