RENOVATE by Berkowitz

Window Retrofit System

A Lower Cost Alternative

Avoid complete window replacement.
Greater energy savings than window films.

Today, building owners, property managers, and the renovation consultants they work with are not only looking to improve the energy efficiency of aging buildings, but they also are trying to make them more competitive in a hyper-competitive commercial real-estate market.

While expansive windows and views are attractive selling points for any commercial building, older structures—between 30 to 60 years old—typically have single-pane windows. According to the Environmental Protection Agency, these inefficient windows place a heavy burden on HVAC systems, and account for as much as 25 percent of a typical building’s heating load in cold climates and 50 percent of the cooling load in warm climates.

It’s no surprise that a top priority for building owners is replacing old, drafty windows with newer, more energy-efficient glass. However, the cost of ripping out and replacing windows is often prohibitive and other measures, such as installing window film, are not an effective year-round solution.

To address this issue, the owners of J.E. Berkowitz (JEB) developed and Patented the Renovate by Berkowitz Window Retrofit System. Click here to learn more about the Renovate System.

    Preserve & Improve

    We believe that the greenest buildings are the ones that are already built. By retrofitting an existing building you can take that building and turn into the most efficient building it can be.

    Re-purposing an existing building makes sense not only in terms of dollars saved, but by the impact on the environment and available open space.

    There are many reasons to go green, but most come back to supply and demand. We have a limited amount of resources available and more and more people using them up. If we want our future generations to enjoy the same standard of living we have experienced we need to be proactive.
