WELL Building Standard® Commercial Kitchen Pilot A The WELL Pilot Program The WELL Building Standard® Version 1.0 (WELL v1.0) was launched on October 20th, 2014 for the Commercial and Institutional Office building sector. That standard applies to office spaces, where well-being is related to worker health, performance and motivation.

While positioned for office projects, large sections of the WELL Building Standard have applications outside the office setting, although most building types require some modification. These differences create the need for new WELL Pilot Programs. As such, the International WELL Building Institute™ (IWBI) has begun creating Pilot Programs to test and refine how standards can best apply to new building sectors. The IWBI will integrate the information and lessons learned from the WELL Pilot Program into future versions of the WELL Building Standard, which will include specific Features, Parts, and Requirements for new building sectors addressed by the pilots.

WELL Pilot Standards are developed by incorporating best practices for building design and by adapting the current WELL Building Standard to new building uses. Over the course of a Pilot Program, the IWBI will use information and feedback gathered from pilot projects and industry experts to further refine the Pilot Standard prior to publication as part of the WELL Building Standard. A standard will move out of the pilot phase and become a graduated standard, which refers to standards that are integrated into the base WELL Building Standard. Graduated standards, by definition, are standards that have successfully passed through pilot testing and are part of the published WELL Building Standard.

Certification of Pilots Pilots may receive Silver, Gold or Platinum Pilot Certification.

To achieve Silver Pilot Certification, a project must satisfy 100% of all Preconditions as well as 20% of all Optimizations. This differs from the WELL Building Standard due to the fact that the IWBI uses feedback including which Features are selected as a basis for informing the eventual integration of pilot Features into the WELL Building Standard.

Gold and Platinum Pilot Certification follow the same rules as with the WELL Building Standard: 100% of all Preconditions must be met plus 40% of all Optimizations for Gold Pilot Certification or 80% of all Optimizations for Platinum Pilot Certification.

WELL Pilot Certification is not guaranteed and will not be awarded until the IWBI verifies that all necessary documentation and performance requirements are met.

Organization of Spaces A space is defined as some or all of a building that is typified by a specific use or function. Spaces are tied to specific WELL standards and can either be primary or secondary, as designated by the IWBI. All projects are anchored by a primary space and follow its associated WELL standard. If the scope of a pilot project includes a space that falls under the definition of an existing secondary space, then that project must apply the secondary space standard alongside the primary space standard for WELL Pilot Certification.

This pairing system ensures that any distinct spaces within the project scope that may require unique considerations will only be held to those requirements appropriate for that space. However, pairing standards is required only when the WELL standards associated with the spaces are both of the same

3


class: either both the standards are pilot standards, or both the standards are graduated (i.e., non-pilot) standards. For more information, see the WELL Certification Guidebook for Pilot Projects.

In line with the above, once the Commercial Kitchen Pilot concludes its pilot phase and graduates into the WELL Building Standard, projects currently pursuing WELL for Commercial and Institutional spaces that include a kitchen component that fits the definition of a Commercial Kitchen secondary space provided herein will be required to pursue the Commercial Kitchen Standard for their space.

Commercial Kitchen Spaces Commercial Kitchen spaces are secondary spaces in the scope of the WELL Building Standard®. This means that the Commercial Kitchen Pilot Standard cannot be applied across the entirety of a certified project: this standard can only be applied to a portion of the project. Therefore, the Commercial Kitchen space’s standard must always be paired with at least one primary space standard, with its own associated set of Features that together constitute a project eligible for WELL Pilot Certification. For example, a restaurant may involve the use of the Commercial Kitchen Pilot Standard to cover the kitchen component, while the dining area component of the space would adhere to the Restaurant Pilot Standard.

This Pilot Standard for Commercial Kitchens presents new content designed to provide improvements to the facilities, equipment and area that support the needs of the cooks, servers and other restaurant staff. Of particular focus are Features intended to promote proper ventilation and sanitation in food preparation areas.

The Commercial Kitchen space is applicable in locations where dedicated staff are employed to prepare and serve food to other building occupants, meaning that food preparation activities occur on the site. It is not applicable to office kitchenettes or home kitchens. In general, those spaces subject to local health inspection are likely to use this Pilot Standard.

The Commercial Kitchen Pilot Standard has a very specific scope: it covers only the physical conditions within the kitchen itself and relating to the preparation of food. Food preparation is defined strictly as those functions related to preparing foods and the spaces and tools used for this task, not including food purchasing decisions, how meals are presented or distributed, or greater policy-related decisions regarding the types of meals served by the institution.

As such, Fitness Features and Mind Features regarding employee policy are absent from the Commercial Kitchen Pilot Standard. These Features are instead covered in the standard component to which the kitchen will be paired (e.g., Restaurant or Commercial and Institutional Office).

Participating in the Pilot Program The first step in creating a commercial kitchen pilot project is to officially apply to the Pilot Program with the IWBI. Projects must provide specific information to the IWBI for initial evaluation. The IWBI will conduct an initial evaluation to ensure the project is appropriately categorized as a WELL Commercial Kitchen Pilot Project, and if so, the IWBI will assign an agent to work closely with the project’s designated point of contact to provide assistance and ensure that feedback can be carefully integrated into the pilot framework.

The goal of the WELL Pilot Program is to garner substantive feedback on elements outside the core of the WELL Building Standard®. One benefit of registering as an early pilot is that the project will work with the assigned agent and the IWBI to establish guidelines and evaluate new Features and Parts for future inclusion into the published WELL Building Standard.

How to Use Addenda with the current WELL Building Standard This document presents the Pilot Standard as an addendum: a concise supplementary document that makes clear how the current version of the WELL Building Standard uniquely applies to the building sector. Projects can thus use the current version of the WELL Building Standard as the primary resource and set of requirements along with the WELL Certification Guidebook for Pilot Projects, which clarifies how proof of achievement is verified.

This addendum document describes the three differences between the pilot and the WELL Building Standard:

1. Parts that do not apply in any form to this pilot.2. New Parts within existing Features that apply to this pilot.3. New Features that apply to this pilot.

If an applicable Feature does not fall into the categories above, then the pilot project should follow the Feature as described in the current version of the WELL Building Standard.

The following chart summarizes numbers 1 and 2 above by listing the existing applicable Parts, the existing not applicable Parts, and the new Parts. It also describes the Feature level (Precondition/Optimization) for this pilot, which may be different than in the published WELL Building Standard.

PILOT FEATURES

As part of the pilot project, IWBI is developing Features specific to pilot applications not present in commercial

and institutional projects. Pilot Features are likely to undergo the most change through the pilot process – with

new features added over the life of the project (some potentially proposed by the project itself) and some

changed as project realities influence development.

Pilot Features always carry a designation P followed by a number and are numbered outside of the graduated

WELL numbering system, regardless of their category. Because of simultaneous pilot programs in multiple

building sectors, the numbering system may not be sequential.
