Yes MERV 13 filters are required. The other mandatory requirements may be found at http://www.leeduser.com/credit/NC-2009/IEQc5?page=0#lang-tab
I found this article regarding VRF and LEED, with the caveat that I am not endorsing it.

Merv 8 filters on the fan coil units. Merv 13 on your outside air unit or intakes. If you are ventilating by natural ventilation then your proabably can't get this credit. With a dedicated outside air unit this is easy.

Hellow,
I will apperciatte clarification on this issue.
I am trying to figure out wether MERV 8 instead of MERV 13 filters are adecuate to achieve this credit for A/C systems such as fan coils and VRF. But the responses to this comment are confusing.
Some people say MERV 13 is mandatory and other that MERV 8 is enough.
Thank you,

The credit requirements are:
1. Install 10' entryway systems at all regularly used exterior entrances to the building. If roll-out mats are used they must be maintained weekly by a contracted service.
2. Exhaust rooms where hazardous gases or chemicals are present; exhaust rate must be at least 0.5 cfm per square foot; pressure differential must be at least 5 Pascals on average and 1 Pascal at a minimum when the doors are closed. Provide self-closing doors for these rooms. Provide hard-lid ceilings or deck-to-deck partitions.
3. All outdoor air that is mechanically supplied to occupied spaces must be provided with MERV 13 filters; be sure to install these filters after construction and prior to occupancy. Naturally ventilated buildings can achieve this credit, it's just that this part of the credit requirement is not applicable. Outdoor air provided to unoccupied rooms (e.g. mechanical rooms, inactive storage, etc.) is not required to be provide with MERV 13 filters. There are no filter requirements for return, transfer, relief, exhaust air streams.
Good luck!
