23 84 00 HUMIDITY CONTROL EQUIPMENT

.01  Application:

1. Application:
   1. Section 23 84 00 of this Standard is intended to cover special circumstances where the occupancy or a process requires humidification or dehumidification outside of the default indoor design criteria defined in Section 23 00 00. 
   2. Centralized or terminal humidification shall not be provided for ordinary space conditioning purposes.

      1. For reference to designer: Humidification systems have the potential to cause considerable damage to building envelopes and contribute to indoor air quality issues. OPP requires specific documentation and approvals to avoid the mis-application of these systems. The successful implementation of a humidification system requires a firm understanding of the environmental requirements, operational capabilities of the equipment, and coordination with other building systems.

   3. Humidification is only permissible to maintain specific environmental conditions for a special equipment or process. These special purposes shall be identified by the designer during the schematic design phase and are subject to review and approval by OPP.

      1. The designer shall document on the design drawings the required temperature/humidity ranges, operational tolerances, and location of all humidified spaces/equipment.

.02 Dehumidifiers

1. Small packaged dehumidifiers shall be arranged so condensate is piped to sanitary system.
