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

    University essay from Lunds universitet/Institutionen för arkitektur och byggd miljö; Lunds universitet/Avdelningen för Energi och byggnadsdesign

    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. Energy and Circadian Assessment of a Combination Between Integrative Lighting and Daylight Harvesting

    University essay from Lunds universitet/Institutionen för arkitektur och byggd miljö; Lunds universitet/Avdelningen för Energi och byggnadsdesign

    Author : Ribhi Attar; Omar Al Mawla; [2021]
    Keywords : ALFA; Circadian Entrainment; Correlated Colour Temperature; Cortisol; Daylighting; Daylight Harvesting; Energy efficiency; Integrative lighting; Intrinsically photosensitive retinal ganglion cells; Melatonin; Melanopic Lux; Photopic Lux; Spectral Power Distribution; Technology and Engineering;

    Abstract : This study deals with the health and wellbeing of humans who work in offices as well as the energy use for the lighting. The focus is on how integrative lighting and daylight harvesting can be combined in an attempt to reduce the energy consumption while still eliciting a circadian response for the workers. READ MORE

  4. 3. PLANNING FOR SOLAR ACCESS.

    University essay from Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

    Author : Alejandro Manso Covarrubias; [2021]
    Keywords : Urban planning; daylight; solar access; Lund; Helsingborg; observations.; Technology and Engineering;

    Abstract : Swedish cities are getting denser. People spend a lot of time indoors, it therefore becomes important to guarantee daylight availability and solar access in buildings, in order to save energy and ensure human well-being. However, this becomes important in the case of outdoor spaces as well. READ MORE

  5. 4. UAV based hyperspectral grassland monitoring in an alpine shallow erosion area : lessons learnt from classifying vegetation indicating shallow erosion risk

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : John Peitz; [2019]
    Keywords : Physical Geography; Ecosystem Analysis; Shallow Erosion; Blaiken; UAV; Hyperspectral Imaging; Alps; Grassland; Spectral Signatures; Geomatics; Earth and Environmental Sciences;

    Abstract : UAV based hyperspectral grassland monitoring in an alpine shallow erosion area Recent research in the Alps found that a reduction in grassland management is correlated to an increase in a certain type of shallow erosion areas called blaiken. This change also entails changes to the dominant grassland vegetation. READ MORE

  6. 5. Daylighting and sunlighting in street canyons. A quantitative research on the visual perception and in-situ daylight measurements of four urban canyons in Copenhagen.

    University essay from Lunds universitet/Institutionen för arkitektur och byggd miljö; Lunds universitet/Avdelningen för Energi och byggnadsdesign

    Author : Olesja Lami; [2019]
    Keywords : daylighting; sunlighting; urban canyon; visual perception; visual comfort; Technology and Engineering;

    Abstract : “Light creates ambience and the feel of a place, as well as the expression of a structure.” Le Corbusier With the current urban pressure and large waves of immigration, cities are facing an increase in population and therefore urban densification. This increase in building quantities affects daylight reaching the public space. READ MORE
