1. 16. Energy efficiency in heritage buildings : Conservation approaches and their impact on energy efficiency measures

   Författare :Tomas Örn; Agatino Rizzo; Sofia Lidelöw; Andrea Luciani; Elena Lucchi; Luleå tekniska universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy efficiency heritage buildings; Arkitektur; Architecture;

   Sammanfattning : The impeding climate change challenge urges for a reduction of energy use in the built environment. Buildings account for nearly 40% of the total energy use and about 35% of the greenhouse gas emissions in Europe. LÄS MER

3. 17. Process integration to increase woody biomass utilization for energy purposes

   Författare :Sennai Mesfun; Francesco Fantozzi; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

   Sammanfattning : Woody biomass is an abundant renewable energy resource in Sweden, and the Swedish government has been promoting research and development programs for the exploitation of this resource as a mean to meet the targets on the reduction of the carbon dioxide emissions from the industrial, energy and transportation sectors. This thesis aims at expanding the knowledge on the efficient utilization of the available woody biomass, so that a larger amount of this renewable resource can be used for energy purposes. LÄS MER

7. 20. System Effects of Improved Energy Efficiency in Swedish District-Heated Buildings

   Författare :Magnus Åberg; Ewa Wäckelgård; Henrik Lund; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; district heating; carbon dioxide emissions; building energy efficiency; combined heat and power; Engineering Science; Teknisk fysik;

   Sammanfattning : To alleviate global warming, European-Union member states must reduce primary energy use, emit less carbon dioxide (CO2), and increase renewable energy use. Buildings constitute a great potential for energy savings, but saving energy in district-heated buildings influences combined heat and power (CHP) production, other electricity generation, and global CO2 emissions.
