Energy-efficient replacement windows with the ENERGY STAR® label have made a huge impact on every U.S. household. They not only help reduce the impact of greenhouse gases and other pollutants produced by inefficient products but also help customers to pick high-performance products that will help them save on energy costs. However, how do they determine whether one product earns the government-backed symbol? In this post, we’ll discuss it in more detail.

Basic Requirements
According to the Environmental Protection Agency (EPA), there are specific energy efficiency requirements that products have to meet to become ENERGY STAR-certified. As expected, these items should be able to contribute to nationwide energy savings whilst meeting the features and performance requirements demanded by the customers.
Moreover, the customers should be able to get a return on their investment through their monthly utility costs compared to their less-efficient counterparts. In this case, if you purchase an ENERGY STAR-certified window replacement, it should be able to significantly reduce a homeowner’s energy costs within a reasonable amount of time.
Deciding When to Revise The Specifications
It is important to note that a market share of ENERGY STAR-certified products in a particular category of 50% or higher will prompt consideration for a specification revision. But there are other factors that weigh into the decision and these are:
- A change in the Federal minimum efficiency standards
- Issues with test procedures and energy savings
- Performance or quality concerns
- Product availability
- Technological changes with advances in energy efficiency prompting a revised ENERGY STAR specification to capture additional savings.
