Window placement and configuration has noticeable influence on
both heating demand and electricity consumption. When building
low-energy buildings, the thermal performance of the windows has
even greater significance and can be important for reaching the
desired energy goal.
But how do you ensure that you have chosen the most
There is no clear answer to that question, since it requires a
weighting of different values in relation to the specific context
in which they are placed.
Our experience is that the energy balance approach is the best
guiding principle on south-facing windows, whereas windows
facing north should be optimized toward the lowest
