On the energy saving side...

I have measured how much energy (and money!) I save with Optoglas with respect to one glazing: it is about 600KWh/year for each covered square meter of windows (roughly 500 NOK or 65€). With an average cost of 2000NOK/m^2 (260€), the break even point of my investment is in 4-5 years. Not bad!
