Summary of the TRACE City Energy Efficiency Diagnostic Study for Timisoara

Core Content

This document presents the findings and recommendations of the TRACE (Tool for Rapid Assessment of City Energy) diagnostic study conducted in Timisoara, Romania, in April 2013. The study focuses on energy efficiency improvements across six key sectors: urban transport, municipal buildings, water and wastewater, solid waste management, public lighting, and power and heat. The report was developed under the Romania Regional Development Program, funded by the European Union, and carried out by the World Bank in collaboration with the Ministry of Regional Development and Public Administration and local authorities in Timisoara.

Main Views and Key Information

Why a study on energy efficiency?

• The study was initiated by the Ministry of Regional Development and Public Administration to support the preparation of energy efficiency strategies for local authorities in the context of the 2014–2020 Programming Period.
• Energy efficiency is a critical priority for EU member states, particularly under the Europe 2020 strategy.
• The TRACE tool is a simple, low-cost, and user-friendly method to assess energy use and identify priority areas for efficiency improvements.

What is TRACE?

• TRACE is a diagnostic tool designed to evaluate energy performance in six sectors and recommend efficiency measures.
• It uses benchmarking algorithms to identify sectors with the highest energy savings potential, based on the level of influence local authorities have over these areas.

Advantages of TRACE

• It is quick to implement and cost-effective.
• It allows local authorities to prioritize energy efficiency interventions based on savings potential and feasibility.
• It provides a comprehensive overview of the city's energy performance.

Limitations of TRACE

• The tool provides general insights and does not go into detailed cost analysis for specific projects.
• It does not consider institutional or legislative factors that may impact the implementation of energy efficiency measures.

Boundaries of the Studied Area

• The analysis was limited to the center city of Timisoara, as collecting data from the entire metropolitan area would be too complex.
• The sector analysis and recommendations were developed at the metropolitan level, while the urban planning section was done at the city level.

Summary of Findings

Timisoara Overview

• Timisoara is a major transportation hub in Romania, located on Pan-European Corridor IV.
• It has a well-developed public transport system (trams, trolleybuses, and buses) and a functional non-pedestrian network.
• The city has increased its population by 0.5% since the 1989 Revolution, unlike most other Romanian cities.
• The water sector has been modernized, with metered connections and expansion of the network.
• Public lighting has been improved, with LED bulbs being tested along the Bega Channel.
• Municipal buildings have been renovated, especially in healthcare and education, and further thermal insulation is planned.

Key Challenges

• Traffic congestion and high fuel consumption are major issues due to the rising number of cars.
• District heating has significant potential for energy savings, but requires rehabilitation of the hot water pipes.
• Public transport needs modernization and expansion to increase usage and reduce reliance on private vehicles.
• Street lighting can be optimized with a timing program to reduce electricity consumption.
• Municipal buildings require benchmarking and retrofitting to improve energy efficiency.

Energy Efficiency Recommendations

Key Recommendations

1. District Heating Maintenance and Upgrade

   • Continue to invest in network rehabilitation to reduce losses in hot water pipes.
   • Improve the efficiency of the district heating plant.

2. Non-Motorized Transport Development

   • Expand pedestrian paths and bike lanes.
   • Encourage walking and cycling as alternative commuting methods.

3. Street Lighting Timing Program

   • Implement a lighting-timing program to reduce electricity consumption based on activity levels and weather conditions.

4. Public Transport Development

   • Modernize the public transport fleet and purchase energy-efficient rolling stock.
   • Develop dedicated bus lanes to bypass traffic congestion.

5. Municipal Buildings Audit and Retrofit

   • Conduct a benchmarking program to identify high-saving potential buildings.
   • Perform audits and retrofits to improve energy performance.

Conclusion

• Timisoara has made positive strides in energy efficiency, but there is still room for improvement.
• The TRACE tool has been successfully implemented to identify priority sectors and recommendations for energy efficiency.
• Urban planning plays a crucial role in achieving energy efficiency, as dense cities require less infrastructure investment and promote sustainable mobility.
• The study highlights the importance of collaboration between local authorities, public utilities, and private operators to achieve long-term energy efficiency goals.
