Feature 5: Air filtration
Post Date: 01 May, 2019
Multifamily residential projects may achieve Feature 5, Part 1 by providing subsidized rental of purification systems to tenants via a discounted rental rate of the dwelling unit. Project teams must demonstrate that the discounted rent is lower than the market value of the dwelling unit and that the difference will cover the rental of air purification devices. Tenants are required to sign an agreement for purchasing or leasing air purifier(s) in order to receive the discounted rate.
Post Date: 15 Aug, 2018
Remove: 27 Apr, 2017 AAP "Projects registered as... Feature 05, Part 1: Filter Accommodation."
Remove: "Rack space and fan capacity is in place for future carbon filters or combination particle/carbon filters." Add: "Rack space is available and rack location identified for future implementation of carbon filters or combination particle/carbon filters."
In the Feature description, remove the second paragraph. Replace with the following text:
'Intent: To remove indoor and outdoor airborne contaminants through air filtration.'
In a project with a split-system air conditioning unit that does not allow for accommodating MERV 13 filters, the following measures may be implemented as an alternative. For Parts 1 and 2a of this feature, a standalone air purifier with carbon filter and HEPA filter performing equivalent to MERV 17-20 may be used in accordance with manufacturer’s guidelines. Installation of the HEPA filters may not be conditional based on the criteria in Part 2b. A sufficient quantity of stand-alone air purifiers and carbon filters and HEPA filters must be provided in accordance with the manufacturers recommended area coverage. Provide a policy document to confirm Part 3 of this Feature, and a policy document that confirms that the project owner will maintain and replace the filters and filter units located within the project as per manufacturer specifications.
Projects unable to provide additional space for carbon filters may instead educate future tenants on their ability to buy and install stand-alone air purifiers with carbon filters. The project team must provide a letter signed by the project owner to confirm that if required for WELL certification in the future, the project owner will buy and install the air purifiers with filters on behalf of the tenant. It must be demonstrated that adequate wall space is accommodated to install wall-mounted air purifiers. The WELL Performance Testing Agent will confirm the available wall space and examine a copy of all the information given to tenants during the project’s Performance Verification.
Add "or combination particle/carbon filters." to the end of Part 1a. Part 1a now reads "Rack space and fan capacity is in place for future carbon filters or combination particle/carbon filters."
Change Part 1b from "The system is able to accommodate additional filters" to "The mechanical system is sized to accommodate the additional filters."
Class F 7 (or higher) media filters are an acceptable equivalent to MERV 13 (or higher) media filters.
In lieu of installing rack space for future carbon filters, an execution plan for future modifications to the HVAC system to create rack space for carbon filters may be provided in the event that the installation of carbon filters is a requirement of the WELL Building Standard in the future. To follow this approach, it must be confirmed that the system would be able to physically accept carbon filters should the necessary rack space be created, the plan must identify the cost estimates of renovating the HVAC system to include the necessary rack space to confirm that it is considered a capital improvement item, and the owner must commit to making the upgrades should the WELL Building Standard require carbon filters in a future recertification of the project.
Multifamily Residential projects may use wall-mounted HEPA filters to meet the requirements of Feature 5 Parts 1 and 2, provided the project contains a sufficient quantity of wall mounted HEPA filters in accordance with the manufacturer’s recommended area coverage. In addition, a policy document must be provided confirming Part 3 of the Feature and that the Owner will maintain the filters for the units that are located in both common and private areas.
Feature 6: Microbe and mold control
Post Date: 17 Jan, 2017
As an alternative to the quarterly inspection of cooling coils required in Feature 6, Part 1b, projects may sample 25% of the project’s cooling coils per quarter (representative of all building orientations and equal to 100% of cooling coils per year) through either visual inspection or performance inspection tests. Policy documentation must be provided that includes a detailed description of the inspection protocols for cooling coils and drain pans, and confirming that cleaning will be provided if mold is found before the annual inspection. The inspection and analyses must be performed in accordance with ISO 16000-18 and ISO 16000-17.
Note that dated photos must still be provided to IWBI on a yearly basis.
'Intent: To reduce mold and bacteria growth within buildings, particularly from water damage or condensation on cooling coils.'
Add annotated operations schedule OR MEP drawing as required documentation, remove MEP Letter of Assurance, remove on-site spot checks.
Feature 7: Construction pollution management
Add: "newly installed" after "all"
Add: "occurring within one year prior to Performance Verification" after "building construction"
Add: "occurring within one year prior to Performance Verification" after "during construction"
'Intent: To minimize the introduction of construction-related pollutants into indoor air and protect building products from degradation.'
Change title of Part 3 from "VOC Absorption Management" to "Moisture Absorption Management"
In Part 3, change "To prevent building materials from absorbing and later releasing VOCs emitted by other (source) materials during construction, the following requirements are met: to "To prevent building materials from absorbing water or moisture during construction, the following requirements are met:"
In Part 3a, change “A secure area is designated to store and protect…” to “A separate area is designated to store and protect…”.
Remove Parts 3b and 3c.
Inquiry: My project is an existing project; does Feature 7 apply to my project?
Ruling: For existing projects, it must be demonstrated that the requirements of Feature 7 were met for all construction/renovation/alteration activity that took place during the process of readying the project for WELL certification and all construction/renovation/alteration activity that occurred within 1 year prior to the WELL project registration. If no such activity took place within 1 year prior to the WELL project registration, the feature requirements are met.

Post Date: 31 Jul, 2019
c. Any other mMaterial manufactured as an entryway walk-off system, at least the width of the entrance and 3 m [10 ft] long in the primary direction of travel (sum of indoor and outdoor length).
Feature 8: Healthy entrance
Projects may achieve Feature 08, Part 1 by developing and using a comprehensive floor cleaning plan at entrances which details the cleaning products and equipment that will be used to clean various surfaces on a daily basis.
In addition to original documentation requirements, project teams submit a professional narrative which specifies cleaning products and equipment, protocols for post-inclement weather situations and a checklist with daily tasks that are completed at least two times per day.
This option is applicable only for buildings whose entrance lobby is not a regularly occupied space or to projects where the building entrance is outside the project boundary.
Post Date: 01 Nov, 2018
In 24 Oct, 2016 AAP, remove: "Where projects are restricted from using an entry vestibule or revolving door (for e.g. projects in the Philippines following the National Building Code, which prohibits revolving doors or vestibules for designated exits), they". Add: "Projects"
In 24 Oct, 2016 AAP, remove: "Where the options of an entry vestibule or revolving door are not possible for projects with regularly occupied lobbies, projects". Add: "Projects"
In part description, add: ", including doors with pedestrian traffic only to/from terraces or patios (no traffic to/from surrounding grounds), " after "…occupant shoes at all regularly used entrance(s)"
In 24 Oct, 2016 AAP, remove: ""Projects must also provide indoor pressure sensor readings from one day. This should include exhaust and supply sequences. Projects should also provide mechanical drawings of the project space and manufacturer documentation of the air curtain equipment"". Add: ""To document this alternative adherence path, the project team must provide the following in the Documentation Submission:
- Indoor pressure sensor readings in accordance with ANSI/ AMCA 220 including exhaust and supply sequences from a single day
- Mechanical drawings of the project space and manufacturer documentation of the air curtain equipment""
Post Date: 05 Feb, 2018
For Part 3a, remove: "locker room". Add: "changing room"
For Part 1a, add: "(sum of indoor and outdoor length)" after "primary direction of travel"
For Part 1b, add: "(sum of indoor and outdoor length)" after "primary direction of travel"
For Part 1c, add: "(sum of indoor and outdoor length)" after "primary direction of travel"
Remove: "Permanent" from title of Part name.
For projects that have an entryway walk off system that is less than 10 feet in length, but no smaller than 9’6’’, temporary rollout mats may be used during potential inclement weather (i.e. a 30% chance or higher) to bring the walk-off system up to 10 feet in length. In addition, projects must commit to cleaning the entrance/lobby multiple times daily, and demonstrate this through a cleaning plan. Provide the cleaning plan as well as a narrative detailing the project policy regarding rollout mats and inclement weather.
Projects may use a permanent entryway system 3 meters long, and an air curtain to create an air seal. There are several specifications for this path:
The air curtain must have a minimum velocity of not less than 2 meters per second (6.56 feet per second) at the floor, have been tested in accordance with ANSI/AMCA 220, and must be installed in accordance with manufacturer's instructions. It must also be commissioned prior to occupancy by a qualified agent.
An indoor pressure sensor must be installed in the building lobby that is capable of providing automatic readings at least once an hour.
The project team must specify target pressurization levels for these locations when the building is occupied. These levels have to keep air from entering the building more than the standard amount, allow occupants to open and close doors easily and not cause moisture problems due to exfiltration. Projects must provide documentation of these targeted levels and ensure they achieve the objectives outlines above.
To document this alternative adherence path, the project team must provide the following in the Documentation Submission:
Indoor pressure sensor readings in accordance with ANSI/ AMCA 220 including exhaust and supply sequences from a single day
Mechanical drawings of the project space and manufacturer documentation of the air curtain equipment
Projects may create a healthy space by installing stand-alone air filters in the breathing zone near the primary seating of occupants, and near the entrance. A narrative must be included with documentation to describe the contaminants that will be filtered out along with an operations schedule for the maintenance of the air filters.
'Intent: To minimize the introduction of pollutants into indoor air at building entrances.'
The requirements of Part 2 (Entryway Seal) may be met by controlling building pressure according to the following requirements:
- An indoor pressure sensor must be installed in the building lobby and near any other entrance to the building from the outside. The pressure sensor must be capable of providing automatic readings on a frequency of at least one per hour.
- The project team must specify the targeted building pressurization levels for these locations for when the building is in both cooling mode and heating mode. The pressure levels must keep outside air from entering the building (more than standard practice), allow occupants to open and close doors easily, and must not cause undue condensation or other moisture problems due to exfiltration through the building envelope.
To document this alternative path, the project team must provide the following in the documentation application submission:
- A narrative describing the targeted building pressurization levels for both cooling mode and heating mode.
- A narrative (and other supporting documentation as necessary) demonstrating that the pressure levels keep outside air from entering the building (more than standard practice), allow occupants to open and close doors easily, and do not cause undue condensation or other moisture problems due to exfiltration through the building envelope.
- Indoor pressure readings demonstrating one day of pressure sensor readings from a cooling period, and one day of pressure sensor readings from a heating period. The exhaust and supply sequences must be provided to demonstrate that the desired pressure readings will be achieved.
Replace the first sentence with the following: "One of the following is in place to slow the movement of air from outdoors to indoors within mechanically ventilated main building entrances:"
