The Kendeda Building for Innovative Sustainable Design at Georgia Tech Includes Polyiso

The Kendeda Building for Innovative Sustainable Design (Kendeda Building) at the Georgia Institute of Technology (Georgia Tech) was dedicated on October 24, 2019. Built in partnership with the Kendeda Fund, the 46,800-square-foot building is the first academic and research building in the Southeast to pursue the Living Building Challenge – the world’s most ambitious green building program.

The Kendeda Building will need to meet 20 “Imperatives” – which are specific performance requirements – after 12 consecutive months of operation. Certification is anticipated in 2021, and the project is also pursuing the U.S. Green Building Council’s LEED certification at the Platinum level.

The project team used a three-inch base layer of non-halogenated GAF Polyiso roof insulation to cover nearly the entire roof and approximately 130 squares of material GAF TPO. This GAF polyiso insulation does not contain halogenated flame-retardant chemicals and offers:

  • A higher R-value per inch compared to non-polyiso types of insulation of equivalent thickness;
  • High moisture resistance;
  • Improved fire resistance;
  • Are lightweight for easy handling and installation;
  • Have zero ozone depletion potential and negligible global warming potential, and;
  • Manufactured with EPA-compliant blowing agents containing no CFCs or HCFs. 

The Kendeda Building will use just one-third the energy of a comparable building, will generate more energy than it uses from solar panels on its roof and will capture and treat rainwater for all purposes, including drinking. This is one of the reasons the project team chose to integrate tapered Polyiso roof insulation in addition to the flat material to help direct water into the capture systems.

The building includes classrooms, laboratories, offices, an auditorium, a student commons, and a roof garden with an apiary. The project offers unique learning opportunities for designers, builders, and building operators, such as how to tackle the region’s humidity and potential droughts.

The Living Building was funded through a $30 million grant from The Kendeda Fund, one of the leading philanthropic investors in civic and environmental programs in the Atlanta area with a commitment to ecological and social causes.

Agropur Dairy Cooperative

In 2016, the dairy cooperative Agropur opened a new, two-story office building in Longueuil, Québec that went on to earn a Leadership in Energy and Environmental Design (LEED) certification from the Canada Green Building Council in 2017. The ambitious project allowed Agropur to consolidate four existing offices into a single, unified 23,226-m2 (250,000 square foot) campus in a tranquil wooded environment adjacent to its existing distribution center and quality assurance labs.

The new campus offers a state-of-the-art office environment, underground parking for 700 cars, with carefully designed amenity areas, including a cafeteria, gymnasiums, and relaxation and conference rooms. Conceived as a series of narrow wings, the building layout takes advantage of plentiful windows to bring in natural light and continuous views of the surrounding forest.

The building was designed by Le Groupe Architex and the roof was installed by Truchon Roofing. Since the exterior of Agropur’s building is glass, care was taken in the plans to facilitate efficient regular window washing. The roof needed solid bases to protect it from the heavy equipment and accompanying workers who would launch from the roof.

The architect chose SOPREMA high-density polyiso cover boards to ensure that roof materials installed below the cover board would not be damaged by the additional loads and traffic. Unlike other types of cover board, the high-density polyiso cover boards also added thermal resistance, contributing to improved energy efficiency.

“The architect was looking for something solid and durable under the SBS-modified bitumen that would keep the lower roof materials from being damaged by the extra loads.” said Sylvain Dion, Architectural Sales representative at SOPREMA. “They had been considering the cement board, but when they learned more about the durability and added thermal value of the high-density polyiso cover board, they selected it for the roof.”

Commercial low-slope roof systems are expected to perform throughout the entire service life of a building, so understanding and utilizing products to help enhance the roof’s performance and longevity is essential for good roof design. With proper installation, HD polyiso cover boards are versatile and resilient low-slope roof system solutions. Whether it is exposed to severe weather or maintenance personnel servicing rooftop equipment or window washing, choosing a long-lasting roof system means satisfied building owners.
