Summary of the TRACE City Energy Efficiency Diagnostic Study for Braşov, Romania

Core Content

This report presents the findings of the TRACE (Tool for Rapid Assessment of City Energy) diagnostic study conducted in Braşov, Romania, as part of the Romania Regional Development Program. The study evaluates energy efficiency potential across six key sectors and offers recommendations for improving the city's energy performance and quality of life for residents.

Main Sectors and Key Findings

• District Heating:

  • The system has experienced significant customer loss, with only 12,000 apartments currently connected.
  • The system is outdated, leading to high losses in transmission and distribution.
  • The third lowest heating prices in the country have made it less attractive to residents.
  • Potential savings are significant, but the cost of rehabilitation is high.

• Public Transport:

  • The sector is underdeveloped and faces challenges such as outdated buses, lack of dedicated lanes, and inefficient operations.
  • The city is planning to modernize its bus fleet, expand terminals, and introduce e-ticketing and GPS systems.
  • There is a need to improve the attractiveness and efficiency of public transport to reduce private vehicle usage.

• Private Vehicles:

  • The increasing number of private cars has led to traffic congestion and higher fuel consumption.
  • Recommendations focus on promoting non-motorized transport and implementing parking restraint measures.

• Municipal Buildings:

  • Energy efficiency in public buildings, especially healthcare and education, is a priority.
  • A full audit and retrofitting plan is recommended to identify and implement energy-saving measures.

• Street Lighting:

  • The city has already replaced mercury lamps with sodium vapor ones and is implementing an intelligent lighting system.
  • A lighting-timing program is suggested to further optimize energy use and reduce waste.

• Water and Wastewater:

  • High non-revenue water levels and leaks in the network are major issues.
  • A leakage detection and pressure management program is recommended to improve efficiency and reduce environmental impact.

• Solid Waste Management:

  • While selective collection is in place, the rate of recycling remains low.
  • There is potential for improving waste management through better practices and technologies.

Key Recommendations

• District Heating:

  • Continue rehabilitation and upgrading of the network, including modernization of boilers and pipelines.
  • Implement measures to reduce transmission and distribution losses and regain lost market share.

• Non-Motorized Transport:

  • Expand pedestrian areas and bike path networks.
  • Encourage bike rental programs and provide microcredits for low-income citizens to purchase bicycles.

• Public Transport Development:

  • Modernize the public transport fleet and introduce e-ticketing and GPS systems.
  • Develop dedicated bus lanes and improve traffic management to increase efficiency and attractiveness.

• Parking Restraint Measures:

  • Implement "Park and Ride" facilities to promote multimodal transport.
  • Increase parking costs in the city center and ensure new developments include parking allowances.

• Municipal Buildings Audit and Retrofit:

  • Conduct a full audit of municipal buildings to identify energy-saving opportunities.
  • Allocate funds for upgrades and renovations, especially in educational and healthcare facilities.

• Street Lighting Timing Program:

  • Introduce a smart lighting system with sensors to adjust light levels based on weather, activity, and time of day.
  • Connect the system to a SCADA monitoring system for real-time maintenance and damage detection.

• Water and Wastewater Management:

  • Launch a leakage detection and pressure management program to reduce water loss and improve sustainability.
  • Collaborate with non-profit organizations to enhance the effectiveness of infrastructure improvements.

Priority Sectors and Potential Savings

Context and Background

• Braşov is part of the growth corridor between București and Ploiesti, contributing to its relatively high economic performance.
• The city has seen a decline in population due to demographic changes, but its economy remains strong in construction and services.
• The TRACE tool was used to identify the most impactful energy efficiency interventions based on cost and savings potential.

Additional Notes

• The study was conducted in February 2013, with collaboration from local authorities and utility providers.
• The TRACE methodology is a simple, low-cost, and user-friendly tool that enables quick assessment of energy performance across six sectors.
• The report highlights the importance of urban planning in achieving energy efficiency, as dense cities tend to be more efficient in public service delivery.
• Braşov has already implemented several initiatives, such as an intelligent lighting system and the replacement of old lamps, showing progress in energy efficiency.

Conclusion

The TRACE study identifies key areas where Braşov can improve its energy efficiency and reduce environmental impact. While the city has made some progress, there is a need for continued investment in infrastructure, public transport, and building retrofits. The recommendations aim to guide local authorities in making informed decisions that align with national and EU energy efficiency goals.
