This case study explores the unique solutions employed for a unitized curtain wall facade at the Raffles Boston Back Bay Hotel & Residences, a new 35-story tower nearing completion in Boston’s urban core., and located on a prominent corner site with a complex set of environmental and contextual conditions.
While no building product component or system is truly “bulletproof,” industry resources are evolving to evaluate, select, and specify high-performance, aluminum-framed curtain wall, storefront, entrance, and window systems which can help protect against active shooter attacks in schools, universities, and other facilities.
Laboratory testing is the typical way to verify that fenestration products meet specified structural design pressure (DP) criteria. However, engineering analysis can be a viable alternative when standard lab testing will not be sufficient. This article dives deeper into the Fenestration and Glazing Industry Alliance (FGIA)’s consensus-based process for engineering evaluation of structural integrity: AAMA 2502, Comparative Analysis Procedure for Window and Door Products—which is now approved as a reference standard in the International Building Code (IBC).
