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

   Författare :Pimkamol Mattsson; Institutionen för arkitektur och byggd miljö; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

3. 2. 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; 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

4. 3. Supporting evidence-based design using lighting simulations : A framework for lighting simulation of visual comfort in building design

   Författare :Anahita Davoodi; Myriam Aries; Peter Johansson; Thorbjörn Laike; John Mardaljevic; Jönköping University; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lighting quality; visual comfort; lighting simulation; evidence-based design; field study; post-occupancy evaluation; Ljuskvalitet; visuell komfort; ljussimulering; evidensbaserad design; fältstudie; brukarutvärderingar;

   Sammanfattning : This research aims to integrate lighting simulation into the evidence-based design process for achieving improved lighting outcomes in built environments with a particular emphasis on visual comfort analysis in office settings. The objectives of the study include 1) understanding the current usage of lighting simulation tools, learning designers’ experiences' and needs, 2) providing a conceptual framework to integrate the use of lighting simulation in the evidence-based design (EBD) process, 3) testing the usage of the conceptual framework (named EBD-SIM) through two field studies.

5. 4. 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

7. 5. 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; 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.
