  1. 1. Lighting Control Systems for Energy Saving and User Acceptance: State-of-the-art and future directions

    Author : Niko Gentile; Energi och ByggnadsDesign; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; SAMHÄLLSVETENSKAP; ENGINEERING AND TECHNOLOGY; SOCIAL SCIENCES; Indoor lighting; lighting control system; lighting control; energy saving; energy efficiency; user acceptance; human factor; occupancy strategies; absence sensor; presence sensor; lighting switch; manual switch; daylight harvesting system; daylight-linked system; photoelectric dimming; photosensor.;

    Abstract : Lighting accounts for one-fifth of global electricity use. In Sweden, energy demand for lighting corresponds to 20% of the total electricity use in office buildings. Lighting retrofit measures are considered to be among the most cost-efficient way to reduce energy use in buildings. READ MORE

  2. 2. Industrial electricity demand and energy efficiency policy

    Author : Eva Henriksson; Luleå tekniska universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Nationalekonomi;

    Abstract : This dissertation consists of an introduction and five self-contained papers addressing the issues of industrial electricity demand and the role of energy efficiency policy. An important context for the study is the increased interest in so-called voluntary energy efficiency programs in which different types of tax exemptions are granted if the participating firms carry out energy efficiency measures following an energy audit.

  3. 3. Natural gas in the Asian Pacific region : market behavior and the Japanese electricity market

    Author : Bo Jonsson; Luleå tekniska universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Nationalekonomi;

    Abstract : This dissertation consists of four main chapters, all related to the Asian Pacific natural gas market, and the role of the Japanese electricity sector. The natural gas market in Asia Pacific is heavily dependent on the demand from Japan, which imports around 75% of the gas traded as LNG (liquefied natural gas) in the region. READ MORE

  4. 4. Demand Side Response : Exploring How and Why Users Respond to Signals Aimed at Incentivizing a Shift of Electricity Use in Time

    Author : Isak Öhrlund; Cajsa Bartusch; Peter Juslin; Mikael Larsson; Jacopo Torriti; Uppsala universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; TEKNIK OCH TEKNOLOGIER; SAMHÄLLSVETENSKAP; ENGINEERING AND TECHNOLOGY; SOCIAL SCIENCES; Demand response; Electricity use flexibility; Time-varying rate; Dynamic pricing; Price-based program; Time-of-use; Demand charge; Real-time pricing; Real-time feedback; Prosumer; Non-price signal; Non-price incentive; Engineering Science with specialization in industrial engineering and management; Teknisk fysik med inriktning mot industriell teknik;

    Abstract : With increased weather-dependent electricity production and electrification at the heart of the ongoing transition away from fossil fuels, peaks in electricity demand are set to increase and become increasingly difficult to meet, which threatens the functioning of the electric power systems that our society depends on. Time-varying electricity rates, which aim to incentivize electricity users to shift their electricity use in time, have been proposed as a key instrument in alleviating grid imbalances and bottlenecks.

  5. 5. Design and analysis of solid oxide electrolysis-based systems for synthetic liquid fuels production

    Author : Mahrokh Samavati; Andrew R. Martin; Alberto Traverso; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid oxide electrolyser; Entrained gasification; Fischer-Tropsch process; Thermodynamic analysis; Economy; Emission saving; Policy; Energiteknik; Energy Technology;

    Abstract : During the past decades, considerable attention has been dedicated to renewable energy systems. This is due to the increased awareness regarding greenhouse gas emissions as well as limits of the future availability and reliability of conventional energy and power systems. READ MORE
