Summary of the TRACE City Energy Efficiency Diagnostic Study for Cluj-Napoca, Romania

Core Content

The TRACE (Tool for Rapid Assessment of City Energy) diagnostic study was conducted to evaluate the energy efficiency of Cluj-Napoca, Romania, as part of the Romania Regional Development Program. The study aimed to identify key sectors for energy efficiency improvements and to provide actionable recommendations for local authorities to enhance the city's energy performance.

Main Objectives

• Assess the energy use in six key sectors: urban transport, municipal buildings, water and wastewater, solid waste management, public lighting, and power and heat.
• Identify energy-saving potential and prioritize sectors based on cost savings and local authority influence.
• Provide recommendations for energy efficiency improvements that are practical and implementable.

Key Sectors and Findings

1. Urban Transport

• Energy Spending: $64,000,000
• Potential Savings: $4,500,000
• Recommendations:
  • Develop non-motorized transport modes (e.g., bike lanes).
  • Implement parking restraint measures.
  • Introduce traffic restraint measures.
  • Optimize traffic flow through signal optimization and information systems.
  • Expand public transport to the wider metropolitan area.
  • Introduce e-ticketing and energy-efficient rolling stock.

2. Municipal Buildings

• Energy Spending: $3,800,000
• Potential Savings: $1,400,000
• Recommendations:
  • Conduct audit and retrofit of municipal buildings.
  • Implement a benchmarking program for building energy performance.
  • Focus on educational facilities for rehabilitation.

3. Public Lighting

• Energy Spending: $1,400,000
• Potential Savings: $400,000
• Recommendations:
  • Conduct a city-wide integrated public lighting assessment.
  • Audit and retrofit street lighting systems.
  • Implement a street lighting timing program based on activity and weather conditions.

4. District Heating

• Energy Spending: $18,000,000
• Potential Savings: $6,900,000
• Recommendations:
  • Improve district heating network maintenance.
  • Address leakage and insulation issues in the system.

Key Challenges

• District Heating System: Old and inefficient infrastructure, with significant leakage and heat losses.
• Traffic Congestion: Increasing number of private cars and lack of adequate parking and road infrastructure.
• Energy Costs: High and rising costs of thermal energy, prompting many residents to disconnect from the district heating system.
• Public Transport: While well-developed, there is potential for further improvements in efficiency and accessibility.

Key Recommendations

• Non-Pedestrian Network Development: Expand bike lanes and implement a "Park and Ride" system to promote multimodal transport.
• Public Transport Development: Introduce new energy-efficient buses, extend the tram network, and implement e-ticketing.
• Traffic Flow Optimization: Use technical solutions and information systems to reduce congestion.
• Traffic Restraint Measures: Limit private vehicle access and introduce "no driving days" to reduce emissions.
• Municipal Buildings Audit and Retrofit: Conduct a full audit and prioritize energy efficiency upgrades.
• Public Lighting Audit and Retrofit: Implement timing programs and upgrade to more efficient lighting systems.
• District Heating Network Maintenance: Focus on repairing and modernizing the system to reduce losses and improve efficiency.

Importance of Urban Planning

• Urban planning significantly impacts energy efficiency.
• Compact and dense urban development reduces the need for extensive infrastructure and encourages sustainable transport modes like walking and cycling.
• The study highlights the importance of integrating spatial planning considerations into energy efficiency strategies.

Methodology

• TRACE consists of three main components:
  1. Energy Benchmarking Module: Compares key performance indicators (KPIs) across peer cities.
  2. Sector Prioritization Module: Identifies sectors with the greatest energy and cost-saving potential.
  3. Intervention Selection Module: Provides a "playbook" of energy efficiency measures for each sector.
• The tool is user-friendly, low-cost, and allows for a quick assessment of energy performance and recommendations.

Conclusion

Cluj-Napoca has shown significant development in recent years, becoming a key economic and technological hub in Romania. However, the city still faces energy efficiency challenges, particularly in urban transport and district heating. The TRACE tool has been instrumental in identifying these challenges and providing targeted recommendations to improve energy efficiency. The study emphasizes the need for a holistic approach, combining data-driven analysis with strategic urban planning and policy implementation.
