2. 1. Light Rhythms : Exploring the Perceptual and Behavioural Effects of Daylight and Artificial Light Conditions in a Scandinavian Context

   Author : Federico Favero; Roberto Bresin; Arne Lowden; Ute Besenecker; Sergio Altomonte; KTH; []
   Keywords : HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; Lighting design; Context; Light; Behaviour; Perception of light; Perception of time; Associative aspects; Architecture; Daylight; Media Technology; Medieteknik;

   Abstract : This compilation thesis collects multidisciplinary work on the study of the impact of light rhythms on perception and behaviour. The thesis was structured to answer and discuss the questions: “How does a person feel and behave inan illuminated space?” and “Do variable light conditions influence perception, appraisal and motion?”.

4. 2. Daylight Influence on Colour Design : Empirical Study on Perceived Colour and Colour Experience Indoors

   Author : Maud Hårleman; Jadwiga Krupinska; José Luis Caivano; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; architecture; interior colouring; spatial character; natural daylight; verbal description; colour reference box; Architecture; Arkitektur;

   Abstract : It is known that one and the same interior colouring will appear different in rooms with windows facing north or facing south, but it is not known how natural daylight from these two compass points affects perceived colour and the ways in which colour is experienced. The objective is to describe the perceived colours to be expected in rooms with sunlight and diffused light, and thus develop a tool for colour design. READ MORE

5. 3. Energy Efficient Window Systems. Effects on Energy Use and Daylight in Buildings

   Author : Helena Bülow-Hübe; Avdelningen för Energi och byggnadsdesign; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; simulation; thermal transmittance; solar energy transmittance; shading device; solar protection; cooling; heating; energy demand; building; low-emittance coating; window; glazing; comfort; user aspects; operative temperature; Architecture; Building construction; Byggnadsteknik; daylight; perception; interior design; Arkitektur; inredningsarkitektur; Energy research; Energiforskning;

   Abstract : This thesis deals with energy-efficient windows in Swedish buildings. Parametric studies were performed in the dynamic energy simulation tool Derob-LTH in order to study the effects of window choices on energy use and indoor climate for both residential and office buildings.

6. 4. Long-term Properties of Sustainable Polymeric Materials : Mechanical Recycling and Use of Renewable Resources

   Author : Emma Strömberg; Sigbritt Karlsson; Amparo Ribes-Greus; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sustainable materials; mechanical recycling; polyolefin; reprocessing; accelerated ageing; chromatography; biofilm; microenvironment chamber; environmental degradation; biocomposite; nanocomposite; Polymer chemistry; Polymerkemi;

   Abstract : New strategies for management of the accumulating amounts of plastic waste are required, to achieve a sustainable development in terms of material production and use. After service life, the materials should be recovered and recycled efficiently to provide a valuable resource for future applications. READ MORE

7. 5. Winter behaviour of stream salmonids: effects of temperature, light, and ice cover

   Author : Johan Watz; Larry Greenberg; Eva Bergman; John Piccolo; Svein Jakob Saltveit; Karlstads universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; stream salmonids; winter behaviour; efftect of temperatur; light; ice cover; environment; fish populations; Biology; Biologi;

   Abstract : In boreal streams, stream salmonids typically face low water temperatures and variable ice conditions during winter, and thus stream salmonids are expected to use different behavioural strategies to cope with these environmental conditions. The studies presented in this thesis explore how temperature, light intensity, and surface ice affect salmonid behaviour, with focus on drift-feeding and ventilation rates. READ MORE
