A building management system (BMS), also known as a building automation system (BAS) or a building energy management system (BEMS), is a computer-based control system installed in buildings that controls and monitors the building’s mechanical and electrical equipment. It includes such things as: ventilation, lighting, electrical systems, fire extinguishing systems and BMS security systems (software and hardware). The software application, which is usually configured hierarchically, can be proprietary and use protocols such as: C-Bus, Profibus, etc. Vendors also produce a BMS that integrates the use of Internet protocols and open standards such as: DeviceNet, SOAP, XML, BACnet, LonWorks, Modbus or KNX. A BEMS may focus on the energy consumption and performance of a building rather than a broader range of building functions.
Building management systems are typically implemented in large projects with extensive mechanical, HVAC, and electrical systems. Systems connected to BMS usually represent 40% of the building’s energy consumption. If brightness is taken into account, this number approaches 70%. BMS systems are a critical part of energy demand management. Improperly configured BMS systems are believed to account for 20 percent of building energy use, or approximately 8 percent of total energy use in the United States.
In addition to controlling the building’s interior environment, BMS systems are sometimes linked to access control (turnstiles and access doors control who is allowed to enter and exit the building) or other security systems such as closed-circuit television (CCTV) and motion detectors. Sometimes fire alarm systems and elevators are connected to BMS for monitoring. If a fire is detected, only the fire alarm panel can close the dampers of the ventilation system to prevent the release of smoke, close the vents, turn on the smoke exhaust fans, and send all elevators to the ground floor and park them to prevent people from entering. to be Building management systems also incorporate disaster response mechanisms (such as foundation isolation) to save structures from earthquakes. In recent times, companies and governments have been working to find similar solutions for flooded areas and coastal areas at risk of sea level rise. One such example is the SAFE Building System by Arx Pax Labs, Inc., which is designed to float buildings, roads, and facilities in several feet of water. The self-regulating floating environment uses existing technologies for floating concrete bridges and runways, such as Washington’s SR 520 and Japan’s Mega-Float.
Now with the emergence of microgrid technology in critical markets, electrical power system modeling, analysis and simulation has become more critical in the design and operation of data centers. Hence, it is crucial to make appropriate design decisions in the early stages of system planning to support energy efficiency strategies to significantly reduce total cost of ownership and improve the reliability of engineering and facility operations.
Today, the modern data center owner-operator expects an intelligent data center solution where design, analysis, validation and then on-line facilities are provided to provide a system with increased performance and lifecycle management. This process takes place from design to deployment to immediate operation and back to capacity planning.
Model-oriented design and operation
Lavan brings the method to the fore, codifying the intent of the design team to ensure that facilities perform exactly as intended or better. The power system model is validated for optimal performance at the beginning of the project (current, short circuit, protective device coordination, arc flash, reliability assessment, etc.). After the facility is operational, it continues to operate online by comparing “as-is” and “as-designed” data. It serves as the basis for real-time simulations and “what-if” studies, eg: capacity, upgrades, faults, reliability, etc… As the facility evolves over time, the model can be easily updated to server and act as a digital asset repository.
