Building Envelope Consultant
Completed in 2012, Eaton Corporation’s new headquarters brings 700 employees scattered across offices and complexes located in and around the Greater Cleveland Area together in one building. The new headquarters consists of a central ten-storey tower flanked by two five-storey wings. Employees of this Fortune 500 company avail themselves of modern office space, conference rooms, an auditorium, a five-storey atrium with a conservatory dining area, a three-storey wellness centre, an outdoor terrace and enclosed parking.
A sloping point-supported structural glass wall forms the entrance atrium, while structural glass fin walls accent the exterior of the conservatory. Our design ensured thermal and air infiltration continuity across a number of expansion joints throughout the development.
Challenge: The building’s exterior features sunshades that introduce thermal bridges to the building envelope. Supports for these sunshades allow snow, ice and freezing rain to accumulate in winter.
Solution: We designed the envelope to deal with potential thermal breaks. We also took a variety of measures to ensure that potential accumulations of snow and ice on the sunshade supports do not create hazards to pedestrians below. We also used back pans, a common feature on Canadian curtain wall systems that are still rare in the United States.
