  2. 6. Indoor air quality and chemical emissions of organic compounds in newly built low-energy preschools

    Author : Josefin Persson; Thanh Wang; Jessika Hagberg; Pim Leonards; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Indoor air quality; volatile organic compounds; brominated flame retardants; organophosphate flame retardants; low-energy preschools; environmental certification; indoor dust; surface wipes;

    Abstract : In 2010, the European Union (EU) introduced the “Energy performance of Buildings” directive, which stipulates that all new buildings must reduce their energy consumption by constructing low-energy buildings. This could be achieved by constructing airtight and energy efficient envelopes with functional building materials such as age-resistant plastic films, insulation and different sealing products.

    Abstract : Indoor air quality directly affects the comfort, performance, and well-being of occupants. Indoor pollution can cause immediate or long-term health effects and has been responsible for 4.1% of global deaths in recent decades. READ MORE

  5. 8. Chemical emissions from building structures : emission sources and their impact on indoor air

    Author : Annika Glader; Ingrid Liljelind; Berndt Stenberg; Umeå universitet; []

    Abstract : Chemical compounds in indoor air can adversely affect our comfort and health. However, in most cases there is only a limited amount of information available that can be used to assess their health risk. Instead the precautionary principle is often applied, i.e. READ MORE

  6. 9. Influence of building envelope on indoor air quality: Field measurements, analysis, and method development related to indoor odors

    Author : Fredrik Domhagen; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; material emissions; VOC; odor; ventilation; indoor air quality;

    Abstract : The ventilation system should provide occupants with fresh air while removing excess pollutants from the building. However, increasing ventilation may inadvertently draw more pollutants into the occupant area or prove ineffective in altering emission rates from building materials and furnishings. READ MORE

  7. 10. A Sociological Approach to Indoor Environment in Dwellings : Risk factors for Sick Building Syndrome (SBS) and Discomfort

    Author : Karin Engvall; Dan Norbäck; Eva Sandstedt; Göran Strid; Uppsala universitet; []

    Abstract : The principal aim was to study selected aspects of indoor environment in dwellings and their association with symptoms compatible with the sick building syndrome (SBS). A validated questionnaire was developed specifically for residential indoor investigations, using sociological principles and test procedures. READ MORE
