Building Automation in the Modern Era: The Role of BACnet, Model-Based Cloud Analytics, and Service Transparency
Paving the Way for a Fresh Economic Agenda
In the realm of modern building automation, three key concepts have emerged as indispensable: BACnet, model-based cloud analytics, and service transparency. While these concepts did not directly originate during the New Deal era, they have grown to become the backbone of efficient and effective building management.
BACnet: A Universal Language for Building Systems
First and foremost, BACnet is a network protocol that enables various building systems to communicate and operate together seamlessly. Initially developed for use in serial communication networks, BACnet has since evolved to adopt TCP/IP and is now moving towards Web Services. This open standard is the foundation of the Industrial Internet of Things (IIoT) for buildings, making it the best way to instrument the complex engineered building system.
BACnet encapsulates metadata about the devices on the network, which helps reduce the complexity of the building control system. It also allows vendors of specialized products to create non-standard information profiles that allow their devices to be a responsible citizen of the BACnet network.
Model-Based Cloud Analytics: Optimizing Building Performance
Model-based cloud analytics is another crucial component of modern building automation. This technology creates a cloud-based digital twin of the building, replicating the structure of the system and allowing continuous modeling of the building in the cloud. This digital twin can identify issues where the physical system is not operating correctly and can often determine the cost of problems. It can also rewind the system to analyze the building as it was operating at some past date, useful as a forensic tool for investigating unusual energy costs or complex systemic issues.
Service Transparency: Bridging the Gap Between Vendors and Owners
Service transparency is the third pillar of modern building automation. This concept ensures that building owners and operators have access to detailed information about their facilities' operations, aiding in maintenance and efficiency improvements. Service transparency serves to improve the relationship between vendors and owners, as well as contributing to improving their respective businesses. It enables them to analyze problems, propose solutions, and review decisions openly, without finger-pointing.
In essence, the New Deal attributes of accountability and transparency have found a modern expression in the form of BACnet, model-based cloud analytics, and service transparency. These concepts, while not directly influenced by the New Deal, have helped to create a more efficient, transparent, and accountable building automation landscape. Just as the New Deal laid the groundwork for infrastructure development, these modern attributes have laid the groundwork for the future of building management.
