Our client is going into a LEED Certified building and will automatically get 5 points. However, when we will look at Option 2 - we can achieve up to 12 points by meeting several path requirements of the existing points that come with the building.

It's my interpretation you cannot combine Options 1 and 2. Therefore, what would be the pros and cons of skipping Option 1's 5 points and pursuing the possible 12 points by using the Option 2 method? We obviously want to the higher points to achieve a higher certification.
