This week we welcome Marwa Zaatari, PhD and Christian Weeks to discuss a new document on How to Achieve Sustainable Indoor Air Quality: A Roadmap to Simultaneously Improving Indoor Air Quality & Meeting Building Decarbonization and Climate Resiliency Goals. The document was a collaboration between a group of industry companies that want to promote a layered, system-level “Clean First” approach which they feel is the key to the low-energy, high-IAQ, climate resilient buildings of the future.
