1. Svenska gymnasieelevers uppfattningar om storlek och avstånd i universum
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Fysiska institutionen; Lunds universitet/Institutionen för utbildningsvetenskapSammanfattning : This study aims to investigate how students in Swedish upper secondary school conceptualize sizes and distances of some astronomical objects, such as planets and stars, as well as the students’ general knowledge of the objects themselves. The study uses a constructivist framework and explores how well the students’ conceptions match the scientific facts and definitions, and what misconceptions and alternative conceptions they hold.

2. Monitoring air quality indicators and energy consumption in Dalarnas Villa during operation of a demand-controlled exhaust ventilation system
Magister-uppsats, Högskolan Dalarna/EnergiteknikSammanfattning : 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
3. Indoor Air Pollution, Passive Ventilation Strategies and Thermal Comfort in Nepal
Master-uppsats, Lunds universitet/Institutionen för arkitektur och byggd miljöSammanfattning : 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. LÄS MER
4. Modeling and Optimization of Energy Utilization of Air Ventilation System of an Auditorium
Master-uppsats, Högskolan i Gävle/EnergisystemSammanfattning : 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.

5. Health Risks of VOCs and Aldehydes in Indoor Air : A Case Study of Three Beauty Salons and a Gym
Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknikSammanfattning : People tend to spend more and more time indoors, constantly breathing indoor air. In indoor air there is a mixture of chemicals from both the outdoor air, which is let in through the ventilation systems, and from the materials and products that are used indoors. LÄS MER
