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

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

    Sammanfattning : 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.

    Sammanfattning : 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. LÄS MER

  4. 3. Determination and control of some pollutants in indoor environments

    Författare :Pawel Markowicz; Avdelningen för medicinsk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; indoor air quality; indoor pollutants; dampness; purification; tobacco smoke;

    Sammanfattning : Unsatisfactory indoor air quality (IAQ) may result from polluting emissions that are spread from building materials such as volatile organic compounds (VOCs) and/or microbial components or from various kinds of human activity such as smoking. Different methods are available to limit the exposure to unwanted pollutants and improve human wellbeing and health. LÄS MER

  5. 4. Air diffusion and solid contaminant behaviour in room ventilation : a CFD based integrated approach

    Författare :Gery Einberg; Sture Holmberg; hazim Awbi; KTH; []
    Nyckelord :Technology; CFD modelling; airflow rate; ventilation efficiency; diffusers; solid contaminants; IAQ; TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : One of the most fundamental human needs is fresh air. It has been estimated that people spend comparatively much time in indoor premises. That creates an elevated need for high-quality ventilation systems in buildings. The ventilation airflow rate is recognised as the main parameter for measuring the indoor air quality. LÄS MER

  7. 5. Impact of Radon Ventilation on Indoor Air Quality and Building Energy saving

    Författare :Keramatollah Akbari; Jafar Mahmoudi; Öman Robert; Sylvia Waara; Jan Akander; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mechanical energy engineering; Mekanisk energiteknik; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : Industrial living is caused much people do live and work in closed and confined places; offices and residential buildings. This is why in this new world more fresh air which is generally provided by forced ventilation plays a vital role in living of human being. LÄS MER
