Productivity is extremely difficult to measure - hence the need for proper peer review science.

What we need is independant 3rd party research, that is open to critical peer reviews, and tested by time.

Until then, be very very careful in what you choose to believe !!

Measuring increase in productivity and wellbeing is difficult but could be the biggest advantage to green construction.

The energy stuff is pretty easy to quantify, but this is the wild card. I find it very intersting though.

I added you to my blogroll.

Unless that .5% who claimed lower productivity reported extreme reductions (unlikely), they're not likely to skew the figures that much. For the purposes of this argument, let's assume they had a 5% reduction in productivity.

That leaves us with those reporting equal productivity (aka 0% increase in productivity) and those reporting higher productivity averaged at 4.88%. The no productivity folks account for 45% of the population and the higher productivity folks account for 54.5% of the population.

That leaves us with the following equation:

[(45%*0%)
+(54.5%*4.88%)
-(.5%*5%)]
/100
=
2.63% increase in productivity for all included

I did a bad job of pointing out the limitation of this particular study, namely that it is based on survey data. The figures related to the older studies are based on empirical data.

What's the average affect on productivity for ALL buildings? Not just those that show an improvement.
