To promote CO2 emission reductions in the industry that operates buildings, the benefits of single-pair Ethernet require specific efforts to digitize systems and implement automation.

Many countries and regions are currently working to achieve “net zero” greenhouse gas emissions in order to significantly reduce CO2 emissions.
However, the IEA (International Energy Agency) notes that “the industry involved in building operations is not making progress toward achieving its goal of zero global CO2 emissions by 2050.
It expresses concern that the net-zero goal will not be met unless the industry takes concrete action to digitize its systems and adopt automation.

There is one factor that further complicates this challenge. That is the need to be able to collect more real-time data in order to deploy effective automation.
Much of the current infrastructure is based on legacy communication technologies such as RS-485. In order to collect more real-time data, the throughput capacity and responsiveness of the infrastructure must be greatly improved compared to current levels.
In addition, connecting building-equipped equipment and systems to the network increases the risk of exposure to cyber-attacks.

The ever-growing cyber-attacks require advanced security features that far exceed the capabilities of older networks.
This paper describes how to digitize buildings by implementing single-pair Ethernet, exemplified by 10BASE-T1L.

Specifically, though, it is a way to upgrade buildings that are using older communication technologies such as RS-485 with single-pair Ethernet,
This will increase automation, improve security levels, reduce energy consumption, and increase sustainability.
