I'm developing an HVAC solution for a 400 sqft smudge room, where ceremonial burning of herbs will occur. This room, currently an unventilated storage space, has three exterior walls, a 10 ft ceiling, and a door leading directly outside, making infiltration a concern. The existing 10kW supplemental heater will remain. Due to the nature of smudging, dedicated supply and exhaust are required, independent of the building's existing ventilation. I've researched guidelines suggesting 2-12 ACH (133cfm - 800cfm) for exhaust during smudging, often timer-controlled for 45min-1hr. The space will be maintained at a negative pressure.
Space is limited (approx. 3 ft ceiling space available for equipment), and I'm trying to avoid roof-mounted equipment to minimize costs. The building is in climate zone 8 and uses electric heat (and while panel connections are available, they are limited to an extent). I'm exploring an HRV/ERV with electric duct coils, but the physical size of units capable of handling the larger air change rates is a major constraint.
I am looking for recommendations on:

I am looking for recommendations on:
- Optimal air change rates for a smudge room environment.
- Alternative ventilation strategies that can fit within the tight space constraints, while effectively removing smoke and maintaining air quality.
- Any other design considerations that I may have overlooked.
