Abstract [en]

The first part of this essay is about a single-family house that we have planned and projected. The

second 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 are

calculations done on the building’s energy management.

The result is a two stored house angled toward the south. The ground floor has a spacious kitchen

and living room in an open floor plan, while the upper floor has more separated bedrooms. The

house gets its heat from a geothermal heat pump and is very well insulated. This makes the house

energy 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 window

insulation is meant removable and insulating constructions that are in use for instance on nights, but

can be removed when the windows are needed for daylight and view. The effect on the energy loss

through 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 our

energy calculations show that even with simple types of window insulation, such as blinds and

curtains, a lot of energy can be saved. Such simple systems has, in our opinion, the greatest potential

for the future since they are relatively inexpensive and do not impact the building’s façade much.
