With the outbreak of COVID-19, the urgency of wide-scale healthcare infrastructure development has been felt globally for human survival. To accommodate a large infected population, copious wards are to be built within the prevalent constraints of land, power and material availability. This study designs a two-bed modular healthcare ward which is shrunk in size to minimize the requirement of space and other construction commodities such as materials, labour and power. Additionally, HVAC energy usage is accounted for conservation. The health safety and thermal comfort of occupants are regulated by monitoring indoor environment attributes while pushing towards a resource-efficient structure. Two popular envelope thermal retrofits viz. phase change material and thermal insulation are tested to conceive gains in terms of improved energy performance of the ward. Various ward designs contest with their energy performance and occupant's health safety and comfort characteristics in a multicriteria decision making process for delivering the most favourable solution. Subsequently, the most suitable solution is offered by a design involving thermal insulation retrofit with 8 ACH fresh air supply rate and 26°C inlet air temperature. The proposed design can support developing nations to contrive quick response to pandemic outbreaks with reduced construction (cost, time) and energy loads.
随着新冠疫情的爆发，为了人类生存，全球都感受到了大规模医疗基础设施建设的紧迫性。为了容纳大量感染者，需要在土地、电力和材料供应普遍受限的情况下建造大量病房。本研究设计了一种双床模块化医疗病房，缩小其尺寸以尽量减少空间以及材料、劳动力和电力等其他建筑资源的需求。此外，考虑了暖通空调的能源使用以实现节能。通过监测室内环境属性来调节居住者的健康安全和热舒适度，同时朝着资源高效型结构发展。测试了两种常见的围护结构热改造方法，即相变材料和隔热材料，以期在病房能源性能提升方面取得成效。在多标准决策过程中，各种病房设计在能源性能、居住者健康安全和舒适度方面展开竞争，以提供最有利的解决方案。随后，一种涉及隔热改造、8次换气新风供应率和26°C进气温度的设计提供了最合适的解决方案。所提出的设计可以支持发展中国家在减少建设（成本、时间）和能源负荷的情况下，对疫情爆发做出快速反应。
