|EMIS: 5 things you need to know
1. What is Energy Management Information System EMIS?
It is an on-line tool to analyse and manage energy and water consumption in buildings.
One can access it from a smartphone, a tablet, a laptop, a desktop or a server.
What kind of buildings? Any kind, but in this case, we’re talking public sector buildings. Those for which bills are paid from a public sector budget, from tax-payers’ money.
Energy is precious. Tax-payers money even more. So EMIS helps to monitor how it is spent.
2. Which three important things does EMIS help us know?
1. Where, when and what type of energy do we consume?
2. How much do we consume and who is responsible for it?
3. Where is the system most inefficient, and where is the space for improval and savings?
And if that weren’t good enough: EMIS makes visible CO2 emissions from buildings!
You can imagine that it’s easier to change bad habits when one sees the consequences of his/her behaviour directly than if they remained invisible, so this is really useful.
3. Why should we care?
The buildings sector typically consumes 40% of all primary energy consumption in a country.
The EMIS gives us possibility to quickly access and analyse data with an aim to optimise consumption, to quickly fix when something leaks or when a building overspends or over-consumes compared to other similar buildings. So it enables us to compare, to detect and to correct anomalies immediately.
An interesting example, from a prison: Early in 2011, the energy efficiency team in the Croatian Ministry of Justice was alarmed to abnormally high rates of water use at Lepoglava Prison.
Pumping water is energy intensive, so leaks waste both resources.
A probe of underground pipes quickly located a major break. Fixing the problem cost just $4,000, but saved the prison $225,000 per year in water losses.
Without vigilant monitoring provided by EMIS, the leak would have gone unnoticed.
4. How reliable is this information?
The meter-readers data get into the system on hourly, daily, weekly and monthly basis, so we can monitor consumption in real-time.
Data can be entered manually or automatically, they are inter-connected with other databases – those of energy suppliers and distributors.
Data received automatically from suppliers is good because human error on data-entry is close to nil.
Manual data entry entails human labour and a risk of human error but also helps to raise awareness of consumption and change in behaviour.
5. Has it made a difference?
In Croatia, the average annual energy costs make up to 15% of GDP. At least half of the primary energy supply is imported.
During 2010-2012, energy consumption dropped by almost 7% per year only due to the fact that it is regularly monitored through EMIS.
This generated savings of more then 49 million of kWh or more than 2.8 million USD in energy costs.
Add to that another 7 percent energy savings coming from “behavioural change” and some low-cost or no-cost management adjustments: total savings pile up to at least 30% in a relative short period of time.
Besides creating savings, it contributes to energy security, to CC mitigation and emissions reduction, to boosting jobs in (re)construction sector, to creating green jobs in energy efficiency solutions; and it improves in-door conditions.
Here are some more facts about EMIS:
In Croatia, EMIS:
• is in full use in 115 (of 127) cities, all 21 counties, all 20 ministries, 43 municipalities and 59 other public sector institutions.
• contains data from more then 11.000 buildings (out of 13.000 estimated total) with 2000 active user-accounts. Around 5,000 bills are entered into the system every week.
• As of 2012, has become a part of the national information system i.e. a mandatory tool for data collection and energy management in public sector buildings in the Republic of Croatia.
• In 2014 it was piloted and transferred to Serbia. As of 2015 the system was made mandatory by law in the Republic of Serbia, too!
• It’s also use in several municipalities of Bosnia and Herzegovina.
• There is a strong expression of interest coming from Russian Energy Agency in RF. Pskov region is on stand-by to implement it during 2016.
