Introduction
In the residential and service sector,
information on energy and water consumption is
commonly only provided on a monthly or bi-monthly
basis. Frequently the recipient of the
information has no benchmark to assist in
determining whether consumption levels are normal
or excessive. This paper presents
implementation of ISEMIC model on Faculty of
Technical Sciences (FTS) in Novi Sad. This web
application connects processes of gathering data
on buildings and their energy and water
consumption, monitors consumption indicators,
detects all anomalies in time, sets energy
efficiency targets and reports energy and water
consumption savings. FTS first in Serbia
(educational sector) installed smart meters for
gathering information about energy and water
consumption. All the data are stored on SCADA
which is connected to ISEMIC application. This
concept of energy management enables huge
potential for energy and water savings on FTS.

Scope of Research

• Improving the efficiency of energy consumption is
  a central theme of any energy policy. Improved
  energy efficiency meets three energy policy
  goals
• security of supply,
• competitiveness and
• protection of the environment.
• Systematic energy management is a body of
  knowledge and skills based on an organizational
  structure that links people with assigned
  responsibilities, efficiency monitoring
  procedures and continuous measurement and
  improvement of energy efficiency. This body of
  knowledge must be supported by appropriate ICT
  for gathering, processing and disseminating data
  on energy consumption, energy efficiency targets
  and information.
• Intelligent Information System for Monitoring and
  Verification of Energy Management in Cities
  (ISEMIC) will be a software tool that connects
  processes of gathering data on buildings and
  their energy consumption, monitoring consumption
  indicators, setting energy efficiency targets and
  reporting energy consumption savings.

Scope of Research
ISEMIC is upgraded version of Energy Management
Information System (EMIS) in which an accent is
put on creating a network of people regularly
monitoring and manually entering consumption data
in EMIS via the web. Also, EMIS has no smart
meter input capability. These two missing
features are the focal point of ISEMIC
development.

Description of ISEMIC web application
ISEMIC is developed in Croatia. ISEMIC further
implements a newly developed methodology for past
energy consumption data analysis using regression
analysis, least square method, best-fit lines,
scatter trending, as well as setting and
cascading targets using correlation analysis and
risk analysis using probability distribution for
planning improvement measures. Regression
analysis shows how a dependent variable energy
consumption is related to the independent one
for example (production, temperature), by
providing an equation that allows estimating
energy consumption for the given temperature. The
relationship between production and energy
consumption in most cases is in linear form which
means that the relationship between the points in
the graph can be approximated by a straight line
and expressed by a linear equation (yaxb). If
constant values (a and b) are calculated by the
least square method the resulting line will go
through the center of data scatter and therefore
is called a best-fit line.

ISEMIC calculates energy savings in the same way
every day/month/year, and adds the
daily/monthly/yearly savings. Cumulative sum
(CUSUM) presents accrued differences for each
day/month/year, and is calculated by adding the
accrual from the previous day/month/year. CUSUM
graph expresses savings at any time and enables a
direct comparison with the target amount of
energy that should be saved.

Description of ISEMIC model on FTS Novi Sad

• FTS installed smart meters in building called
  Masinski institut (MI). There are six
  metering places one for electrical energy
  consumption, one for electrical energy production
  (PV panels), two for heat energy consumption and
  two for water consumption. Description of
  metering places (SCADA Preview) is shown on
  Figure.

Description of ISEMIC model on FTS Novi Sad

• In summary measure works as follows
• Clorius controller ISC2100 is the basis of
  everything. ISC 2100 belongs to a family of
  freely programmable controllers designed to be
  scalable from the small to the very large
  installations. ISC 2100 is well suited to control
  meters for heat, electrical and water consumption
  and can function as a PLC. It communicates with
  the Danfoss ECL300 controller placed in two heat
  substations (allows reading and setting the
  parameters of the controller). Inside of Danfoss
  controller is ECA 71 MODBUS communication module
  which makes it possible to establish a RS485
  communications with Clorius controller ISC2100.
  Reading values ??from the calorimeter MULTICAL
  66-CDE is achieved via RS232 communication
  (built-in communication modules), and value from
  the water meter DS TRP MID via pulse input.
  Clorius controller ISC2100 also communicates via
  RS485 communication with the network analyzer in
  the transformer station EEM-MA200. Inside of
  network analyzer EEM-MA200 is built RS485
  communication module. Temperature sensor ESM-10
  is installed in reference room and it measures
  current inside temperature. Clorius controller
  ISC2100 is connected to our Ethernet (LAN)
  network and communicates with the computer that
  is running SCADA applications (Wonderware In
  Touch 2012 SCADA system). It can be accessed to
  each controller by IP address from any computer
  in local network via a web browser, or from
  remote location if it is allowed to access the
  network from outside. The computer sends required
  reports (readings from metering devices) to the
  server in Zagreb. Data processing software
  (ISEMIC) is installed on that server.
• FTS from its resources and donor funds managed to
  make the first solar power plant (PV) to produce
  electricity. Photovoltaic filed makes two strings
  of 20 panels, connected in series, with
  individual nominal power of 240 Wp. PV inverter
  nominal output power is 8kW. Production
  information of electricity, as well as
  meteorological data conditions that prevailed
  during the electricity production are recorded,
  processed and stored on the SCADA system.

Results

• Energy and water consumption data of Masinski
  institute (MI) belong to Faculty of Technical
  Sciences (FTS) are entered from bills during
  period from 2009 to first half of 2012 into the
  ISEMIC application and some of the obtained
  figures are presented below.
• The first figure shows the share of each energy
  type in total cost with tax for each year. Next
  three figures show electricity, heat and water
  total consumption of MI for each year. It is also
  possible to view total cost with tax, monthly
  consumption and monthly cost with tax for each
  energy type.
• Next figures show monthly CO2 emissions and
  primary energy consumption during period from
  2009 to first half of 2012 caused by heat
  consumption. It is also possible to view monthly
  CO2 emissions and primary energy consumption
  caused by consumption of other energy types.
• More grained energy and water consumption data
  will be available after the establishment of
  smart metering infrastructure which will start
  from 1st of November 2012.

Conclusions
It is expected that ISEMIC will improve energy
efficiency in buildings, raise building users'
awareness of energy consumption and utilize
measurements from smart meters. Examples from
praxis show that introducing an energy
consumption monitoring system raises employee
awareness on energy expenditure, which leads to
5 of energy and water savings without any
additional investments in energy efficiency
measures. After full ISEMIC implementation and
implementation of some simple energy efficiency
measures it is expected that energy and water
savings will reach at least 10 of current
consumption expenses of all project partners.
The potential impact of this project is very
large and it would be a great example how
significant savings can be achieved by systematic
energy monitoring and management provided by the
use of ISEMIC. After successful project finish it
is expected that city, county or ministry will
show higher interest to connect public buildings
in their ownership with the ISEMIC web
application and start systematic energy
monitoring and management. Connection of private
buildings with ISEMIC is expected in further
future.
