Society is going through an energy transition, but part of that is also a conceptual transition: we diagnose people, but buildings are static – they just sit there and serve whatever purpose they were built for, such as residential or office use.
With IoT and Smart Buildings as part of the transition, that is shifting. Buildings now can generate, as well as consume power. Lighting can change due to users' needs. Natural air-flows are better for people than air-conditioning. You can route excess heat from your computer servers to grow plants in greenhouses...so building systems need to develop to be active, not passive.
The need to optimize energy consumption while reduce costs and ensuring the comfort of the building's users is speeding up the development and deployment of advanced technologies of various kinds to create “Smart Buildings”.
Automated Demand Management (ADM) Promotes Energy Efficiency
Automated Demand Management (ADM) can be a major component of energy efficiency in buildings. ADM systems monitor and control the energy consumption of modern building systems based on occupancy, weather conditions, lighting needs and other factors. ADM ensures that resources are allocated efficiently by automatically adjusting energy usage, and that energy is not wasted. This proactive method of energy management significantly contributes to overall energy efficiency, allowing building operators to optimize energy consumption and reduce costs. Now factor in a microgrid and a local energy market, so several buildings can share energy and reduce their costs; the building's systems will need to interface with that.
Then there are the normal issues of operating a complex system: faults, breakdowns and the need to replace worn components without causing unnecessary disruption. Fault Detection and Diagnostics (FDD) tools are needed here. FDD software and hardware allows building operators to identify and rectify issues in real-time, ensuring optimal performance and improved energy efficiency.
When ADM programs integrate with FDD, they become more powerful because they are able to take into account the actual operation of the equipment before integrating them into demand management programs. This gives O&M teams new incentives to fix problems, and allows automation strategies the best possible chance at success with the least amount of associated risk.
Best Practices for Fault Detection and Diagnostics in Smart Buildings
To ensure the effectiveness of a Fault Detection and Diagnostics system, best practices would include these major components:
-
Robust data acquisition and monitoring capabilities are essential for collecting accurate and reliable information in real time.
-
Advanced analytics tools are required to analyze the data and detect anomalies and faults accurately.
-
A user-friendly interface is critical to enable building operators to interpret the data and take appropriate actions.
-
Seamless integration with existing energy management systems allows for a seamless approach to energy management and optimization.
The integration of ADM and FDD systems with smart grid technologies will further optimize energy management and enable buildings to participate in demand response programs. As FDD systems become more sophisticated and accessible, they will undoubtedly become an integral part of energy-efficient buildings.
The implementation of these systems, particularly in new-builds, as they can be designed-in rather than be costly retrofits, will be part of the progression to Smart Cities, where utilities can monitor energy production and demand in real time and not only utilize their resources most effectively, but also by using market-making methods, such as letting smart appliances, for example a washing machine, use low-price energy in the middle of the night to ensure the system is working at its maximum efficiency which enables lower production and reduced emissions while still keeping sufficient power supplied to the users.
