Energieffektivitet av ett gammalt tegelhus

Sammanfattning: Much attention has been put on making new buildings have a "low energy" standard, but old buildings also need to become more energy efficient. In this paper, the emphasis has been put on trying to insulate the house so much that it complies with BBR's requirements. The house chosen is a house that is almost entirely constructed of brick. Exterior walls consist of double brick with an air gap in between and Tretex fiberboard on the inside (interior wall). The inner walls are also completely of brick with a plastered exterior. On the exterior facade you can see the town's brick from the time when the brick factories were still running. It is therefore essential that the building is not insulated on the outside so that the bricks do not get covered. The village where the building is located is also listed, which means that anachronistic appearance changes are not allowed. The result was surprising. It does not take much insulation to keep energy use to an approved level, in accordance with BBR. Even if one had chosen wood burning as a heat source in this house, it is likely that an equally good result can be achieved with electric heaters and heat pumps. Any prints should be made in color for all images to be clear enough.
