Energy terms

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 energy-efficient windows?

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 U-value.
