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

    University essay from Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

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

    Abstract : 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. READ MORE

  3. 2. Development of Radon Detectors for Earthquake Prediction

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Alma Partos; Astrid Schöldström; [2023]
    Keywords : Radon; earthquake; gamma ray spectroscopy;

    Abstract : The purpose of this project is to simulate the detection of γ-ray spectra emitted by radon isotopes and their daughters. This is done as a contribution to the development of radiation detectors to be used in a research project investigating the possibility of using increased amounts of the radioactive gas radon as an earthquake precursor.

  4. 3. Sustainable management of the African elephant – stakeholder solutions to a human-wildlife conflict

    University essay from SLU/Dept. of Anatomy, Physiology and Biochemistry

    Author : Varwi Jacob Tavaziva; [2023]
    Keywords : sustainability; hunting; stakeholders; meat; bees; chillies;

    Abstract : Densities of African elephants have increased in southern Africa, reaching a population size of 45000 in some protected areas such as Hwange National Park, which is beyond the estimated carrying capacity of 15000. The overpopulation of elephants at Hwange National Park has stimulated considerable debates among stakeholders about the effective and sustainable approach to managing elephants. READ MORE

  5. 4. Environmental sustainability of a low-temperature heating system : A case study

    University essay from KTH/Byggteknik och design

    Author : Bogdan Kurasov; Ahmed Alchasov; [2023]
    Keywords : ;

    Abstract : Nowadays, 40% of annual global CO2-emission is caused by the building sector. 27% of these emissions are coming from building operations and the main use of energy in buildings is heating. READ MORE

  6. 5. Free cooling and PVT integration in a ground-source heat pump (GSHP) system

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Christopher Pourier; [2023]
    Keywords : Ground-source heat pump; borehole; GSHP; photovoltaic thermal collector; PVT; free cooling; Ytjordvärmepump; borrhål; GSHP; solfångare; PVT; frikylning;

    Abstract : The performance of ground-source heat pump (GSHP) systems can be negatively affected over time by soil temperature degradation of boreholes (BH) in heating dominated climates. Land area is scarce in the dense urban environments typical of multi-family houses (MFH) and can lead to accelerated degradation- in tight BH fields. READ MORE
