It has become very important for architects to understand how to choose a sustainable window and window frame system that will promote comfort, energy efficiency, durability, and longevity through quality construction. Using new technology and material components windows can be built with long lasting durability and satisfy sustainable design concepts by promoting healthy living conditions. Use of natural and mechanical ventilation and increased daylight help improve indoor air quality while lowering heating and cooling costs for the occupants. The use of building information modeling and energy modeling combined with using Energy Star rated products encourage sustainable green building practices for homes and buildings reducing energy and contribute to a sustainable environment. While windows improve the comfort indoors and beauty to the exterior design of a home; use of energy efficient windows can contribute toward points in LEED for Homes credit categories.
