The energy efficient windows work using multiple layers of glass instead of just one, which was common for the beginning of the 1980s. Since conduction is one of the main reasons for heat loss, with multiple glass layers, this effect is reduced to the minimum.

Energy efficient windows work by reducing heat loss and heat gain through the glass. They typically have multiple panes, Low-E coatings, and insulating gas between the panes to improve insulation properties. This helps maintain a consistent indoor temperature, leading to lower energy bills and increased comfort.
No, it is not energy efficient to run the air conditioner with windows open. This practice can lead to wasted energy as the cool air from the air conditioner escapes through the open windows, causing the unit to work harder to maintain the desired temperature.
There are several types of energy-efficient windows, including double-pane, triple-pane, low-emissivity (low-e) coating, gas-filled, and insulated frames. Each type has specific features to reduce heat loss and boost energy efficiency in homes or buildings.
Double-paned windows are more energy-efficient than single-paned windows because they provide better insulation. However, triple-paned windows are even more energy-efficient as they have an extra layer of glass and airspace, further reducing heat loss. Selecting the most energy-efficient windows depends on factors such as climate, orientation, and budget.
Some of the best energy-efficient windows brands include Andersen, Pella, and Marvin. These companies offer various features like low-E coatings, gas fills, and multiple panes to improve energy efficiency and reduce heat loss. Be sure to look for windows with a high energy star rating for optimal performance.
Leaving the window open while the AC is on is not energy efficient because it allows cool air from the AC to escape outside, making the AC work harder to maintain the desired temperature. This can lead to higher energy consumption and increased costs. It is recommended to keep windows closed when using the AC to maximize energy efficiency.
