Abstract [en]

To reduce energy consumption, a well-designed building envelope is required in order to minimize heat losses caused by transmission and air leakage. Therefore, it is important that the materials in an exterior wall construction meet the requirements so that an energy efficient building can be achieved. It is also important to examine how different materials affect the environment through carbon dioxide release due to their manufacture. At the same time as stricter energy requirements are to be achieved, it becomes increasingly relevant to build space efficient in the metropolitan areas.  To construct an exterior wall that is both well insulated and space efficient is a balance that must be considered. This degree project is based on a case study that compares two exterior wall constructions consisting of lightweight concrete or mineral wool with wooden studs. The case study is based on how the U-value of the exterior walls is affected by a specific exterior wall thickness and also how the wall construction and thickness is affected by a specific U-value. One study compares the transmission losses for all different walls and also for a one-family house including all different walls. For both mineral wool and lightweight concrete, it is important that the materials are as dry as possible in the wall construction, as drier materials have lower heat conductivity. The exterior wall consisting of lightweight concrete will have a higher U-value compared to the exterior wall of mineral wool with wooden studs when the exterior wall thickness is specified. The wall consisting of lightweight concrete need to be thicker compared to the wall of mineral wool with wooden studs to achieve the same specified Uvalue. The exterior wall consisting of lightweight concrete will cause a higher carbon dioxide emission per square meter of wall compared to the exterior wall consisting of mineral wool combined with wooden studs. A higher U – value results in higher transmission losses. A thicker of the exterior wall will lead to a larger building area or a smaller usable floor area that will have a great impact on the economy.
