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

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

    Abstract : 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. READ MORE

  4. 2. Experimental study of an intermittent ventilation system in high occupancy spaces

    Author : Alan Kabanshi; Patrik Sörqvist; Hans Wigö; Robert Ljung; Hazim Awbi; Högskolan i Gävle; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Intermittent airflow; Indoor air quality; Perceived air quality; Thermal sensation; thermal comfort; Air movement acceptability; Convective cooling; Cooling effect.; Intermittent luftflöde; Luftstrålar; Upplevd luftkvalitet; Termisk komfort; Acceptans av luftrörelser; Konvektiv kylning; Kyleffekt.; Hållbar stadsutveckling; Sustainable Urban Development;

    Abstract : Spaces with high occupancy density like classrooms are challenging to ventilate and use a lot of energy to maintain comfort. Usually, a compromise is made between low energy use and good Indoor Environmental Quality (IEQ), of which poor IEQ has consequences for occupants’ health, productivity and comfort. READ MORE

  5. 3. Multi-dimensional approach used for energy and indoor climate evaluation applied to a low-energy building

    Author : Fredrik Karlsson; Bahram Moshfegh; Hazim Awbi; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low-energy building; energy; indoor climate; simulation; Lågenergihus; energi; inomhusklimat; simulering; Building engineering; Byggnadsteknik;

    Abstract : The building sector alone accounts for almost 40% of the total energy demand and people spend more than 80% of their time indoors. Reducing energy demand in buildings is essential to the achievement of a sustainable built environment. At the same time, it is important to not deteriorate people’s health, well-being and comfort in buildings. READ MORE

  6. 4. Energy efficiency and ventilation in Swedish industries barriers, simulation and control strategy

    Author : Patrik Rohdin; Bahram Moshfegh; Hazim Awbi; Magnus Karlsson; Alfred Moser; Linköpings universitet; []
    Keywords : Industrial energy efficiency; Industrial ventilation; Barriers; Driving forces. CFD; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The energy issue is presently in focus worldwide. This is not only due to increasing environmental concern regarding energy related emissions, but also due to the trend of increasing energy prices. Energy usage in the industrial sector in Sweden today represents about one third of the national energy use. READ MORE
