<p>This thesis is based on a case study for the real estate manager Mimer in Västerås. Mimer provides a great deal of this city’s rental apartments. Many of their buildings have ventilation systems with a type of heat-recovery called “heatpipe”. This case study focuses on two buildings which have certain problems with these heatpipes. The recovery rates of the existing systems are low, and one building suffers from a warm indoor climate in the summertime. Problems with the indoor climate seem to stem from a faulty installation of the heatpipe. This building does also have considerably higher energy consumption than the other one, which leads suspicions to overloaded fan motors.</p><p> </p><p>The main purpose of this study is to retrieve information about the present situation energy- and ecomonywise. A new type of heat recovery and new fans has been chosen by Mimer in order to calculate expected new energy consumption for these buildings. These values will lead to a few LCC calculations which show life cycle costs for the existing systems and the new systems. Based on the LCC calculations one or more options will be chosen as a recommended action for the ventilation systems. The recommendations will be analysed and discussed from different point of views that are relevant for a real estate manager.</p>
