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.

5. 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.

7. 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.

8. 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.

10. 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).

11. 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

12. 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

13. 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.

17. 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

18. 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.

19. 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.

20. 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

22. 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.
