Building Automation System

Building automation systems are used to meet the increasing requirements for energy efficiency and sustainability of buildings. In such systems, BACnet has established itself as the standard communication protocol for communication between devices from different manufacturers. In order to ensure conformity with the BACnet standard, the devices are certified for conformity. In practice, however, the implementation depth described in the standard profiles is not sufficient for operating a system. As a result, many users demand an extended implementation depth of the BACnet protocol. In most cases, an AMEV certificate is sought, which extends the BACnet objects and their properties in comparison to the standard certification. Despite the BACnet standard certification and the fulfilment of the AMEV test certificate, problems often occur during the operation of building automation systems. These problems can be attributed to the fact that neither the functionality nor the performance of automation stations are determined. In addition, special user requirements are not checked before commissioning a building automation system. For this reason, a model was developed with the help of which a pre-commissioning of the automation station is possible in order to automatically check it for errors and special user requirements before commissioning. Initial tests of automation stations revealed that some user requirements were not met.

Staff Intervention

A fault detection and diagnostics (FDD) tool is a type of energy management and information system that continuously identifies the presence of faults and efficiency improvement opportunities through a one-way interface to the building automation system and the application of automated analytics. Building operators on the leading edge of technology adoption use FDD tools to enable median whole-building portfolio savings of 8%. Although FDD tools can inform operators of operational faults, currently an action is always required to correct the faults to generate energy savings. A subset of faults, however, such as biased sensors, can be addressed automatically, eliminating the need for staff intervention. Automating this fault “correction” can significantly increase the savings generated by FDD tools and reduce the reliance on human intervention. Doing so is expected to advance the usability and technical and economic performance of FDD technologies. This paper presents the development of nine innovative fault auto-correction algorithms for Heating, Ventilation, and Air Conditioning pi(HVAC) systems. When the auto-correction routine is triggered, it overwrites control setpoints or other variables to implement the intended changes. It also discusses the implementation of the auto-correction algorithms in commercial FDD software products, the integration of these strategies with building automation systems and their preliminary testing.

Architecture Component

This article presents the information on control system of smart building, which is considered as a set of subsystems including a building automation system. The paper considers the three-level architecture of the building automation system components, including FPGA, communication and management levels. It is determined that the causes of failures and inaccessibility of the BAS architecture component can be both internal system and external factors, among which software defects and vulnerabilities are identified. BAS security and availability during its life cycle are assessed using the Fault-, Attack- and Availability-Tree and Markov models. Markov model is used to develop a number of strategies which help to recover system and to eliminate all the possible threats during systems life time. The models of BAS architecture with software defects and attacked vulnerabilities with general reliability (defect) and security (vulnerability) maintenance are analyzed in detail. The recommendations on the choice of strategies and service parameters are given.

AbstractEver growing building energy consumption requires advanced automation and monitoring solutions in order to improve building energy efficiency. Furthermore, aggregation of building automation data, similarly to industrial scenarios allows for condition monitoring and fault diagnostics of the Heating, Ventilations and Air Conditioning (HVAC) system. For existing buildings, the commissioned SCADA solutions provide historical trends, alarms management and setpoint curve adjustments, which are essential features for facility management personnel. The development in Internet of Things (IoT) and Industry 4.0, as well as software microservices enables higher system integration, data analytics and rich visualization to be integrated into the existing infrastructure. This paper presents the implementation of a technology stack, which can be used as a framework for improving existing and new building automation systems by increasing interconnection and integrating data analytics solutions. The implementation solution is realized and evaluated for a nearly zero energy building, as a case study.
