About this good practice

Because of energy lossess, it is legally mandated to monitor energy and water consumption in buildings through the Energy Management Information System (EMIS). Each public sector institution must appoint an expert (whether an employee or hired third party) responsible for inputting and monitoring consumption data in institutional buildings. Most of the data is directly transmitted to EMIS by distributors and suppliers (referred to as Automatic data). In cases where automatic data isn't available, the appointed individual must manually input consumption data. Every user (i.e., appointed person) receives free training (provided by APN) on how to operate within EMIS, along with a unique username and password for system access. Given that EMIS encompasses over 20,000 buildings, users are granted visibility solely to buildings within their institution, ensuring restricted access. Only system administrators have comprehensive access to EMIS data. EMIS is under the ownership of the Ministry of Physical Planning, Construction, and State Assets. Public sector institutions can access consumption data from EMIS, whether for the entire country, a county, city, the entire local/central administration, or an individual building. Private sector entities or individuals must obtain permission from the data owner (i.e., the public sector institution) to gain insight into consumption data. An algorithm for calculating energy savings post-energy renovation will soon be integrated into EMIS.

Resources needed

cca. 100.000€ for the set up, transfer knowledge and one year of maintenance.

In Croatia there are 6 system administrators (in APN). EMIS has about 6,500 users who have been appointed to monitor spending on public sector buildings, and who have received training on how EMIS works. (€370,000/year).

Evidence of success

Savings in energy consumption of cca. 5% on an annual basis due to a change in user behavior (renovated objects excluded).
EMIS monitors the consumption of over21,500 public buildings in Croatia, 24,000 public lighting facilities. We have data on monthly consumption from 42,000 metering points in public buildings from 8.1 million accounts. We have over 83 million automatic readings from smart meters. EMIS is already being used in Hungary, Bosnia and Herzegovina, Serbia and Malesia.

Potential for learning or transfer

There are several aspects potentially interesting for other regions to learn from:
- The legal mandate for energy monitoring in public sector buildings.
- Structured data input through appointed individuals.
- Provision of free training for EMIS users.
- Implementation of access controls.
- The planned integration of an energy savings algorithm.
However, challenges in transferring this practice may include variations in legal frameworks and resource requirements. Nonetheless, given the effectiveness of the EMIS system, it could serve as a valuable model for regions seeking to enhance energy management in their public sector.
