The European Union 2050 climate neutrality goal and the climate crisis require coordinated efforts to reduce energy consumption in all sectors, and mainly in buildings greatly affected by the increasing temperature, with relevant CO emissions due to inefficient end-use technologies. Moreover, the old building stock of most countries requires suited policies to support renovation programs aimed at improving energy performances and optimize energy uses. A toolbox was developed in the framework of the PrioritEE project to provide policy makers and technicians with a wide set of tools to support energy efficiency in Municipal Public Buildings. The toolbox, available for free, was tested in the partners' communities, proving its effectiveness. The paper illustrates its application to the Potenza Municipality case study in which the online calculator DSTool (the core instrument of the toolbox) was utilized to select and prioritize the energy efficiency interventions in public buildings implementable in a three-year action plan in terms of costs, energy savings, CO emissions' reduction and return on investments. The results highlight that improvements in the building envelopes (walls and roofs), heating and lighting and photovoltaic systems allow reducing CO emission approximately 644 t/year and saving about 2050 MWh/year with a total three-year investment of 1,728,823 EUR.
欧盟 2050 年气候中和目标和气候危机要求协调努力，以减少所有部门的能源消耗，主要是在建筑物中，这些建筑物受到温度升高的极大影响，并且由于低效的终端使用技术而产生相关的 CO 排放。此外，大多数国家的旧建筑存量需要配套政策来支持旨在提高能源性能和优化能源使用的改造计划。在 PrioritEE 项目的框架内开发了一个工具包，为政策制定者和技术人员提供了广泛的工具，以支持市政公共建筑的能源效率。该工具包免费提供，并在合作伙伴的社区中进行了测试，证明了其有效性。本文说明了其在波坦扎市案例研究中的应用，其中使用了在线计算器 DSTool（工具包的核心工具）来选择和优先考虑可在三年行动计划中实施的公共建筑的能源效率干预措施，这些措施在成本、节能、CO 减排和投资回报方面具有可操作性。结果表明，改善建筑围护结构（墙壁和屋顶）、供暖和照明以及光伏系统可以减少约 644 吨/年的 CO 排放，并节省约 2050 兆瓦时/年，总投资为 1728823 欧元，为期三年。
