Building Automation & Control

Today's healthcare providers face a daunting challenge: sustaining or improving patient care levels despite shortages of clinicians and nurses, increasing competition, and financial pressure.

During the energy crisis of the 1970’s there was a sea-change in the building industry when it paid more attention to the idea of conserving energy and introduced the terms Building Management System (BMS) and Building Automation System (BAS). Continuing rising energy prices and carbonreduction issues have also further spurred the development and deployment of BMS in recent years. However, the early systems were bulky, not user friendly, unreliable, and very expensive. With the advent of computerization, BMS analog signals became digitized so as to be communicated over long distance as well as facilitating the building management process these issues became less.Due to the multiple many management functions and wide range of expertise, modern BMS is quite complex. Successful building management not only needs to link to a multitude of devices but also take account of the suitability of the software for the intended application. Equipped with a web browser-based software package for human-machine interfaces (HMI) and supervisory control and data acquisition (SCADA) which provides automated, centralized and unattended management with a high degree of electronic accuracy, the BMS can fully control the building’s mechanical and electrical equipments and thus effectively monitor energy consumption so that it provides a comfortable, safe and secure environment.Property management is facing various and complex challenges and reducing operating costs have become increasingly important for building owners. As a result, a growing number of new and refitted buildings are being designed to use less energy and focus on the building’s performance. A System Integrator was helping a builder implement advanced BMS for its newest construction project in a creative park in Asia. The construction, a 14-storey building with four underground floors, covers an area of nearly one hundred thousand square meters and contains three distinct sectors - shopping mall, hotel guest room floors and office floors. In order to provide optimal energy management, this BMS needed to be capable of monitoring and controlling a variety of facilities, including air conditioning, power system, plumbing system, fire system, ventilation, elevator, lighting, garden watering and so on. Meanwhile, using one system with an adequate number of nodes in a main control room to manage three different places was a key requirement but each place had to have their own dedicated system and can be controlled independently without mutual interference so as to saving the implementation costs. Due to the need to monitor many areas, there would be tens of thousands of detection points, and the new system also needed to offer remote control capabilities so that building managers or patrol staff can view the status of various facilities in real-time and deal with issues using handheld or mobile devices.

Fast food chains like McDonald's seek to manage labor and energy costs along multiple nodes of their supply chain. One place where all the challenges of running these restaurants converge is the kitchen. In fact, the kitchen is the ideal place where energy can be saved, monitored and improved. The toughest part about effecting changes in the kitchen though is the fact that these buildings are often old and difficult to upgrade.
