I have a project that a contractor assumed that 2-layers of MERV 7 filtration would equate to a MERV 8 filter. When the filter manufacturer was contacted to confirm the contractor's assumption they inidcated that there was no supporting documentation or calculations to backup the assumption. Knowing this, is there another option of achieving this credit?

Assuming this is in the past tense and air handlers were used during construction, I don't know of a way for you to earn the credit.

Thank you for the reply.
If the ductwork was thoroughly cleaned and the proper filtration added after the cleaning would this achieve the credit?

Franklin- there is no existing alternative compliance path that would cover the strategy you are proposing. You could certainly chose to submit your actions in the "alternative compliance path" portion of the LEED template, but since there is nothing that really allows you to use the method you are proposing, it would be up to the GBCI reviewer's discretion as to if you are awarded the credit or not. Since the credit language is so clear in requiring MERV 8, I would be surprised if they award you the credit.
