Based on the information provided, the most relevant WELL feature to consider for Bay Towers by Bayleaf, given its location and amenities, is Feature M02: Nature and Place. This feature focuses on supporting occupant well-being by integrating the natural environment throughout the project and celebrating the project ' s unique identity, which aligns with the building ' s connection to Elliot Bay and the riverfront park via a pedestrian bridge. However, without explicit details on the implementation of nature throughout the project or specific design strategies, it ' s challenging to confirm compliance with this feature fully. Therefore, a conservative estimate would be that the project could potentially earn at least one point from this feature, assuming some level of nature integration and celebration of the unique location is achieved in the renovation and operation plans​​.

According to Feature A09: Pollution Infiltration Management, part 3 of the WELL Core requirements, the project team must install self-closing doors between high- humidity spaces (such as kitchens, bathrooms, and laundry rooms) and regularly occupied spaces 1 . This helps prevent the spread of moisture and odors that can affect indoor air quality and comfort 2 .

This answer best meets the requirements of Feature C01, which aims to promote a deeper occupant understanding of the WELL features pursued by the project or organization and how building design, operations and policies impact health and well-being. A multi-modal strategy that includes a WELL feature guide and regular communication can help reinforce the project’s culture of health, market health promotion policies and programs, and offer education on topics within the ten WELL concepts.

WELL AP Study Guide

Focus on WELL Core:  The question is specifically about WELL Core preconditions, which apply to the building owner/operator (Bayleaf), not individual tenants.

WELL v2 Precondition - V02 Part 1 (Ergonomic Workstation Design):  Requires adjustable-height workstations for at least 25% of all workstations.

Calculation:  Bayleaf manages the building and has 2 employees with desks - a receptionist and a property manager. 25% of 2 workstations is 0.5. Rounding up per WELL guidelines, at least 1 workstation should be height-adjustable. Since two people work within Bayleaf itself, both of their workstations need to be height-adjustable to meet the requirement.

The WELL Building Standard outlines specific steps for achieving certification, including a crucial performance verification phase. In this scenario, the most appropriate next step is to proceed with performance verification since:

Occupancy Threshold:  WELL allows performance verification to commence once a building reaches 40% occupancy. In this case, with 650 employees in place, the building has likely exceeded this threshold.

Data Collection:  Starting performance verification early allows for the collection of crucial data regarding air quality, water quality, acoustics, etc. Analyzing this data helps confirm the building is performing as intended and may identify areas for improvement.

Certification Timeline:  Completing performance verification sooner supports a more efficient certification process. It allows for the identification and addressing of any potential issues before submitting final documentation.

Here ' s the breakdown of how to calculate the project ' s contribution to the WELL Portfolio Score:

Preconditions:  While mandatory for certification, preconditions don ' t contribute directly to points for the WELL Portfolio Score.

Optimizations:  Each earned optimization point directly counts towards the overall score. In this case, the project achieved 60 optimization points.

WELL Portfolio Score:  The Score is calculated by aggregating optimization points from all participating projects within the portfolio.

In the WELL Portfolio, the scoring system is based on the performance of individual projects within the portfolio across the various WELL features. Preconditions are the mandatory elements that must be met for certification, but they do not contribute to the total points score. It is the optimizations—optional enhancements beyond the preconditions—that contribute to the scoring. Given that the project has achieved all 24 preconditions and 60 points through optimizations, the total points it can contribute toward the WELL Portfolio Score would be:

C. 60 points

Preconditions and Optimizations: In the WELL system, preconditions are required for all levels of certification and serve as the foundation of WELL Certification. However, they do not count towards the points score. The points score is determined solely by optimizations.

Total Points Contribution: Since the project has achieved 60 points through optimizations, these are the points that contribute to the WELL Portfolio Score, representing the project ' s advancements beyond the foundational preconditions.

Portfolio Scoring Impact: The WELL Portfolio Score is an aggregate measure of performance across all projects within the portfolio. The optimizations that earn points reflect the degree to which each project exceeds the basic WELL requirements, thus pushing the overall portfolio towards higher levels of health and wellness.

Encouraging Excellence: By focusing on optimizations for scoring, WELL encourages project teams to go above and beyond the baseline requirements, fostering innovation and continuous improvement in building design and operations.

Rationale Behind the Answer Importance in Context In conclusion, the 60 points from optimizations directly reflect the project ' s contribution to the advancement of health and wellness within the WELL Portfolio, highlighting the project ' s commitment to exceeding baseline WELL standards.

Increasing the grade of media filter can help reduce the concentration of particulate matter (PM) in the indoor air by capturing more fine particles. According to Feature A12: Air Filtration of WELL v2, projects should use filters with a minimum efficiency reporting value (MERV) of 13 or higher, or equivalent, for mechanical ventilation systems that supply air to occupiable spaces. This can help meet the PM 2.5 threshold of 15 µg/m3 or lower for Feature A01: Air Quality.

Turbidity is a measure of how clear or cloudy water is. It is caused by suspended particles, such as dirt, sand, algae, bacteria, or organic matter, that scatter light and reduce water transparency 3 . Turbidity can affect the color, taste, odor, and safety of drinking water. High turbidity levels can indicate the presence of harmful contaminants, such as pathogens, heavy metals, or pesticides, that can cause health problems 2 . Therefore, the water should be tested for turbidity to determine the cause and extent of the cloudiness and take appropriate actions to improve the water quality.

Feature Z01 requires projects to submit documentation and verification of their WELL performance every three years through the WELL digital platform. This ensures that the project maintains its WELL certification and continues to meet the WELL standards. The WELL AP should develop a schedule with the project owner to collect the right information on an ongoing basis and submit it every three years through the WELL digital platform. The other options are not consistent with the WELL v2 requirements.

According to the WELL v2™ feature V04 Optimization Facilities for Active Occupants, the project must provide no-cost bike parking in the following quantities: Short-term bike parking (e.g., public bike rack) is located within a 100 ft walk distance of a functional building entrance and can accommodate at least 2.5% of peak visitors (minimum of four spaces per building). Long-term bike parking (e.g., bike room) is available within the project boundary and can accommodate at least 5% of regular occupants, excluding occupants under eight years old (minimum of four spaces per building) 1 . Therefore, option D is the correct answer, as it meets the requirement for short-term bike parking. Option A is incorrect, as the bike network must connect riders to at least 10 use types, not five 1 . Option B is incorrect, as long-term bike parking must accommodate at least 5% of regular occupants, not peak visitors 1 . Option C is incorrect, as the project’s address must achieve a minimum Bike Score® of 50, not 40 1 .
