Singapore SS 553:2016 CP Standard has not been accepted as an equivalent for ASHRAE 62.1-2013 of Feature 03. SS 553 Table 1 does not address all applicable and expected space types within an office occupancy. Note also that all Equivalencies are precedent-setting meaning that review of potential equivalent standards or codes cannot be conducted on a project-specific basis. Equivalency proposals must address the variety of project and space types present in the original code or standard. Further, in some cases, the ventilation rates listed in SS 553 Table 1 appear to be less than the default ventilation rates listed in ASHRAE 62.1-2013 Table 6.2.2.1 for the same occupancy types.
Please note that it is acceptable for the project team to bring on another individual with experience using ASHRAE standards to verify design compliance and sign the LOA (e.g. as a peer review), if they wish and/or the engineer of record is unable to do so.

Field and Laboratory Emission Cell (FLEC) emissions testing is approved as an emissions testing methodology only for furniture and furnishings that are made up of a uniform material and have flat testing surfaces on which the FLEC emissions testing methodology may be applied. For example, flat surfaced cabinetry that is made up of a uniform material may be tested using this methodology. However, chairs that are made from a variety of materials that lack flat surfaces may not be tested using this methodology. The emissions test must be administered by a third party investigator with no affiliation with the project. The associated costs are the responsibility of the project team. Additional tests performed in accordance with ISO 16000 methodology must be performed for total aldehydes and 4-Phenylcyclohexane and must meet the thresholds specified in the WELL Building Standard.

ORIGINAL RULING (10/24/2016):
(Not approved)
GreenGuard Certification is not an accepted equivalent standard to the California Department of Public Health (CDPH) Standard method v1.1-2010 as specified in Part 4a of this feature. Therefore Greenstuf is not an acceptable material for newly installed thermal or acoustic insulation, based on the evidence provided. The excerpt taken from GreenGuard Standard Method for Measuring and Evaluating Chemical Emissions from Building Materials, Finishes and Furnishings Using Dynamic Environmental Chambers refers to the GreenGuard Children and School certification (now GreenGuard Gold Certification), which does in fact meet/exceed CDPH standards. However, according to the Material Safety Data Sheet provided, Greenstuf is GreenGuard Certified and is not GreenGuard Gold Certified.

UPDATED RULING (1/11/2017):
(Approved)
Greenstuf has been considered an acceptable material, as it complies with GreenGuard Gold Certification, which has been approved as an equivalent standard for Feature 04, Part 4.

For Feature 4, Part 5, as an alternative to the formaldehyde emissions thresholds cited in ANSI/BIFMA e3-2011 7.6.2, projects may use certain approved thresholds. For systems furniture laminates: CDPH Standard Method v1.1-2010 limits (9 ug/m3) may be used. For furniture substrates: CARB Phase II limits (50 ppb for hardwood plywood with veneer core, 50 ppb for hardwood plywood with composite core, 90 ppb for particleboard, 110 ppb for medium density fiberboard, and 113 ppb for thin medium density fiberboard) may be used. Additionally, note that the project will still be required to demonstrate Feature 01: Air Quality Standards.
