  1. 1. Study of optimization of two projects in "Million Program" areas : - a sustainable point of view in a suburb to a big city and a suburb to a small town

    Kandidat-uppsats, KTH/Byggteknik och design

    Författare :Isac Mihlté; Jonatan Leander; [2021]
    Nyckelord :substaiability; Million program; renovation; economic; social; ecological; hållbarhet; miljonprogram; renovering; socialt; ekologiskt; ekonomiskt;

    Sammanfattning : The renovation and maintenance projects in the “Million program” areas are currently ongoing in many parts of the country. As the stocks in many descriptions have similar conditions with regard to urban structure, construction technology and socio-economic situation, there is great potential for comparison. LÄS MER

  3. 2. El-och värmeenergibehov för skolor : Beräknade och uppmätta värden för 4 skolor i Stockholm

    Master-uppsats, Karlstads universitet

    Författare :Hedda Andersson; [2021]
    Nyckelord :;

    Sammanfattning : As buildings are built more and more energy-efficient, precision of energy calculations needs to increase as the error decrease and the requirement to calculate “correctly” increases. At the beginning of a construction project, a builder must show that the building will comply with the National Board of Housing, Building and Planning's regulations when the project is completed in order to start the project.

  4. 3. Systemlösningar för energieffektivisering av storköksventilation : Kortslutningskåpans potential och begränsningar

    Kandidat-uppsats, Högskolan Dalarna/Energiteknik

    Författare :Morgan Wilhelmsson; [2020]
    Nyckelord :Commercial kitchen ventilation; Short circuit hood; Energy efficiency; Heat recovery; Storköksventilation; Kortslutningskåpa; Uteluftskåpa; Energieffektivisering; Värmeåtervinning;

    Sammanfattning : Studien syftar till att undersöka teorin bakom kortslutningskåpan, dess potential och begränsningar. Undersökningen inleds med en litteraturstudie vilken följs av en fallstudie där ett system med kortslutningskåpa, med avseende på energibehov och systemkostnad, jämförs med ett system med en vanlig kåpa respektive ett system med värmeåtervinning.

  5. 4. 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. 5. KEY FACTORS AND PROBLEMS IN THE PERFORMANCE OF KITCHEN VENTILATION SYSTEMS

    Magister-uppsats, Högskolan i Gävle/Avdelningen för byggnadsteknik, energisystem och miljövetenskap

    Författare :ÁLVARO ROS; [2020]
    Nyckelord :RESTAURANT KITCHEN VENTILATION; KITCHEN HOOD; VENTILATION SYSTEM; AIRFLOW; AIR QUALITY; PRESSURE DROP; HOOD PERFORMANCE; EFFICIENCY;

    Sammanfattning : Regarding the great importance of a good working environment, in this research, ventilation systems installed in kitchens of restaurants were studied in order to avoid problems and to understand the key factors that can influence on the performance of the system. The results obtained were taken into account to provide some recommendations to a real ventilation system of a restaurant called Pastaria in Gävle (Sweden). LÄS MER
