We design HVAC systems for toxic release shelters (TRS) to protect occupants during chemical releases, smoke events, or external contamination scenarios. This includes shelter pressurization strategy, filtered air supply design, leakage management, and operational modes for normal use versus emergency isolation.
Our engineering addresses:
- Filtration selection (particulate and gas-phase media depending on hazards)
- Pressurization targets
- Door/penetration sealing approach
- Monitoring instruments (pressure differential, CO₂, filter status)
- Emergency operating procedures.
We also consider occupant load, heat gain, and comfort to ensure the shelter remains habitable for the intended duration.
Deliverables include:
- Design basis
- Equipment sizing
- Controls concept
- Drawings
- Commissioning/testing requirements.
Need to upgrade your shelter ventilation and pressurization strategy? We can help with the right concept design.
