This course examines what makes a window truly sustainable. We discuss the important aspect of energy efficiency, but have deepened our study of sustainability to include a manufacturer’s attention to resource efficiency, to occupant health, and to durability. When all four factors are robustly addressed by a manufacturer, the windows and doors that company produces will more fully embrace the spirit of sustainability that green-leaning architects want for their buildings.

Learning Objectives

  • Discuss the factors that make windows energy efficient, and how energy efficient windows are tested and rated.
  • Define practices at window plant that reduce waste, and that use recycled or sustainable materials.
  • Identify how windows and doors can be manufactured and specified to have better impacts on the health of occupants.
  • Identify how windows and doors can contribute to certification through programs like LEED, NGBS, ILFI and other green building programs.
