Energy-Efficient Windows for Residential Buildings
Mark P. Rossow, PhD, PE Retired
This six-hour online course provides information to help engineers, homeowners, builders, and designers select energy-efficient windows. Section 2 provides an overview of measuring window performance. Section 3 describes window technologies, including glazing types, low conductance spacers and gas fills, and frame types. Section 4 leads the user through a step-by-step window selection process involving codes, the ENERGY STAR program, and the use of tools such as the Efficient Windows Collaborative’s Window Selection Tool. In Section 5, the energy savings are shown for several window types in 16 cities representing the full range of U.S. climate zones. Savings are shown in the context of new and replacement windows. Section 5 also includes a discussion of window costs, life cycle cost issues, and other benefits. Section 6 addresses the impact of design conditions such as orientation, window area, and shading on performance, and Section 7 summarizes key issues in window installation.
This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
This course teaches the following specific knowledge and skills:
This course is intended for engineers, builders, homeowners, and designers concerned about saving energy in residential buildings.
Benefit to Attendees
A person completing this course will be able to select the type of energy-efficient windows most suitable for a given building site, type, and climate zone.
Windows are an important component of the energy performance of any house. They are also one of the more costly and multifaceted building products with a wide range of technology options.
This course is based on the DOE document, “Measure Guideline: Energy-Efficient Window Performance and Selection,” prepared by John Carmody and Kerry Haglund of the University of Minnesota under NREL Contract No. DE-AC36-08GO28308 (Subcontract No. KNDJ-0-40338-02), November, 2012.
