The objective of the paper is to compare central and decentralized air-handling units with regard to costs and suitability. It is mainly based on a calculation model for Life Cycle Costs (LCC), which has been used on two cases, one high-rise and one medium-rise office building. Qualitative evaluation of non-quantifiable factors supports the comparison. The results show that the decentralized solution in general has higher LCC, but buildings with side wings and fewer floors tends to even out the differences. Less need for shafts and large fan rooms make space available that can give income from rent that exceeds the extra LCC for the decentralized solution
