Optimized energy use and water provision in school buildings play an important role in the sustainability performance of municipalities, and are included in the local sustainable energy policies. Hot climate conditions exacerbate the need for the use of cooling devices and are usually associated to water scarcity problems. Additionally, school buildings in these areas are usually lacking good thermal insulation conditions and energy efficiency measures. This work analyses the energy, material and water requirement activities of two schools located in a hot climate area, and evaluates the aggregated energy and water consumption, the water scarcity exacerbation problems, and the associated carbon footprint through Life Cycle Assessment, which allows the quantification of the impacts along the whole value chain of the school activities per student. Additionally, the effects of different improvement measures, such as the implementation of renewable energy sources and the optimization of energy use based on energy efficiency measures, such as changes in the lighting technologies, are quantified. The results show that schools could reduce the fossil energy demand of the building in the operating and maintenance phase per student between 4.89% and 6.03% by means of the implementation of non-renewable heating measures, between 64.06% and 78.98% by means of the implementation of renewable heating solutions, and between 12.05% and 9.54% by means of the implementation of lighting substitution measures.

优化学校建筑中的能源使用和水供应在市政的可持续发展绩效中发挥着重要作用，并被纳入当地的可持续能源政策中。炎热的气候条件加剧了对使用冷却装置的需求，并且通常与缺水问题相关。此外，这些地区的教学楼通常缺乏良好的隔热条件和节能措施。这项工作分析了位于炎热气候地区的两所学校的能源，物质和水需求活动，并通过生命周期评估评估了能源和水的总消耗，缺水加剧的问题以及相关的碳足迹，从而可以量化每个学生在学校活动的整个价值链中的影响。此外，量化了不同改进措施（例如实施可再生能源和基于能效措施（例如照明技术的变化）的能源使用优化）的影响。结果表明，通过实施不可再生的供热措施，学校可以在运营和维护阶段将每名学生的建筑物的化石能源需求降低4.89％至6.03％，通过实施可再生能源措施将其降低64.06％至78.98％。实施可再生供暖解决方案，并通过实施照明替代措施实现12.05％至9.54％的比例。例如照明技术的变化。结果表明，通过实施不可再生的供热措施，学校可以在运营和维护阶段将每名学生的建筑物的化石能源需求降低4.89％至6.03％，通过实施可再生能源措施将其降低64.06％至78.98％。实施可再生供暖解决方案，并通过实施照明替代措施实现12.05％至9.54％的比例。例如照明技术的变化。结果表明，通过实施不可再生的供热措施，学校可以在运营和维护阶段将每名学生的建筑物的化石能源需求降低4.89％至6.03％，通过实施可再生能源措施将其降低64.06％至78.98％。实施可再生供暖解决方案，并通过实施照明替代措施实现12.05％至9.54％的比例。
