1. 21. Life Cycle Assessment of Asphalt Pavements including the Feedstock Energy and Asphalt Additives

   Författare :Ali Azhar Butt; Björn Birgisson; John Harvey; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Life Cycle Assessment; feedstock energy; asphalt binder additives; mass-energy flows; bitumen healing; wax; polymer;

   Sammanfattning : Roads are assets to the society and an integral component in the development of a nation’s infrastructure. To build and maintain roads; considerable amounts of materials are required which consume quite an amount of electrical and thermal energy for production, processing and laying. LÄS MER

3. 22. Performance Evaluation and Life Cycle Cost Analysis of the Electrical Generation Unit of a Wave Energy Converter

   Författare :Pinar Tokat; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The main focus of this work is the performance and the economical assessment of a radial flux generator that is used in wave power applications. The wave energy converter (WEC) used in this work is a point absorber, that is considered to move only in heave. LÄS MER

4. 23. RAMS and LCC in rail track maintenance

   Författare :Ambika Prasad Patra; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

   Sammanfattning : Railway infrastructure is a complex system. An important aspect of the rail infrastructure is that the assets have a long useful life. So once installed, it is very difficult to modify the initial design. Thus, the performance of the infrastructure depends on the maintenance and renewal decisions taken during its life cycle.

5. 24. Modelling LCC for Different Indoor Climate Systems

   Författare :Dennis Johansson; Avdelningen för Installations- och klimatiseringslära; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kallt klimat; bostäder; kontor; skolor; samlingslokaler; inomhusklimat; VVS; uppvärmning; ventilation; luftkonditionering; livscykelkostnader; kostnader; optimering; beräkningsmetoder; beräkningsmodeller; teori;

   Sammanfattning : The indoor climate system, which serves a building with a proper indoor air quality and thermal comfort, has been predominantly designed based on the initial investment costs. A life cycle approach could improve both the economic and environmental performance since the energy use would decrease. LÄS MER

7. 25. Energy renovation of multi-family buildings in Sweden : An evaluation of life cycle costs, indoor environment and primary energy use, and a comparison with constructing a new building

   Författare :Lina La Fleur; Bahram Moshfegh; Patrik Rohdin; Andreas Koch; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : Residential buildings account for 27% of the final energy use in the European Union. In cold climates, space heating represents the largest proportion of the energy demand in residential buildings. By implementing energy efficiency measures (EEMs) in existing buildings, energy use can be significantly reduced. LÄS MER
