Building Automation

The advancement in automation platforms has been driven largely by the development and adoption of BACnet. BACnet stands for Building Automation Control Network which is a communications protocol for building automation and control networks.

BACnet was designed to allow open communication within building automation and control systems for applications such as heating, ventilating, and air-conditioning control, lighting control, access control, and fire detection systems and their associated equipment.

BACnet (open-protocol) automation for buildings has given owners the ability to install and own effective tools for managing energy and operating costs.The installation costs associated with digital direct control (DDC) systems including graphics and internet connectivity have decreased markedly in the past 10 years. Open protocol systems are good solutions for aging pneumatic (air) control systems.

However, there is a caveat. The industry standard ‘upgrade’ doesn’t address the existing deficiencies in HVAC systems. The savings available from any investment assumes all of the controlled equipment and systems are fully operational and maintained.

Investment-driven projects are based on an expected ROI. The energy and maintenance savings that DDC systems are calculated to deliver are ‘stipulated’. That’s an industry term for assumed; meaning they are going to have numerous exclusions for existing conditions and for changes in the operating assumptions used when the payback was calculated.

Without understanding the cost of the repairs or changes needed to existing systems in advance and including those costs in the investment calculations, these projects seldom perform as intended.
