Energy Efficiency Initiative in San Martino Buon Albergo (Verona): A Case Study in Public Building Upgrades
Background: in 2014, the San Martino Buon Albergo Town Council (a large council under Verona) implemented a comprehensive energy efficiency initiative aimed at improving the working environments, infrastructure, and heating costs of 18 public buildings in the town. These buildings included administrative offices, schools, libraries, and sports centres.
Challenges Before the Initiative: Several energy efficiency issues were identified before the project:
- Temperature Variability: Many buildings experienced inconsistent temperatures, being too hot or too cold, indicating poor temperature regulation.
- High Energy Consumption: Despite insufficient comfort levels, energy consumption was high, pointing to inefficient heating systems.
- Difficult Heating Management: Managing and calibrating the heating systems in response to external weather conditions was a challenge.
The Initiative: The primary goal was to reduce heating costs and improve comfort and temperature regulation in these public spaces. From October 2014 to March 2015, all 18 buildings had their heating systems replaced with Warmset underfloor heating mats over a 40-day period.
Post-Installation Monitoring: After installation, the new systems were closely monitored, and thermoregulation strategies were applied to ensure efficiency and comfort.
Benefits of the Intervention: The anticipated benefits mirrored those observed in the pre-school centres where Warmset was first implemented:
- For Users: Enhanced comfort in the working environment.
- For Staff: A more homogeneous temperature, improving overall well-being.
- For Management: Automatic management, making temperature regulation simpler and more effective.
- Financial Benefits: Significant savings in energy consumption.
Significant Cost Savings: A comparison of heating expenses before and after the installation showed substantial cost savings:
- Heating expenditure in 2012/2013: €327,564.
- Heating expenditure in 2014/2015: €144,135. This resulted in an average saving of 56% across the 18 public buildings.
- Notable Savings:
- Some buildings achieved savings exceeding 60%, such as Comune Uffici Tecnici and Scuola Elementare Todaro.
Conclusion: The energy efficiency initiative in San Martino Buon Albergo was a resounding success. The switch to Warmset underfloor heating mats, combined with advanced temperature regulation systems, resulted in substantial cost reductions, improved comfort, and easier system management. The average savings of 56% in heating costs across the public buildings’ portfolio demonstrate the initiative’s success and underline the effectiveness of investing in energy-efficient technologies.
