1. 1. Energy Efficiency in Shopping Malls : Some Aspects Based on a Case Study

   Författare :Sofia Stensson; Jan-Olof Dalenbäck; Per Fahlén; Monica Axell; Jeffrey Spitler; Sweden Chalmers University of Technology; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Shopping mall; energy use; energy efficiency; HVAC system; load patterns; case study; regulatory requirements; building code; and energy declarations;

   Sammanfattning : The building sector accounts for approximately 40 percent of our energy use. To reach existing environmental targets energy use will have to be reduced in all building types. At the European level, the main legislative instrument for improving the energy efficiency of the building stock is the Energy Performance of Buildings Directive (EPBD). LÄS MER

3. 2. Hydro-Kinetic Energy Conversion : Resource and Technology

   Författare :Mårten Grabbe; Mats Leijon; Cameron Johnstone; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tidal energy; renewable energy; vertical axis turbine; permanent magnet generator; resource assessment; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

   Sammanfattning : The kinetic energy present in tidal currents and other water courses has long been appreciated as a vast resource of renewable energy. The work presented in this doctoral thesis is devoted to both the characteristics of the hydro-kinetic resource and the technology for energy conversion. LÄS MER

4. 3. The role of industrial energy management in the transition toward sustainable energy systems : Exploring practices, knowledge dynamics and policy evaluation

   Författare :Mariana Andrei; Patrik Thollander; Anna Sannö; Patrik Rohdin; Kornelis Blok; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy management; Practices; Transition to sustainable energy systems; Knowledge-creation; Process innovation; Incremental and radical innovations; Voluntary initiatives; Digital technologies for energy efficiency;

   Sammanfattning : Mitigating climate change represents one of the most pressing challenges of our time. The EU has set the goal of reaching climate neutrality by 2050. The transition of manufacturing organizations is essential in reaching the EU’s goal, since industry accounts for circa 25% of the total final energy use and about one-fifth of EU’s GHG emissions.

5. 4. Using Low Energy Light to Enable High Energy Photochemistry

   Författare :Wera Larsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; triplet-triplet annihilation; solar energy conversion; photochemistry; molecular photoswitches; photochemical upconversion; triplet sensitization; fluorescence modulation;

   Sammanfattning : Manipulating light to meet human needs is pivotal in various research fields and technological applications, ranging from solar energy conversion to photodynamic therapy and fluorescence imaging of cells and tissues. This thesis addresses the spectral mismatches between available light and the specific energy requirements of target photochemical reactions by employing low-energy light to control high-energy photochemistry.
