   Author : Rebecka Ståhl; Parvathy Biju; [2023]
   Keywords : 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;

   Abstract : 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. READ MORE

3. 2. PERCEIVED BRIGHTNESS OF COLORED LIGHT : A study about the perceived brightness of near-monochromatic light in comparison to neutral white light

   University essay from Jönköping University/JTH, Byggnadsteknik och belysningsvetenskap

   Author : Razan Albunayah; Sofia C Lindén; [2023]
   Keywords : colored light; perceived brightness; spectral distribution; visual field; white light;

   Abstract : Recently, there has been a notable rise in the use of colored lighting for both indoor andoutdoor spaces. This trend necessitates a clear understanding of the principles behindselecting lighting levels that are both ergonomic and energy efficient. The objective ofthis study was to establish guidelines for planning colored light. READ MORE

4. 3. Impact of nanoparticle plasmons on photoluminescense and upconversion processes in ZnO

   University essay from Uppsala universitet/Solcellsteknik; Uppsala universitet/Fysikalisk kemi

   Author : Axel Gudmundsson; [2023]
   Keywords : Photoluminescence; Upconversion; Plasmons; ZnO;

   Abstract : The increasing prevalence of glass windows in modern buildings has raised the demand for solar control windows that possess climate-appropriate properties. Glass windows made of abundant and low-cost materials which can both decrease the heating energy consumption as well as enhance the light climate indoors would sufficiently meet the goals of economical yet uplifting buildings.

5. 4. Optimization of Light Conditions in a Greenhouse Environment : Reducing energy consumption and increasing yield using mechatronics

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Elias Mahjoub; [2022]
   Keywords : Indoor growing; Light-emitting diode; Mechatronics; Sustainability; Vertical Farming.; Inomhusodling; Lysdiod; Mekatronik; Hållbarhet; Vertikalt Jordbruk;

   Abstract : The present thesis explores the possibilities of reducing electrical energy consumption in a greenhouse environment through the construction a demonstrator system. The demonstrator system is imagined to be used in a vertical farming setup and is fully automated. The system achieves two main actions. READ MORE

6. 5. Improving building heating efficiency using machine learning : An experimental study

   University essay from Blekinge Tekniska Högskola/Institutionen för industriell ekonomi

   Author : Niklas Lindberg; Carl Magnusson; [2021]
   Keywords : Building Energy Consumption; Building energy efficiency; Building specific heating Curve; Machine learning; Artificial Neural Network;

   Abstract : While global efforts are made to reduce the emission of greenhouse gases and move towards a more sustainable society, the global energy demand is continuing to increase. Building energy consumption represents 20-40% of the world's total energy use, and Heating, Ventilation, and Air Conditioning (HVAC) answer for around 50% of this amount. READ MORE
