The production of polychlorinated biphenyls (PCBs) has been widely restricted, as they are

  1. biocides that can leach into the environment
  2. carcinogens that bioaccumulate in the environment
  3. total dissolved solids that accumulate in the environment
  4. volatile organic compounds that off-gas into the environment

Answer(s): B

Explanation:

Polychlorinated biphenyls (PCBs) are carcinogens that bioaccumulate in the environment. PCBs are a group of synthetic organic chemicals that were widely used in electrical equipment, paints, plastics, and other industrial products until their production was banned or restricted in many countries in the late 1970s and early 1980s. PCBs are persistent, meaning they do not break down easily in the environment, and bioaccumulative, meaning they build up in the fatty tissues of animals and humans. Exposure to PCBs can cause various adverse health effects, such as cancer, liver damage, immune system impairment, reproductive and developmental disorders, and neurobehavioral effects12.

A project in a defined WELL Portfolio achieved all 24 preconditions and 60 points through optimizations. How many total points can this project contribute toward the WELL Portfolio Score?

  1. 24 points
  2. 42 points
  3. 60 points
  4. 84 points

Answer(s): C

Explanation:

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
Rationale Behind the Answer
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.
Importance in Context
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.
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.



Which of the following strategies can be used to improve the visual balance in a workspace?

  1. Vary the color temperatures of light fixtures within the room
  2. Increase the horizontal and vertical luminance contrast ratios to 15
  3. Replace magnetic ballasts on fluorescent lights with electronic ones
  4. Increase the illuminance uniformity ratio to at least 0.4 on the work surface

Answer(s): D

Explanation:

For visual balance in a workspace, ensuring an illuminance uniformity ratio of at least 0.4 on any horizontal task plane within a space is essential. This requirement helps in creating a visually comfortable environment by reducing fluctuations in light levels that can lead to eye fatigue and visual discomfort.



Supplemental light fixtures are provided to occupants upon request at no cost within a WELL

building. This benefit will enhance occupant comfort by

  1. providing visual diversity
  2. improving correlated color temperature
  3. keeping lighting uniformity in the space
  4. increasing the light level on the task surface

Answer(s): D

Explanation:

Supplemental light fixtures, such as task lights, are provided to occupants upon request at no cost within a WELL building to enhance occupant comfort by increasing the light level on the task surface. This benefit allows occupants to adjust their local lighting conditions according to their individual preferences and needs, which can improve their visual acuity, productivity, and satisfaction. Feature L09 requires projects to provide supplemental light fixtures that meet certain criteria for illuminance, color quality, and glare control.

A well-being team in a commercial office building is interested in starting a garden. Twenty of the 400 employees are interested in starting an herb and vegetable garden. A minimum of how much space is required for the garden to earn an Optimization in the WELL Building StandardTM (WELLTM)?

  1. 20 ft2 (2 m2)
  2. 200 ft2 (18 m2)
  3. 400 ft2 (36 m2)
  4. 600 ft2 (56 m2)

Answer(s): B

Explanation:

According to the WELL v2TM feature N12 Optimization Food Production, a permanent and accessible space for food production is required to be at least 1 ft2 per regular occupant or 0.5 ft2 per student, whichever area is greater (up to a maximum of 1,500 ft2 and not less than 200 ft2). The area calculated is the actual growing area (vertical or horizontal) used for the production of food-bearing plants. For a commercial office building with 400 regular occupants, the minimum space required is 200 ft2.
