I develop system-level ventilation architectures that treat ventilation as a load-reduction problem rather than a conditioning problem.
My work focuses on recovery-first approaches in which passive recovery stages reduce ventilation loads upstream, allowing downstream HVAC systems to operate only on residual load.
The architecture supports both retrofit and packaged embodiments and is compatible with a wide range of existing HVAC configurations.
I am currently engaging with HVAC manufacturers and building-systems partners on evaluation and potential collaboration.
