  1. 1. Regulating energy performance of residential buildings in cold climate : a study of indicators, criteria, and evaluation methods

    Författare :Ingrid Allard Stolterman; Thomas Olofsson; Gireesh Nair; Folke Björk; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy performance; building simulation; cold climate; energy use; indicators; evaluation methods; building regulations; residential buildings; energy measurements; performance gap; energy signature; sustainable development; hållbar utveckling; fysik; Physics;

    Sammanfattning : Building energy performance has been important in Fennoscandia ever since the early vernacular houses, to combat the cold climate. Due to EU directive 2010/31/EU on the energy performance of buildings (EPBD recast), building energy performance has become even more relevant in northern Europe the last decade. LÄS MER

  3. 2. Applications of artificial neural networks for time series data analysis in energy domain

    Författare :Fan Zhang; Hasan Fleyeh; Stawomir Nowaczyk; Högskolan Dalarna; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Deregulated energy market; electricity prices; district heating; energy efficiency; neural networks; Complex Systems – Microdata Analysis; Komplexa system - mikrodataanalys;

    Sammanfattning : With the development of artificial intelligence techniques and increased installation of smart meters in recent years, time series analysis using historical data in the energy domain becomes applicable. In this thesis, microdata analysis approaches are used, which consist of data acquisition, data processing, data analysis and data modelling, aiming to address two research problems in the energy domain.

    Författare :Martin Eriksson; Bahram Moshfegh; Shahnaz Amiri; Jan Akander; Sasan Sadrizadeh; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy signature; multifamily building; district heating; energy renovation; simulation; heat loss coefficient; balance temperature; base load; energisignatur; flerbostadshus; fjärrvärme; energirenovering; simulering; värmeförlustkoefficient; balanstemperatur; baslast; Hållbar stadsutveckling; Sustainable Urban Development;

    Sammanfattning : Several climate and energy goals have been set in the European Union, one of them being to increase energy efficiency. In Sweden, a large potential for increased energy efficiency lies in the residential and service sectors, which account for about 40% of total energy use. LÄS MER

  5. 4. Improved building energy simulations and verifications by regression

    Författare :Jimmy Vesterberg; Thomas Olofsson; Folke Björk; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Calibrated simulations; Energy signature; Regression; BES; IDA ICE; Multifamily buildings; EUI;

    Sammanfattning : It is common with significant differences between calculated and actual energy use in the building sector. These calculations are often performed with whole building energy simulation (BES) programs. In this process the analyst must make several assumptions about the studied building and its users.
