A difficalt case: Radiant floor + Nat Vent
LEED increased ventilation credit requires that when using the macroscopic airflow simulation compliance path for naturally ventilated spaces:
1) 90% of the occupied spaces are prooven to be able to provide the required ventilation requirements as per the chosen standard (normally 62.1)
2) these ventilation requirements should also be consistantly applied to the energy model of EAp2 (note only occupied spaces are considered)
3) LEED has additional exhaust requirements for contaminated spaces (if IAQc5 is aimed for), which must also be considered by the increased ventilation credit and EAp2
Q) what ODA and or Exhaust requirements should be applied to the model in EAp2 to non-regularly occupied spaces (that are spaces without harmfull contaminants)?
E.g. WC, kitchen. Typically, naturally ventilated WCs and kitchens won't be expected to have ACH quite as high as 62.1 or is mech exhaust required for those space type examples?
