The U.S. Department of Energy recognizes the enormous potential that exists for improving the energy efficiency, safety and comfort of existing American homes. Air and water vapor are transported into and within single-family homes as a result of pathways and driving forces. Without pathways, no air or water vapor transport will occur. Homes always have pathways and driving forces. This book focuses on managing the driving forces that move air and water vapor across the building envelope and also identifies ways to make homes more comfortable, more energy efficient, and healthier to live in.
