1. 1. Energy Management in Large scale Solar Buildings : The Closed Greenhouse Concept

   Författare :Amir Vadiee; Viktoria Martin; Philip Griffiths; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal Energy Storage; Energy Saving; Thermoeconomic Assessment; Energy Management Scenario; Micro Climate Control; Solar Building; Closed Greenhouse; SRA - Energy; SRA - Energi;

   Sammanfattning : Sustainability has been at the centre of global attention for decades. One of the most challenging areas toward sustainability is the agricultural sector. Here, the commercial greenhouse is one of the most effective cultivation methods with a yield per cultivated area up to 10 times higher than for open land farming. LÄS MER

3. 2. The Non-Energy Benefits of Industrial Energy Efficiency : Investments and Measures

   Författare :Therese Nehler; Patrik Thollander; Elin Svensson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial energy efficiency; energy efficiency measures; energy efficiency investments; non-energy benefits; compressed air;

   Sammanfattning : Improved industrial energy efficiency is viewed as an important means in the reduction of CO2 emissions and climate change mitigation. Various energy efficiency measures for improving energy efficiency exists, but even evaluated as cost-effective, there seems to be a difference between the energy efficiency measures that theoretically could be undertaken and which measures that actually are realised.

4. 3. Impact of climate change on integrated resource systems- Insights from selected East African case studies

   Författare :Vignesh Sridharan; Mark I. Howells; William Usher; Sonia Yeh; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; climate change; integrated assessment; Uganda; agriculture; water and energy systems; climate resilience; CLEW nexus; Energy Technology; Energiteknik;

   Sammanfattning : With countries revisiting their climate pledges agreed at the conference of parties (COP) in Paris, in 2015, the discussion on the impact of changes in the long-term climate on natural resources has never been more relevant. Specifically, since the 2011 Bonn conference on the nexus between resource systems, the interlinkages between energy, water and land resource systems and their climatic connections are on the radar.

5. 4. Biomass in a Sustainable Energy System

   Författare :Pål Börjesson; Miljö- och energisystem; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kontroll av utsläpp; Miljöteknik; pollution control; Environmental technology; economic valuation; environmental impact; carbon dioxide; Biomass; energy efficiency; Energiforskning; Energy research;

   Sammanfattning : The increased use of biomass for energy is as a key strategy in reducing carbon dioxide (CO2) emission, which represents the largest anthropogenic contribution to the greenhouse effect. In this thesis, aspects of an increase in the utilisation of biomass in the Swedish energy system are treated. LÄS MER

7. 5. Buildings' Transition to Active Nodes: Assessing the Viability of DC Distribution, PV and Battery Storage

   Författare :Patrik Ollas; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Buildings; Battery storage; Energy management; Solar photovoltaic; Direct current;

   Sammanfattning : Historically, buildings have been passive nodes in the electric grid system with one-way power flows. However, with the recent market development of solar photovoltaic (PV) and stationary behind-the-meter battery storage systems, buildings are now transitioning to active nodes, offering bi-directional power flows.
