Authentic WELL Certification Exam WELL-AP Questions Answers

For WELL Certification air quality thresholds, particulate matter (PM2.5) levels are a common concern due to their impact on respiratory and cardiovascular health. A result showing PM2.5 equal to 10 µg/m³ would likely meet the stringent air quality requirements set by WELL standards for indoor environments. This level indicates good air quality management practices, such as effective air filtration and ventilation systems, contributing to a healthy indoor environment.

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.

VOCs are organic chemicals that can evaporate or vaporize into the air at room temperature. They can be emitted from various sources such as building materials, furnishings, paints, cleaning products, personal care products, tobacco smoke, and combustion appliances. Exposure to VOCs can cause irritation of the eyes, nose, and throat, headaches, nausea, dizziness, and respiratory problems. Some VOCs are also known or suspected carcinogens. According to the WELL v2 standard, reducing indoor VOC concentrations can improve respiratory health and well-being12.
