Furthermore, all WELL buildings should be considered "accessible" building for the purposes of the law.

The French Law regarding PMRs or 'personnes à mobilité réduite' (French Decree No 2006-555 of 17 May 2006, or the latest adoption in effect at the project's registration date) is an acceptable equivalent to the American Disabilities Act (ADA) design regulations. Note, similarly to the application of the ADA to buildings in the US, the code must apply to all buildings. Furthermore, all WELL buildings should be considered "accessible" building for the purposes of the law.

Replace the existing Part 1 text with the following:

a. Current ADA Standards for Accessible Design
b. ISO 21542:2011 - Building Construction - Accessibility and Usability of the Built Environment, Appendix B: Standards"

The Dutch Integral Accessibility Standard is an accepted equivalent for the American Disabilities Act (ADA) design regulations. Note, similarly to the application of the ADA to buildings in the US, the Dutch Integral Accessibility Standard must apply to all buildings. Furthermore, all WELL buildings should be considered "accessible" building for the purposes of the code.

The Building Requirements for Persons with Disabilities from British Columbia Building Code has been deemed equivalent to the ADA for Feature 72. Note, similarly to the application of the ADA to buildings in the US, the BC Building Code must apply to all buildings. Furthermore, all WELL buildings should be considered "accessible" building for the purposes of the code.

The UK Part M Volume 2 Standard (Buildings other than dwellings) may be used lieu of the 2010 ADA Standards for Accessible Design as long as the following additional requirements are met:

1. Signage adheres to the requirements of BS 8300: Design of buildings and their approaches to meet the needs of disables people, as referenced within the Part M Volume 2 Standard.
2. Drinking fountains adhere to the requirements of ADA Standards for Accessible Design, Sections 211 and 602 for Drinking Fountains.

In part description, remove: "At least 30%...of the following". Add: "At 30% of workstations that are at seated height or similar work surfaces, users have the ability to alternate between sitting and standing through one of the following:"

Singapore SS 553 (2016) CP Standard has not been accepted as an equivalent for ASHRAE 62.1-2013 of Feature 03. Note the building/occupancy types indicated in the Outdoor Air Supply Requirements (Table 1) is not sufficient to cover all buildings and space types for all projects in Singapore.

For Part 3b, add: "or BIFMA G1 guidelines" after "...HFES 100 standard"

Code NPR 1813 has been accepted as an alternative to HFES 100 for the requirements of Feature 73 Part 3.

In Part 4a, remove: "employees" after "reaching requirements for". Add: "occupants" after "reaching requirements for"

Remove: "employee". Add: "occupant"

For Feature 73, Part 2, the project may provide height adjustable tables and meeting tables apart from workstation desks to meet the feature requirements.

In the Feature description, remove the second paragraph. Replace with the following text:
'Intent: To reduce physical strain and maximize ergonomic comfort and safety.'

In Part 2a, change "Adjustable Height standing desks." to "Adjustable height sit-stand desks."

Add Owner Letters of Assurance as required documentation, add on-site spot checks as required verification, remove visual inspections.

Remove: "6,000 m²". Add: "1,900 m²"

The Code for Design of Sound Insulation of Civil Buildings’ (B50118-2010) and ‘Environmental Quality Standard for Noise’ (GB3096-2008) have been approved an acceptable method to comply with F74.

NEN 5077:2006 has not been accepted as an alternative for the requirements of Feature 75 Part 2. Note that the requirements of Feature 75 list specific noise criteria requirements for space types whereas NEN-EN 5077:2006 takes into account an averaged sound pressure level measurement of a space but does not correlate this result to a noise criteria element specific to space type.

In Verification Method, remove: "Letter of Assurance". Add: "Annotated Document"

Add: "spaces and potential sources of disruption" after "the following"

Add: "," after "as well as occupants themselves"

Remove: "To reduce acoustic disruptions and increase speech privacy by
creating an acoustic plan and limiting internal noise levels." Add: "To reduce acoustic disruptions from internal noise sources and increase speech privacy."

In the Feature description, remove the second paragraph. Replace with the following text:
'Intent: To reduce acoustic disruptions and increase speech privacy by creating an acoustic plan and limiting internal noise levels.'

In Part 2a, change “Open office spaces and lobbies:” to “Open office spaces and lobbies that are regularly occupied and/or contain workstations:”

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"

Add: "(including circulation areas)" after "mechanically-ventilated projects"

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.

Core and Shell projects pursuing WELL compliance may submit Feature 77 as an Innovation feature under Features 101-105, provided all parts of the Feature are met for the whole building scope (i.e. The building core and shell and all parts of the interior finish-out that are completed by the project owner).

Remove: "3,000 m³". Add "280 m³"

Remove: "6,000 m³". Add "570 m³"

In Part 1b, change “Open office spaces:” to “Open workspaces:”

AS/NZS 2107:2016 has been accepted as an alternative to the sound masking level requirements in Feature 79 Part 2.

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

In the Feature description, remove the second paragraph. Replace with the following text:
'Intent: To reduce sound transmission and acoustic disruptions through sound barriers.'
