Energy-efficient window solutions

Windows are often a leading culprit in energy waste and tenant discomfort. In fact, as much as 35% of building energy waste is due to inefficient windows. Fortunately, there are a variety of technological and energy-efficient solutions that can help you stop wasting energy, while increasing tenant comfort, reducing noise, and lowering operating costs. Get to know your most cost-effective, energy-saving options below.  

Secondary Glazing Systems

Ideal for medium- to larger-sized buildings (20,000 sq. ft. or more), secondary glazing systems attach to the interior of an existing window to create an insulating barrier. For half the cost, you’ll get the same amount of energy savings as you would by replacing your windows with energy-efficient models.

Low-E Storm Window Attachments

Low-emissivity (low-e) storm windows attach to an existing window’s interior or exterior to create an insulating pocket of air between the windows. Ideal for small- to medium-sized buildings (20,000 sq. ft. or less), the low-e coating helps regulate interior temperatures by limiting unwanted heat transfer.

Window Replacement

A smart option for any building size or type, replacing inefficient windows with high-efficiency windows can be a standalone measure or part of a deeper retrofit. This approach requires higher upfront cost but can increase property value and reduce operating costs.
