  1. 16. Modelling energy demand in the buildings sector within the EU

    Författare :Eoin Ó Broin; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Residential; EU; Efficiency; Econometrics; Decomposition; Heating; Scenarios;

    Sammanfattning : In the on-going effort within the EU to tackle greenhouse gas emissions and secure future energy supplies, the buildings sector is often referred to as offering a large potential for energy savings. The aim of this thesis is to produce scenarios that highlight the parameters that affect the energy demands and thus potentials for savings of the building sector. LÄS MER

  3. 17. Improving the greenhouse gas balances of bioenergy systems: The cases of Brazilian ethanol production and combined biofuel/district heat production in Europe

    Författare :Andrea Egeskog; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sugarcane ethanol; biofuels for transport; bioenergy; EU; district heating; Brazil;

    Sammanfattning : According to the Fourth Assessment Report of Working Group I of the Intergovernmental Panel on Climate Change, the largest source of increased atmospheric CO2 concentration is fossil fuel use. The second largest is land-use change. LÄS MER

  4. 18. Energy efficiency measures in a kraft pulp mill converted to a biorefinery producing ethanol

    Författare :Rickard Fornell; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biorefinery; energy efficiency; process integration; biofuels; kraft pulp mill; ethanol;

    Sammanfattning : Large scale, sustainable production of ethanol biofuel will most likely require commercialization of processes using lignocellulosic raw materials. To date no commercial plant exists however, due to the difficulties in reaching production costs that can compete with 1st generation ethanol and fossil fuels. LÄS MER

  5. 19. Energy efficiency and carbon dioxide mitigation in building stocks-

    Författare :Erika Mata Las Heras; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis investigates the implementation of energy-saving measures (ESM) in existing building stocks from an energy systems perspective. The effects of the measures are assessed in terms of net and delivered energy levels, carbon dioxide (CO2) emissions, and the costs for implementing the measures. LÄS MER

  7. 20. Accelerate ageing of refuse-derived-fuel (RDF) fly ashes

    Författare :Evelina Brännvall; Britt-Marie Steenari; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Waste Science and Technology; Avfallsteknik;

    Sammanfattning : Ashes have properties that can be exploited in various applications, e.g. some ashes can be used in the construction of barriers in a landfill final top cover. LÄS MER
