  1. 1. Monitoring air quality indicators and energy consumption in Dalarnas Villa during operation of a demand-controlled exhaust ventilation system

    University essay from Högskolan Dalarna/Energiteknik

    Author : Ian Garman; Ahmad Haj Ahmad; [2020]
    Keywords : Ventilation; demand control; airflow; frånluft; exhaust; carbon dioxide; CO2; indoor air quality; IAQ; air monitoring; villa; single family house; småhus; energy efficiency;

    Abstract : A real-world study was undertaken of the indoor air quality in a recently-built single family home in central Sweden, to establish whether demand controlled ventilation provided superior interior conditions, when compared with other air supply strategies, including the standard used by the Swedish buildings regulator. The property was highly airtight, with ventilation achieved using a forced exhaust system. READ MORE

  2. 2. Indoor Air Pollution, Passive Ventilation Strategies and Thermal Comfort in Nepal

    University essay from Lunds universitet/Institutionen för arkitektur och byggd miljö

    Author : Marianne Löwgren; [2019]
    Keywords : Energy poverty; Solid biomass fuels; Improved cooking stoves; Indoor air pollution; Carbon monoxide; Vernacular architecture; Passive ventilation; Air exchange rate; Indoor air quality; Thermal comfort; Operative temperature; Sustainable societal development; Social Sciences; Technology and Engineering;

    Abstract : Indoor Air Pollution (IAP) resulting from indoor burning of solid biomass fuels in poorly ventilated kitchens is a severe health risk in parts of the world where energy poverty is prevalent. Passive ventilation, i.e. taking advantage of naturally induced airflow has been suggested as crucial in reducing IAP levels below safe limits. READ MORE

  3. 3. Modeling and Optimization of Energy Utilization of Air Ventilation System of an Auditorium

    University essay from Högskolan i Gävle/Energisystem

    Author : Kappina Kasturige Kamani Sylva; [2016]
    Keywords : Hybrid Ventilation; CFD modeling; Auditorium;

    Abstract : Maintaining IAQ (Internal Air Quality) and thermal comfort of occupants in buildings have been a challenge to overcome satisfying the two ends: criteria for sustainability and cost effectiveness. Although there was a movement for mechanical ventilation systems in the recent past, in addition to the cost involved, they are found to not deliver the desired air quality, lead to social consequences such as sick building syndrome, contribute to environmental consequences related to ozone-depleting substances with increasing energy consumption, generate noise and having difficulties in cleaning and maintaining.
