  1. 1. BUILDING MANAGEMENT SYSTEM (BMS) OR BUILDING AUTOMATION SYSTEM (BAS) BY BUKAR ALI KIME
  2. 2. Title and Content • Introduction • What is BMS/BAS? • Characteristics of BMS • Structures And Component in BMS/BAS • Features of BMS • Benefit of BMS/BAS • Advantages & Disadvantages of BMS • Cost Analysis • Conclusion
  3. 3. Introduction • All Buildings have some form of mechanical and electrical services in order to provide the facilities necessary for maintaining a comfortable working environment. These services have to be controlled by some means to ensure comfort conditions. Basic controls take the form of manual switching, time clocks or temperature switches. Here if Building Management System (BMS), is introduced, we are able to get a comfortable working environment in an efficient way.
  4. 4. What is BMS • A building management system (BMS), otherwise known as a building automation system (BAS), 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, and security systems.
  5. 5. What is BMS : continue • Building management systems are most commonly implemented in large projects with extensive mechanical, and electrical 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. Properly configured BMS systems are believed to reduce up to 15% - 20% of the building energy usage.
  6. 6. Characteristic is BMS • BMS core functionality keeps building climate within a specified range, provides light to rooms based 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 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.
  7. 7. Component of BMS • Generally, the BMS term covers all control elements, including hardware, software, controllers, any linking network and central controllers. A BMS consists of; • Field layer level (field device), • Automation layer level (DDC controller) and • Management level (centralised workstation).
  8. 8. Field layer level (field device), • filed controllers get a single or stimulus which collect the information from the environment with the device are and respond from sensors, meters, switches or valves and transfers it to the next stage which is the Automation layer (DDC controller). Sensor Meter Switch
  9. 9. Automation layer level (DDC controller) • Automation Layer (DDC Controller) is running and communication. When this layer gets data from filed layer, they transit them to an interface (Web Browser), which can display all information. This component are; Micro-processor based, Pre-configured / freely programmable and Controls the HVAC equipment of the building HVAC control Micro-processor based Pre-configured switch
  10. 10. Management level (centralised workstation). • Management Level shall provide a uniform view to all systems through the open Building Operating System (BOS) platform. All the systems - controls of cooling, ventilation and lighting, consumption measurements, access controls, intruder alarms, fire alarms - shall be integrated with the BOS using device drivers.
  11. 11. FEATURES OF BUILDING MANAGEMENT SYSTEM (BMS) • Man machine interface • Security systems • User-friendly data presentations • Alarm management • Data lodging • Reporting
  12. 12. Man machine interface BUILDING MANAGEMENT SYSTEM INTERACT WITH THE CONNECTED TECHNICAL BUILDING EQUIPMENT. IT IS ALSO USER FRIENDLY FOR OPERATORS, ENGINEERS AND BUILDING MANAGERS BUILDING MANAGEMENT SYSTEM (BMS) ALSO PREVENT UNAUTHORIZED USES AND PROVIDE PASSWORD PROTECTION TO PROVIDE OPERATOR SPECIFIC ACCESS OR OPERATOR LOG SUMMARY. FEATURES OF BUILDING MANAGEMENT SYSTEM (BMS) Security system
  13. 13. FEATURES OF BUILDING MANAGEMENT SYSTEM (BMS) BUILDING MANAGEMENT SYSTEM GIVES AUTOMATIC GATHERING AND STORAGE OF DATA FROM THE FIELD EQUIPMENT FOR LATER ANALYSIS AND REPORTING IN DYNAMICALLY OR HISTORICAL FORM AND IN CUSTOMIZED CHARTS AND GRAPHS FORM AND ALSO IN TABULAR REPORTS BUILDING MANAGEMENT SYSTEM PRESENT CUSTOMIZED SUBSETS OF DATA’S, ACTUAL OR HISTORICAL STATE, AND ALSO EXPORT THE DATA’S AS A WORD OR EXCEL DOCUMENT FOR PRINTOUT. Data lodging BMS reporting
  14. 14. BENEFIT OF BUILDING MANAGEMENT SYSTEM (BMS) • 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 • Occupancy sensors allow automatic setback override during unoccupied periods as well as adaptive occupancy scheduling • Lighting controls reduce unnecessary artificial lighting via motion sensors and schedules as well as by controlling daylight harvesting louvers • Controllers save water and energy by controlling rainwater harvesting and landscape irrigation
  15. 15. ADVANTAGES AND DISADVANTAGES OF BUILDING MANAGEMENT SYSTEM ADVANTAGES • Higher levels of security and safety • Simplified operation for users and administrators • Simpler staff tracking • Reduced administration costs • Reduced system costs by sharing infrastructure • Information can be delivered to all interested parties in the manner they need. • Increased mobility DISADVANTAGES • Increased complexity of the system • Initial cost + the cost of installing a cooling system for the computers • Normal buildings last longer than intelligent buildings • Need a trained staff for it operations.
  16. 16. COST ANALYSIS : HOTEL CASE STUDY IN CYPRUS • The average cost to deploy a basic BMS is at least 6.00euro per square metre and can be as high as 16.00euro per square metre. Air Conditioning Lighting Catering Hotwater Other 0 5 10 15 20 25 30 35 40 45 50 Air Conditioning Lighting Catering Hotwater Other typical hotel annual energy consumption Series1 • For a 5000 sqm hotel it is 30,000euro for the cost of instalment.
  17. 17. COST ANALYSIS • According to statista portal the electricity prices for household end users in Cyprus semi-annually from 2017, the average electricity price for households was 0.18 euro cents per kWh. • According to statista 2017 a typical hotel comsume 10kw/h
  18. 18. 0.18euro cent x 10hour = 1.8 eurocent per kw/h 1.8 x 8760 = 15,768 euro kw/year 20% of 15,678 = 3,153.6 euro kw/year 0 5000 10000 15000 20000 25000 30000 35000 COST OF INSTALLATION ENERGY PER YEAR ENERGY SAVING PER YEAR 5 YEARS ENERGY SAVING ENERGY SAVING CHART COST ANALYSIS
  19. 19. CONCLUSION • A Building Management System (BMS) offers greater visibility and control of energy use. A fully integrated solution can have up to 84% of a building’s energy consuming devices directly under its control. The data it produces allows facilities managers to better analyse, understand, reconfigure and improve their site’s energy usage and costs, by having them presented in an organised and informative way.
