  1. 1. Energy Analysis of the Closed Greenhouse Concept Towards a Sustainable Energy Pathway

    Författare :Amir Vadiee; Viktoria Martin; Halime Paksoy; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal energy storage; closed greenhouse; energy analysis; energy management; SRA - Energy; SRA - Energi;

    Sammanfattning : The closed greenhouse is an innovative concept in sustainable energy management. The closed greenhouse can be considered as a large commercial solar building. In principle, it is designed to maximize the utilization of solar energy through seasonal storage. In a fully closed greenhouse, there are not any ventilation windows. LÄS MER

  2. 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

  3. 3. 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.

  4. 4. Energy analysis for sustainable mega-cities

    Detta är en avhandling från Stockholm : KTH

    Författare :Aumnad Phdungsilp; Björn Palm; Ivo Martinac; Charles Heaps; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Asian mega-cities; energy demand; metabolism of cities; energy modeling; sustainable energy; energy planning; multi-criteria decision-making; TECHNOLOGY Engineering mechanics Mechanical and thermal engineering Mechanical energy engineering; TEKNIKVETENSKAP Teknisk mekanik Mekanisk och termisk energiteknik Mekanisk energiteknik;

    Sammanfattning : ABSTRACTCities throughout Asia have experienced unprecedented economic development over the past decades. In many cases this has contributed to their rapid and uncontrolled growth, which has resulted in a multiplicity of problems, including rapid population increase, enhanced environmental pollution, collapsing traffic systems, dysfunctional waste management, and rapid increases in the consumption of energy, water and other resources.

  5. 5. Improving Ship Energy Efficiency through a Systems Perspective

    Detta är en avhandling från Stockholm : KTH

    Författare :Francesco Baldi; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modelling; shipping; exergy analysis; energy systems; energy efficiency; energy analysis; systems analysis;

    Sammanfattning : The last years have been particularly challenging for the shipping industry. Fuel prices have increased to levels only seen during the oil crisis in the 70's, and environmental regulations have grown much stricter than in the past. Climate change, at a global level, is going to become a major threat to society. LÄS MER
