  1. 1. Fönsterareans klimatpåverkan : Jämförelse av koldioxidutsläpp från material- och energianvändning när fönsterarea varieras

    M1-uppsats, Karlstads universitet/Avdelningen för energi-, miljö- och byggteknik

    Författare :Philip Möller; Erik Elfstrand; [2023]
    Nyckelord :;

    Sammanfattning : Right now, the world is facing a challenge of reducing carbon emissions. Existing buildings account for one-third of the world's carbon emissions. The construction and real estate sector in Sweden is facing the challenge of combining a high rate of construction with demands on reduced climate emissions. LÄS MER

  3. 2. Techno-economic analysis and simulation of low temperature district heating networks

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

    Författare :Ilia Iarkov; [2023]
    Nyckelord :Low-temperature district heating; Modelica; BTES; LCA; LCC; Technology and Engineering;

    Sammanfattning : The continuous increase in global energy consumption has led to a greater focus on the energy required for heating buildings. This thesis presents a techno-economic model for analysing low-temperature district heating networks coupled with a geothermal heat source. LÄS MER

  4. 3. Commercialization of a Niche Sustainable Microwave AI Technology Innovation : A case study in Percy Roc AB

    Master-uppsats, Uppsala universitet/Industriell teknik

    Författare :Aynaz Mirzazada; Jerry Faisal; [2023]
    Nyckelord :Energy Costs; Industrial Heating; Microwave AI Heating Technology; Commercialization of Niche Technological Innovations; Sustainable Heating Technologies;

    Sammanfattning : Nowadays, increasing energy costs create challenges for societies. In industries such as manufacturing, energy is one of the basic needs for development, automation, and modernization. The increase in energy costs affects economic growth, especially, in the manufacturing industry which depends on the energy consumption to run their facilities. LÄS MER

  5. 4. Analys och minskning av effektförlusterna i en borstlös likströmsmotor med vektorstyrning

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Lider Xavier Garcia Parrales; [2023]
    Nyckelord :Effektförluster Borstlös likströmsmotor BLDC Vectorstyrning Field-oriented Control FOC Blockkommutering Block commutation MTPA; Technology and Engineering;

    Sammanfattning : This report addresses power losses in an electric motor arising from various sources. The choice of motor control strategy can decrease efficiency if not implemented correctly or if the motor model in the control loop is overly simplified. LÄS MER

  7. 5. Using a GIS to enable an economic, land use and energy output comparison between small wind powered turbines and large-scale wind farms: the case of Oslo, Norway.

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Colin Potter; [2023]
    Nyckelord :Geography; GIS; Wind power; Renewable energy sources; urban wind energy; urban areas; planning; vertical axis wind turbines; comparative studies; urban integrated energy systems; Oslo; Roan; Earth and Environmental Sciences;

    Sammanfattning : Responding to an identified knowledge gap, the study aims to determine if smaller wind turbines located on top of existing urban buildings are more resource efficient (land utilization and economically) than large scale wind farms. To answer this question, using a GIS, the resource efficiency of the Roan wind farm in Northern Norway was compared to a theoretical modeled installation of small-scale wind turbines on top of buildings within a 2km radius study zone in central Oslo.
