Constructing with wood : What are the economical and environmental benefits and barriers of using wood as a construction material
One of the biggest issues of our time is the environment. In December 2015, 195 countries agreed to the first-ever universal, legally binding global climate deal, The Paris Protocol – A blueprint for tackling global climate change beyond 2020. The majority of politicians in most countries discuss transportation, industrial plants and factories as the big problem and focuses on this to reduce their impact on the climate. Unfortunately, they are forgetting one big factor, the housing, more specifically the construction of multi-family homes, which have a huge environmental impact. Concrete and steel, which are used in most constructions today, contribute to a huge extent to the emissions of the planet. The purpose of this study is to increase the knowledge of constructing with wood by focusing on the environmental and economical benefits and barriers. One way to reduce the impact that the construction of multi-family homes has on the environment, is to use other materials apart from concrete and steel, such as wood. There are several ways of constructing with wood and some examples are CLT, LVL and GLULAM. Where CLT stands for Cross laminated timber, LVL Laminated veneer lumber and Glulam stands for glue laminated timber. There is evidence that show that wood has a much lower environmental impact than both concrete and steel and this can be traced back to the manufacturing of the wood elements. LCA analyses that have been conducted differ depending on how long life-time they have been calculated for. For a LCA with 50-year life-cycle the wood performed 28 % better (Tove malmqvist, 2016), however when SP/Rise published one where they used 100 years there were no differences that could be determined (SP/Rise,2017). However, it should be noted that both reports state that a LCA comparison between wood and concrete houses are very difficult to make due to the different properties that the materials have, and therefore the reliability of the comparison is not that high. One common notion is that wood catches fire more ...
