    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

    Sammanfattning : Enligt lagen om kommunal energiplanering ska varje svensk kommun ha en energiplan för tillförsel för tillförsel och användning av energi. Huruvida energiplanering är ett bra sätt att styra det kommunala energisystemet är dock omdebatterat. LÄS MER

  4. 4. Understanding Energy Behaviour – A Necessity for Supporting Domestic Energy Conservation through Design

    Författare :Anneli Selvefors; Chalmers University of Technology; []
    Nyckelord :SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; HUMANIORA; SOCIAL SCIENCES; SOCIAL SCIENCES; HUMANITIES; Energy conservation; energy behaviour; domestic energy consumption; design for sustainable behaviour; energy feedback;

    Sammanfattning : Domestic energy consumption is continuing to increase and the need to decrease consumption is growing more evident. In this research, two studies were conducted to further the understanding of domestic energy behaviour and increase the knowledge of how energy conservation can be supported. LÄS MER
