Four Seasons Hotel, USA /Global/References/Hotel/Four%20Seasons_Boston_BCB_176.jpg Stylish door hardware from ASSA ABLOY combined with VingCard electronic access control means guests at the Four Seasons Hotel in Boston enjoy easy and secure access to their rooms. CUSTOMER: The new Four Seasons Hotel and Private Residences, Boston, US, is a 61-story combined residential and guest facility, complete with 215 hotel rooms and 160 private residences. CHALLENGE: Project designers looked for door hardware to solve a couple of challenges: how to carry the triangular exterior design throughout interior spaces and, implement a state-of-the-art access control system. SOLUTION: Both of these objectives were solved with door hardware from ASSA ABLOY Group brands. Teams from ASSA ABLOY Opening Solutions Americas and ASSA ABLOY Global Solutions collaborated to address each project need. The Opening Solutions team worked with the building architects to create a custom lever to be used on all doorways. A specially designed triangular lever that matched the building’s exterior was completed under a program called SPAR (special application request). ASSA ABLOY design engineers worked with the architects to create an initial lever design that was rendered on a 3D printer, allowing for easy tweaks. This lever is installed on Yale hardware used on all secondary doorways and the VingCard locks found in all hotel room/residence entry doors. Electronic access control is provided by VingCard Essence locks that house all lock components, including the reader and mobile access board, inside the door, creating a minimalistic expression. The lock is mobile access ready and connects to an online system that communicates with guest room thermostats for energy management.
