The student will understand the importance of using different types of glass in order to increase energy efficiency. Explain heat losses and gains through glass. Describe types of glass and windows that can increase a home's energy efficiency.
Many people enjoy the windows on their home for the lighting, ventilation, and view they provide.
They do not realize that having many windows also has disadvantages. Up to 15 times more heat is lost or gained through windows as is lost or gained through an equal area of wall space. There are ways, however, to increase the energy efficiency of windows. Multiple Glazings - One important way to decrease energy loss through windows is to increase the number of panes, or glazings. A single-paned, untreated window unit is very energy inefficient.
