   Detta är en avhandling från Department of Environmental and Energy Systems Studies, Lund university

   Författare :Jürgen Salay; [1999]
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; implementation; sustainable energy; renewable energy; electricity production; power industry; Baltic states; Poland; transition; sulphur dioxide; air pollution; energy efficiency; Energy; energy use; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp; Energy research; Energiforskning;

   Sammanfattning : This thesis is a study of how energy use and air pollution in Poland, Estonia, Latvia and Lithuania have been affected by the economic transition after 1989. It consists of six articles, which examine three different aspects of these changes. LÄS MER

3. 2. Dynamics of Energy Systems - Methods of analysing technology change

   Detta är en avhandling från Environmental and Energy Systems Studies, Lund university

   Författare :Lena Neij; [1999]
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy research; evaluation; market transformation; PV modules; wind power; experience curves; air-distribution; lighting; vintage models; sustainable energy; renewable energy; energy efficiency; Energy; energy system; Energiforskning; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp;

   Sammanfattning : Technology change will have a central role in achieving a sustainable energy system. This calls for methods of analysing the dynamics of energy systems in view of technology change and policy instruments for effecting and accelerating technology change. In this thesis, such methods have been developed, applied, and assessed. LÄS MER

4. 3. The Non-Energy Benefits of Industrial Energy Efficiency Investments and Measures

   Detta är en avhandling från Environmental and Energy Systems Studies, Lund university

   Författare :Therese Nehler; Patrik Thollander; Elin Svensson; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial energy efficiency; energy efficiency measures; energy efficiency investments; non-energy benefits; compressed air;

   Sammanfattning : Improved industrial energy efficiency is viewed as an important means in the reduction of CO2 emissions and climate change mitigation. Various energy efficiency measures for improving energy efficiency exists, but even evaluated as cost-effective, there seems to be a difference between the energy efficiency measures that theoretically could be undertaken and which measures that actually are realised.

5. 4. Low-energy buildings energy use, indoor climate and market diffusion

   Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

   Författare :Johannes Persson; Stefan Grönkvist; Svend Svendsen; [2014]
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; building energy simulations; energy efficiency gap; energy use; indoor climate; low-energy buildings;

   Sammanfattning : Low-energy buildings have, in recent years, gained attention and moved towards a large-scale introduction in the residential sector. During this process, national and international criteria for energy use in buildings have become stricter and the European Union has through the Energy Performance of Buildings Directive imposed on member states to adapt their building regulations for ‘Nearly Zero Energy Buildings’, which by 2021 should be standard for new buildings.

7. 5. Energy Efficiency Improvements of Tumble Dryers -Technical Development, Laundry Habits and Energy Labelling

   Detta är en avhandling från Karlstad : Karlstad University

   Författare :Lena Stawreberg; Lars Nilsson; Jonas Berghel; Roger Renström; Björn Palm; [2011]
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; drying; domestic; energy efficiency; textile; energy labelling standard; TECHNOLOGY Engineering mechanics Mechanical and thermal engineering Thermal energy engineering; TEKNIKVETENSKAP Teknisk mekanik Mekanisk och termisk energiteknik Termisk energiteknik; Miljö- och energisystem; Environmental and Energy Systems;

   Sammanfattning : Tumble dryers are becoming more and more common in ordinary households as a complement to the washing machine. Tumble dryers offer a fast drying cycle independent on weather conditions and require small space. They do, however, considering the large number of units use a large amount of electricity. LÄS MER
