  2. 11. Modelling Life Cycle Cost for Indoor Climate Systems

    Author : Dennis Johansson; Institutionen för bygg- och miljöteknologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HVAC; life cycle cost; energy; Energy research; Energiforskning; Byggnadsteknik; Building construction; indoor climate system; ventilation; maintenance; LCC;

    Abstract : The indoor climate system, which serves a building with a proper indoor air quality and thermal comfort, has been predominantly designed based on the initial cost. A life cycle approach could improve both the economic and environmental performance since the energy use could decrease. READ MORE

  4. 12. Food, energy and the environment from a Swedish perspective

    Author : Rebecka Engström; Göran Finnveden; Roland Clift; KTH; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Input-Output Analysis; Life Cycle Assessment; Sector; Consumption changes; Energy Analysis; Food Losses; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : Det särskilda sektorsansvaret är en ordning inom miljöpolitiken som innebär att varje sektor har ansvar för att hantera de miljöproblem som orsakas inom sektorn. På grund av detta ansvar finns ett behov av att kartlägga miljöproblem från sektorer, att identifiera de viktigaste problemen och att hitta strategier för att minska miljöpåverkan. READ MORE

  5. 13. Energy renovation of multi-family buildings in Sweden : An evaluation of life cycle costs, indoor environment and primary energy use, and a comparison with constructing a new building

    Author : Lina La Fleur; Bahram Moshfegh; Patrik Rohdin; Andreas Koch; Linköpings universitet; []
    Keywords : ;

    Abstract : Residential buildings account for 27% of the final energy use in the European Union. In cold climates, space heating represents the largest proportion of the energy demand in residential buildings. By implementing energy efficiency measures (EEMs) in existing buildings, energy use can be significantly reduced. READ MORE

  6. 14. Receiver Front-Ends in CMOS with Ultra-Low Power Consumption

    Author : Carl Bryant; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; receiver; front-end; sensor networks; CMOS; ultra-low power; low noise amplifier; mixer; voltage-controlled oscillator; frequency divider; bluetooth;

    Abstract : Historically, research on radio communication has focused on improving range and data rate. In the last decade, however, there has been an increasing demand for low power and low cost radios that can provide connectivity with small devices around us. READ MORE

  7. 15. Diffusion of Battery Electric Vehicles : The Role of Total Cost of Ownership

    Author : Jens Hagman; Sofia Ritzèn; Johan Jansson; KTH; []
    Keywords : Total cost of ownership; electric vehicles; e-taxis; vehicle salespeople; Machine Design; Maskinkonstruktion;

    Abstract : Due to their high efficiency, zero tailpipe emissions and possibilities of using renewable electricity, Battery Electric Vehicles (BEVs) have been proposed as a way to alleviate the negative consequences of transport. However, as with other energy-efficient innovations market uptake or diffusion of BEVs have so far been limited. READ MORE
