1. 1. Influence of Varying Electric Light Distribution on Melanopic Equivalent Daylight Illuminance and Lighting Energy Use

   Master-uppsats, Lunds universitet/Institutionen för arkitektur och byggd miljö; Lunds universitet/Avdelningen för Energi och byggnadsdesign

   Författare :Rebecka Ståhl; Parvathy Biju; [2023]
   Nyckelord :Alertness; Circadian Entrainment; Clear Sky; Correlated Colour Temperature; Daylighting; Direct Electric Lighting; Direct-Indirect Electric Lighting; Energy-Efficiency; Grasshopper; Integrative Lighting; LARK 2.0; Melanopic Equivalent Daylight Illuminance; Overcast Sky; Photopic Illuminance; Spectral Power Distribution.; Technology and Engineering;

   Sammanfattning : Human beings in modern society spend more than 90% of their time indoors to live, work, and socialize. To improve health, quality of life and task performance, integrative lighting is designed to give the right light at the right time at the eye to stimulate circadian entrainment. LÄS MER

3. 2. Life Cycle Perspective on School Buildings’ Energy Retrofitting

   Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

   Författare :Maryam Kafashtehrani; [2022]
   Nyckelord :School; building; LCA; IDA-ICE; energy retrofitting; insulation; ventilation; photovoltaic; PV; GHG;

   Sammanfattning : The building sector contributes substantial energy consumption and greenhouse gas (GHG) emissions. Energy efficiency is the main driver for the mitigation of climate change. Schools are placed with high energy consumption and GHG emitting. LÄS MER

   Sammanfattning : Driving is one of the most common and preferred forms of transport used in our actual society. However, according to studies, it is also one of the most dangerous. One solution to increase safety on the road is applying technology to automate and prevent avoidable human errors. LÄS MER

5. 4. Lighting to enhance cooperative learning in classrooms

   Magister-uppsats, KTH/Ljusdesign

   Författare :Tishita Aggarwal; [2022]
   Nyckelord :Cooperative learning; flexibility; variable lighting; learning performance; classroom lighting;

   Sammanfattning : Cooperative learning refers to teaching methods that encourage students to work together in small groups to help each other learn educational content. In Sweden, cooperative learning methods are used in classrooms as an educational approach to organize classroom activities into academic and social learning experiences. LÄS MER

7. 5. Put the Light Where it is Needed

   Magister-uppsats, KTH/Ljusdesign

   Författare :Christofer Blixt; [2020]
   Nyckelord :Lighting Design Method for Urban Green Areas; Conceptual Design Proposal; Level of Contrast; Level of Light; Distribution of Light; Aesthetic Qualities; Perceived Safety;

   Sammanfattning : In this thesis I have analyzed how the phenomenon level of contrast, a consequence of the relation between level of light and distribution of light, works within urban green areas. For this particular site, the too high level of contrast is a result of the high level of light distributed 1) in the direction of oncoming pedestrians and 2) in a single zone of light and 3) on a too condensed surface area and 4) in a space with multiple vertical elements (in a dark space with low reflectance values).
