    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Josefine Nilsson Willkomm; [2020]
    Nyckelord :life cycle assessment; ventilation system; environmental impact; hybrid ventilation system; mechanical ventilation system with heat recovery; livscykelanalys; ventilationssystem; miljöpåverkan; ventilation; hybrid ventilationssystem; mekaniskt ventilationssystem med värmeåtervinning;

    Sammanfattning : The building sector is responsible for 36% of the energy usage and 39 % of all CO2- emissions in European union (EU). Therefore, it is of great interest to investigate how the building sector can become more energy efficient and lower the environmental impact. LÄS MER

  3. 52. Verkliga fiktiva linjer : en studie av olika kartor

    Kandidat-uppsats, SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Författare :Hanna Vilde Hörnell; [2020]
    Nyckelord :karta; kartor; isokronkarta; koropletkarta; geografisk information; kognitiv karta; linjekarta;

    Sammanfattning : Det här arbetet handlar om kartor: vad de består av, hur människors upplevelser av landskapet kan återges i kartor och vad de kan användas till inom landskapsarkitekturen. Arbetet kommer att behandla ett par specifika karttyper: isokronkartor, isogröna kartor, koropletkartor, densitetsutjämnande kartor, en vinklad perspektivkarta, iknografiska kartor och kognitiva kartor.

  5. 54. 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

  7. 55. Development of a GC Method for the Quantification of Short Chain Carboxylic Acids in Aqueous Solution

    Sammanfattning : Petroleum powered vehicles emit volatile organic compounds (VOCs) through combustion that contributes to the pollution of the environment. A technique in the 1970s was developed to decrease these emissions, especially for nitrogen oxides (NOx) and sulphuric oxides (SOx) which is called exhaust gas recirculation (EGR). LÄS MER
