    Sammanfattning : Energy use in the European Union is increasing. At the same time, it is estimated that by the year 2050 most of the EU population will be living in currently existing buildings. Some of these buildings are or will be in need of renovation, and they have identified a target to reduce overall energy use. LÄS MER

  3. 22. Environmental Assessment of Buildings and the influence on architectural design

    Författare :Marita Wallhagen; Göran Finnveden; Mauritz Glaumann; Tove Malmqvist; Ole Jörgen Hanssen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; green building; sustainable building; environmental assessment; assessment tool; architectural design; CO2 Carbondioxide ; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

    Sammanfattning : This licentiate thesis examines environmental assessment tools for buildings. This is done by investigating, analysing, comparing and testing how different environmental assessment tools measure the environmental performance of buildings and examining the consequences this may have on architectural design.

  4. 23. Enhancing the Treatment of Systems Integration in Long-term Energy Models

    Författare :Manuel Welsch; Mark Howells; Erik Ahlgren; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power system models; Energy system models; Resource system models; Smart Grids; Operating reserve; Biofuels; Sub-Saharan Africa; Ireland; Mauritius; ; kraftsystemmodeller; energisystemmodeller; resursmodeller; smarta elnät; operativ reservkapacitet; biobränslen; Afrika söder om Sahara; Irland; Mauritius; ; SRA - Energy; SRA - Energi;

    Sammanfattning : Securing access to affordable energy services is of central importance to our societies. To do this sustainably, energy systems design should be – amongst other things – environmentally compliant and reconcile with the integrated management of potentially limiting resources. LÄS MER

  5. 24. Natural and social dimensions of forest carbon accounting

    Författare :Wilhelm Dubber; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Forest carbon fluxes; REDD ; boreal forest; LPJ-GUESS; BIOME-BGC; remote sensing;

    Sammanfattning : Global forests store large amounts of carbon both in living biomass and in the soil. The ability of forests to counteract climate change by acting as carbon sinks have been recognized in global climate politics, such as the 2015 Paris agreement which calls for national commitments to reduce greenhouse gas emissions.

  7. 25. The palaeolimnological record of regime shifts in lakes in response to climate change

    Författare :Linda Randsalu Wendrup; Kvartärgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; palaeolimnology; regime shifts; thresholds; alternative stable states; climate change; ecosystem dynamics; diatoms; hydrocarbons; monitoring; lake sediments; shallow lakes; 8.2 ka event;

    Sammanfattning : Regime shifts in lake ecosystems can occur in response to both abrupt and continuous climate change, and the imprints they leave in palaeolimnological records allow us to investigate and better understand patterns and processes governing ecological changes on geological time scales. This thesis aims at investigating palaeolimnological records of regime shifts in lakes during the Holocene to explore how lake ecosystems responded to climate changes and anthropogenic activities and to identify thresholds or tipping points that produced regime shifts.
