Heating and cooling new office buildings at Arlanda airport (English)
Abstract [en]

This thesis consider alternatives for heating and cooling planned office buildings at Arlanda airport. The thesis is divided into three parts where the third part is a shorter synthesis of the two first. In the first part the energy demands of the buildings are modelled in a computer program. Two different building models are created, one more conventional and one with good energy properties. The results shows that with proper construction and ventilation systems etc. the energy required for heating and cooling could be very low. Whether the consumption will be so low that normal energy installations could be omitted is although hard to predict from the results. The second part of the work concerns different ways of producing the required energy for the buildings. Four energy producing systems (aquifer, rape seed diesel generator, snow-cooling and air blast cooler) are compared with today’s systems (districts heating and compression cooling machines) with respect to environmental impact and economy. District heating and diesel generator with rape seed oil are systems with negative global warming potential, mainly due to the simultaneous production of power together with heat. Compression cooling has the highest GWP and the remaining systems shows a small GWP. Rape seed diesel generator and (in less extent) district heating has a relative large impact on acidification and eutrophication while the other systems have a much smaller impact. Economically the aquifer and air blast cooling are the most competitive systems; the per-kWh price of energy is lower than for today’s systems. Snow cooling also has promising economical potential but the high price on rape seed oil makes the diesel alternative less interesting at the moment.
