I recall someone once asked about the time needed to be spent on LEED
certification. Well, I have just come across a report prepared by
Northbridge Environmental Management Consultants
entitled Analyzing the Cost of obtaining
LEED Certification, which is available online at the following link:

stofLEED.pdf

It indicates that the documentation takes 226 working hours on average to
prepare and costs between US$8,000 - US$70,000 per project: the first
project costing between US$30,000 - US$60,000.
