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

Core Content

The TRACE (Tool for Rapid Assessment of City Energy) study was conducted in Constanta, Romania, as part of the Romania Regional Development Program, aimed at improving energy efficiency in urban areas. The study focuses on six key sectors: urban transport, municipal buildings, water and wastewater, solid waste management, public lighting, and power and heat. It provides an overview of the city's current energy performance and outlines recommendations for future improvements.

Main Findings

• Energy Efficiency Strategy: Constanta is encouraged to develop an energy efficiency strategy and action plan, including a Sustainable Energy Action Plan (SEAP) to reduce greenhouse gas emissions by 20% by 2020.
• District Heating: Identified as the sector with the highest energy savings potential, the district heating system requires maintenance and upgrading to reduce losses and improve service quality.
• Urban Transport: The city faces significant challenges in reducing traffic congestion and fuel consumption. Non-motorized transport development and parking restraint measures are key recommendations.
• Municipal Buildings: The city has data on energy consumption, but lacks benchmarking and retrofitting programs to maximize savings.
• Street Lighting: A timing program is proposed to optimize energy use, with the potential for quick implementation.
• Public Lighting: The city has already replaced mercury lamps with more efficient sodium vapor bulbs.
• Solid Waste Management: The sector has low recycling rates and lacks dedicated bike lanes, which is a priority for improvement.
• Water Sector: The city has a well-metered water network, and significant investments have been made in infrastructure modernization, resulting in reduced energy consumption.

Key Recommendations

• District Heating Maintenance and Upgrade: Rehabilitation of the hot water and heat pipes to reduce losses and improve service quality.
• Non-Motorized Transport Development: Expansion of pedestrian networks and development of bike lanes to reduce private car usage.
• Parking Restraint Measures: Introduction of "Park and Ride" facilities and increased parking costs to manage traffic.
• Public Transport Development: Modernization of the public transport fleet, introduction of energy-efficient vehicles, and e-ticketing systems.
• Municipal Building Benchmarking Program: Creation of a comprehensive database to track energy consumption and identify buildings with the highest savings potential.
• Municipal Building Audit and Retrofit: Conducting audits and retrofitting to improve the energy performance of public buildings.
• Street Lighting Timing Program: Adjusting lighting schedules based on activity levels and weather conditions to reduce electricity use.
• Energy Efficiency Action Plan and Strategy: Developing a strategic document to guide energy efficiency initiatives and align with the Covenant of Mayors.

Limitations of TRACE

• The tool is simple and quick, but lacks depth in cost analysis and does not account for institutional and legislative constraints.
• It provides prioritization of sectors based on savings potential and local authority control, but may not fully reflect the financial implications of certain projects.

Implementation Timeframe

Institutional and Legislative Context

• The power and heat sector is managed nationally, with tariffs regulated by the government.
• Energy liberalization is underway, with subsidies expected to be phased out by 2017.
• Renewable energy is encouraged, with Green Certificates available to producers, although some are postponed until 2017.

Conclusion

The TRACE study highlights the potential for significant energy savings in Constanta, particularly in the district heating and urban transport sectors. It emphasizes the importance of benchmarking, audit, and retrofitting municipal buildings, as well as the development of non-motorized transport and public lighting efficiency measures. The study also recommends the development of an energy efficiency strategy and action plan to guide future initiatives and align with EU sustainability goals. While the city has made some positive strides in energy efficiency, further efforts are needed to reduce energy consumption, lower heating costs, and improve the quality of life for residents.
