2022 saw noteworthy milestones in the development of cabling infrastructure standards for smart buildings. In March, TIA released the ANSI/TIA-568.5 Single Pair Ethernet (SPE) cabling standard. Four months later, TIA released the ANSI/TIA-862-C Intelligent Building standard with technical updates and topologies that facilitate connecting and powering IoT devices, including the addition of SPE standards (in alignment with 568.5). Recently, the National Fire Protection Association Standards Council voted to issue the 2023 National Electrical Code (NEC) with Class 4 fault-managed power that will expand the use of energy-saving direct current (DC) power over low-voltage cabling, which is incentivized by the U.S. Green Building Council’s LEED version 4 pilot credit Direct Current Power Systems.
These milestones encourage cabling infrastructure design and implementation practices that improve connectivity and sustainability in smart buildings—but the market remains in its infancy. The lack of actual products available on the commercial market complicates new-project design. But technology providers can adopt strategies today to help future-proof infrastructure for tomorrow.
