How is energy-efficient glazing recommended for residential structures?

• A. Through the use of single-pane glass
• B. By installing efficient double-glazed units and low-E coatings
• C. By using standard clear glass
• D. Through the application of tinted films only

Answer: (B)

Energy-efficient glazing is recommended for residential structures primarily through the installation of efficient double-glazed units along with low-emissivity (low-E) coatings. This approach significantly enhances the thermal performance of windows. Double-glazed units consist of two panes of glass with a space in between, which acts as an insulating barrier. This design helps to reduce heat transfer, keeping homes warmer in the winter and cooler in the summer. Low-E coatings on the glass further improve energy efficiency by reflecting infrared energy while allowing visible light to pass through. This keeps the interior comfortable while minimizing energy loss, ultimately leading to reduced heating and cooling costs. In contrast, using single-pane glass and standard clear glass provides minimal insulation, leading to higher energy consumption. In addition, relying solely on tinted films may not adequately address thermal performance, as they primarily focus on reducing glare and solar heat gain without improving insulation significantly. Therefore, the combination of double glazing and low-E coatings represents the best energy-efficient solution for residential glazing.
