Abstract

Purpose of Review

The main goal of this study was to review the latest developments in the use of wood-based building materials and systems over the last 5 years. The methodology was carried out by using the systematic review procedure. This study considered only peer-reviewed articles written in English published over the last 5 years (2018 to 2022) on materials used in structural systems and building envelopes.

Recent Findings

The energy demand for cooling and heating represents from 40 to 60% of a building’s energy consumption depending on the energy mix. Every increase in energy efficiency increases the pressure on the energy embedded in the materials. In this context, bio-based and especially wood-based materials are gaining popularity. Their use is significant in structural and envelope systems, making them a powerful tool for working on both efficiency and embedded energy. Furthermore, the building construction industry is among the most significant in the economy of industrialized countries.

Summary

Forests are a carbon asset for our societies. Since buildings have been identified as a global warming mitigation tool, an increase in the use of wood and bio-based products should be considered. To support a better scientific understanding of building carbon sequestration under climate changes, a thorough understanding of structural and envelope systems is needed. Various materials are used in these complex systems, and a variety of assembly options are available. In structural systems, research has tended to be incremental over the last 5 years, with a focus on prefabrication and hybrid structures. As new designs and materials are introduced in the future, building physics principles will become increasingly important to ensure the quality of building envelopes. This review presents the latest research related to wood structural and envelope systems to support their use in the construction industry.

木结构建筑:结构和围护系统的趋势和机遇
回顾的目的本研究的主要目的是回顾过去五年来木质建筑材料和系统使用的最新发展。方法采用系统评价程序进行。这项研究只考虑了过去5年(2018年至2022年)发表的关于结构系统和建筑围护结构材料的同行评议的英文文章。根据能源结构的不同,制冷和供暖的能源需求占建筑物能源消耗的40%至60%。能源效率的每一次提高都增加了材料中所含能量的压力。在这种情况下,生物基材料,特别是木基材料越来越受欢迎。它们在结构和围护结构系统中的应用非常重要,使它们成为提高效率和嵌入式能源的有力工具。此外,建筑行业是工业化国家经济中最重要的行业之一。森林是我们社会的碳资产。由于建筑物已被确定为减缓全球变暖的工具,应考虑增加使用木材和生物基产品。为了更好地科学理解气候变化下的建筑碳封存,需要对结构和围护结构系统有一个全面的了解。在这些复杂的系统中使用各种材料,并提供各种组装选项。在结构系统方面,在过去的5年中,研究趋向于增量,重点是预制和混合结构。随着未来新设计和新材料的引入,建筑物理原理对保证建筑围护结构的质量将变得越来越重要。这篇综述介绍了有关木结构和围护结构系统的最新研究,以支持它们在建筑行业中的使用。

期刊介绍: Current Forestry Reports features in-depth review articles written by global experts on significant advancements in forestry. Its goal is to provide clear, insightful, and balanced contributions that highlight and summarize important topics for forestry researchers and managers. To achieve this, the journal appoints international authorities as Section Editors in various key subject areas like physiological processes, tree genetics, forest management, remote sensing, and wood structure and function. These Section Editors select topics for which leading experts contribute comprehensive review articles that focus on new developments and recently published papers of great importance. Moreover, an international Editorial Board evaluates the yearly table of contents, suggests articles of special interest to their specific country or region, and ensures that the topics are up-to-date and include emerging research.
