My project has 3 areas. Project AHU serves conditioned air to Area 1,2 and 3. The fresh air is supplied only to Area 1 directly from base building AHU due to constraints. Project AHU has RAD grilles near these fresh air grilles. The fresh air (as a part from recirculated air) is served to Area 2 and 3 by AHU. Is this strategy compliant?
Also, as per reviewer, space should be categorized as '100% OA'. But as per logic, it should be considered as Multi-zone since recirculated air is used for different Ventilation zone. Need guidance for this issue.
Thank-you
