Hospitals are controlled yet complex ecosystems which provide a therapeutic environment that promotes healing, wellbeing and work efficiency for patients and staff. As these buildings accommodate the sick and vulnerable, occupant wellbeing and good indoor environmental quality (IEQ) that deals with indoor air quality (IAQ), thermal comfort, lighting and acoustics are important objectives. As the specialist nature of hospital function demands highly controlled indoor environments, this makes them energy intensive buildings due to the complex and varying specifications for their functions and operations. This paper reports on a holistic building performance evaluation covering aspects of indoor air quality, thermal comfort, lighting, acoustics, and energy use. It assesses the performance issues and inter-relationships between IEQ and energy in a new building on a hospital campus in the city of Bristol, United Kingdom. The empirical evidence collated from this case study and the feedback received from the hospital staff help identify the endemic issues and constraints related to hospital buildings, such as the need for robust ventilation strategies in hospitals in urban areas that mitigate the effect of indoor and outdoor air pollution and ensuring the use of planned new low-carbon technologies. Whilst the existing guidelines for building design provide useful instructions for the protection of hospital buildings against ingress of particulate matter from outdoors, more advanced filtration strategies may be required to enact chemical reactions required to control the concentration levels of pollutants such as nitrogen dioxide and benzene. Further lessons for improved performance in operation and maintenance of hospitals are highlighted. These include ensuring that the increasingly available metering and monitoring data in new buildings, through building management systems, is used for efficient and optimal building operations for better IEQ and energy management. Overall, the study highlights the need for an integrated and holistic approach to building performance to ensure that healthy environments are provided while energy efficiency targets are met.

英国新医院大楼的建筑物性能评估:平衡室内环境质量和能源性能

医院是受控但复杂的生态系统,可为患者和医务人员提供促进康复,福祉和工作效率的治疗环境。由于这些建筑物可容纳患者和弱势群体,居住者的福祉和良好的室内环境质量(IEQ),以应对室内空气质量(IAQ),因此热舒适性,照明和声学是重要目标。由于医院职能的专业性质要求对室内环境进行高度控制,因此,由于其功能和操作的规格复杂且变化多端,因此使其成为能源密集型建筑物。本文报告了一项全面的建筑性能评估,涵盖室内空气质量,热舒适性,照明,声学和能源使用等方面。它评估了英国布里斯托尔市一所医院校园中一座新建筑中的性能问题以及IEQ与能源之间的相互关系。从本案例研究中收集的经验证据以及从医院工作人员那里得到的反馈信息有助于确定与医院建筑物有关的地方性问题和制约因素,例如城市地区医院需要采取强有力的通风策略以减轻室内和室外空气的影响污染和确保使用计划中的新低碳技术。现有的建筑物设计指南为保护医院建筑物免受室外颗粒物侵入提供了有用的指导,可能需要更高级的过滤策略来进行化学反应,以控制污染物(如二氧化氮和苯)的浓度水平。重点介绍了进一步的经验教训,以提高医院的运营和维护绩效。这些措施包括通过建筑物管理系统确保新建筑物中越来越多的可用计量和监视数据用于高效和最佳的建筑物运营,以实现更好的IEQ和能源管理。总体而言,该研究强调需要一种综合,整体的建筑性能方法,以确保在达到能效目标的同时提供健康的环境。这些措施包括通过建筑物管理系统确保新建筑物中越来越多的可用计量和监视数据用于高效和最佳的建筑物运营,以实现更好的IEQ和能源管理。总体而言,该研究强调需要一种综合,整体的建筑性能方法,以确保在达到能效目标的同时提供健康的环境。这些措施包括通过建筑物管理系统确保新建筑物中越来越多的可用计量和监视数据用于高效和最佳的建筑物运营,以实现更好的IEQ和能源管理。总体而言,该研究强调需要一种综合,整体的建筑性能方法,以确保在达到能效目标的同时提供健康的环境。
