  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 Use, Efficiency Gains and Emission Abatement in Transitional Industrialised Economies: Poland and the Baltic States

    Författare :Jürgen Salay; Miljö- och energisystem; []

    Sammanfattning : This thesis is a study of how energy use and air pollution in Poland, Estonia, Latvia and Lithuania have been affected by the economic transition after 1989. It consists of six articles, which examine three different aspects of these changes. LÄS MER

  4. 3. Energy analysis for sustainable mega-cities

    Författare :Aumnad Phdungsilp; Björn Palm; Ivo Martinac; Charles Heaps; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Asian mega-cities; energy demand; metabolism of cities; energy modeling; sustainable energy; energy planning; multi-criteria decision-making; Mechanical energy engineering; Mekanisk energiteknik;

    Sammanfattning : ABSTRACT Cities throughout Asia have experienced unprecedented economic development over the past decades. In many cases this has contributed to their rapid and uncontrolled growth, which has resulted in a multiplicity of problems, including rapid population increase, enhanced environmental pollution, collapsing traffic systems, dysfunctional waste management, and rapid increases in the consumption of energy, water and other resources.

  5. 4. 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.

  7. 5. Energy Efficiency Improvements of Tumble Dryers : -Technical Development, Laundry Habits and Energy Labelling

    Författare :Lena Stawreberg; Lars Nilsson; Jonas Berghel; Roger Renström; Björn Palm; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; drying; domestic; energy efficiency; textile; energy labelling standard; Thermal energy engineering; Termisk energiteknik; Miljö- och energisystem; Environmental and Energy Systems;

    Sammanfattning : Tumble dryers are becoming more and more common in ordinary households as a complement to the washing machine. Tumble dryers offer a fast drying cycle independent on weather conditions and require small space. They do, however, considering the large number of units use a large amount of electricity. LÄS MER
