Software that would provide functionalities of supporting and planning investments into EE projects and functionality of M&V of energy savings
In order to establish a more integral solution for energy management of its own buildings, the City of Zagreb together with Končar – Electronic and Informatics Inc developed its own Energy Information System (EIS) software. Although an energy monitoring system already exists on national level (called ISGE) the City decided to make a more complex and comprehensive software that would provide additional functionalities such as:
• Support in planning investments into energy refurbishment and monitoring refurbishment projects (measurement and verification of energy savings);
• Interconnectivity with smart meters subsequent to creation of data bridges, which enables consumption monitoring on a daily basis;
• Early detection and alarming in case of breakdowns, unexpected events and poor energy performance of buildings.
Monitoring and verification of energy savings through mart meters and EIS is particularly important for those funding sources (HBOR-EIB EEFF 2007 facility) that require verification of building’s energy savings through actual measurement of energy consumption after the refurbishment. Due to better energy management of public buildings the City can easily check whether consumption targets from Sustainable Energy Action Plan (SEAP) are being met and intensify its efforts if it is lagging behind expected progress.
Second phase of EIS software development will include modules for making energy efficiency investment scenarios, cost assessment and cost control report
Evidence of success
- Analysis and monitoring activities about critical consumption periods for all buildings within the system;
- Alerts responsible persons for taking some actions respecting the severity of recognized event avoiding extreme and unwanted energy and water consumption costs and reducing overall energy consumption of all buildings up to 3%;
- 957 public buildings connected to the system;
- all buildings are equipped with smart meters and remote reading of energy consumption.
Energy management tools for public buildings are quite common but expensive. EIS software was developed with an international corporation and therefore is not an open source, freely licensed software. However, the basic concept and scheme of the software can be had and freely distributed.
Potential for learning or transfer
EIS enables simplified energy and water consumption and costs data access as well as easy graphical and tabular data representation and reporting from conducted analysis. Part of functionalities also includes a simple user interface for local energy efficiency plans data preparation and reporting.
Monitoring for changes in energy performance is important to evaluate the effect of improvements that have been made and to provide evidence of progress towards improved energy savings.
