US: Holcim Building Envelope supplied insulation and roofing systems, including its Elevate ISOGARD polyisocyanurate (PIR) insulation boards, to the 62-storey Winthrop Center tower block in Boston, Massachusetts. The Winthrop Center is the largest office building ever built on the Passive House positive energy efficiency model. Holcim Building Envelope says that its insulation and roofing systems deliver 40% better thermal performance than competing products, helping the block to achieve a 150% reduction in net energy use compared to an average Class A building in Boston.

Holcim Building Envelope commercial roofing systems & lining president Kristin Beck said "The Passive House certification of the Winthrop Center highlights the superior sustainable performance and quality of our Elevate products. This certification reinforces the effectiveness of Holcim's innovative building envelope solutions in significantly reducing energy consumption, and it also sets a standard for sustainable construction in cold climate regions."
