Summary of the TRACE City Energy Efficiency Diagnostic Study in Iaşi, Romania

Core Content

This report presents the findings and recommendations of the TRACE (Tool for Rapid Assessment of City Energy) diagnostic study conducted in Iaşi, Romania, as part of the Romania Regional Development Program. The study focuses on identifying energy efficiency opportunities across six key sectors: urban transport, municipal buildings, water and wastewater, solid waste management, public lighting, and power & heat. The goal is to help local authorities develop strategies and action plans to improve energy efficiency and reduce greenhouse gas emissions.

Main Points

• Energy Efficiency Strategy and Action Plan: The first recommendation emphasizes the need for the local government to develop a comprehensive energy efficiency strategy and action plan, especially to meet the Covenant of Mayors goals and reduce emissions by 20% by 2020.
• District Heating: Identified as the sector with the highest energy savings potential, the district heating system in Iaşi requires maintenance and upgrading to reduce losses, maintain affordable heat prices, and regain market share.
• Non-Motorized Transport: Promoting walking and cycling is recommended to reduce private vehicle use and fuel consumption. Expanding pedestrian paths and bike lanes is encouraged.
• Parking Restraint Measures: Implementing "Park and Ride" facilities and increasing parking costs in the downtown area are suggested to manage traffic congestion.
• Traffic Restraint Measures: Limiting access to private inter-regional buses and introducing "no driving days" are proposed to reduce traffic and promote sustainable mobility.
• Traffic Flow Optimization: Enhancing traffic management through information systems and monitoring tools is recommended to improve traffic flow and reduce energy use.
• Public Transport Development: Continued modernization of the public transport fleet, expansion of dedicated bus lanes, and improving connectivity with neighboring areas are key to increasing public transport usage.
• Municipal Building Benchmarking: A comprehensive database of municipal buildings is needed to identify those with the highest energy savings potential, enabling targeted retrofitting and efficiency improvements.
• Municipal Building Audit and Retrofit: After benchmarking, a full audit of the building stock is recommended to guide resource allocation for energy efficiency upgrades.
• Street Lighting Timing Program: Adjusting street lighting based on activity levels and weather conditions can significantly reduce electricity consumption.

Key Sectors and Recommendations

Context and Challenges

• Iaşi, a regional growth pole in North-Eastern Romania, has transitioned from an industrial-based economy to an academic and service-based one.
• The city faces challenges in energy efficiency, including outdated infrastructure, high energy costs, and increasing traffic congestion.
• The district heating system is in need of significant rehabilitation due to aging infrastructure and high losses.
• Public transport is relatively efficient but requires further modernization and expansion.
• The city has made progress in replacing inefficient lighting and expanding water and sewage networks, but more work is needed to improve energy consumption across all sectors.

Limitations of TRACE

• While TRACE is a simple and cost-effective tool, it does not provide detailed cost analysis for certain projects.
• It does not account for institutional and legislative barriers that may affect the feasibility of energy efficiency measures.
• The study is limited to the city center, as collecting data for the entire metropolitan area is complex.

Cross Growth Pole Comparison

• District Heating is a top priority in most growth poles, with Iaşi ranking it as the first priority.
• Street Lighting is a high priority in Iaşi, with significant potential for savings.
• Municipal Buildings and Public Transportation are also key areas for improvement.
• The city has made notable progress in the water and wastewater sector, with extensive investments since the 2000s.

Conclusion

The TRACE study highlights the potential for Iaşi to significantly improve its energy efficiency by focusing on key sectors such as district heating, public transport, and municipal buildings. It also underscores the importance of developing a strategic and actionable plan to guide future improvements. While the tool is effective in identifying priority areas, further in-depth analysis and institutional support will be necessary to implement the recommended measures effectively.
