    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

  3. 3. 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

  4. 4. Daylighting and Electric Lighting Integration in the Retail Sector

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

    Författare :Rafael Campama Pizarro; [2019]
    Nyckelord :daylighting; electric lighting; lighting controls; integration; human centric lighting; circadian potential; melanopic lux; non-visual effects; energy saving; retail; case study; IEA-SHC; furniture store; shopping experience.; Arts and Architecture; Earth and Environmental Sciences;

    Sammanfattning : The retail sector represents 11% of the GDP and employs 15% of the workforce in the European Union. To tackle growth of e-commerce, physical retail stores need to be reviewed; both to decrease operating costs, increase productivity and to make the shopping experience more appealing. LÄS MER
