1. 6. Towards a Sustainable Food System : Entrepreneurship, Resilience and Agriculture in the Baltic Sea Region

   Författare :Markus Larsson; Rebecka Milestad; Höjer Mattias; Thomas Hahn; Lars Drake; KTH; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sustainable agriculture; eutrophication; Baltic Sea; entrepreneurship; resilience; sustainable food system; Hållbart jordbruk; övergödning; Östersjön; entreprenörskap; resiliens; hållbart livsmedelssystem; Planering och beslutsanalys; Planning and Decision Analysis;

   Sammanfattning : This thesis compares conventional agriculture and Ecological Recycling Agriculture (ERA) in terms of their environmental and socio-economic effects. Environmental effects include greenhouse gas emissions and energy use, but this analysis focuses on nutrient losses. LÄS MER

3. 7. Investments, system dynamics, energy management and policy : a solution to the metric problem of bottom-up supply curves

   Författare :Fabian Levihn; Cali Nuur; Henrik Blomgen; Filip Johnsson; KTH; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Investments; Energy Management; Policy; MACC; CSC climate change abatement; energy efficiency and conservation; system dynamics; Industriell ekonomi och organisation; Industrial Engineering and Management;

   Sammanfattning : Today, issues such as climate change and increased competition for scarce resources puts pressure on society and firms to transform. Change is not easily managed though, especially not when relating to production or consumption of energy carriers such as district heating or electric power. LÄS MER

4. 8. Energy System Collaboration as a Vital Measure to Improve District Heating Performance

   Författare :Gottfried Weinberger; Bahram Moshfegh; Shahnaz Amiri; Erik Dahlquist; Högskolan i Gävle; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy system collaboration; District heating; Industrial excess heat; Combined heat and power; Energy system optimization; Metamodeling; Building LCC optimization; Building energy simulation; Cluster energy renovation; Energisystemsamverkan; Fjärrvärme; Industriell överskottsvärme; Kraftvärme; Energisystemoptimering; Metamodellering; Byggnads-LCC-optimering; Byggnadsenergisimulering; Klusterenergirenovering; Hållbar stadsutveckling; Sustainable Urban Development;

   Sammanfattning : With joint commitments by twenty-seven countries under the Paris Agreement, the European Union envisioned a resource-efficient and competitive economy without net emission of greenhouse gases by 2050. Immediate and massive efforts across sectors of energy, industry, and buildings will be required, and district heating (DH), through its ability to integrate efficiency measures on the supply and demand side, can play a central role.

5. 9. System studies of the use of industrial excess heat

   Författare :Sarah Broberg Viklund; Magnus Karlsson; Mats Söderström; Semida Silveira; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; excess heat; waste heat; surplus heat; energy systems; greenhouse gas emissions; energy efficiency; energy policy; system studies;

   Sammanfattning : Energy, materials, and by-products, can be exchanged between companies, having positive effects in the form of improved resource efficiency, environmental benefits, and economic gains. One such energy stream that can be exchanged is excess heat, that is, heat generated as a by-product during, for example, industrial production. LÄS MER

7. 10. Understanding the system-level for Mobility as a Service : A framework to evaluate full-scale impacts of MaaS

   Författare :Bhavana Vaddadi; Anna Pernestål Brenden; Yusak Susilo; Mia Xiaoyun Zhao; Jeppe Rich; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mobility as a Service; system-level; perspective; framework; experiments; Machine Design; Maskinkonstruktion;

   Sammanfattning : Mobility as a Service (MaaS), as a concept, has been widely popularised and considered to hold promising potential in reducing travel-related environmental impacts and transforming our current transport system. MaaS enables intermodal travel by providing enhanced features for users to access multiple mobility services. LÄS MER
