The purpose of this lesson is to introduce the concept of fenestration, and to explore factors that impact window’s thermal and optical performance through a series of lectures and exercises.
Objectives
After this lesson, students will…
- Describe and discuss the components of a typical insulated glazing system and common variations
- Describe and discuss the heat transfer mechanisms that influence glazing heat/gain loss and window thermal performance
- Describe and discuss factors that effect window optical performance
- Use detailed building energy modeling to compare and contrast the performance of several glazing options.
