How to select residential windows for energy efficiency

Friday, July 29th, 2011

A US government independent report for consumers on how to select Windows for Energy Efficiency is a timeless reference when you are considering new windows for your home. New window technologies have increased energy benefits and comfort, and have provided more practical options for consumers. This selection guide will help homeowners, architects, and builders take advantage of the expanding window market. The guide contains three sections: an explanation of energy-related window characteristics, a discussion of window energy performance ratings, and a convenient checklist for window selection.

  • Window Energy Rating and Labeling
  • Window Checklist
  • Window Energy Glossary

Selecting the right window for a specific home invariably requires tradeoffs between different energy performance features, and with other non-energy issues. An understanding of some basic energy concepts is therefore essential to choosing appropriate windows and skylights. Three major types of energy flow occur through windows: (1) non-solar heat losses and gains in the form of conduction, convection, and radiation; (2) solar heat gains in the form of radiation; and (3) airflow, both intentional (ventilation) and unintentional.

While technology has improved since this report was written, it’s still recommended reading to educate yourself before meeting with a replacement windows contractor.
