由于自然灾害和气候变化，现有的砖石和钢筋混凝土建筑遗产普遍老化，不足以满足当今时代的抗震和能源需求。创新技术值得人们对改善建筑性能产生浓厚兴趣，特别是如果包括多任务方法。最好使用环保和生态可持续的材料和系统。因此，由于木材固有的物理和机械性能，其中包括轻质、高强度重量比和自然可持续性，以及易于生产和实现沿着有利的能量性能，木材基元件代表了最佳选择。由于这些特权，近年来，木材已成为建筑行业的全球趋势。基于木材的新技术在修复既有建筑中的应用日益受到重视，在此基础上，本文对木基构件在既有建筑改造中的主要研究和应用进行了综述。两个宏观类别的干预措施，如全球和地方的，被定义为：第一个包括额外的木材外骨骼和内骨骼，而第二个关注的是加强单一的结构元素。强调了在地震和能量综合设计背景下的干预措施的特殊性。
The existing masonry and reinforced concrete built heritage is generally aged and inadequate to the seismic and energetic requirements due to natural hazards and climate change, characterizing present times. Innovative techniques deserve strong interest for improving the building perfomances, especially if including multi-task approaches. Eco-friendly and eco-sustainable materials and systems are preferred. Therefore, timber-based elements represent an optimal option, thanks to the intrinsic physical and mechanical properties of wood, among them lightness, high strength-to-weight ratios and natural sustainability, as well as easiness of production and realization along with favorable energetic performances. For these prerogatives, in recent years, timber has become a trend worldwide in the construction sector. New techniques based on the use of timber are gaining popularity for restoring existing structures belonging to historical, artistic and also productive built heritage.In this framework, the paper presents an overview on the main researches and applications concerning timber-based elements for the retrofit of existing buildings. Two macro-categories of interventions, such as global and local ones, are defined: the first includes additional timber exo- and endo-skeletons, while the second concerns the strengthening of single structural elements. The peculiarities of the interventions in the context of seismic and energetic integrated design are emphasized.
