  2. 21. Environmental Assessment of Buildings and the influence on architectural design

    Author : Marita Wallhagen; Göran Finnveden; Mauritz Glaumann; Tove Malmqvist; Ole Jörgen Hanssen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; green building; sustainable building; environmental assessment; assessment tool; architectural design; CO2 Carbondioxide ; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

    Abstract : This licentiate thesis examines environmental assessment tools for buildings. This is done by investigating, analysing, comparing and testing how different environmental assessment tools measure the environmental performance of buildings and examining the consequences this may have on architectural design.

  4. 22. Life cycle assessment of electric vehicle batteries and new technologies

    Author : Mats Zackrisson; Magnus Wiktorsson; Martin Kurdve; Christina Jönsson; Anders Nordelöf; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; life cycle assessment; LCA; electric vehicle; sustainability; eco-design; Production Engineering; Industriell produktion;

    Abstract : Electrification of vehicles has for decades been explored as a possible solution to the problem of climate change. Today, in 2021, the issue is no longer whether the electrification of vehicle fleets ought to happen but rather how it can be achieved with as little environmental impact as possible. READ MORE
