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

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Amir Vadiee; KTH.; [2011]
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 2. National Energy System Modelling for Supporting Energy and Climate Policy Decision-making The Case of Sweden

    University dissertation from Göteborg : Chalmers University of Technology

    Author : Anna Krook-Riekkola; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik; climate policy; district heating; TIMES-Sweden; ancillary benefits; energy system models; cross-border trade; energy-economics; soft-linking.; CHP; system analysis;

    Abstract : Energy system models can contribute in evaluating impacts of energy and climate policies. The process of working with energy system models assists the understanding of the quantita¬tive relationships between different parts of the energy system and between different time periods, under various assumptions.

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

    University dissertation from Environmental and Energy Systems Studies, Lund university

    Author : Lena Neij; Lunds universitet.; Lund University.; [1999]
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 4. Buoy and Generator Interaction with Ocean Waves Studies of a Wave Energy Conversion System

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Simon Lindroth [formerly Tyrberg]; Uppsala universitet.; [2011]

    Abstract : On March 13th, 2006, the Division of Electricity at Uppsala University deployed its first wave energy converter, L1, in the ocean southwest of Lysekil. L1 consisted of a buoy at the surface, connected through a line to a linear generator on the seabed. READ MORE

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

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Johannes Persson; KTH.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; building energy simulations; energy efficiency gap; energy use; indoor climate; low-energy buildings;

    Abstract : 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.
