Boston, Massachusetts, U.S.A.

Winthrop Center in Boston stands as the world's largest Passive House-certified office building, a groundbreaking achievement in energy-efficient design. With the guidance of leading architects and experts, Millennium Partners conceptualized the building to reduce operational emissions by incorporating innovative energy-saving solutions. Holcim contributed to this project with its high-performance Elevate™ ISOGARD™ polyiso insulation and UltraPly™ TPO SA membrane, ensuring superior thermal efficiency and protection from harsh weather conditions.

By applying Passive House principles across its design, Winthrop Center achieved 65% less energy use than a typical office building in Boston. Holcim’s insulation technology provides up to 40% better thermal performance, even in cold weather, contributing to the building’s air-tight exterior and low-carbon status. The result is an energy-efficient, healthy, and comfortable environment for its occupants, setting a new benchmark for sustainable buildings in cold climates.

Colorado Springs, Colorado, U.S.A.

Set against the stunning backdrop of the Colorado Rockies, the new Air Force Visitor Center embodies innovation and bold design. Inspired by the sleek form of a B-2 bomber, the center is more than an architectural marvel; it is a testament to sustainable and functional roofing solutions. To meet the demands of this ambitious project, Douglass Colony Group installed an Elevate UltraPly™ TPO system, chosen for its exceptional durability and performance in Colorado’s harsh winter climate.

The roof’s complex design required precision to ensure proper drainage and watertight installation while meeting the building’s aesthetic goals. Innovative techniques, like using hotboxes to maintain optimal material temperatures during winter construction, enabled the team to overcome freezing conditions. This project showcases the power of resilient, energy-efficient materials and the commitment of the Douglass Colony Group to excellence in roofing design.

Athens, Ohio, U.S.A.

The Athens Community Center is a vital hub for the city, hosting fitness classes, child care programs, private events, and an art gallery that enriches lives across generations. Faced with leaks in its aging roofing system, the city prioritized sustainability in its renovation plan, integrating innovative solutions that align with its mission to cut carbon emissions by 50% within the next decade.

Damschroder Roofing utilized Duro-Last’s Recycle Your Roof program to replace 47,000 square feet of old membrane with energy-efficient Duro-Tuff® materials, recycling the old roof into functional products. The project also included the installation of over 1,800 square feet of solar panels, offsetting 80% of the facility’s electricity needs, and 12 new tie-off points to enhance safety. This renovation demonstrates how community spaces can seamlessly integrate sustainability and functionality, benefiting both residents and the environment.

Washington, D.C., U.S.A.

Home to over 6,000 works of art spanning centuries, the National Museum of Women in the Arts is a cultural treasure in Washington, D.C. Originally constructed in 1907, the historic terracotta brick and steel building lacked modern insulation, making it challenging to maintain consistent temperature and humidity levels critical for preserving priceless artwork.

To address these challenges, the museum retrofitted its walls and roof deck with Enverge® NexSeal 2.0 Closed Cell Spray Foam. This solution provided superior air sealing, moisture resistance, and thermal performance, reducing energy loss through the building envelope by over 50%. By creating an optimal environment for both artwork and visitors, Enverge NexSeal has ensured that this iconic space remains energy-efficient and well-preserved for generations to come.

Bozeman, Montana, U.S.A.

In the mountains outside of Bozeman, Montana, roofing contractor Forest Dennis and his team installed 110 squares of Malarkey’s Legacy® shingles to earn the top honor in the 2024 Excellence in Asphalt Roofing Awards. This award, presented by the Asphalt Roofing Manufacturers Association (ARMA), recognizes outstanding performance, beauty, and innovation in asphalt roofing.

The Legacy® shingles, with a Class 4 impact rating and 130 mph wind warranty, provided the durability and eco-friendly materials necessary for this project. Nestled in a picturesque valley near Yellowstone National Park, the home’s new roof blends seamlessly with its natural wood and stone exterior, ensuring both aesthetic appeal and long-term resilience against Montana’s harsh climate.
