Membangun Building Management Systems / Environmental Management Systems

Building Management Systems / Environmental Management Systems
A Building Management System (BMS) or a (more recent terminology) Environmental Monitoring Systems (EMS) is a computer-based control system installed in buildings that controls and monitors the building’s mechanical and electrical equipment such as ventilation, lighting, power systems, fire systems, security systems and many more. A BMS or EMS consists of software and hardware; the software program, usually configured in a hierarchical manner, can be proprietary, using such protocols as C-Bus, Profibus, and so on. Vendors are also producing BMSs that integrate using Internet protocols and open standards such as, BACnet, LonWorks and Modbus.
Building Management Systems are most commonly implemented in large projects with extensive mechanical, HVAC, electrical, and plumbing systems. Systems linked to a BMS typically represent 40% of a building's energy usage; if lighting is included, this number approaches to 70%. BMS systems are a critical component to managing energy demand. Improperly configured BMS systems are believed to account for 20% of building energy usage, or approximately 8% of total energy usage in the United States.

In addition to controlling the building's internal environment, BMS systems are sometimes linked to access control (turnstiles and access doors controlling who is allowed access and egress to the building) or other security systems such as closed-circuit television (CCTV) and motion detectors. Fire alarm systems and elevators are also sometimes linked to a BMS, for monitoring. In case a fire is detected then only the fire alarm panel could shut off dampers in the ventilation system to stop smoke spreading and send all the elevators to the ground floor and park them to prevent people from using them.
•         Illumination (lighting) control
•         Electric power control
•         Heating, Ventilation and Air-conditioning (HVAC)
•         Security and observation
•         Access control
•         Fire alarm system
•         Lifts, elevators etc.
•         Plumbing
•         Closed-circuit television (CCTV)
•         Other engineering systems
•         Control Panel
•         PA system
•         Alarm Monitor
•         Security Automation

Benefits of BMS
•         Good control of internal comfort conditions
•         Possibility of individual room control
•         Increased staff productivity
•         Effective monitoring and targeting of energy consumption
•         Improved plant reliability and life
•         Effective response to HVAC-related complaints
•         Save time and money during the maintenance.

Maintenance Companies
•         Ease of information availability
•         Computerized maintenance scheduling
•         Effective use of maintenance staff
•         Early detection of problems
•         More satisfied occupants

Additional Benefits
•         Data is consolidated onto a single system to improve reporting, information management and decision-making. Integrating and managing the HVAC, energy, security, digital video and life safety applications from a single workstation allows facility-wide insight and control for better performance.

Building/Environmental Management Systems
Buildings are constantly affected by changing temperature, humidity and occupancy that impact performance, comfort and safety. As a result, owners are continually challenged managing their proprietary HVAC systems seamlessly and reliably.

Therefore it becomes critically important to provide owners with open Building Management Systems that use real time data to monitor and control services such as heating, ventilation and air-conditioning, ensuring they operate at maximum levels of efficiency and economy. This is achieved by maintaining the optimum balance between conditions, energy usage and operating requirements.
Klasys-Tech Limited’s BMS solutions are installed on customer premises and are fully customizable. Whether you choose a more robust PLC controlled BMS/EMS it will improve energy efficiency, comfort, security, and safety of buildings over Central Control platforms. Cost saving solutions engineered to reduce the energy to cool and the energy to reheat building air.
With cooling temperature reset control you can achieve additional energy savings through lower refrigeration and re-heat costs.
Reduce costs by controlling room temperatures and air changes by managing the air handler pressure/flow control set points more effectively.
Integration expertise across numerous platforms provides flexibility in choosing the right solution to meet your requirements.
KlasysTech’s Building Automation personnel have the knowledge and experience to plan and install AKCP and OTHER BMS/EMS solutions that will help to integrate the various systems of the building including that of access control, heating, cooling, and ventilation, as well as lighting, life safety systems, utility monitoring, and security systems under one common operator control. This also means increased visibility, lower maintenance costs, manpower reduction, and quicker response times.
Sustain, improve and innovate your building automation systems with certified support services.
Controllers, networks, field devices, utilities management software, remote/alarm monitoring, and system back-up require service, upgrading and support. Managing the BMS/EMS lifecycle through planning, engineering and maintenance requires commitment, knowledge and skilled resources. Whether you choose to perform these functions internally, or turn to JMP – choosing your engineering and maintenance team to support your BMS/EMS is an important pre-requisite to achieving your goals.

Building automation is the automatic centralized control of a building's heating, ventilation and air conditioning, lighting and other systems through a Building Management System or Building Automation System (BMS/EMS). The objectives of building automation are improved occupant comfort, efficient operation of building systems, and reduction in energy consumption and operating costs, and improve life cycle of utilities
Building automation is an example of a distributed control system - the computer networking of electronic devices designed to monitor and control the electronic, mechanical, security, fire and flood safety, lighting (especially emergency lighting), HVAC and humidity control and ventilation systems in a building.
BMS/EMS core functionality keeps building climate within a specified range, provides light to rooms on an occupancy schedule (in the absence of overt switches to the contrary), monitors performance and device failures in all systems, and provides malfunction alarms to building maintenance staff. A BMS/EMS should reduce building energy and maintenance costs compared to a non-controlled building. Most commercial, institutional, and industrial buildings built after 2000 include a BMS/EMS. Many older buildings have been retrofitted with a new BMS/EMS, typically financed through energy and insurance savings, and other savings associated with pre-emptive maintenance and fault detection.
Almost all multi-story green buildings are designed to accommodate a BMS/EMS for the energy, air and water conservation characteristics. Electrical device demand response is a typical function of a BMS/EMS, as is the more sophisticated ventilation and humidity monitoring required of "tight" insulated buildings. Most green buildings also use as many low-power DC devices as possible, typically integrated with power over Ethernet wiring, so by definition always accessible to a BMS/EMS through the Ethernet connectivity. Even a passive house design intended to consume no net energy whatsoever will typically require a BMS/EMS to manage heat capture, shading and venting, and scheduling device use.
