  1. 16. Product Development of Electronic Devices for Improved Environmental Performance : Finding improvement opportunities using ecodesign tools and success factors

    University essay from Linköpings universitet/Industriell miljöteknik

    Author : Angelica Reyes; Alice Landin; [2022]
    Keywords : Ecodesign; Ecodesign implementation; Building Management Systems; Electronics; Environmental Sustainability; QFDE; LCA;

    Abstract : The energy consumption of the use phase of buildings accounts for almost 30 per-cent of the global energy consumption and is expected to increase in the coming years (Santamouris and Vasilakopoulou, 2021). Furthermore, increasing demand for energy-efficient buildings can be expected due to the introduction of legislative frameworks, such as the Energy Performance of Buildings Directive and the Energy Efficiency Directive (European Commission, 2022b).
