  2. 6. Life Cycle Impacts of Road Infrastructure : Assessment of energy use and greenhouse gas emissions

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

    Abstract : 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. READ MORE

  4. 7. New refrigerants for vapour compression refrigeration and heat pump systems : evaluation in a context of the requirements set by the F-gas Regulation and the Paris Agreement goals

    Author : Pavel Makhnatch; Rahmatollah Khodabandeh; Angelo Maiorino; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; refrigerant; retrofit; drop-in; HFC; HFO; F-gas Regulation; Kigali Amendment; Montreal protocol; Life cycle climate performance; LCCP; climate change; Energiteknik; Energy Technology;

    Abstract : Given the global commitment to reduce the impact of fluorinated gases on climate and the regulations controlling their use in the European Union (EU), this thesis investigates new refrigerants that have been recently proposed to meet the demands of the refrigeration industry in the EU, which must satisfy the legislative requirements of the F-gas Regulation and facilitate meeting the goals of the Paris Agreement.The legislative requirements of the EU have intensified refrigerant development with reduced GWP.

  5. 8. Microalgal solutions in Nordic conditions : industries transition toward resource recovery?

    Author : Lina Mattsson; Catherine Legrand; Elin Lindehoff; Hanna Farnelid; Kristian Spilling; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Microalgae; algal cultivation; polyculture; resource recovery; seasonal variation; industrial partnership; CO2 mitigation; nitrogen removal; community composition; Ecology; Ekologi; Environmental Biotechnology; Miljöbioteknik; Miljövetenskap; Environmental Science; Akvatisk ekologi; Aquatic Ecology; Mikrobiologi; Microbiology;

    Abstract : Microalgal solutions can through photosynthesis recover greenhouse gas (CO2) and nutrients from industrial waste, reducing climate footprint and eutrophication. An added value to the process is algal biomass containing lipids, proteins, and carbohydrates with commercial potential for biofuel, feed, and fertilizer. READ MORE

  6. 9. Managing high environmental performance? : Applying life cycle approaches and environmental certification tools in the building and real estate sectors

    Author : Nils W. O. Brown; Tove Malmqvist; Peter Guthrie; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; Buildings; operational energy use; life cycle assessment; environmental certification; environmental assessment; renovation; strategy; design process; value creation; embodied environmental impacts; Planering och beslutsanalys; Planning and Decision Analysis;

    Abstract : The main aim of this thesis is  to demonstrate and critically assess life cycle approaches’ and environmental certification (EC) tools’ potential for supporting decisions for improved environmental performance in the building and real estate sectors.Using life cycle approaches, the thesis shows that for new build and renovation cases aiming for low operational energy use that embodied global warming potential (GWP) due to material production can constitute a large portion of a building’s lifetime GWP.

  7. 10. Life cycle assessment and life cycle cost analysis of a single-family house

    Author : Bojana Petrovic; Ola Eriksson; Marita Wallhagen; Xingxing Zhang; Åsa Wahlström; Högskolan i Gävle; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building; carbon-dioxide equivalent emissions; global warming potential; primary energy use; life cycle assessment; life cycle cost; Byggnad; koldioxidekvivalenta utsläpp; global uppvärmningspotential; pri-märenergianvändning; livscykelbedömning; livscykelkostnad; Hållbar stadsutveckling; Sustainable Urban Development;

    Abstract : 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. READ MORE
