  2. 21. Novel and ancient technologies for heating and cooling buildings

    Author : Sofiane Amara; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Abstract : The basic issue of this thesis concerns one of the fundamental problems of the future of our society: How to meet the energy requirements for a large and growing world population while preserving our environment? This question is important for the world and the answers are complex and interwoven.Conventional energy sources, fossil and fissile, are polluting in the present and in the future: they erode the environment and their resources are limited.

  4. 22. Overcoming inertia to sustainable stormwater management practice

    Author : Annicka Cettner; Sarah Bell; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Abstract : In Sweden, there is a growing receptivity for change to more sustainable stormwater practices using green infrastructure approaches. Unlike piped drainage systems they can have multiple benefits in use including flood control, pollutant removal and can add to the quality of urban space supporting green infrastructure through irrigation and providing cooling and an additional water source for supply.

  5. 23. Climate and geographical influence on the performance of infiltration-based facilities for managing runoff – Temporal and spatial variability

    Author : Ivan Mantilla; Maria Viklander; Tone Merete Muthanna; Kelsey Flanagan; Vegard Nielsen; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Green infrastructure; hydrological performance; infiltration capacity; climatic pattern; saturated hydraulic conductivity; VA-teknik; Urban Water Engineering;

    Abstract : Climate change is expected to lead to more intense and severe rainfall events in the future, significantly increasing the risk of urban flooding. This change, characterized by spatial and temporal shifts in precipitation patterns, presents a challenge to the capacity of existing urban drainage systems, which may lead to higher runoff volumes than they were initially designed to handle.

  6. 24. Performance of on-site systems and a green wall for greywater treatment

    Author : Mashreki Sami; Annelie Hedström; Elisabeth Kvarnström; Inga Herrmann; Sahar Dalameh; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Abstract : Greywater contains inorganic and organic substances, nutrients, pathogens, micropollutants and microplastics. Source-separated greywater using decentralized systems can potentially provide energy-efficient and low-maintenance treatment. READ MORE

  7. 25. Agricultural expansion impacts on wetland ecosystem services from Kilombero Valley, Tanzania

    Author : Edmond Alavaisha; Regina Lindborg; Steve Lyon; Jennie Barron; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecosystem services; land use change; management practices; fertilization; irrigation; water quality; and smallholder; Physical Geography; naturgeografi;

    Abstract : Land use change has major impact on the world’s wetland ecosystems and biodiversity. The motivation behind this change has been to increase agricultural production, often resulting in negative effects on water quality and soil fertility. READ MORE
