  1. 1. Life cycle assessment of a plus-energy house

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Tim Lohse; [2020]
    Keywords : ;

    Abstract : Purpose: This study analyses the environmental impacts of a plus-energy house. Such buildings produce more energy in their use-phase than they consume, by generating energy with photovoltaic cells and saving energy via extensive insulation. The entire life cycle of the building is investigated form cradle to grave. READ MORE
