Naturally Ventilated Spaces

Mechanically Ventilated Spaces

Determine the required ventilation rates for indoor spaces based on occupancy and space types.  ASHRAE 62.1-2004 tables 6-1 and 6-4 list minimum requirements for particular spaces.

Naturally Ventilated Spaces

Review the Ventilation Rate Procedure methodology in ASHRAE 62.1-2004 Section 6.2 and the associated Table 6-1.

Mechanically Ventilated Spaces

Check local building codes to determine requirements. The project must either meet ASHRAE 62.1-2004, or local codes if they are more stringent. Since ASHRAE 62.1-2004 is often more stringent than local codes, be sure to review and be familiar with its requirements.

This prerequisite is paired with EQc2: Increased Ventilation. If ventilation rates are targeted above the 30% ASHRAE requirement, projects can gain both the prerequisite and a point for EQc2. Projects pursuing IEQc2 may follow the compliance path for natural ventilation found in Chapter 2 of The CIBSE Applications Manual 10: 2005 (AM10) for both the prerequisite and for the credit.

Fixed partitions and office furniture apply to MRc3: Materials Reuse and not to MRc.1.3 Building Nonstructural Reuse.

The project does not need to achieve MRc1.1-1.2:  Building Structure Reuse to pursue MR 1.3: Building Nonstructural Reuse.
