  1. 1. Solar Shading for Low Energy Use and Daylight Quality in Offices: Simulations, Measurements and Design Tools

    Detta är en avhandling från LTH, Lund University

    Författare :Marie-Claude Dubois; Lunds universitet.; Lund University.; [2001]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggnadsteknik; Building construction; screens; venetian blinds; awnings; design tools; measurements; computer simulations; solar-protective glass; heating; cooling; visual comfort; daylighting; energy use; Shading devices; solar protection; Architecture; interior design; Arkitektur; inredningsarkitektur; Energy research; Energiforskning;

    Sammanfattning : This thesis investigates the impact of solar shading devices on energy use and daylight quality in office rooms. The impact on energy use is analysed through computer simulations with the dynamic energy simulation program Derob-LTH while the impact on daylight quality is investigated through measurements in full-scale experimental office rooms and simulations with the program Radiance.

    Sammanfattning : Popular Abstract in Swedish Denna avhandling handlar om energieffektiva fönstersystem i svenska byggnader. Simuleringar av energianvändningen har gjorts för både småhus och kontor för att bedöma effekterna av olika fönsterval på energibehov och inneklimat. LÄS MER

  3. 3. Novel and ancient technologies for heating and cooling buildings

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Sofiane Amara; Luleå tekniska universitet.; [2011]
    Nyckelord :Heating cooling; design; solar energy; simulation; optical fiber; light concentration; Fouggara; Earth sciences - Atmosphere and hydrosphere sciences; Geovetenskap - Atmosfärs- och hydrosfärsvetenskap; Vattenteknik; Water Resources Engineering;

    Sammanfattning : The basic issue of this thesis concerns one of the fundamental problems of the future of our society: How to meet the energy requirements for a large and growing world population while preserving our environment? This question is important for the world and the answers are complex and interwoven.Conventional energy sources, fossil and fissile, are polluting in the present and in the future: they erode the environment and their resources are limited.

  4. 4. Skin cancer prevention : Behaviours related to sun exposure and early detection

    Detta är en avhandling från Stockholm : Karolinska Institutet, Department of Oncology-Pathology

    Författare :Richard Bränström; Karolinska Institutet.; Karolinska Institutet.; [2003]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Skin cancer; malignant melanoma; sun exposure; sunburn; sun protection; prevention; early detection;

    Sammanfattning : Skin cancer is an emerging public health problem in Sweden. Even though the most important risk factor for the development of skin cancer - sun exposure - is known, the incidence of skin cancer is still increasing. Every year approximately 30,000 people in Sweden are diagnosed with skin cancer and approximately 400 die of this condition. LÄS MER
