  5. 5. Performance-based design of ventilation systems. Potential and limitations regarding indoor air quality

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Ragib Kadribegovic; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ventilation; prescriptive design; indoor air quality; air cleaning; energy efficiency; performance-based design; recirculation;

    Abstract : It has been increasingly common to design for increased ventilation rates above legislative requirements specified in building codes and other norms as the most optimum way to improve indoor air quality. However, this concept has recently been challenged, for example, by studies demonstrating that the emissions or pollution from used traditional particle filters increases proportionally with air flow through the filter.
