Energy efficiency and impacts to climate change
Armin TeskeredzicMechanical Engineering Faculty

Shift in philosophy from ESD to EED!
From energysavings tocap consumption!
ESD prescribes the target in terms of relative amount of final energy (3% intermediate and 9% final target)!
EED prescribes the limits (cap) in terms of absolute amount of primary and/or final consumption!
Cap consumption
How the targets for EnC in 2020 are set?
PRIMES modelUsed for EnC6!
SMK – Serbia, Montenegro & Kosovo* modeled together!
Ukraine & Moldova joined Energy Community latter!
Target was to prescribe cap consumption for EnC8!
PRIMES modelUsed for EnC6!
IEA – Energy balance for 2012 used to estimate the ratio of PEC in UKR+MOL vs. EnC6!
First the PEC was needed to be estimated for UKR & MOL!

How the targets for EnC in 2020 are set?
𝐏𝐄𝐂𝐄𝐧𝐂 = 𝟐𝟑𝟑 𝐌𝐭𝐨𝐞
EnC 8 estimated primary energy consumption in 2020 using PRIMES!
Primary and final energy consumption caps!
20% savings
𝐏𝐄𝐂𝐄𝐧𝐂 = 𝟏𝟖𝟕 𝐌𝐭𝐨𝐞
𝟏𝟖𝟔, 𝟓 𝐌𝐭𝐨𝐞
𝐅𝐄𝐂𝐄𝐧𝐂 = 𝟏𝟑𝟑 𝐌𝐭𝐨𝐞
Preliminary estimations of PEC for individual countries! EnC well prepared for keeping the consumption below cap!
Primary and final energy consumption caps!
Primary and final consumption caps - Macedonia!
4% annually!
8% annually!
Macedonia will not reach the cap consumption!!!
• Current status and future development presented in strategic EU 27 document Heat Roadmap 2050,
• Analysis of baseline conditions year 2010!
• Sector development vision presented by 2030. & 2050. godine (science & private business hand in hand)!
Facts & Figures:6000 DH systems in EU!60 million people connected to DH!Market share of DH = 12%
Importance of new EE directive (example DH)!
4 Generations of DH systems
1G: Steam heating;t < 200O C
2G: Cogeneration;t >100O C
3G: Compact substations., consumption based, RES;
t < 100O C
4G: LTDH, Optimal mix with RES, EE demand side;
t ≈ 70O C
Importance of new EE directive (example DH)!
Platform for information exchange between different policy levels!
Evidence based monitoring tool (individual measures and programs)!
Long term vision – tool for strategic planning and monitoring!
Existence of local/municipal EE or CO2 reduction plans (SEAP, MEEAP)!
NEED FOR SIMPLE, INNOVATIVE AND COST-OPTIMAL MONITORING SOLUTION!
