Design for passive solar winter benefits: A passive solar home is designed to admit and store energy from the sun in winter for solar heating. Air and moisture barriers and quality flashing are keys to slow thermal convection, reduce air leakage, and prevent moisture in walls that can cause mold and mildew. Although one does not always have complete control over the orientation of a building, especially in retrofit projects, it is still very important to consider which direction the building is facing and where the windows will be installed.
