2. 1. 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

4. 2. The indoor environment in schools : Respiratory effects and air quality

   Author : Greta Smedje; Uppsala universitet; []
   Keywords : Medical sciences; Allergy; asthma; cat allergen; cleaning; dust; formaldehyde; furniture; mould; schoolchildren; ventilation; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; arbets- och miljömedicin; Occupational and Environmental Medicine;

   Abstract : The main objective of this work was to investigate relationships between the schoolenvironment and asthma and asthmatic symptoms in schoolchildren. Data on symptoms werecollected through postal questionnaires answered by 1,732 pupils in 39 randomly selectedschools, and were related to data on exposures obtained through hygienic measurements in theschools.

5. 3. Ultrafine Particles in Indoor Air. Measurements and modelling

   Author : Uve Matson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; airborne particles; aerosols; ventilation; air quality; outdoor air;

   Abstract : Clean air is one of the most fundamental human needs. Since people spen on average over 85% of their time indoors at work, home, school etc., human exposure to air pollution may mostly occur indoors. READ MORE

6. 4. Ultrafine Particles in the Indoor Environment: Field and Laboratory Measurements

   Author : Uve Matson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; airborne particles; aerosols; indoor air; outdoor air; air quality;

   Abstract : Clean air is one of the most fundamental human needs since poor air quality affects the health and the environment. It has been shown that people spend on average over 85 % of their time at work, home, school etc. Therefore, human exposure to air pollution may occur mostly indoors. Despite this fact, outdoor air pollution is also important. READ MORE

7. 5. Natural Ventilation and Air Infiltration in Large Single‑Zone Buildings : Measurements and Modelling with Reference to Historical Churches

   Author : Abolfazl Hayati; Magnus Mattsson; Mats Sandberg; Jens Fransson; Guilherme Carrilho da Graça; Högskolan i Gävle; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Natural ventilation; Airing; Air infiltration; Single-sided ventilation; Cross flow; Large single zones; Historical Churches; Model evaluation optimization; Field measurements; Wind tunnel; Indoor climate and Energy simulation; IDA-ICE; Tracer gas technique; Pressurization test.; Naturlig ventilation; Vädring; Luftinfiltration; Ensidig ventilation; Tvärdrag; Höga en-zonsbyggnader; Kulturhistoriska kyrkor; Modellutvärdering optimering; Fältmätningar; Vindtunnel; Inomhusklimat och energisimulering; IDA-ICE; Spårgas teknik; Trycksättningstest.; Hållbar stadsutveckling; Sustainable Urban Development;

   Abstract : Natural ventilation is the dominating ventilation process in ancient buildings like churches, and also in most domestic buildings in Sweden and in the rest of the world. These buildings are naturally ventilated via air infiltration and airing. READ MORE
