Window Replacement: Unrealized Benefits

Most U.S. buildings currently in use will continue to be until 2050 and, eventually, will require renovation. Helping building and property managers evaluate and maximize the benefits of window system renovation and upgrades, Apogee Enterprises, Inc.’s Building Retrofit Strategy Team offers a new 28-page publication. “Window replacement: Unrealized benefits to building owners” is available free for download at

“Replacing aging windows with new, high-performance systems provide a better environment for the building’s occupants and greater value for the building owner,” says John Bendt, vice president of Apogee’s Building Retrofit Strategy Team.

“Window systems and components have evolved significantly since the 1980s,” explains Kevin Robbins, Apogee’s Building Retrofit Strategy Team account manager. “About half of all U.S. commercial and institutional buildings were constructed prior to this period, which presents a significant opportunity for owners and occupants to benefit from façade improvements and window replacement.”

Bendt continues, “Among the many benefits, modern window systems improve the appearance and performance of aging buildings. New, high-performance glass and aluminum frames with thermal barriers help save energy, reduce maintenance, lower vacancy rates, increase rental rates, provide a better environment for the building’s occupants and creates greater value for the building owner and enhance occupants’ satisfaction and comfort.”

Describing these benefits and best practices in achieving them, the paper shares nine case studies along with detailed considerations regarding energy payback, fossil fuel savings equivalents, code compliance and green standards, environmental stewardship, tax credits, product selection and renovation specification tips, plus a glossary of industry terms and acronyms.

The paper’s projects range from the 1800s to the 1970s with geographies from Boston to Portland, Oregon, and include the State University of New York (SUNY) Fredonia Campus’ Andews Complex featuring Tubelite‘s storefront and entrance systems. As many of the project examples demonstrate, re-cladding and renovating building exteriors with high-performance window systems can have a significant affect on the building’s energy efficiency. To compare performance data between a building’s existing windows and proposed, new, high-performance, replacements units, Apogee’s Retrofit Strategy Team offers free energy modeling that provides building performance information on annual energy, peak demand, carbon emissions, daylight, glare, and condensation.

“Looking beyond simple energy payback, today’s owners and facility managers consider all the factors involved, including carbon footprint reduction, maintenance savings, and safety and occupant productivity,” adds Robbins. When window replacement is timed in conjunction with an HVAC system upgrade, significant reductions in peak load can yield further savings in equipment costs. For building owners seeking enhancements in security, design criteria for façade renovation also can include blast hazard mitigation, hurricane impact resistance, electronic eavesdropping protection and forced entry deterrence.

“Establishing clear goals, priorities and expectations for building envelope maintenance and renovation will significantly contribute to future success. Working with an experienced building envelope retrofit team that includes the installer and manufacturers, building owners and facility managers will optimize the intended benefits and return on investment,” concludes Bendt.

Tubelite shares expertise on thermal barriers

Sharing his knowledge with the industry, Tubelite’s Doug Dietrich recently authored a Know Your Products column on “Fenestration’s Thermal Barriers” for Metal Construction News.

He explains that when aluminum extrusions are shaped into framing for window, entrance, storefront and curtainwall systems, a break in the thermal path is necessary between the interior and exterior surfaces. This thermal barrier reduces the transfer of heat through the aluminum, keeping occupants at their desired, comfortable, indoor temperature and maintaining the structural integrity of the aluminum profiles.

The column continues with a description of thermal barrier types and U-factors. He also reminds readers to check that Division 8 aluminum framing and glazing specifications for U-factor align to meet the specified project requirements as determined by local codes.

Tubelite achieves NFRC ACE certification

Tubelite Inc. has been approved by the National Fenestration Ratings Council (NFRC) as a Manufacturer Approved Calculation Entity (ACE) Organization. NFRC is the global leader in delivering energy and related performance ratings and certification for fenestration products and systems.

In addition to the company’s ACE certified individuals in both the engineering and marketing departments, three Tubelite representatives have earned a Certificate of Approval for successfully completing the ACE Training Workshop: client development manager Dan Goodman, and representatives Rick Hillesheim and Matt Tschida of Hillesheim Architectural Products, Inc.

As an NFRC ACE, each is qualified to carry out performance calculations of fenestration products for design support and final certification using the NFRC Component Modeling Approach (CMA) and software tool (CMAST). Through NFRC’s CMAST libraries of approved frames, glass and spacer components, users can configure fenestration products for a project, and can obtain a U-factor, solar heat gain coefficient and visible transmittance rating for those products. Performance values are then compared to the energy requirements of local energy codes to determine compliance.

Performance of specific Tubelite frame-glass combinations can be obtained from the NFRC Certified Products Directory or the CMA process. In addition to active product listings in the NFRC Certified Products Directory for factory-glazed fenestration, Tubelite has several approved curtainwall, storefront and entrance system products in the CMAST library, and new product variations frequently are added.
