Based on the review, it is clear that 11 credits can be achieved. A total of 22 credits must be achieved to qualify for Bronze certification. Following is a list of the elements that may not support LEED, along with recommendations for actions to obtain the indicated credit. Please review these items and determine if it is feasible to make the necessary modifications to obtain the additional credits needed to make the building eligible for LEED certification. Also, please bear in mind that this is a pilot project to test the LEED program. We have the ability to suggest modifications to the requirements as long as they meet the intent of the credit.
