  1. 1. Analys av klimatpåverkan från ventilationssystem vad avser utformning och systemval i kontorsbyggnad

    Kandidat-uppsats, Lunds universitet/Avdelningen för Installations- och klimatiseringslära

    Författare :Ada Kajtaz; Sarah Abuayyash; [2024]
    Nyckelord :Climate analysis; ventilation system; carbon emissions; sustainability; environmental impact; material optimization.; Technology and Engineering;

    Sammanfattning : Bakgrund: Byggsektorn står för en väsentlig del av Sveriges växthusgasutsläpp, motsvarande 21% enligt Boverket. För att nå Sveriges klimatmål med minst 85% minskning av nettoutsläppen till 2045 krävs hållbara byggnader och installationsdesign, särskilt inom ventilation och komfortkyla. LÄS MER

    Sammanfattning : Introduction: Additive manufacturing (AT) also known as 3D printing has become a more widespread technology in various industries. The manufacturing method has increased the efficiency of manufacturing industries in producing products with technically challenging properties. LÄS MER

  4. 3. Predicting room occupancy based on carbon dioxide concentration levels : And potential energy-saving use cases in HVAC (heating, ventilation and air conditioning) control systems.

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Elias Eliasson Schuhmacher; Markus Ledung; [2023]
    Nyckelord :;

    Sammanfattning : This thesis aims to explore the possibilities of recording room occupancy based on measured CO2 (carbon dioxide) concentration levels, and potential energy-saving uses in HVAC (heating, ventilation and air conditioning) - control systems. Furthermore, this thesis specifically aims to use unsupervised machine learning methods, which removes the need for generating correct occupancy labels and training the models before deploying them.

  5. 4. Lowering energy need and improving indoor climate - A case study of rural dwellings in Gammalsvenskby, Ukraine

    Master-uppsats, Lunds universitet/Institutionen för arkitektur och byggd miljö; Lunds universitet/Avdelningen för Energi och byggnadsdesign

    Författare :Viktor Kauranen; [2022]
    Nyckelord :Gammalsvenskby; energy-efficient; indoor climate; rural buildings; renovation; Ukraine; Life cycle cost; Technology and Engineering;

    Sammanfattning : A vast majority of rural dwellings in Ukraine are inefficient from an energy perspective, with a major need for energy-efficient renovations. A lot of these buildings are also having problems with the indoor climate, with poor ventilation combined with indoor combustion of fuel which can cause negative health effects. LÄS MER

  7. 5. Predicting Indoor Carbon Dioxide Concentration using Online Machine Learning : Adaptive ventilation control for exhibition halls

    Master-uppsats, Jönköping University/Tekniska Högskolan

    Författare :Filip Carlsson; Edvin Egerhag; [2022]
    Nyckelord :CO2 Prediction; CO2 Concentration; Exhibition Halls; Online Machine Learning; Machine Learning; Streaming Data;

    Sammanfattning : A problem that exhibition halls have is the balance between having good indoor air quality andminimizing energy waste due to the naturally slow decrease of CO2 concentration, which causes Heat-ing, Ventilation and Air-Conditioning systems to keep ventilating empty halls when occupants have leftthe vicinity. Several studies have been made on the topic of CO2 prediction and occupancy predictionbased on CO2 for smaller spaces such as offices and schools. LÄS MER
