I would take issue with Mr Phinney's implied estimate that you can do all the LEED consulting and meet all the requirements for less than $10,000 on a large project. We will be releasing a study soon of an actual university project that used both standards, with side by side cost comparisons of facilities staff time that shows a significant disparity in time required for compliance with the two standards, with Green Globes cheaper by 60% in terms of staff time. On a major project, that will add up to a lot more than the disparity in registration costs.
