    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. Building Orientation and Non-Image Forming Effects of Light. Connecting Simulation and reality in the case of Iggesund School.

    Magister-uppsats, KTH/Ljusdesign

    Författare :Gregor Ruta; [2022]
    Nyckelord :Alfa-Opic Metrics; Spectral Diet; OWL – Occupant Well-being through Lighting; Chronobiology; Daylight; Circadian Rhythmes; Melatonin; Vision;

    Sammanfattning : In recent years there has been an increase in the number of apartments in Sweden. The officials are estimating that approximately 1000 primary schools need to be built to meet the 20% increase in students. Facing the rising demand; my thesis makes a contribution to sustainable school design via optimisation of the building orientation. LÄS MER

    Sammanfattning : Nowadays, people spend 90% of their time indoors, thus creating a healthy indoor environment for occupants is of great importance. Lighting in office spaces is an important aspect when it comes to occupant health and well-being. LÄS MER

  5. 4. Lighting Evaluation and Design for the Stockholm Metro System Based on Current Models for Non-visual Responses

    Magister-uppsats, KTH/Ljusdesign

    Författare :Tong Liu; [2020]
    Nyckelord :Non-visual Effects; Circadian Lighting; Equivalent Melanopic Lux EML ; Circadian Stimulus CS ; Melanopic Equivalent Daylight Illuminance M-EDI ; Stockholm Metro System; Light-Emitting Diode LED ;

    Sammanfattning : Light has a wide and profound non-visual impact on the human body. It is related to the suppression or synthesis of a hormone called melatonin which regulates the human circadian clock. In Nordic countries like Sweden, lack of natural light in winter may lead to negative health effects such as circadian disorders or depression. LÄS MER
