ABSTRACT

Contemporary spaces for surgery are highly energy intensive, much of which is attributed to powerful air conditioning systems intended to force air down onto the patient, surgical staff and instruments to keep airborne pathogens from sedimenting on patients and equipment during surgery. The carbon footprint from these systems is prodigious in a service required to dramatically cut emissions. Sufficient doubts have arisen from experimental modelling and data collected in surgical theatres that pathogens are expelled efficiently to encourage broader speculation about the fundamental configuration of spaces for surgery. One prospective avenue is the investigation of the aseptic movement’s operating room designs of the late nineteenth and early twentieth centuries before the adoption of air conditioning. Historical review and testing of theatre design, as part of the Excising Infections in Surgical Environments (ExISE) project, identified a carefully designed and innovative operating room in Hamburg’s general hospital. The St. Georg’s Operationshaus (1899) is reconstructed digitally, analysed theoretically and modelled experimentally to determine modern utility as a green theatre. Results are promising but are affected by the parallel intent to introduce prodigious natural daylighting; however, the effects of this on the airflow patterns in the space could be managed by modern materials and control technologies.

摘要

现代手术空间是高度能源密集型的，其中大部分归因于强大的空调系统，旨在将空气压向患者、手术人员和器械，以防止空气传播的病原体在手术过程中沉积在患者和设备上。这些系统的碳足迹在显着减少排放所需的服务中是惊人的。手术室中收集的实验模型和数据引起了足够的怀疑，即病原体被有效排出以鼓励对手术空间的基本配置进行更广泛的猜测。一个有前景的途径是在采用空调之前对 19 世纪末和 20 世纪初无菌运动的手术室设计进行调查。剧院设计的历史回顾和测试，作为切除手术环境感染 (ExISE) 项目的一部分，在汉堡的综合医院确定了一个精心设计和创新的手术室。St. Georg's Operationshaus (1899) 以数字方式重建、理论分析和实验建模，以确定作为绿色剧院的现代效用。结果是有希望的，但受到引入大量自然采光的平行意图的影响；然而，这对空间气流模式的影响可以通过现代材料和控制技术来管理。理论分析和实验建模，以确定作为绿色剧院的现代效用。结果是有希望的，但受到引入大量自然采光的平行意图的影响；然而，这对空间气流模式的影响可以通过现代材料和控制技术来管理。理论分析和实验建模，以确定作为绿色剧院的现代效用。结果是有希望的，但受到引入大量自然采光的平行意图的影响；然而，这对空间气流模式的影响可以通过现代材料和控制技术来管理。
