  1. 21. Solar access potential affected by urban planning and building design – A parametric study in the urban context

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

    Författare :Yuncong Li; Yiting Tian; [2020]
    Nyckelord :Daylight; urban planning; solar access potential; sun hours; vertical sky component; vertical daylight illuminance; solar irradiation; parametric analysis; Berlin; Copenhagen; Hong Kong; Arts and Architecture; Technology and Engineering;

    Sammanfattning : In the initial stage of planning, considering the solar impact of urban layout on the building can effectively avoid some irreversible design issues, improve the indoor environment, and reduce energy demand. The typical architectural models of three representative cities (Copenhagen, Berlin and Hong Kong) were selected as the analysis cases in this study. LÄS MER

  3. 22. Pre-feasibility study of V2G system in the micro-grid of St. Martine Island, Bangladesh.

    Magister-uppsats, Uppsala universitet/Elektricitetslära

    Författare :Md Abu Raihan Chowdhury; [2020]
    Nyckelord :Vehicle to grid; Micro-grid; Electric Vehicle; Simulink Simscape; Feasibility analysis.;

    Sammanfattning : The goal of the study was to evaluate the potential of the V2G system as a solution to peak load leveling and integrating more renewable energy in the microgrid of St. Martine Island. Simulink Simscape software was used to model a microgrid with a V2G system for the small community of the Island. LÄS MER

  4. 23. Feasibility Study of Chemical Energy Storage for an Energy Efficient Commercial Office Space

    Magister-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Kerry-Leigh Maritz; [2019]
    Nyckelord :“Chemical Energy Storage”; “Commercial”; “Energy Storage”; “Load Demand Shift”; “50kW Solar System”;

    Sammanfattning : Shifting the load demand of a commercial office space to utilise off peak tariffs would lead to cost savings as power is cheaper at this time. To achieve this shift, chemical energy storage was considered using Lead Acid batteries, Lithium-ion batteries and Advance Lead Acid batteries. The output of these storage types is electricity.

  5. 24. Bee wax moth in Embu county, Kenya, the intruder in the hives : a study of Galleria mellonella and Achroia grisella

    Kandidat-uppsats, SLU/Dept. of Ecology

    Författare :Sanna Bergqvist; [2019]
    Nyckelord :bee wax moth; African bees; prevention; control;

    Sammanfattning : The bee wax moth is a problematic pest that has been a problem to Kenyan bee farmers for some time now. This study has tried to answer if the observed factors affected the infestation rate of the pest. LÄS MER

  7. 25. Elbil utan elnät - Utnyttjandet av omgivning och klimat för etablering av elbil

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Viktor Tähtinen Dahl; [2019]
    Nyckelord :;

    Sammanfattning : Några av de mest ogästvänliga och otillgängliga platser på jorden kan anses olämpliga för dagens elfordon då räckviddsångest är en verklighet i länder med ett välutvecklat elnät exempelvis Sverige. Bland dessa ogästvänliga platser tillhör bland annat de afrikanska ökenområdena, den Australienska outbacken samt den sibiriska tundran. LÄS MER
