INNOVATIVE METHODOLOGY BASED IN CIRCULAR ECONOMY AND ARTIFICIAL INTELLIGENCE TO FOSTER THE TRANSITION TO SUSTAINABLE AND VERY HIGH ENERGY PERFORMANCE BUILDINGS AT A COST OPTIMAL LEVEL- (SNUG)

建筑占欧盟能源消耗和二氧化碳排放量的40%以上。因此，行政长官制定了雄心勃勃的建筑标准，目标是在2050年之前将所有现有建筑改造为ZEB，以达到完全脱碳的建筑存量。Snug的目标是在三个具有不同特征、用途和气候的真实建筑上演示应用创新方法来支持新建筑或翻新工程的规划者选择最合适的隔热材料集、它们的组合和位置，以最大限度地提高能源效率并最大限度地减少建筑在其整个生命周期中的温室气体排放，使其ZEB评级更容易达到，考虑到特定的建筑特征和环境，以最佳的成本水平。这一方法将得到以下支持：-基于人工智能和虚拟模拟的数字工具助理，它将根据与能源需求(运行和嵌入能源)、可持续性、安全和安保以及建筑成本和特殊功能相关的基准预测，涵盖隔热材料和布局的几个最终选项。-基于循环经济、智能和/或可再生材料的创新可持续设计隔热材料和轻质预制解决方案已准备好投放市场部署，与目前的市场解决方案相比，能够以具有竞争力的成本提高建筑的能效和可持续性。-绝缘材料数据库，包括技术和LCA信息。创新的隔热解决方案将纳入其中，包括目前市场上的解决方案。该数据库将作为公开数据成果发布。-数字建筑日志，以数字和可与BIM和DTA互操作的格式收集建筑物整个生命周期的所有信息。这一DBL将促进建造业和利益相关者之间的决策和信息共享

Buildings are responsible for over 40% of the energy consumption and CO2 emissions in EU. Accordingly, The CE has stablished ambitious building standard aiming to transform all existing buildings into ZEBs by 2050 to reach a fully decarbonised building stock. SNUG aims to demonstrate on three real buildings with different characteristics, uses and climatology, the application of an innovative methodology to support planners of new buildings or retrofitting works in selecting the most appropriate set of insulation materials, their combination and placement to maximise the energy efficiency and minimize GHG emissions of the building throughout its life cycle to make its ZEB rating more easily achievable, considering specific building characteristics and its environment, at an optimal cost level. This methodology will be supported by: -A Digital Tool Assistant based on AI and virtual simulation which will range several final options of thermal insulation materials and layouts, based on benchmarks predictions related with energy demand (operational and embedded energy), sustainability, safe & security and cost and particular features of buildings. -Innovative sustainable-by-design thermal insulation materials and lightweight prefab solutions ready to the market deployment, based on Circular Economy, Smart and/or Renewable materials, able to improve energy efficiency and sustainability of buildings in comparison with current market solutions at a competitive cost. -Insulation materials database, including technical and LCA information. Innovative thermal insulation solutions will be incorporated including current solutions in the market. This database will be released as an open data outcome. -A Digital Building Logbook, collecting all the information about the buildings throughout their whole life in a digital and interoperable format with BIM and the DTA. This DBL will facilitate decision making and information sharing within the construction sector and stakeholders
