The existing residential building stock in many industrialized countries is large but extremely energy inefficient, despite the existence of energy directives that apply mostly to new construction. Prefabricated building refurbishment for energy upgrading is a viable option for the existing building stock, but solutions need to adapt to each case and usage in order to respond to specific requirements. The “RECO2ST” project (Horizon 2020) is used as example of a forecast methodology that can help achieve nearly zero energy refurbishments, through selection of innovative modular elements for the opaque and transparent areas of the building envelope, covering diverse energy reduction strategies while improving thermal comfort and indoor air quality. This integrated approach is not usual in the field. The Technical Note studies a series of facade and active window technologies that supply climate strategies such as insulation, heat recovery and ventilation. The methodology is demonstrated for three sample cases using a typical refurbishment scenario. It is evaluated through energy simulation and analysis of improvements in thermal comfort and indoor air quality indicators. Practical application: The methodology helps to reduce guesswork for actions to be taken in order to refurbish and upgrade the existing housing stock to comply with current energy directives. It takes into account at the same time energy performance and user comfort, as expressed through indoor air quality.

通过结合热和舒适性能方法，采用适应性解决方案来实现接近零能耗的建筑

尽管存在主要适用于新建筑的能源指令，但许多工业化国家中的现有住宅建筑存量很大，但能源效率极低。预制建筑翻新以进行能源升级对于现有建筑群来说是一个可行的选择，但是解决方案需要适应每种情况和用途，以响应特定要求。“ RECO2ST”项目（Horizo​​n 2020）被用作预测方法的示例，该方法可通过为建筑围护结构的不透明和透明区域选择创新的模块化元素，帮助实现近乎零的能源翻新，涵盖各种节能策略，同时进行改进热舒适性和室内空气质量。这种集成方法在该领域并不常见。该技术说明研究了一系列幕墙和活动窗户技术，这些技术提供了诸如保温，热回收和通风之类的气候策略。使用典型的翻新方案针对三个示例案例演示了该方法。通过能源模拟以及对热舒适性和室内空气质量指标的改进进行分析来评估它。实际应用：该方法有助于减少为更新和升级现有住房以满足现行能源指令而要采取的措施的猜测。它同时考虑了能源性能和用户舒适度（通过室内空气质量来表示）。使用典型的翻新方案针对三个示例案例演示了该方法。通过能源模拟以及对热舒适性和室内空气质量指标的改进进行分析来评估它。实际应用：该方法有助于减少为更新和升级现有住房以满足现行能源指令而要采取的措施的猜测。它同时考虑了能源性能和用户舒适度（通过室内空气质量来表示）。使用典型的翻新方案针对三个示例案例演示了该方法。通过能源模拟以及对热舒适性和室内空气质量指标的改进进行分析来评估它。实际应用：该方法有助于减少为更新和升级现有住房以满足现行能源指令而要采取的措施的猜测。它同时考虑了能源性能和用户舒适度（通过室内空气质量来表示）。该方法有助于减少为翻新和升级现有住房以满足现行能源指令而要采取的措施的猜测。它同时考虑了能源性能和用户舒适度（通过室内空气质量来表示）。该方法有助于减少为翻新和升级现有住房以满足现行能源指令而要采取的措施的猜测。它同时考虑了能源性能和用户舒适度（通过室内空气质量来表示）。
