In this week’s post, a look back on the keynote presentation given by Farukh Aslam and Luis Suau to the CABA Intelligent Buildings Council (IBC) at its November 2020 meeting, on the technology powering and enabling building automation in the famed Marriott Sinclair Hotel. The Marriott Sinclair Hotel, which opened in January of 2020, has been dubbed the pinnacle of digital buildings—a 16 story, 1929 era historical building whose use changed from an office building and was transformed into a Marriott Autograph collection boutique luxury hotel.
Pivotal to that transformation was the extensive use of Power-Over-Ethernet; the project also included the use of the first LG Li-Ion Energy Storage System in the U.S. and use of VoltServer’s Digital Electricity to power the distributed network—the closest deployment to a DC Building microgrid.
What drove the use of PoE and digital electricity in this unique project? Farukh Aslam, CEO and President, Sinclair Holdings, LLC and Luis Suau, VP/CTO, Sinclair Digital LLC discussed their implementation journey. With PoE, they explained, by removing the driver from the light multiple lights could be powered with a single driver. This made it possible to communicate with each of those lights on a network, getting notification when maintenance is required. Moreover, powering of all the lights in a room, and similar powering of other low-voltage devices, was achieved through the Cisco Digital Building Switch.
The presenters also recounted their path to digital electricity and described the key outcomes. With digital electricity, the new system could send large amounts of electricity over 18/2 cables in packets. It provided Class 2 power that is safe to handle, eliminating the need for complicated installation. This deployment also opened the door to intelligent load shedding capabilities to distribute power based on priority in the event of a power outage, and finally, the opportunity to remove traditional A/C power.
