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

    University dissertation from Lund University, Faculty of Engineering

    Author : Niko Gentile; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; 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. Lighting Control Systems to Save Energy in the non-Residential Sector : State-of-the-art, Field Studies, and Simulations

    University dissertation from Division of Energy and Building Design

    Author : Niko Gentile; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; [2017-10-27]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Indoor lighting; lighting control system; lighting control; energy sav; energy eff; user acceptan; degree of acceptance; human factor; occupancy strategy; presence strategy; absence strategy; daylight harvesting; daylight-linked; daylight; photoelectric dimming; photosensor; manual switch; functional illumination; standby;

    Abstract : This thesis examines the energy-saving potential for lighting when using traditional indoor LCSs in non-residential buildings. In the study, an overarching theoretical framework is used that distinguishes between energy efficiency and energy saving, as well as between energy use for lighting and functional illumination.

  3. 3. Iterative Road Grade Estimation for Heavy Duty Vehicle Control

    University dissertation from Stockholm : KTH

    Author : Per Sahlholm; KTH.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; road grade; estimation; heavy duty vehicle; Kalman filter; automatic control; TECHNOLOGY Information technology Automatic control; TEKNIKVETENSKAP Informationsteknik Reglerteknik;

    Abstract : This thesis presents a new method for iterative road grade estimation based on sensors that are commonplace in modern heavy duty vehicles. Estimates from multiple passes of the same road segment are merged together to form a road grade map, that is improved each time the vehicle revisits an already traveled route. READ MORE

  4. 4. Do lighting control and user interface design matter to occupant behaviour? The case of optimal lighting use in non-residential buildings

    University dissertation from Stockholm : KTH

    Author : Pimkamol Mattsson; Lund University.; Lunds universitet.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; characteristic; design; energy reduction; energy-saving behaviour; lighting control; light switch; lighting use; non-residential building; perception; user interface;

    Abstract : The lowering of energy use from artificial lighting in buildings is vital to reaching the goal of reducing CO2 emissions. Hence, changes in individuals’ behaviours regarding lighting use have received increased attention. Feedback on energy use has often been used to change individuals’ behaviour. READ MORE

  5. 5. Fluorescence as a biological feedback signal for energy optimising spectra for greenhouse LED-illumination

    University dissertation from Stockholm : KTH

    Author : Linnéa Ahlman; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluorescence; Photosynthesis; Automatic control; Greenhouse illumination; LED lighting; Spectrum optimisation;

    Abstract : The introduction of LED-lighting for greenhouses has enabled new ways of controlling the light, both spectrum and intensity, to save energy and increase crop production. We have investigated a new method of automatically tuning the spectrum based on biological feedback. READ MORE
