- Abstract
- It is necessary for all industries to work actively to minimize their impact on the climate, including the construction industry, which accounts for a significant part of Sweden's total CO_2-emissions. Development to produce concrete and steel with more environmentally friendly processes is ongoing, but to lower emissions immediately and achieve long-term sustainability, we need to develop methods for using the renewable resources that are already available. Glued wood elements that make up beams, pillars and slabs are alternatives to load-bearing structures that can replace steel and concrete. But using wood as load bearing structure has its limitations, shorter span of slabs and bulkier structures can lead to poorly utilized floor plans.... (More)

But using wood as load bearing structure has its limitations, shorter span of slabs and bulkier structures can lead to poorly utilized floor plans. In areas where regulations limit the height and exterior dimensions of the building, the number of floors and utilization of the building's area can be a problem for the project's finances and feasibility. To enable the use of wood in multiple types of projects, solutions must be found where each material can be used in its best way. By building hybrid structures where wood is used in combination with other conscious material choices, it is possible to lower the climate footprint while the lettable area becomes higher than for a wood-only structure. Wood and concrete composite slabs are an example of a solution that gives the slab a greater span, enabling a solution with a more efficient floor plan. Several projects with hybrid structures have been built and this report, exploring the possibilities of building a special housing for the elderly a within regulated area, shows that there is great potential to build climate-smart buildings with hybrid solutions.

- Popular Abstract (Swedish)
- Att bygga stommar med enbart trä beskrivs gärna som en lågt hängande frukt i strävan mot att bygga mer miljövänliga hus, men sådana konstruktioner tar i anspråk större utrymme än andra lösningar. Då areapriset för bostäder är högt inom storstäder uppstår ibland situationer där en träkonstruktion inte blir lönsam eller helt enkelt inte får plats, det visar sig då att en träbaserad hybridkonstruktion kan vara en minst lika bra lösning för att sänka byggnadens klimatpåverkan.
