Abstract [en]

Energy efficiency could be described as ”using less energy to provide the same service”.  There are many motivations to improve energy efficiency in buildings, for example financial cost savings to consumers and at the same time a reduction of the environmental and climate impact.

In my thesis, I have on behalf of the real estate ”Skelleftebostäder” investigated one of their multi-residential properties to study possible energy efficiency improvements, such as replacement of the ventilation system, new windows and insulation of the attic floor. Life cycle cost analyzes have also been calculated to analyze how much each action will cost based on its lifetime, compared to if no action would be done.

The work has mainly been conducted through literature studies with the use of the simulation program IDA ICE, where a model of the property has been constructed according to current conditions and energy needs. Subsequently, the simulations carried out for each energy efficiency act have then been compared with a reference house.

The results showed that all the investigated energy efficiency acts would reduce the property´s energy use mainly by changing the ventilation system (which would reduce the property's energy performance by up to 35 %). Minimum savings of energy would additional insulation of the attic floor give; It would only reduce the energy performance by 4%. Of all the investigated energy efficiency acts and with regard to their life-length, it is however only new windows which turned out to be economical profitable for this building.
