Wood: a major asset for the future of construction
There’s nothing new about timber construction, as wood has been used on a large scale in the Nordic countries for decades. In this country, however, it is slow to establish itself as a real alternative to traditional construction methods, although there are clear signs that it is being used more widely. Faced with the challenges ahead, not least of which is climate change, wood may turn out to be an extremely effective tool both from the environmental and economic perspective, and in terms of the well-being it brings to occupants. Wood Shapers totally understands this and, fortunately, is not alone.
2) Undeniable carbon advantages
According to McKinsey Global Institute, 90% of CO2 emissions in the new construction sector between 2015 and 2050 will come from the production of materials and 10% from their implementation. We also know that the building sector alone accounts for 39% of greenhouse gas emissions, which must be reduced by 50% in the years ahead (European Green Deal).
The future challenge for the sector is therefore to increase the use of bio-based materials, of which wood is obviously a part. According to some studies, every m3 of wood used in construction as a substitute for other construction materials reduces CO2 emissions by 1.1 tonnes. If we add to this the 0.9 tonne stored in the wood (as the tree grows, it absorbs CO2 and stores it in the wood at a rate of 0.9 tonne per m3), we obtain a total reduction of 2 tonnes/m3.
In this regard, a building constructed in Denver, Colorado, (the Platte Fifteen: 14,000 m2 over five storeys) shows that there is a 70% reduction of greenhouse gases in a timber construction compared to the same building in steel.
This figure can even be as high as 76% if we compare it with a concrete construction.

4) A sense of well-being
Biophilia is described as an innate love of nature and a willingness to surround oneself with natural objects and systems. We spend less than 6 to 8% of our time outdoors in contact with nature. This results in a disconnect. Anyone who lives in a building constructed from timber will tell you that wood gives a feeling of well-being; it is a warm, healthy and natural material. A great many different studies demonstrate its beneficial effects on health, and in particular on blood pressure and heart rate. Productivity in a timber-built workplace is found to increase by 8%, and sense of well-being by 13%. In Austria, a study by Dr. Moser (Schule ohne Stress) shows an increase in concentration among pupils in classrooms built from wood.
5) Economies of scale
Building with wood is based on a simple and economical principle: prefabrication and dry assembly of elements in the factory. On site, this results in a time saving of 35% compared to traditional construction. Other advantages are reduced accident risks, lower risk of error on site due to the 3D modelling (the constituent elements are manufactured on digitally controlled machines), less noise and dust pollution, as well the 75% waste reduction.
In a nutshell, wood has everything it needs to succeed and become established as the building material of the future in the years to come. And it is on the right track, as more and more people – ordinary folk as well as professionals – are convinced of its qualities.

Come and find us at our next presentation at the REALTY summit on 21 September, in the heart of the highly symbolic Gare Maritime, where we will be discussing the future of wood construction. Are we ready, and what are the implications for project financing? Is timber construction cheaper to finance than traditional building materials? Find out what our experts think: Aurore de Montjoie (Deputy Head Real Estate Finance Belgium, BNP Paribas Fortis), Jean-Pierre Hanin (CEO Cofinimmo), David Roulin (CEO ArtBuild Architects), Michiel Riedijk (Director Riedijk Neutelings Architecten), Arnaud Regout (CEO WoodShapers).
