This talk of "nearly zero energy" is starting to get on my nerves. Isn't it really critical to set a baseline for what a serious attempt at "nearly zero energy" construction looks like in kWh/m2/year?

I can understand that is it very hard to set a target which all countries can share, but someone needs to draw a line in the sand and say "If you're not at least this good, then your not really taking this seriously". Setting this can also begin to force the needed work on finding agreement on how to calculate a buildings energy use.

So great brainstorm, valuable results. But we still need a measuring stick.
