  2. 1. Energy Efficiency in Residential Buildings in Mozambique - Measurements and Simulations

    Author : Gabriel Auziane; Byggproduktion; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy; Building; Measurements; Simulations; DEROB-LTH; Mozambique; Subtropical and Tropical climates; Energy efficiency; PV system; Electrical energy savings.;

    Abstract : Mozambique, situated in south-east Africa, has sub-tropical and tropical climate and plenty of natural resources for energy production. The country is however poor, and only about 25% of the population has access to electricity from the grid. READ MORE

  4. 2. Environmental Assessment and Strategic Technology Choice : The Case of Renewable Transport Fuels

    Author : Karl Hillman; Björn Sandén; Ken Green; Göteborg Chalmers Tekniska Högskola Miljösystemanalys Institutionen för energi och miljö; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; environmental assessment; life cycle assessment LCA ; socio-technical change; strategic technology choice; renewable fuels;

    Abstract : The scale of the required changes is huge, and time is limited if we are to avoid the most severe effects of climate change. To reduce greenhouse gas emissions from road transport, several fuels and electricity originating from renewable energy sources have been proposed, all of them in different stages of development and with various and shifting environmental impacts.

  5. 3. Exploring climate impacts of timber buildings : The effects from including non-traditional aspects in life cycle impact assessment

    Author : Diego Peñaloza; Magnus Wålinder; Matty Janssen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; life cycle assessment LCA ; timber buildings; biobased building materials; low-energy buildings; forest products; climate impact assessment; biogenic emissions; carbon storage; timing of emissions; Industrial Ecology; Industriell ekologi; Byggvetenskap; Civil and Architectural Engineering;

    Abstract : There is an urgency within the building sector to reduce its greenhouse gas emissions and mitigate climate change. An increased proportion of biobased building materials in construction is a potential measure to reduce these emissions. READ MORE

  6. 4. Utilization of local bioresources for transport fuels - System analysis for decision support

    Author : Muhammad Arfan; Ola Eriksson; Jonas Ammenberg; Högskolan i Gävle; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System analysis; local bioresources; transportation fuels; LCA; LCC; geography of transitions; Systemanalys; Lokala resurser; drivmedel; LCA; LCC; geografi och om-ställning;

    Abstract : This thesis presents a comprehensive system analysis of the utilization of biowaste and forest industry residues to produce transportation fuels. It explores various aspects such as the constraints to the production system’s value chain development, the utilization of the geographical proximity of biofuel technology innovation system components, environmental impacts, and economic costs.
