Flexibel isolering av fönster för att minska energiförluster
The first part of this essay is about a single-family house that we have planned and projected. Thesecond part is a deeper study in ways to further insulate windows when they are not in use.In the first part the building?s design and its most important construction elements are described.The planning of all major installations (heating, domestic water, ventilation, sanitation, electricity)are reported so that one can in principle start construction of the house. In addition there arecalculations done on the building?s energy management.The result is a two stored house angled toward the south. The ground floor has a spacious kitchenand living room in an open floor plan, while the upper floor has more separated bedrooms. Thehouse gets its heat from a geothermal heat pump and is very well insulated. This makes the houseenergy efficient and it easily meets Boverket?s requirements regarding energy consumption.The second part of the work is a deeper study dealing with window insulation. With windowinsulation is meant removable and insulating constructions that are in use for instance on nights, butcan be removed when the windows are needed for daylight and view. The effect on the energy lossthrough windows with different systems of window insulation is examined.We conclude that there is money to be saved with such designs. Perhaps most interesting is that ourenergy calculations show that even with simple types of window insulation, such as blinds andcurtains, a lot of energy can be saved. Such simple systems has, in our opinion, the greatest potentialfor the future since they are relatively inexpensive and do not impact the building?s façade much.
