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.
What is BMS
central controlling facility automate and take control of various operations manage all the
systems coordinate the various systems provide a comfortable working environment in an
efficient way. Its purpose is to control, monitor and optimize building services e.g., lighting
heating amp cooling security audiovisual and entertainment systems ventilation and climate
control time amp attendance control and reporting

BMS AND ENERGY SAVINGS With the usage of various building automation techniques the
energy efficiency is possible With the help of occupancy sensors provided in various areas of
the building. thereby leading to huge energy savings . the service plants can be brought into
operation only when needed and also to the optimum.
Create a sense of habitability through air movement. ventilation and slight temperature
variation. Smoke detector.BMS AND BENEFITS General BMS improves quality of built
environment. Allow the occupant to control and modify conditions to suit individual
preferences. Fire alarm and Fire sprinkler. while allowing great savings in energy
consumption Security and Life safety systems With the introduction of the various security
and life safety systems like Smart Access control. the environment can be made much easy
and fear free to work with Mechanical systems Provide an acceptable level of temperature
and humidity and safe guard against odours and indoor air pollutants. efficiency of

openly transmitted. Bank. whether it is a high security area such as a Hospital. such as
banks. CCTV is often used for surveillance in areas. School. CLOSED CIRCUIT

video cameras to transmit a signal to a specific. casinos. limited set of monitors. objects can
be tracked automatically ACCESS CONTROL SYSTEM Controlling access to any premise is
of vital importance at present. Modern CCTV cameras use small high definition color
cameras that can not only focus to resolve minute detail. or any common building such as an
Insurance Office. though it may employ point wireless links. but by linking the control of the
cameras to a computer. or Department store. Airport.
Smoke detectors are commonly classified by their mode of operation. Ionization Smoke

DETECTION SYSTEM Smoke is often the first sign that the fire is occurring. therefore an
automatic detection system based on smoke detectors is a valuable tool in the early dection
of fire.There arePortrait ID System.

Detectors Photoelectric smoke detectors use light to detect visible smoke particles produced
by burning material Fig Smoke sensor .
its service is invaluable. . utilizing a fusible link. hotels etc. a portion of which melts. Fire
sprinklers can be automatic or open orifice type. More than extinguishing its very important to
control it. FIRE SPRINKLER SYSTEM General Fire sprinklers are very useful in
extinguishing the fire before it spreads out. Especially in libraries. office buildings. Automatic
fire sprinkler Automatic fire sprinklers operate at a predetermined temperature. or a frangible
glass bulb containing liquid which breaks. allowing the plug in.

But all these are operated and controlled manually in general. . supplement the indoor
comfort to a great extent. At the same time some artificial intelligent systems like Occupancy
Sensors. airconditioners etc. Mechanical fans. desert coolers.INTELLIGENT COMFORT

whole year. can be used to sense the temperature increase and the presence of occupants
to decide comfort level required to achieve the optimum conditions. Temperature Sensors

lighting systems are switched ON. lighting is switched OFF after the user adjustable time

SENSORS PIR Passive Infrared Occupancy Sensor turns lights on and off based on the
occupancy. When the PIR sensor detects a change in the infrared heat radiated within the
controlled area.

BMS AND ILLUMINATION SYSTEM Lighting up the building is an art. Any how we cannot
depend on artificial lights alone. With out proper illuminaton the entire space will look dull. It
will add up the running costs. Hence some methods to bring natural light inside the habitable
space shall be sort out. creating an uncomfortable working space. .
LIGHTING CONTROL With the help of a light dimming device its possible to control the
intensity of lights especially when its requirement becomes less. This can be made possible
by suitably integrating the lighting systems with the BMS through sensors by which it is also
possible to turn off the lights automatically when its not needed. Hence there is the economy
in using the building. . .
Passive InfraRed PIR Occupancy sensing In areas which are occupied intermittently. and
switch the light on or off accordingly. Different control systems exist. again timebased control
and optimizer parameterbased where a level of illuminance or particular use of lighting is
required. Light level monitoring this consists of switching or dimming artificial lighting to
maintain taskspecific light level measured by a photocell. in order to avoid lighting a large
area if only a small part of it needs light. Zones lights are switched on corresponding to the
use and layout of the lit areas. occupancy sensors can be used to indicate whether anybody
is present or not. . Time control to switch on and off automatically in each zone to a preset
schedule for light use.
As it gives optimum thermal amp lighting efficiency it will cut down the electricity bills. It has
changed the entire working environment leading to the increased out put and also reducing
the running cost to a certain extent.CONCLUSION In this st century with the advent of the
various artificial intelligent systems the work places became very cozy to work with. . With
the increase in demand of such systems the cost of these will become affordable as more
and more builders will be using such systems in future. But any how today the cost of such
equipments to make a building artificially intelligent is a costly means.
