1. 1. Energy Analysis of the Closed Greenhouse Concept : Towards a Sustainable Energy Pathway

   Författare :Amir Vadiee; Viktoria Martin; Halime Paksoy; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal energy storage; closed greenhouse; energy analysis; energy management; SRA - Energy; SRA - Energi;

   Sammanfattning : The closed greenhouse is an innovative concept in sustainable energy management. The closed greenhouse can be considered as a large commercial solar building. In principle, it is designed to maximize the utilization of solar energy through seasonal storage. In a fully closed greenhouse, there are not any ventilation windows. LÄS MER

3. 2. 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

4. 3. The zone concept : design of low-voltage installations considering the spread of high frequency harmonics

   Författare :Martin Lundmark; Magnus Olofsson; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric Power Engineering; Elkraftteknik; Energy Engineering; Energiteknik;

   Sammanfattning : The use of electric power has become a backbone of the modern society. Together with the growth in possible applications of electric power, we also see a growth in the number of devices and the interest of using electrical energy as an environmentally-friendly alternative to other sources of energy.

5. 4. Between the Paths of Modernity : The European Commission’s Shaping of European Nuclear Energy Policy between 1999 and 2012

   Författare :Julia Schwabecker; Jonas Anshelm; Björn-Ola Linnér; Eva Lövbrand; Susan Baker; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sustainable development; European Union; nuclear energy; environmental policy; energy policy; frame analysis; reflexive modernization; Hållbar utveckling; EU; kärnkraftspolicy; miljöpolicy; energipolicy; frame analys; reflexiv modernisering;

   Sammanfattning : A powerful symbol of modernity, in its early days, nuclear energy was associated with images of progress and dreams of a better life. At the start of the European process of integration, it was hoped that peaceful cooperation in nuclear matters would bring about lasting peace in the European continent. LÄS MER

7. 5. Low-energy buildings : energy use, indoor climate and market diffusion

   Författare :Johannes Persson; Stefan Grönkvist; Svend Svendsen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; building energy simulations; energy efficiency gap; energy use; indoor climate; low-energy buildings;

   Sammanfattning : Low-energy buildings have, in recent years, gained attention and moved towards a large-scale introduction in the residential sector. During this process, national and international criteria for energy use in buildings have become stricter and the European Union has through the Energy Performance of Buildings Directive imposed on member states to adapt their building regulations for ‘Nearly Zero Energy Buildings’, which by 2021 should be standard for new buildings.
