The carbon footprint reveals the emission profile of a healthcare building and, when quantified properly, is useful for the design of effective mitigation plans. This article aims to determine the global warming potential associated with the healthcare centre building process in Spain at a 100-year perspective. To this end, six healthcare centres built between 2007 and 2010 were analysed, and the emissions associated with the manufacturing, transport and placement of materials on site – including the final tests and commissioning of the building – were calculated. The results show that the average CO2 equivalent emission per m2 built is 1122.30 kg (standard deviation = 136.46), 1.24 kg (standard deviation = 0.19) per euro spent and 71.35 kg (standard deviation = 7.13) per hour spent on construction. Emissions per user, worker, electrical power and energy consumed were also classified. The material manufacturing and installation stages generate the most emissions, and healthcare centres larger than 2000 m2 appear to emit less CO2 equivalent per m2 when being built than smaller centres. The construction elements that caused most greenhouse gas emissions were also identified. These parameters allow extracting and designing proposals for improvements in environmental management.

评估与医疗中心建设过程相关的全球变暖潜势

碳足迹揭示了医疗保健建筑的排放情况，如果量化得当，可用于设计有效的缓解计划。本文旨在从 100 年的角度确定与西班牙医疗中心建设过程相关的全球变暖潜力。为此，对 2007 年至 2010 年间建造的六个医疗中心进行了分析，并计算了与现场材料制造、运输和放置（包括建筑物的最终测试和调试）相关的排放量。结果表明，每平方米建筑的平均 CO2 当量排放为 1122.30 千克（标准偏差 = 136.46）、每欧元花费 1.24 千克（标准偏差 = 0.19）和 71.35 千克（标准偏差 = 7.13）用于建筑每小时。每个用户、工人的排放量，消耗的电力和能源也进行了分类。材料制造和安装阶段产生的排放量最大，大于 2000 平方米的医疗保健中心在建造时每平方米排放的二氧化碳当量似乎低于较小的中心。还确定了导致大部分温室气体排放的建筑元素。这些参数允许提取和设计改进环境管理的建议。
