For Designers

Why should a designer choose energy-efficient windows?

Improve performance for clients

Energy-efficient windows can save clients money on utility bills. Energy-efficient windows also provide increased comfort, reduced condensation, and can improve durability.

More Stringent Code Requirements »

Building energy codes are continually being revised to require greater energy efficiency in buildings and windows in particular. Many codes refer to the NFRC label as the means of certifying window energy performance. Designers must meet these requirements to compete in each state.

Meet Green Building Program Criteria »

An increasingly important trend in the building industry is the emergence of the sustainable or green building movement. Awareness of global warming and climate change has become a particularly strong driving force in this movement. In the residential sector, there are many green building guidelines, rating systems and standards. High performance windows will be necessary to meet the requirements of these programs.

Take Advantage of Utility Program and Tax Incentives »

Utility-sponsored programs stimulate the adoption of energy-efficient technologies in a variety of ways including providing customers or builders with information, technical assistance, and direct (e.g., cash rebates and discounted rates) and indirect (e.g., lower cost financing) financial incentives. In addition, federal and state governments may offer tax credits to encourage efficient technologies.
