Welcome to the class! In this course intended for homeowners, you'll learn how to design and build a truly healthy, resilient home—one that goes far beyond code and surface-level finishes. Most homes today are prone to mold, poor indoor air quality, and other environmental hazards because of outdated building practices that fail to account for modern challenges like energy efficiency, tighter envelopes, and changing materials. You'll explore why building codes don't guarantee health, why tract and spec homes often fall short, and what it takes to create a custom high-performance home that supports wellness. Using a science-based approach grounded in building physics, this course will guide you through key principles like building tight, insulating and ventilating right, and ensuring assemblies can dry. Along the way, you'll learn to prevent mold, reduce VOCs and EMFs, and advocate for your own project—even if you're new to construction. Let's get started building smarter, healthier homes.
