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.

As part of documentation submission, projects may optionally submit design values for clothing insulation (CLO) and metabolic rate (MET) which will be used in calculations to determine compliance of performance testing results. Projects may submit multiple CLO and MET values which may vary by time of year.

All occupiable spaces in naturally-conditioned projects meet the following criteria:

In 17 Jan, 2017 AAP, remove: "Core and Shell residential" before "projects may fulfill…". Add: "Residential"

Previously published as AAP:
ISO 7730:2005 and/or CEN Standard EN 15251:2007 may be used in lieu of ASHRAE 55-2003 Sections 5.3 and 5.4. The requirements of these standards must be met in all spaces, rather than 75% of regularly occupied spaces in the project. When selecting either ISO 7730:2005 or CEN Standard EN 15251:2007, the most appropriate standard must be selected for the space. Note that some naturally ventilated spaces may not qualify to use CEN Standard EN 15251:2007 if certain criteria are not met.

In addition, when utilizing CEN Standard EN 15251:2007, the project must comply with either Category I or Category II as described in Table A.1 of the standard in order to be within +/- 0.5 of the PMV for the space.

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

Residential projects may fulfill the requirements of Feature 76 by providing a narrative of how the residential units meet local thermal comfort standards (environmental factors: air temperature, humidity, radiant temperature, air speed and personal factors: metabolic rate and clothing insulation) or by providing an allowance for tenants to select an air conditioning unit of their choice from options, which would allow the unit to meet the thermal comfort requirements.

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.

For Part 1, remove:
"a. Negative pressurization.
b. Interstitial rooms.

For Part 1b, remove: "NIC" after "minimum". Add: "STC"

The China national standard 'Code for Design of Sound Insulation of Civil Buildings' (GB50118-2010) has been approved an acceptable method to comply with Feature 81, Part 1 when Dw levels under ‘High Limits’ are achieved. Note that projects must comply with the verification method according to Appendix D.

Add Contractor Letter of Assurance as required documentation.

To meet the requirements of Feature 82 Part 1 and 2, projects may implement the following strategies:

• Operative temperature can be adjusted by +/- 1.5 °C per 4.05 m [13.28 ft] zone edge dimension.
• Occupants have the ability to set their preferred zone temperature.
• Occupants have access to personal thermal comforts devices such as fans (excluding space heaters).

In Part 2a, remove: "employees". Add: "occupants"

In Part 1a, change “The building provides a thermal gradient of at least 3 °C [5 °F] across open office spaces…” to “The building provides a thermal gradient of at least 3 °C [5 °F] across open workspaces…”

As an alternative to Feature 83 Part 1, projects may use active chilled beams that integrate outdoor air supply, so long as the following conditions are met:

• At least 50% of the thermal effect is from radiant heat transfer.
• The outdoor air is introduced laterally at the surface of the chilled beams.
• There is no supplemental floor-mounted conditioning or ventilating equipment at the perimeter of the space.

In Feature introduction text, change “Additional benefits include saved floor space, lower dust transportation and increased thermal comfort through the separation of temperature controls and fresh air supply systems” to “Additional benefits include saved floor space, lower dust transportation and increased thermal comfort through the separation of temperature controls and outdoor air supply systems

Annotated Documents: Professional Narrative
On-Site: Visual Inspection
