  2. 21. 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.

  4. 22. Indoor Environment and User Perception. A Field Study in a Hospital Ward

    Author : Jennie Skoog; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; indoor environment; thermal climate; hospital ward; indoor air quality; comfort; perception; sound; light;

    Abstract : The research on indoor environment has become more important and extensive the last decades. There is, however, a lack of studies made in buildings with two or more distinct groups of people. This study deals with hospital wards, which are a prime example of buildings occupied by more than one homogenous group of people. READ MORE

  5. 23. Evaluation of thermal comfort of head gear : a method to measure heat transfer characteristics

    Author : Xiaoxiong Liu; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Work Environment; Industriell produktionsmiljö;

    Abstract : This study was carried out within the research project "Thermal properties of protective helmets - improvement, validation and standardization of a measurement method" which was a continuation of a research project being carried out since 1992 at the Division of Industrial Ergonomics, Department of Human Work Sciences, Luleå University of Technology, Sweden, with co-operation of the Department of Ergonomics, National Institute for Working, Life (NIWL), Solna, Sweden. A method was developed for measuring the evaporative heat transfer properties of helmets, based on the results of a thorough literature survey. READ MORE

  6. 24. A Systematic Approach to Integrated Building Performance Assessment and Visualisation

    Author : Samer Hassanie; Ivo Martinac; Holger Wallbaum; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal comfort; energy consumption; building certifications; occupancy; modeling; presence; pattern recognition; Demand controlled ventilation; Indoor thermal environment; Occupancy; Time response; Energy use; Civil and Architectural Engineering; Byggvetenskap;

    Abstract : The aim of this project was to develop a holistic approach to building-performance assessment without limiting it to energy use (usually expressed in kWh/m2/year), but rather include more parameters that represent the following aspects: Economic, environmental, and quality of service provided to the occupant/client. If it can be shown that buildings can be operated not only in an energy-efficient way, but also in a way that takes into consideration the needs of the occupants, a case could be built that a higher quality of indoor environment does not necessarily mean a higher economic impact.

  7. 25. Some Factors Influencing Thermal Comfort and Air Quality in Residential Buildings. Field Measurements and Laboratory Tests

    Author : Ulf Krüger; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ventilation; air intakes; thermal comfort evaluation; air velocity; indoor air quality; air supply devices; occupation zone; air temperature fluctuations;

    Abstract : The main prerequisite for applying a specific ventilation system in residential buildings is that the demands set upon the indoor air quality and thermal climate can be satisfied. If this cannot be guaranteed using a simple exhaust system, a system with treated supply air, i.e. balanced ventilation, should be considered. READ MORE
