Remove: "d. Teleconference rooms: maximum noise criteria (NC) of 20."

Remove: "major" after "occupants themselves can be"

Whereas Noise Criteria levels within a space is driven by sound produced by the HVAC and other mechanical systems which may be outside of a tenant’s control, New and Existing Interiors projects may achieve Feature 75 when achieving NC levels higher than listed, with the following conditions:
- Achieve NC levels of 5 higher, but the project is limited to Gold level of certification, no matter how many Optimization features are achieved.
- Achieve NC levels 10 higher, but the project is limited to Silver level of certification, no matter how many Optimization features are achieved.

Noise Rating curve values may be used in lieu of Noise Criterion curve values for the mechanical equipment sound levels required in Part 2 of this feature using the same maximum criteria values listed for each space type. The project team must indicate in their documentation application if Noise Rating is to be used in lieu of Noise Criterion.

Singapore Standard SS 554:2016 has not been accepted as an equivalent for ASHRAE 55-2013 of Feature 76. SS 554 does not appear to directly address metabolic rate or clothing insulation assumptions. Further, the submitted comfort analyses do not confirm that the design criteria listed in Table 1 meet ASHRAE 55-2013 requirements because the metabolic rate assumptions are inconsistent. Lastly, SS 554 does not appear to include design requirements because the limits listed in Table 1 are classified as recommended and are only referenced relative to audits of existing environments.
Please note that SS 554 Table 1 recommends using ISO 7730 as the analytical method for all thermal comfort parameters and ISO 7730 is already an approved equivalent. Please also 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.

In 09 Feb, 2017 AAP, add: "for cooling" after "…or air conditioning units"

Remove: "naturally-ventilated" after "All spaces in". Add: "naturally-conditioned" after "All spaces in"

Multifamily residential projects may certify when not supplying central-system air conditioning or air conditioning units for cooling in individual dwelling units, with the following conditions:
- Outdoor air is supplied at a volume to meet Feature 3 Part 4 and is filtered to meet Feature 5 Part 2.
- The developer allocates spaces for tenant-owned, supplemental air conditioning units to be installed.
- The developer supplies all occupants with tenant guidelines for selecting a high-performance air conditioner unit to maximize comfort and optimize efficiency. The guidelines should detail the importance of local thermal comfort standards including environmental factors of air temperature, humidity, radiant temperature, air speed; and personal factors of metabolic rate and clothing insulation.
- Projects using this option are limited to Gold level certification, no matter how many optimizations are achieved.

The Green Star Credit 14 is an accepted equivalent to the requirements of Feature 76: Thermal Comfort. Compliance with the Green Star credit is sufficient to comply with the requirements of Feature 76.

Inquiry: In residential units, are the requirements of Feature 76 met if individual unit controls for heating are provided?

Ruling: No, an exemption from ASHRAE 55 requirements may not be granted in residential units if individual unit controls are provided. It is typical for each unit in a multifamily residential development to have individual control over space temperatures with controls allowing occupants to adjust temperatures. In order to rely on the controllability of the systems as an alternative strategy, it must be demonstrated that the local controls allow occupants to set conditions within the unit to meet ASHRAE 55.
