21. Life cycle assessment and life cycle cost analysis of a single-family house
Sammanfattning : The building industry is responsible for 35% of final energy use and 38% of CO2 emissions at a global level. The European Union aims to reduce CO2 emissions in the building industry by up to 90% by the year 2050. Therefore, it is important to consider the environmental impacts buildings have. LÄS MER
22. Multi-year maintenance optimisation for paved public roads - segment based modelling and price-directive decomposition
Sammanfattning : I avhandlingen studeras hur kostnadseffektiva underhålls- (uh-)planer för belagd väg kan genereras, på basis av information om aktuellt vägytetillstånd och funktionella modeller för kostnads- och tillståndsförändringar, delvis utvecklade i samarbete med svenska Vägverket (VV). Tilltänkt användning är på strategisk och programnivå, innan mer detaljerad objektinformation finns att tillgå. LÄS MER
23. Sexual conflict and selection on pistil and pollen traits
Sammanfattning : The incidence of sexual selection in plants is today acknowledged, however, just as in animals, evolution and maintenance of mate choice is gravely underexplored. Moreover, the potential for sexual conflicts to occur in plants has only been assessed empirically to a very limited degree. LÄS MER
24. Stainless Steel Corrugated Web Girders for Composite Road Bridges: Concept Evaluation and Flange Buckling Resistance
Sammanfattning : Achieving a sustainable bridge design requires careful consideration of economic viability and environmental impact over the entire lifespan of the structure. While stainless steel is recognized for its excellent life cycle performance, its high cost prevents it from being used to a larger extent in bridges. LÄS MER
25. Green procurement of buildings: estimation of environmental impact and life-cycle cost
Sammanfattning : This thesis focuses on environmental impact reduction and life-cycle cost estimations in building procurement. The aim for the work presented in this thesis is to contribute to the understanding of whether costs and environmental impact of a building can be integrated in a, from the users perspective, practical model applied for tender evaluation.
