1. INTRODUCTION
Nowadays most of the people spend lot of time in offices.
Office environment should be leisurely so that the
employees can give their best as office environment
directly affects the working efficiency of
employees/workers. So comfort is must and it is needed in
office. In earlier decades technology at its best meant a fax
machine and an electronic typewriter; today it's an iPad
connected to the cloud solution. A smart office is a place
that makes life easy for employees and customers, which
empowers it and increases their ability to stay connected.
This is achieved by making use of various advanced
technology and different tools and solutions to improve the
efficiency of users. As the physical boundaries are being
bridged, a competitive and complex world focuses on
innovation and creativity is being developed. The world is
greatly experiencing the emergence of intelligent growth
zones so smart office- has fast become the need of the
hour.
A smart office is something that ensures the effective and
optimal utilisation of IT resources and physical
infrastructure. In other words, in today's generation of
information technology offices are automated. There is
need for transparent technological advanced environment.
Thus the office automation allows the systems to become
more transparent, it enables sharing of information more
openly, which creates an opportunity for making an great
impact across the functioning of the industrial sector and
business. The use of various communication tools in the
system and effective advanced automation, shows the
positive impact on the growth of company or any
organization and business over a period of time. The
elimination of internal reporting processes, i.e. in/out
timings of the workers by an open office arrangement is
the advantage of smart office. The productivity can be
increased through enhanced communication among team
members which affects in the result. A smart office is to be
designed to release full potential of employees and the
workforce. It’s not a miracle just innovative thinking and
new technology that best fits people’s needs. Office
automation among other things facilitates real time
communication and easy documentation.
Building sector is one of the main cause of the global
energy consumption. It consumes nearly one third of total
energy consumption. Smart building is like a smart home
that optimizes efficiency, comfort and safety by collecting
and analyzing sensor data intelligently. Modern buildings
contain complex mechanical devices, sophisticated control
systems and various features to improve the safety,
productivity of occupants.
A smart building can be considered a super system of
subsystems interconnected with building. The smart
building requires connectivity between all the systems and
equipments in a building. It helps building managers to
visualize information and make fast and precise decisions.
The smart building can be made by using various
strategies. Through a building automation or building
management system, the automatic centralized control of a
building's different sub-systems i.e. lighting ,heating,
ventilation and air conditioning, and other systems are
achieved. Objectives of building automation system are
improved efficient operation of building systems, occupant
comfort, and decrease in energy consumption and
operating costs, and improve life cycle of utilities.
Building architectures consumes lot of energy. Significant
amount of energy can be saved by managing the electric
consumption in commercial buildings. Because of these
issues, the concept of Smart office emerges. This design
concept of smart office can be applied to whole building,
i.e. smart office building which reduces the energy
consumption. Security plays a vital role in day to day’s
life. The advent of fast growing technologies makes users
to have high security systems. The systems should be
highly secured. These identification technologies include
ATM and other intelligent cards, user password based
systems, and many other. But unfortunately these systems
are unsecure due to hacker attacks, thefts, and forgotten
passwords. RFID is also been used in security purpose. But
the disadvantage of RFID is that it can be stolen or some
other person can also used that ID and enter. This is not at
all safe. In spite of all these shortcomings and malfunctions

the most efficient and reliable solution for security is the
biometric or fingerprint authentication based identification.
In this system, a comprehensive smart office system
concentrated lighting, heating, security; alarm system is
designed in order to save energy and to promote the
satisfactions of the employees. With a multifaceted
approach, Smart Energy Solutions achieves energy savings
that capitalizes on human behaviour. By recognizing the
fundamental role humans play in energy consumption, this
implemented system shows the way to reduce it.
2. RELATED WORK
Various research papers related to office automation and
smart automation systems are referred. Researchers have
put focus on different controlling systems, subsystems and
have controlled different parameters of smart office.
Various processing parameters and results of various
papers are discussed in this section.
Hang Li,In this system a comprehensive smart office
system concentrated on door-access, lighting, illuminating,
ventilating, heating, and reconfiguration is designed in
order to save energy and promote the satisfactions of the
employees[1].Catalian B. Et al, this system presents the
study on how it is possible to ensure the indoor office
comfort, indoor comfort is the important types of comfort
(visual, acoustic, thermal, air quality, etc.) and how each of
them could be analyzed. This system have discussed
thermal comfort[2].Pellegrino, A. et al, This system have
focused on some results that are aimed at being
developing an event–driven user-centric middleware. This
system have monitored and managed the energy
consumption in already existing public building. The
system was adopted and used in different building
construction.[3]. Gupta, S.K et al, In this system a
distributed solution which ensures that a consensus is
attained among all occupants, irrespective of their ideal
temperature preferences being in coherence or conflicting.
[4].
Gaspare Boscarino et al, This system presents a simulation
environment and day lighting control strategy to achieve
energy-efficient lighting while it also provides desired
lighting levels at the target points. The lighting strategy is
based on a self-tuning multivariable controller, which
maintains the illuminance levels at user-defined set-points
which improves the energy consumption due to artificial
lighting.[5] Kemal Akkaya et al, In this system the major
challenges are to achieve occupancy monitoring in a
minimally intrusive way, e.g., using the existing
infrastructure in the buildings. Also it does not require the
installation of any app in the users’ smart devices. To
develop effective data fusion techniques for improving
occupancy monitoring accuracy using different sources is
other challenge. This system surveys the existing works
multi-modal data fusion techniques for smart commercial
buildings and occupancy monitoring [6].
Shiquin Shen et al, This system proposes a novel mobility
simulation framework based on behaviour patterns for
office environments. Simulation time controller is the base
part, on which we model the structure of offices and define
behaviour patterns [7].Nati, M et al, This system presents
the outcomes of a study that examines human interactions
and mobility patterns in indoor spaces such as office
environments. An initial analysis of these traces provides
deeper insights into the encounter characteristics between
static infrastructure devices and human-held devices. The
presented findings also confirm that opportunities between
mobile devices derived from observations of infrastructure
devices can introduce significant errors into the modelling
of such encounters [8].
Tangjian Deng et al, A smart meeting room usually refers
to a working environment, which provides meeting
attendees with a highly effective information acquisition
and exchange space, with an aim to improve the working
and decision-making efficiency. System abstracts devices
spontaneous interoperations into three categories and
present design and implementation of a context-aware
spontaneous interoperation of information devices in
building a smart meeting room [9]. Giovanni Bettinazzi et
al has proposed a general method and algorithms to
interconnect residential smart buildings with smart grids.
Such integration system has the ability to deal with the
smart building to forecast its energy consumption; the
proposed method is able to learn to use of such information
to forecast the energy consumption and the building
occupants habits. For selecting the most appropriate
appliance usage scheduling it presents a method giving a
energy reduction request coming from the smart grid [10].
In the above mentioned systems parameters like
Temperature (Heating, ventilating systems), light are used.
Also in other papers the authors have focussed on single
parameter greatly. While in this system Smoke sensor is
used for fire alert and fingerprint identification module is
used for security purpose which is added.

3. SYSTEM DESIGN
Fig.1: Block diagram of smart office system
The smart office is designed for users comfort and leisure.
It works on automatic and manual mode. In automatic
mode the working of system will depend On/off conditions
of various sub-systems i.e. lightning and ventilating. The
block diagram of smart office system is showed in
Figure.1.It consists of various sensors attached to the
controller.
Motion sensor will detect the presence of any person. It
also counts the number of people entered in office. The
system will get activate only in presence of person.PIR
Motion sensor is used. Light sensor will detect the
presence of light. If light intensity increases or decreases
below or above some value, the bulb will glow. The
system will then automatically adjust the light intensity
according to the atmosphere.LDR is the sensor used. The
temperature sensor will sense the surrounding temperature.
If the temperature increase/decrease the fan will be ON.
LM 35 is the sensor used. Smoke sensor will detect for the
presence of smoke/fire. Alarm/buzzer will get activate in
presence of smoke/fire.MQ-3 is the sensor used. If there is
presence of smoke/fire call will be given to the Fire
extinguisher and to the service rooms that immediate
service can be provided. All the sensed data is send to the
ARM 11Controller.The data is displayed on LCD display.
This data sensed through different sensors is then send to
computer and is stored in Office’s database. This data is
then send to other computers in service room from where
the data is being monitored. The data can be controlled and
monitor from service rooms. Other computers are
connected to the main computer via Network switch. The
smart office data can be remotely monitored through
Android or any internet enabled device. Call will be given
to the office admin if there are any changes in the
parameters of office. If there is any accidental emergency,
the system calls the ambulance and message is send to the
service room.
3.1 Fingerprint Identification Module:
It is used for the security purpose. It can be placed at the
entry gate in office. It will contain the enrolled fingerprints
of all the employees. So only the enrolled persons (whose
fingerprints are enrolled) will be allowed to enter the
office. If any other person tries to enter, it will show no
match on LCD.

3.2 Alarm Security System
In this system, if there is presence of smoke above the
threshold value, the buzzer will be ON.As the buzzer will
be ON, with the help of GSM Module, call will be given to
the authorized user. So we will be come to know if there is
an emergency. The snapshot of incoming call on
authorized user is as shown in Fig.3.

6. RESULTS
Fig.5: Hardware structure
Fig.5:shows the complete structure of hardware of
proposed system. Which have used ARM lpc1769𝜇c,
Buzzer, relays, transformer, LCD display , Fans , LED
bulbs and sensors (Temperature, , Smoke, PIR and LDR
sensors).And for seeing the results of this system we need
one PC and personal mobile. By combined all these
elements made a new application for Smart automation for
office Environment successfully. We can see the results of
sensors on the LCD display and at the same time we can
continuously observed the same results on Wamp server of
the PC .Firstly, when give the power supply of the system,
we can observe the output on the LCD screen is the name
of project. Before start the micro controller, we should ON
the GSM modem and wait for its connectivity. As GSM
modem is connected, so we need to do ON the power
supply of ARM microcontroller. After connectivity of
GSM, we can see the results of all sensors on the LCD
display. This shows the system result on PC as
GUI(Graphical user interface).COM port have to be
selected. The GUI system settings can be changed. This
window has to be close before ending Eclipse software.
Fig.6:Snapshot of webpage.
This shows the sensors data on Webpage .It can be
attached to other PC’s in the service room. This data can
be viewed as it is on mobile screen also. For this we have
to enter the url of webpage on server.
7. CONCLUSION
The illuminating, lighting, heating, ventilating ,door
access, smoke detection systems are being designed.
Fingerprint biometric is used for security purpose. Other
person cannot enter the office area. Fire alarm system is
used. Whenever the threshold is crossed, Alarm will be
ON and call will be given on mobile in service room. The
smart office system in the system is based on an
independent smart office and then expanded to the whole
smart building. In this smart office system, two working
modes automatic mode and manual mode are use. The
manual mode is viewed as a supplement of the automatic
mode.
8. ACKNOWLEGEMENT
This study is useful for the smart automation systems for
office environment and in understanding the different
subsystems for office use by using ARM controller and it
is used to reduce the power consumption. It is also useful
in studying fully automated systems in office and industrial
sector.
9. FUTURE SCOPE
This system of smart office can be extended to whole
building. Energy consumption can be reduced to great
extent if this system is applied to whole building. As the
smart office is not only a product of modern technology,
but also a product that can save energy. This system can
be helpful to energy saving and employee´s satisfactions.
Comparisons between the real office environment power
consumption and smart office environment power
consumption should be made. And then comparisons
should be made under different methods.
