3. Establish the process of continuous improvement of energy
efficiency and sustainable management of energy resources
through systematic monitoring and analysis of energy
consumption data (monthly, weekly, daily), with the goal to know:
WHERE is energy consumed (office buildings, hospitals,
schools, courts, universities…)
HOW do we consume energy (HVAC systems, domestic hot
water, lighting, …)
WHICH energy sources do we consume (gas, fuel oil, wood,
heat, electricity, water)
HOW MUCH energy is consumed and what are the costs
WHO is responsible for energy management
WHAT we can do to increase energy efficiency
On the local, regional and national level:

6. • Energy efficiency (EE) part of legislative only in
words
• Lack of awareness, capacity and knowledge,
(especially in public sector) to identify, prepare and
implement EE projects
• Lack of clear organisational structure and
infrastructure to develop and implement EE projects
and manage energy
• General attitude in public sector that: „Energy
expenses are fixed costs, cannot be influenced and
are paid by „someone else”.”
Barriers?
7. • Energy Efficiency master plan 2008-2016
• Energy strategy
• First National Energy Efficiency action plan (2008-
2010)
• Second National Energy Efficiency action plan
(up to 2013)
• Law on Efficient end use of Energy
• Several others sub laws and technical documents
Technical assistance to Ministry of Economy in development of
existing and new strategic documents and legal framework

Web based application – main tool for continuous gathering of
energy usage data in buildings
Enables easy analysis and interpretation of energy and water
usage data on local, regional or national level from one central
place.

15. Capacity:
Development of human resources (knowledge and experience)
needed for SEM and implementation of EE improvement projects
Process:
Established operational organisational structure for SEM on
national, regional and local level
Tool:
Developed and established national Energy Management
informational system – EMIS
Result:
Established base for continuous and systematic energy
management in Croatia

16. Estimated savings for all objects in EMIS (absolute values)
Year Energy usage (kWh) Savings (EUR) Emissions CO2 (t)
2011 69.558.000 4.300.000 17.826
2012 69.437.000 4.840.000 19.126
Estimatipon with HDD correction (w/o correction of electical energy)
2011 106.368.000 6.260.000 26.493
2012 141.830.000 8.700.000 19.079 6,40%
Model:
• 1540 analysed objects, cca. 1.6 million m²;
• „Locked” bills for 5 years (2008.-2012.)
• Baseline year 2010.g., savings in 2011.g. i 2012.g.
• Energy usage normalizes according to heat degree days – HDD
• Calculated savings 49.420.000 kWh; more than 2.6 million EUR
Model extrapolated on all objects in EMIS (cca. 8.2 mil. m²)
Analysis of achieved savings
17. • Total estimated saving from 2010. till end of 2012. is cca.
15 million EUR – cca. 6,40% yearly
• Assuming same trends as in 2012., saving until
September 2013. is cca. 20 million EUR
• Savings are achieved with very little implemented projects
of complete building reconstruction!
• Potential of savings after project implementation is huge,
up to 30 – 50%!
• To tackle this potential, ministries are starting national
investments programmes for buildings retrofits.
Analysis of achieved savings
18. Energy import and costs
GDP u CRO 2011.
334 billion kuna
(44 billion €)
Total energy consumption in CRO 2011.* 384 petajoula (PJ)
out of which from import** 74%
Energy expenses in Croatia 2009.
50 billion kuna
(6,5 billion €)
15% BDP
What are the potentials?
Data source: Publication: Energy in Croatia 2011, EIHP. 2012
* - eng. Total Primary Energy Supply – Cro. Ukupna potrošnja energije prije transformacija
** - Energy import (Cro. Količina uvezene energije) u 2011. is 283 PJ. Energy export (Cro. Količina izvezene energije) u 2011 is 88 PJ. Difference 195 PJ
Assumption is that all imported energy is used in Croatia, in that case import share is 74%.
if we deduce exported energy that import share is 51%
19. Energy expenses in Croatia 15% BDP
Energy expenses in Croatia 2009.
50 billion kuna
(6,5 billion €)
Out of which in cities 50%
Or
25 billion kuna
(3,25 billion €)
Savings potential 30%
or
7,5 billion kuna
(1 billion €)
= 2,25% BDP
