  1. 1. Optimering av klassrumsmiljön i en ny skolbyggnad i Västerås : En studie om fönsterplacering och energiförluster

    Uppsats för yrkesexamina på grundnivå, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Författare :Kunda Fadi; Alhamada Nahla; Celen Mert; [2023]
    Nyckelord :School; design; window; window design; daylight; u-value; thermal bridges; heat losses; energy losses; energy saving.;

    Sammanfattning : Purpose: The purpose of this study was to plan blueprints for a school located Härbregatan and Vallby Skolgata in Västerås with a focus on energy losses and window placement to choose the most suitable types of windows to obtain a good internal environment. Method: The methodology used to conduct this thesis was based on earlier case studies, literature book and literature reviews in the form of legal specification from Boverket Byggregel (BBR) that had a significant impact on how the school was designed, interior and exterior views.

  3. 2. Using Dynamic Double Machine Learning for Guided District Heating Forecasting and Physical Parameter Extraction

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Justinas Smertinas; [2022]
    Nyckelord :Double Machine Learning; Time Series; District Heating; ARMAX; Forecasting; Solar Gain; Diurnal Effects; Mathematics and Statistics;

    Sammanfattning : This thesis’ main goals were to provide accurate forecasts and informative physical parameter estimates for energy use of the district heating in the Tingbjerg neighborhood, Copenhagen. Our work is aimed as a contribution for future work towards efficient on-demand energy production. LÄS MER

  4. 3. Damage Criteria for Fibre Optic Cables Exposed to Fire - Using data transfer as functional criterium

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Joakim Åström; Sofia Lindahl; [2021]
    Nyckelord :Cable; fibre optic cables; data transfer; data loss; functional criterium; damage criteria; bend diameter; temperature; fire conditions; heat flux; cone calorimeter; probabilistic distribution; risk analysis; Technology and Engineering;

    Sammanfattning : The aim of this master thesis was to analyse the possibility to use fibre optic cables for critical safety features in high reliability facilities. In more detail, this report investigates how transferred data in fibre optic cables are affected by fire and if there is any risk that the data becomes corrupted or lost when exposed to fire conditions.

  5. 4. Värmeförluster och energibesparing till följd av bassängtäckning för utomhusbassänger : Heat losses and energy savings due to pool coverage for outdoor pools

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

    Författare :Mark Shafti; [2021]
    Nyckelord :Bassängtäckning;

    Sammanfattning : Sammanfattning I Sverige finns det cirka 450 offentliga badanläggningar varav flera av dem har utomhusbassänger med hög energiförbrukning. Energiförbrukningen är i genomsnitt 403 kWh per m² bassängarea, år. LÄS MER

  7. 5. Brandfarliga vätskor i syrereducerade miljöer

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Carl Nilsson; Max Hersner; [2021]
    Nyckelord :Hypoxic air; Brandfarliga vätskor; Reduced oxygen; Limiting oxygen; Cone calorimeter; Flammable liquids; ORS; LOC; CACC; Heat release rate; Mass loss rate; Technology and Engineering;

    Sammanfattning : Unmanned warehouses are increasing in number as workers are replaced by automated robotic systems. This type of facility, among others, is well suited for an oxygen reduction system for fire protection. By lowering the oxygen concentration, the risk of fire propagation is reduced and might be hindered altogether. LÄS MER
