   Sammanfattning : Nowadays individuals spend more than 85% of their total time in indoor environments, mainly at home and work. Thereby, the quality of the indoor environment plays a substantial role in human health and wellness. LÄS MER

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

   Magister-uppsats, Högskolan Dalarna/Energiteknik

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

   Sammanfattning : 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. LÄS MER

4. 38. A Study of Smart Ventilation System to Balance Indoor Air Quality and Energy Consumption : A case study on Dalarnas Villa

   Master-uppsats, Högskolan Dalarna/Mikrodataanalys

   Nyckelord :Smart ventilation; Demand-controlled ventilation; Fan energy use; Indoor air quality; Residents living patterns; Indoor CO2 prediction; Ventilation modes; Clustering analysis; Correlation analysis; Regression analysis; Sensor data;

   Sammanfattning : It is a dilemma problem to achieve both these two goals: a) to maintain a best indoor air quality and b) to use a most efficient energy for a house at the same time. One of the outstanding components involving these goals is a smart ventilation system in the house. LÄS MER

5. 39. Indoor and Outdoor Measurements of Particulate Matter with the Low-Cost Optical Sensor OPC-N3

   Kandidat-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

   Författare :Ellen Grace Soroka; [2020]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : This paper evaluates the low-cost optical sensor OPC-N3 from Alphasense as a suitable scientific instrument for measuring particulate matter levels in air, both outdoors and in- doors. The time-keeping and data-retrieval was additionally improved by connecting the OPC-N3 to an Arduino microcontroller equipped with a real-time clock (RTC) module and an external SD card. LÄS MER

7. 40. Household air pollution exposure in sub-Saharan Africa and assessment of disease burden attributable to risk factor
