Productivity in green buildings?

An interesting survey from USA, adds more weight to benefit of building green or does it?  This report “Workers in green buildings take less sick leave” from Green Building Press states that a survey found that workers in green buildings were found to be more productive.

Now, one could argue that is one of the primary aims for building green, the largest cost centre is your employees, therefore even minor productivity improvements equates to a valuable dollar return for employers.

However, two points to consider.

First defining and measuring “productivity” is no simple matter, it’s a very subjective, unlike objective equipment meter readings, the exercise is wholly dependant on fuzzy variables such as the respondents mood and feelings. Certainly surveys are a useful, and providing snapshot of the current situation, but how will the employees, solar panels, or chiller performance look next year?  The next survey might provide a different outcome.

Secondly, the last part of this report is also instructive, it reveals that the respondents said they would not pay more for a green building!  Therefore, we could conclude that they wouldn’t actually trust the productivity findings, and that measuring workplace productivity remains an elusive goal.  Another possible but unlikely conclusion is that green building has finally become main stream, therefore “extra cost” is not an issue.

Unfortunately, the report doesn’t reveal if respondents would have pay more for a building with proven, independently verified, cost, energy, water, and carbon savings.
