  2. 16. Office illness : the worker, the work and the workplace

    Author : Berndt Stenberg; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Sick Building Syndrome; Indoor Air Syndrome; facial skin symptoms; constitutional factors; psychosocial factors; indoor air quality; outdoor air flow rate; electromagnetic conditions; VDT work;

    Abstract : The work started with the clinical observations in patients working in buildings with indoor air problems. Signs of seborrhoeic dermatitis, erythematous facial skin conditions and itching conditions on the trunk were noted. Another point of departure was the attribution of facial skin symptoms to VDT work by patients. READ MORE

  4. 17. 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. 18. The Sink-Effect in Indoor Materials : Mathematical Modelling and Experimental Studies

    Author : Peter Hansson; KTH; []
    Keywords : sink-effect; sorption; adsorption; diffusion; indoor air quality; volatile organic compounds; VOC; contaminants; building materials;

    Abstract : In this thesis the sink-effect in indoor materials wasstudied using mathematical modelling and experimental studies.The sink-effect is a concept which is commonly used tocharacterise the ability of different indoor materials to sorbcontaminants present in the indoor air. The sorption process ismore or less reversible, i.e. READ MORE

  6. 19. Removal of ultrafine particles by intermediate air filters in ventilation systems. Evaluation of performance and analysis of applications

    Author : Bingbing Shi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; measurements; ultrafine particles; lifetime cost; indoor air quality; health effect; air cleaning; particle source; modelling; intermediate filter; filter standard;

    Abstract : Epidemiological and toxicological studies demonstrate that ultrafine particles (UFPs) are strongly related with respiratory and cardiovascular diseases and syndromes. One common method to reduce human exposure to particulate air pollution is the use of intermediate class filters (F5-F9 class filters according to EN779:2002). READ MORE

  7. 20. Modelling as a Tool to Evaluate Continuously Measured Concentration Value of Gaseous Indoor Air Pollutants

    Author : Martin Kraenzmer; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NO2; modeling; TVOC; modelling; indoor air; pollutants; continuous monitoring; NOx; VOC; NO; O3; continuous measurement; CO; CO2;

    Abstract : Results from studies of air quality in buildings are often difficult to interpret and evaluate and, in order to avoid erroneous conclusions, special evaluating tools may be needed. Modelling in various forms can be used as a method of evaluating measured values from such investigations. READ MORE
