  1. 1. Building Integration of Solar Energy. A Multifunctional Approach

    Författare :Andreas Fieber; Avdelningen för Energi och byggnadsdesign; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis consists of two parts. The first part deals with building integrated solar energy, mainly from an architectural point of view. LÄS MER

  3. 2. Calculation and Measurement Methods for the Performance of Solar Collectors. Models of Flat Plate Collectors, Transparent Insulation and Efficiency Factors

    Författare :Bengt Hellström; Avdelningen för Energi och byggnadsdesign; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transparent insulation; Test method; Calculation method; Concentrating collector; Efficiency factor; Fin efficiency; Flat plate collector; Heat conductivity; Honeycomb; Measurement method; Performance; Solar transmittance; Solar collector; Collector model; Energy research; Energiforskning;

    Sammanfattning : This thesis deals with models of flat plate collectors, transparent insulation and efficiency factors. An equation for the energy output from a glazed flat plate collector is derived by modelling the collector efficiency factor, F´ as the sum of a constant and a temperature dependent part. LÄS MER

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

    Författare :Helena Bülow-Hübe; Avdelningen för Energi och byggnadsdesign; []
    Nyckelord :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;

    Sammanfattning : 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.

  5. 4. Evaluation of new active technology for low-energy houses

    Författare :Henrik Davidsson; Avdelningen för Energi och byggnadsdesign; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low-quality heat; hybrid ventilation; heat recovery; active house; solar window; PV T hybrid; building integration; TRNSYS;

    Sammanfattning : Using energy at low-quality levels opens up new possibilities for low-energy houses. Low-quality energy can be heat at a temperature that is close to that of its surrounding, and can be used, for example, to pre-heat ventilation air or domestic hot water. LÄS MER

  7. 5. Planning for Solar Buildings in Urban Environments

    Författare :Jouri Kanters; Avdelningen för Energi och byggnadsdesign; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; architecture; design tool; design process; solar energy; urban planning; photovoltaics; solar thermal; building integration; density; net zero energy buildings; interviews; parametric studies; action research;

    Sammanfattning : Energy use in buildings accounts for a significant proportion of the total energy use in many countries. While past and current buildings have solely been energy consumers, future buildings will, besides using less energy, also need to produce (part of ) the required energy on site with renewables.
