  2. 1. A Shift in Urban Mobility and Parking? : Exploring Policies in Relation to Practices

    Author : Fredrik Johansson; Greger Henriksson; Jonas Åkerman; Pelle Envall; Greg Marsden; KTH; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Parking; mobility services; flexible parking requirements; sustainable mobility paradigm; Strategier för hållbar utveckling; Strategies for sustainable development;

    Abstract : The transport sector is associated with many environmental challenges, including carbon dioxide (CO2) emissions. Research indicate that CO2 emissions should decrease by at least 50 % per decade in order to be in line with the Paris Agreement, and the transport sector is highlighted as a particularly challenging sector.

  4. 2. Born in fire, borne by air : Source attribution and physicochemical characterization of ship and ambient aerosols in the Baltic region

    Author : Stina Ausmeel; MERGE: ModElling the Regional and Global Earth system; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; anthropogenic air pollution; aerosol; black carbon; plumes; ship emissions; absorption; source apportionment; climate; Fysicumarkivet A:2020:Ausmeel;

    Abstract : Aerosol emissions from anthropogenic activities cause detrimental health effects and affect the climate system. Combustion is a large source of airborne fine particulate matter (PM2.5) and the uncertainties of the climate role of these emissions are still large. READ MORE

  5. 3. Diffusion of innovative domestic heating systems and multi-storey wood-framed buildings in Sweden

    Author : Krushna Mahapatra; Leif Gustavsson; Ole Jess Olsen; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental engineering; Miljöteknik;

    Abstract : The diffusion of innovations that promote sustainable use of forest resources and energy efficiency is important for reducing greenhouse gas emission and dependency on oil. In this thesis the ‘systems of innovation’ (SI)The SI analyses showed that several sources of path dependency, resulting from the establishment and growth of the concrete-based construction system over the past 100 years, hinder the expansion of a wood-based multi-storeyThe adopter-centric approach included household questionnaire surveys: one covering the whole of Sweden in 2004 involving 1500 randomly selected homeowners with any type of heating system, and another in the city of Östersund inThe expansion of district heating networks in the detached home sector, particularly those homes with resistance heaters, is often considered difficult.

  6. 4. Characterization of the Combustion of Light Alcohols in CI Engines : Performance, Combustion Characteristics and Emissions

    Author : Sam Shamun; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Methanol; Ethanol; Oxygenated Fuel Blends; Compression Ignition Engine; Partially Premixed Combustion; Combustion Characteristics; Efficiency; Emissions; Particulate Matter; Metanol; Etanl; Oxygenerade Bränsleblandningar; Kompressionsantänd Motor; Partiellt Förblandad Förbränning; Förbränningsegenskaper; Verkningsgrad; Emissioner; Partiklar;

    Abstract : Alternative fuels for combustion engines are becoming increasingly popular as society is pushing to phase out fossil energy to reduce CO2 emissions. The compression ignition (CI) engine has a high overall efficiency which makes it a valuable option for the transport fleet, despite the well known NOx and soot pollutants it emits. READ MORE

  7. 5. Challenges of renovating the Gothenburg multi-family building stock - An analysis of comprehensive building-specific information, including energy performance, ownership and affordability

    Author : Mikael Mangold; Seppo Junnila; Sweden Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aging building stock; Energy performance certificate; Energy retrofitting; Equity; GIS; Göteborg; Measured energy usage; Multi-family dwellings; Social sustainability; Tenure;

    Abstract : In Sweden and many European countries, the building stock increased at a rapid pace during the period of 1950-1975. This aging building stock is in need of renovation which is a challenge and an opportunity in reaching the energy performance targets as well as decreasing societal inequities. READ MORE
