    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.
