Installationsituation
I want to use my own installation values
Ψ_up= W/(mK) Ψ_down= W/(mK)	Ψ_left= W/(mK) Ψ_right= W/(mK)
Or select certified Situation:	`U`_{W, installed} = ? W/(m² K)

Cost Calculation
Orientation :	Please choose orientation of the window to get the PHPP-standard values for solar radiation
