Summary of "Scaling Up Energy Efficiency in Buildings in the Western Balkans"

Core Content

This document outlines the importance of improving energy efficiency (EE) in the residential sector of the Western Balkans, identifies the key barriers to implementation, and presents various approaches and case studies to address these challenges. It also provides a roadmap for achieving energy efficiency targets in line with the National Energy Efficiency Action Plans (NEEAPs).

The residential sector in the Western Balkans is a major energy consumer, accounting for 28–32% of total final energy consumption, which is slightly higher than the EU average of 27%. EE measures such as insulation, heating system upgrades, and efficient lighting can reduce consumption by up to 9%, with payback periods typically under 8 years. These measures are crucial for reducing the burden of energy costs on households, especially as energy pricing becomes more rationalized.

Main Barriers to Energy Efficiency

The document identifies the following key barriers:

• Pricing barriers:

  • Energy subsidies distort prices and reduce the incentive for EE.
  • Absence of consumption-based billing leads to inefficient energy use.
  • Heating may become unaffordable for low-income groups due to rising tariffs.
  • High financing costs due to limited collateral and poor HOA legislation.

• Technical barriers:

  • Lack of metering in DH and central heating systems hinders accurate energy use tracking.
  • Poor building maintenance increases the cost and difficulty of EE implementation.
  • Underheating reduces the potential for cost savings.
  • Many apartment buildings lack central heating and DH connections.
  • Limited access to centralized DH water systems hampers the adoption of efficient systems.

• Legal and regulatory barriers:

  • Inadequate building codes and enforcement reduce EE implementation.
  • Decentralized ownership and weak HOA legislation complicate decision-making and financing.
  • Lack of legal structures for HOAs makes it difficult to implement EE measures collectively.

• Information barriers:

  • Low consumer awareness of EE opportunities.
  • Limited knowledge about energy use and consumption patterns.
  • Lack of quality standards and certifications for EE materials and appliances.

Approaches to Remove Barriers

Governments and institutions have implemented various approaches to remove these barriers, categorized into four main types:

• Financial mechanisms: Subsidies, loans, and price fluctuations are used to stimulate EE measures.
• Fiscal mechanisms: Taxes are leveraged to finance or support EE activities.
• Delivery mechanisms: Specific assistance or legal obligations are used to promote EE.
• Institutional mechanisms: Public institutions develop and manage EE programs.

These mechanisms are often used in combination, with financial and fiscal tools relying on delivery and institutional support for effective implementation.

Key Lessons Learned

• The implementing agency and delivery channels should be structured to maximize the reach and impact of EE funding.
• Administrative burden should be tailored to the target segment.
• Standardization of supporting tools is a success factor for smaller projects.
• Incentives must be tailored to local market conditions but should be clearly linked to long-term commercial growth.
• Incentives should support integrated projects that offer substantial savings.

Roadmap for Improving Energy Efficiency

The following steps are recommended to improve EE in the Western Balkans:

1. Implement financing incentive schemes for single-family houses including stoves.
2. Increase awareness and establish EE information centers.
3. Issue new building codes aligned with EU standards.
4. Implement building-level DH metering.
5. Improve HOA legislation to allow majority investment decisions through borrowing.
6. Rehabilitate DH systems to reduce losses and expand coverage.
7. Initiate transition to consumption-based billing for central heating.
8. Request building certificates and appliance standards and labeling.
9. Implement financing incentives for apartment buildings.
10. Implement EE incentives to regularize illegal housing.
11. Install apartment-level heating-cost allocators and thermostatic radiator valves (TRVs).

Case Studies and Examples

• Polish THERMO Modernization Fund: A successful grant and subsidy program that targets building refurbishment and energy efficiency improvements. It is supported by state-owned banks and ministries, and requires energy audits and financial analysis for eligibility.

Conclusion

Improving energy efficiency in the Western Balkans is essential for enhancing energy security, reducing costs, and supporting economic growth. While the region has significant potential for energy savings, the implementation of EE measures is hindered by multiple barriers. A combination of financial, fiscal, delivery, and institutional mechanisms is needed to overcome these challenges. The roadmap provided offers a structured approach to achieving EE targets, and lessons learned emphasize the importance of tailored incentives, effective delivery channels, and regulatory improvements.
