1. 16. Life Cycle Impacts of Road Infrastructure : Assessment of energy use and greenhouse gas emissions

   Författare :Sofiia Miliutenko; Anna Björklund; Robert Karlsson; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cumulative Energy Demand CED ; Global Warming Potential GWP ; Life Cycle Assessment LCA ; road infrastructure; strategic planning;

   Sammanfattning : Road infrastructure is essential in the development of human society, but has both negative and positive impacts. Large amounts of money and natural resources are spent each year on its construction, operation and maintenance. Obviously, there is potentially significantenvironmental impact associated with these activities. LÄS MER

3. 17. Towards Sustainable Construction: Life Cycle Assessment of Railway Bridges

   Författare :Guangli Du; Raid Karoumi; Håkan Sundquist; Helge Brattebo; KTH; []
   Nyckelord :Life cycle assessment; LCA; Environment; Railway Bridge; Sustainability; Järnvägsgruppen - Infrastruktur; Järnvägsgruppen - Infrastruktur;

   Sammanfattning : Since last few decades, the increased pressure from the environmental issues of natural resource depletion, global warming and air pollution have posed a great challenge worldwide. Among all the industrial fields, bridge infrastructures and their belonged construction sector contribute to a wide range of energy and raw materials consumptions, which is responsible for the most significant pollutions.

4. 18. Life Cycle Assessment of Present and Future Marine Fuels

   Författare :Selma Bengtsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LCA; marine fuels; environmental impact; LNG; biofuels; heavy fuel oil; Life Cycle Assessment; marine gas oil; liquefied natural gas;

   Sammanfattning : Interest in new fuels for marine propulsion is growing, mainly as a result of stricter environmental regulations but also due to increased attention to air pollution, greenhouse gas emissions and the uncertainty of future oil supply. Several different fuels and exhaust abatement technologies are proposed for marine transportation, all of which have different advantages and disadvantages in relation to the environment and human health.

   Sammanfattning : The construction industry is expected to play a vital role in meeting the global societal challenge of ensuring sustainable development. Due to the increasing importance of the embodied impact of materials, this thesis investigates how the sustainability performance of building materials can be improved. LÄS MER

7. 20. Simplifying LCA use in the life cycle of residential buildings in Sweden

   Författare :Sjouke Beemsterboer; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Life cycle assessment LCA ; Simplified LCA; building construction; multifamily residential building; Life Cycle Management LCM ;

   Sammanfattning : This thesis discusses the use of environmental life cycle assessment (LCA) in the building life cycle. While the life cycle of a residential building is an important source of environmental concern, knowledge about LCA remains scarce and sporadic in most construction companies. LÄS MER
