  4. 33. Investigation of the energy saving potential for an office building complex : A study on the viability of an on-site combined heat- and power supply system

    University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Author : Douglas Eriksson; [2018]
    Keywords : geothermal energy system; PV-system; battery; district heating; TRNSYS;

    Abstract : The building stock in the European Union accounts for over 40% of final energy use, where the usage of non-residential buildings may be up to 40% higher than the residential sector. Improving building energy efficiency across all categories of buildings is one key goal of the European energy policies, made prominent by the Climate and Energy package, Energy Performance of Building Directive (EPBD) and Energy Efficiency Directive (EED).
