During a major renovation, the Beinecke Rare Book & Manuscript Library at Yale University was left without its permanent HVAC system, putting one of the world’s most significant collections of rare books and manuscripts at risk. The library houses priceless materials, including Gutenberg Bibles, early maps, and centuries old texts stored in a central glass tower and extensive underground stacks.
A large paper manufacturing facility in Quebec has been dedicated to producing high-quality paper rolls used across the region. The cardboard cores used for winding these rolls must remain dimensionally stable to support reliable production and consistent product performance.
As part of an extensive modernization and technical upgrade of patient wards at the largest hospital in Stockholm, Polygon has been entrusted with ensuring a controlled and moisture-safe environment throughout the construction process.
The University of the Fraser Valley (UFV) in British Columbia is expanding its Abbotsford Campus with several buildings including student housing. Clark Builders, a division of Turner Construction, is leading the construction of the 400-bed six-story residence set to open in 2025. The 149,400-square-foot hybrid structure is comprised of reinforced concrete, mass timber, and light wood framing. The UFV Integrated Project Delivery (IPD) team was keen to incorporate a multi-faceted humidity control system into the temporary heating plan to ensure optimal conditions were maintained for the light wood framing and cross-laminated timber (CLT) floor system throughout the winter months.
For years, the importance of good Indoor Air Quality (IAQ) on our health and productivity has been the focus of experts and regulating bodies. In the last decade, organizations like ASHRAE and the U.S. Green Building Council have recommended that buildings upgrade MERV 8 filters. In fact in 2019, the California Building Code declared MERV 13 filters as a mandatory requirement for some building types. Then the COVID pandemic amplified the conversation about the benefits - and the costs - of the private and public sector swapping at scale.
