Version 2020 08/14/2020 - 14:27 6.0303.1r Hot-humid climate considerations

In climate zones 0A, 1A, 2A (as defined by ASHRAE 62.2) it is preferential to install an ERV rather than an HRV

Do not terminate ventilation air intake at the roof

Determine whether net latent load from ventilation (both natural and mechanical) requires dehumidification; if so, install dehumidification

Prevent excessive heat and moisture from entering the ventilation air.
