In order to comply with LEED IEQc5, do we need to provide MERV-13 filters for the supply air of a very large warehouse? The warehouse is expected to be “regularly” occupied. Currently the warehouse has roof mounted exhaust fans to reduce summer time over-heating, with louvers providing make-up air. There is no heating, cooling or air handling equipment needed, the building is naturally ventilated year-round with the exception of the exhaust air fans. It would not be practical to install MERV-13 filters behind the louvers, as the resistance to air flow is too great. The only option would be to install supply fans with filters and this would greatly increase the energy consumption of the building, as the airflow is huge. I'd appreciate your thoughts. Thanks. David

David, yes, you would need to provide MERV 13 filtration. As with many credits, there are trade offs that the team would to make decisions on. This may or may not be the most appropriate credit for your project to pursue.

Hi Mara,
I am in the same situation as David.
I Just checked the very last comment for this credit (page 4), "MERV 13 filter and natural ventilation".
Tristan replied on his side that if there is no mechanically supplied air in the building then MERV 13 requirement would not applied.
I would have said the same. There are other requirements to meet in this credit. Does your statement come from a past project of yours?
Thank you, Renaud.
