Understanding How Window Energy Efficiency is Measured

When shopping for energy-efficient windows, understanding how their energy performance is measured can help you make the most informed decision. Several specific criteria are used to assess and rate a window’s energy efficiency. Here’s a closer look at the metrics you should be aware of:

1. U-Factor

The U-factor measures how well a window prevents heat from escaping. It rates the window’s insulating properties. A lower U-factor means the window has a greater resistance to heat flow and offers better insulation.

2. Solar Heat Gain Coefficient (SHGC)

SHGC measures how well a window blocks heat caused by sunlight. The SHGC is the fraction of incident solar radiation admitted through a window, both directly transmitted and absorbed, and subsequently released inward. SHGC is expressed as a number between 0 and 1. The lower a window’s SHGC, the less solar heat it transmits.

3. Visible Transmittance (VT)

Visible Transmittance measures how much light comes through a window. It’s indicated by a number between 0 and 1. The higher the VT, the more light is transmitted.

4. Air Leakage (AL)

Air Leakage measures the rate at which air passes through the joints of a window. It’s measured in terms of cubic feet of air passing through one square foot of window area per minute. A lower AL means a tighter seal and fewer drafts.

5. Condensation Resistance

This measures how well a window resists the formation of condensation on its surface. Condensation resistance is scored between 0 and 100, with higher numbers indicating better resistance.

All these values are typically listed on a window’s NFRC (National Fenestration Rating Council) label, which provides a reliable way to determine a window product’s energy properties and to compare products. When choosing windows, consider each of these ratings in relation to your climate and your home’s orientation. For example, in a colder climate, you might want windows with a low U-factor for better insulative properties. Conversely, in a warmer climate, windows with a lower SHGC would be beneficial to reduce cooling needs.
