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

   Författare :Niko Gentile; Institutionen för arkitektur och byggd miljö; []
   Nyckelord :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.;

   Sammanfattning : 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. LÄS MER

3. 2. Lighting simulation for a more value-driven building design process

   Författare :Anahita Davoodi; Thorbjörn Laike; Peter Johansson; Annika Moscati; Jönköping University; []
   Nyckelord :lighting simulation; lighting design; lighting quality; energy efficiency; perception;

   Sammanfattning : Concerns about global warming are increasing, hence, the urgency to cut carbon emissions. Reducing energy consumption, including lighting energy, is seen as the primary solution. Yet, solving the environmental factor should not come at the cost of other pillars of sustainable development. LÄS MER

4. 3. Complicated Shadows : the Aesthetic Significance of Simulated Illumination in Digital Games

   Författare :Simon Niedenthal; Malmö högskola; []
   Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; Interaction design; Game design; Game studies; Game aesthetics; Game lighting; Lighting design; Digital games; Lighting; Simulated Illumination;

   Sammanfattning : A common feature of many digital games is that they are played in a simulated 3D environment, a game world. Simulated illumination is the lighting designed into a game world. This thesis explores the influence of simulated illumination in digital games upon the emotion and behavior of the player. LÄS MER

5. 4. Lighting Control Systems to Save Energy in the non-Residential Sector : State-of-the-art, Field Studies, and Simulations

   Författare :Niko Gentile; Institutionen för arkitektur och byggd miljö; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; 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;

   Sammanfattning : 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.

7. 5. Urban outdoor lighting : Pedestrian perception, evaluation and behaviour in the lit environment

   Författare :Johan Rahm; Institutionen för arkitektur och byggd miljö; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Outdoor lighting; Street lighting; Pedestrian; Walking; Walkability; Perceived safety; Urban design; Perception; Environmental psychology; Elderly; Mobility;

   Sammanfattning : Walking plays an essential role in sustainable transport systems, as nearly all journeys in the urban environment incorporate walking in one way or another. In parts of the world, for long periods of the year, seasonal variation in daylight hours means that pedestrians must rely on outdoor lighting to make cities accessible after dark. LÄS MER
