According to the WELL v2™ feature L02: Visual Lighting Design, the project must provide visual comfort and enhance visual acuity for all users through electric lighting1. One of the design considerations for achieving this is to ensure illuminance uniformity on horizontal task planes, such as desks, tables, or counters, where visual tasks are performed2. Illuminance uniformity is the ratio of the minimum to the average illuminance on a given plane, and it indicates how evenly the light is distributed across the surface3. A high illuminance uniformity can prevent glare, contrast, or shadows that may impair visual comfort and performance4. Option A is incorrect, as CRI ≥ 90 in circulation areas is not a requirement for visual comfort, but rather for electric light quality, which is addressed by feature L081. Option C is incorrect, as luminance ratios on vertical adjacent zones are not a requirement for visual comfort, but rather for visual balance, which is addressed by feature L071. Option D is incorrect, as automatic changes in lighting characteristics over a period of five minutes are not a requirement for visual comfort, but rather for circadian lighting design, which is addressed by feature L031.

In managing spills of hazardous substances like mercury, pesticides, and battery acid, containing all residues in a sealed container is a critical strategy. This approach prevents the spread of hazardous materials, reduces the risk of exposure to building occupants, and facilitates safe and appropriate disposal. It aligns with the WELL Building Standard's emphasis on health and safety, ensuring that the building's waste management plan includes procedures for promptly and effectively dealing with hazardous spills to minimize health risks.

Feature C03: Emergency Preparedness emphasizes planning and preparedness for a range of emergencies. A key element of this is maintaining an inventory of emergency response resources (e.g., first aid, AEDs, etc.) that includes an annual check and update.

For Feature A08: Air Quality Monitoring and Awareness, the WELL Building Standard specifies the minimum density of air quality monitors to ensure adequate coverage and accurate representation of indoor air quality across different spaces. The requirement of one sensor per 3,500 ft² (approximately 325 m²) is designed to provide a balance between comprehensive monitoring and practical implementation. This density allows for sufficient spatial resolution to detect variations in air quality in various areas of a building, facilitating targeted interventions and informing occupants about the air quality in their environment. It reflects WELL's focus on creating environments that support occupants' health and wellbeing by ensuring that air quality, a critical component of indoor environmental quality, is continuously monitored and managed.

Feature T06: Thermal Comfort Monitoring, Part 1: Monitor Thermal Environment in the WELL Building Standard™ focuses on the importance of continuously monitoring key parameters that contribute to thermal comfort in built environments. This feature specifically emphasizes the need to understand and control the thermal conditions that affect occupant comfort and well-being.

Dry-bulb temperature is the measure of air temperature without taking evaporation into consideration. It is one of the most direct indicators of thermal comfort as it affects how warm or cool an indoor environment feels to its occupants.

Relative humidity refers to the amount of moisture in the air compared to what the air can "hold" at that temperature. The level of humidity has a significant impact on how temperatures are perceived by occupants. High humidity can make environments feel stuffier and warmer than the actual air temperature would suggest, while low humidity can make the air feel cooler and dryer.

Feature X09 requires the safe management and minimization of wastes associated with hazardous chemicals present in commonly used products. Protocols for managing and minimizing hazardous waste are a key requirement for this feature.

The key requirement for Feature X09: Waste Management within the WELL Building Standard is to have a waste management plan that includes protocols for managing and minimizing hazardous waste. This plan should cover the identification of roles, responsibilities, vendors for implementing the plan, sources of waste, strategies to minimize waste generation, waste collection strategies, protocols for cleaning spills of hazardous substances like mercury and pesticides, protocols to track, measure, and report waste stream flows, and protocols for off-site shipment of wastes​​.

According to Feature W06 of WELL v2, water dispensers must be cleaned on a daily basis and their mouthpieces, outlets, protective guards, aerators, and basins must be maintained to ensure drinking water quality and hygiene.

The color rendering index (CRI) is a measure of a light source's ability to reveal the colors of various objects faithfully in comparison with a natural light source. Electric lights with a high CRI are effective in improving the perception of space by ensuring that colors are seen more accurately and vibrantly. This can have a significant impact on the aesthetics of the environment, as well as on the well-being and productivity of the occupants, making high CRI lighting a preferred choice in design according to the WELL Building Standard.

For subsequent recertifications after a WELL project's first recertification, the project will be reviewed under the version of the WELL standard that is in place at the time of performance verification. This approach ensures that the project remains up-to-date with the latest WELL standards and practices, reflecting ongoing advancements in building health and wellness. By aligning recertification with the current version of the standard, projects can continuously improve and adapt to new research and methodologies, thereby maintaining a high level of commitment to occupant well-being​​.
