1. 1. Perceptions of intensive forestry and multi-storey wood frames among Swedish actors

   Författare :Kerstin Hemström; Krushna Mahapatra; Ole Jess Olsen; Anders Lunnan; Linnéuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multi-storey wood frames; intensive forestry; actor perceptions; legitimacy; path dependence; Byggteknik; Civil engineering;

   Sammanfattning : Implementation of intensive forestry (fertilization, cultivation of non-native tree species, and clone cultivation) on part of the forested land area in Sweden and an increased construction of wood-framed multi-storey buildings can contribute to reduce the net carbon dioxide emissions of the built environment. This thesis evaluates the acceptance of and interest in intensive forestry and multi-storey wood frames among different actors, and some of the underlying reasons for their approach. LÄS MER

3. 2. Life-Cycle Energy and Carbon Implications of Wood-Based Products and Construction

   Författare :Roger Sathre; Leif Gustavsson; Birger Solberg; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; forest products; climate change mitigation; carbon balance; energy; life cycle; wood; land use; Environmental engineering; Miljöteknik;

   Sammanfattning : Forests can be an important element of an overall strategy to limit the atmospheric concentration of carbon dioxide (CO2) that contributes to climate change. As an integral part of the global carbon cycle, forests remove CO2 from the atmosphere as they grow, and accumulate carbon in tree biomass. LÄS MER

4. 3. Framing Technological Development in a Concrete Context : The Use of Wood in the Swedish Construction Industry

   Författare :Anna Bengtson; Håkan Håkansson; Alexandra Waluszewski; Poul Rind Christensen; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Business studies; technological development; context; industrial networks; construction industry; Företagsekonomi; Business studies; Företagsekonomi; nationalekonomi; Economics;

   Sammanfattning : An understanding of the factors that condition technological development is of vital importance for business theory as well as for practitioners. The contextual setting of the development constitutes one area of inquiry into this research field. LÄS MER

5. 4. Life Cycle Assessment of Building Products. Case Studies and Methodology

   Författare :Åsa Jönsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VOCs; environmental assessment; floorings; methods; LCA; concrete; indoor climate; Life Cycle Assessment; structural frames; building materials; steel; tools;

   Sammanfattning : The main objectives of this thesis were to demonstrate how Life Cycle Assessment (LCA) may be applied to building products, to describe what methodological LCA issues are specific to building products, to work out solutions to some of these issues and to relate LCA to other environmental assessment methods that may be applied to building products. First, in a literature study, the state of the art in the field of environmental assessment of building products is described, and the five articles constituting the thesis are put into context.
