Did you know that ventilation is a key to keeping the chemistry and microbiology of your home’s air healthy? Home performance expert Corbett Lunsford reveals how proper ventilation can counter everyday activities like cooking and cleaning that generate unwanted particles and chemicals. You’ll learn the five key factors of ventilation, the rules for controlling indoor chemistry, and why simply cracking a window won’t solve your air quality problems. Corbett explains how to optimize your home’s exhaust systems, avoid common chemical accelerators, and balance your system with the right mix of dilution air, intake placement, and make up air. He also shows why regional radon maps can’t be trusted and how to protect your family. Packed with practical insights and real examples from his own high-performance home, this class will equip you to design a ventilation strategy that safeguards your health, protects your home, and keeps your air truly clean.
In this mini class, you’ll learn:
