Building Science for the Rest of Us
7 basic principles to make homes safe, durable, and energy efficient
A. Tamasin Sterner delivers seven basic principles to make homes safe, durable, and energy efficient in “Building Science for the Rest of Us.” The first principle is comfort, and there are four primary factors affecting human comfort: air temperature, relative humidity, radiant temperature, and air movement. Those four factors affect not only comfort but the efficiency and longevity of a home. Understanding that heat moves from warmer spaces to colder spaces and that moisture gravitates toward dry spaces, drive the need for sealing air leaks, using vapor barriers, and proper use of insulation. Any changes that are made in one area must be thought through in terms of how they may affect other areas of the house.
