英国学生平均有30%的清醒时间在学校度过。虽然室内环境质量（IEQ）对他们的健康和成就至关重要，但学校建筑也是英国碳减排战略的关键部分。为了解决能源效率和IEQ之间的冲突，英国教室存量的预测模型应纳入能源和IEQ性能标准，包括能源改造和IEQ改善措施的动态方案。在此基础上，我们开发了一种新的方法，自动生成，模拟，后处理和分析的EnergyPlus英国教室原型模型。这种建模有利于学校建筑性能的多参数评估，同时纳入股票范围的异质性和纵向动态changes.As改造的程度增加，减少增量能源需求减少量化和被动通风在缓解过热的有效性增加被确定。在应用一系列IEQ改善方法后，南向方向对过热的负面影响有所减少。然而，在1945-1967年时代的教室低天花板高度的影响，这些IEQ缓解计算成绩的有效性，需要设计，而不是缓解策略作为补救解决方案。防止NO2污染进入的策略可能比PM2.5更有效，夜间通风可以避免在日常高峰期间进入，并且对位置更敏感。未来的工作应根据利益相关者的偏好将多种标准纳入单一工具，以提高改造决策的质量。
UK schoolchildren spend on average 30% of their waking lives inside schools. While indoor environmental quality (IEQ) is critical for their health and attainment, school buildings are also a key part of the UK's carbon emissions reduction strategy. To address conflicts between energy efficiency and IEQ, predictive models of UK classroom stock should incorporate energy and IEQ performance criteria across dynamic scenarios comprising energy retrofit and IEQ improvement measures. On this basis, we have developed a novel approach for auto-generation, simulation, post-processing and analysis of EnergyPlus UK classroom archetype models. Such modelling facilitates the multi-parameter evaluation of school building performance, whilst incorporating stock-wide heterogeneity and longitudinal dynamic changes.As extent of retrofit increases, decreasing incremental energy demand reduction was quantified and increasing effectiveness of passive ventilation at mitigating overheating was identified. Negative impact of South facing orientation on overheating was reduced after applying a range of IEQ improvement methods. However, low ceiling heights in 1945–1967 era classrooms impact the efficacy of these IEQ mitigations on calculated attainment, requiring design rather than mitigation strategies as a remedial solution. Strategies preventing NO2pollution ingress could be more-effective than PM2.5, with night-time ventilation avoiding ingress during daily peaks and greater sensitivity to location. Future work shall incorporate multiple criteria into a single tool based on stakeholder preferences to improve quality of retrofit decision making.
