  1. 1. Technical performance modelling and optimization of PVT collectors in GSHP integration

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Marin Courcault; [2023]
    Nyckelord :PVT; ISO9806:2017; mass flow; use conditions; test conditions; coefficients optimization; TRNSYS; PVT; ISO9806:2017; massflöde; användningsförhållanden; testförhållanden; optimering av koefficienter; TRNSYS;

    Sammanfattning : In order to contribute to reducing the CO2 emissions related to heating in housing buildings, PVT+GSHP systems appear to be interesting solutions and therefore need to be further investigated to optimise their design and increase their deployment on the field. This thesis focused on building PVT model, using the ISO9806:2017, to be integrated in a PVT+GSHP model and determining optimal PVT design parameters for this system. LÄS MER

  3. 2. A Bayesian Bee Colony Algorithm for Hyperparameter Tuning of Stochastic SNNs : A design, development, and proposal of a stochastic spiking neural network and associated tuner

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Oskar Falkeström; [2023]
    Nyckelord :edge computing; edge user allocation; constraint satisfaction problem; bin packing problem; spiking neural networks; SNN; stochastic spiking neural networks; neuromorphic computing; hyperparameter tuning; swarm intellience; artificial bee colony algorithm; tree-structured Parzen estimator; stochastic optimization; Bayesian optimization.;

    Sammanfattning : With the world experiencing a rapid increase in the number of cloud devices, continuing to ensure high-quality connections requires a reimagining of cloud. One proponent, edge computing, consists of many distributed and close-to-consumer edge servers that are hired by the service providers. LÄS MER

  4. 3. Skiljer sig energiberäkningarna i projekteringsstadiet från energiberäkningarna i relationshandlingarna?

    Uppsats för yrkesexamina på grundnivå, Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Författare :Ellen Ingarsson; Ellen Sköld; [2022]
    Nyckelord :Energy performance; energy use; design stage; production stage; space heating; heat loss coefficient; hot water recirculation; FTX-ventilation; fan energy; Total energianvändning; programhandling; relationshandling; uppvärmning; Umedel; varmvattencirkulation; FTX-system; fläktel;

    Sammanfattning : To reduce the emissions from energy use, high demands are set on new buildings. Studies have shown big differences between predicted and actual energy performance. This gap makes it more difficult to reduce the energy use in buildings. LÄS MER

  5. 4. An evaluation of the influential factors on energy performance: A case study of a shopping mall

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

    Författare :Maryam Rabitabar; [2022]
    Nyckelord :Energy; building performance; relations; measured data; data analysis; Pearson Correlation Coefficient; statistical method; HVAC systems; complex building; shopping malls; Technology and Engineering;

    Sammanfattning : Shopping malls are becoming more prevalent throughout the world. They have been identified as having high energy use, which is less explored than other building types. There are 357 shopping centers in Sweden, which has doubled in the last five years. LÄS MER

  7. 5. Computational Design in the AEC industry : Applications and Limitations

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Rasmus Mikaelsson; [2022]
    Nyckelord :Parametric design; generative design; design automation; design exploration; architectural engineering construction;

    Sammanfattning : The AEC-industry need to respond to multiple requirements from regulations and clients, leading to that building projects are becoming increasingly complex to handle for designers. CAD or computer aided design is a way to handle these challenges, and within CAD a new method is emerging: Computational design enables users to generate and explore design solutions automatically.
