Poor heat and moisture management are the primary threats to durable, healthy, and comfortable housing. Essential Building Science offers a visually driven introduction to the fundamental principles of building physics for residential construction, aiming to equip readers with the knowledge needed for high-performance design. The book is divided into two parts: the first establishes the rationale for high-performance design and covers core concepts like thermal dynamics, moisture transfer, and hygro-thermal dynamics, including vapor drive and condensation. The second part focuses on developing critical thinking skills for a whole-systems approach to building, enabling the creation of effective thermal and moisture control strategies applicable to diverse designs.

The book is structured to provide accessible knowledge on building science, particularly focusing on energy and moisture management in high-performance house design. Its approach emphasizes visual learning and practical application, making complex physics understandable for a range of readers from professionals to DIY enthusiasts. The inclusion of case studies across different climates aims to demonstrate real-world problem-solving and the effectiveness of good building science principles. The content suggests a focus on practical, actionable insights for creating better buildings.
