Energy and water consumption data of building complex belonging to
Faculty of electrical engineering and computing (FEEC) are entered
from bills during period from 2007 – 2010 into the ISEMIC
application and some of the obtained graphs are presented below.
The first graph shows the share of
each energy type in total cost with
tax for each year. Next three graphs
show electricity, heat and water total
consumption of whole complex of
FEEC for each year. It is also
possible to view total cost with tax,
monthly consumption and monthly
cost with tax for each energy type.
2. Goal of the project
This project has a goal to develop a software system called ISEMIC
for utilizing energy consumption measurements, both from smart
meters that can capture real-time data and traditional measurement
devices, subsequent data processing and analysis to facilitate, upgrade
and eventually replace the currently used energy management system.
Data on buildings, energy and water consumption over last few years
shall be entered into the ISEMIC database by each project partner as
well as they shall establish smart metering infrastructure and connect
it with the ISEMIC web application.
3. ISEMIC application
Electricity consumption
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.
Next graph shows monthly CO2
emissions during period from 2007 2010
caused
by
electricity
consumption. It is also possible to
view monthly CO2 emissions caused
by consumption of other energy
types.
Water consumption
More grained energy
and water consumption
data will be available
after the establishment
of
smart
metering
infrastructure which is
currently in conduction.
Alpha version of ISEMIC web application is developed and installed
on server; it can be accessed by following the link:
http://161.53.66.25:8080/IsemicIntro/.
ISEMIC architecture has three
levels:
1. Web browser on the client side
as user interface tool;
2. Apache Tomcat as servlet
container;
3. Oracle database as data storage
This flowchart shows the procedure
of setting energy efficiency targets
and their display on the graph.
Goals can be set as:
• a linear reduction (percentage);
• a new line based on selected
points of best efficiency or
• a new line formed on newly
defined basis points.
As the result ISEMIC generates
target line equation.
Heat consumption
5. Conclusion
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.
ISEMIC will enable:
• use of smart meters within energy management processes for the
first time in region, along with an analytical part which will enable
intelligent estimation of energy consumption based;
• continuous updating and maintenance of information on buildings
in the database;
• continuous entry and monitoring of consumption data for all types
of energy and water in buildings;
• calculation of consumption indicators by user-selected independent
variables entered in the database via preset parameters;
• monitoring and target setting for energy expenses and energy
savings for a building or a group of buildings;
• report creation according to user preferences or templates.
