In many cases, an owner or building manager needs to improve window function and performance in order to satisfy tenant or occupant requirements, or as part of a property upgrade.

Zion Garden Apartments (Philadelphia, PA) this multifamily, 101 unit garden apartment installed the QUANTAPANEL 504-DH IGS (exterior, operable) to replace existing exterior storm windows as an energy improvement investment.  The building realized a 20% reduction in annual heating cost a 9% – 15% reduction in cooling cost and a 10% reduction in air infiltration.

 

2601 Parkway Condominium (Philadelphia, PA) this 500 unit condominium was built in 1940 and is located near the Philadelphia Museum of Art.  The existing metal-frame are a source of high energy bills and occupant discomfort.  Under a program implemented by the building management, residents have opted for installation of the QUANTAPANEL 605-DH IGS (interior, operable).  Individual condo owners have implemented the improvement at a fraction of the expense of window replacement for the entire building, have reported exceptional improvement in energy, comfort and air infiltration with no visible change to the exterior façade of the building.

 

Waldorf School (Pittsburgh, PA) this private school is located in a 1867 Victorian-era mansion in the historic Bloomfield area of Pittsburgh.  In order to improve comfort and reduce energy cost, the school selected the QUANTAPANEL 605-DH IGS (interior, operable) for installation in select classrooms in the school.  The administration reported a noticeable difference in classroom comfort.  As the building is a designated historic landmark, the improvement needed to be completed without any change to the exterior of the structure.

 

French Apartments (New York City, NY) this multifamily property undertook a major energy improvement project in 2013 which included the installation of the QUANTAPANEL® 605-DH IGS (operable, double hung, interior installation). The project objective was to achieve a 38% energy reduction, a major portion of that improvement being realized by reduced air infiltration and enhanced thermal properties in the existing windows.

 

777 Main Street (Hartford, CT) this 26 story tower, built in 1969, was the former world headquarters for the Hartford National Bank.  It has been repurposed into a 295,000 SF residential building with 285 units.  The existing windows are large monolithic glass retained within the exposed aggregate structure of the exterior façade. The building owner targeted LEED Platinum certification with a goal of achieving 45% higher energy efficiency than code requirements. The interior low-e glass system developed for this property is a key contributor to the energy performance improvement.
