Sample WELL AP Practice Questions

Try these sample questions to review concepts for the WELL AP exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 136+ question experience with AI tutoring.

1What is the primary focus of the WELL Building Standard?
A.Energy efficiency and carbon reduction
B.Human health and wellness in buildings
C.Structural engineering and seismic safety
D.Fire protection and egress design
Explanation: The WELL Building Standard focuses specifically on human health and wellness in the built environment. Unlike LEED which addresses environmental sustainability broadly, WELL targets how buildings affect occupant health through features like air quality, water quality, lighting, and mental wellbeing.
2How many concepts are included in the WELL v2 standard?
A.7
B.8
C.10
D.12
Explanation: WELL v2 includes 10 concepts: Air, Water, Nourishment, Light, Movement, Thermal Comfort, Sound, Materials, Mind, and Community. Each concept addresses a different aspect of human health and wellbeing in buildings.
3Which organization administers the WELL AP credential?
A.USGBC
B.ASHRAE
C.IWBI / GBCI
D.EPA
Explanation: The WELL AP credential is administered by IWBI (International WELL Building Institute) with exam delivery through GBCI (Green Business Certification Inc.). IWBI developed the WELL Building Standard, and GBCI handles the credentialing and certification process.
4What is the minimum ventilation rate increase required by the WELL Air concept's Enhanced Ventilation feature?
A.10% above ASHRAE 62.1
B.30% above ASHRAE 62.1
C.50% above ASHRAE 62.1
D.100% above ASHRAE 62.1
Explanation: The WELL Air concept's Enhanced Ventilation feature requires a minimum 30% increase in outdoor air supply rates above the ASHRAE 62.1 baseline. This increased ventilation helps dilute indoor pollutants and improve occupant health outcomes.
5Which WELL concept addresses access to fruits, vegetables, and whole grains in the workplace?
A.Community
B.Mind
C.Nourishment
D.Movement
Explanation: The Nourishment concept addresses food access, nutrition, and healthy eating patterns in buildings. It includes features related to fruit and vegetable availability, nutritional transparency, food advertising restrictions, and mindful eating spaces.
6What does the WELL Light concept primarily aim to optimize?
A.Reducing electricity consumption from lighting
B.Supporting circadian health and visual acuity
C.Maximizing natural daylighting for LEED credits
D.Preventing glare on computer screens only
Explanation: The WELL Light concept focuses on optimizing both circadian health and visual acuity. It addresses melanopic lighting for circadian rhythm support, visual lighting design for task performance, glare control, and access to daylight — all prioritizing human health outcomes over energy efficiency.
7Which metric does WELL use to measure the biological effect of light on circadian rhythms?
A.Foot-candles (fc)
B.Lumens per watt (lm/W)
C.Equivalent Melanopic Lux (EML)
D.Color Rendering Index (CRI)
Explanation: WELL uses Equivalent Melanopic Lux (EML) to measure light's biological impact on circadian rhythms. EML accounts for the sensitivity of melanopsin-containing retinal ganglion cells, which are key to regulating the body's circadian clock, unlike traditional photometric measures like foot-candles.
8What is the maximum PM2.5 threshold that WELL requires for indoor air quality?
A.15 µg/m³
B.25 µg/m³
C.35 µg/m³
D.50 µg/m³
Explanation: WELL sets a stringent indoor PM2.5 threshold of 15 µg/m³, which is more restrictive than many national ambient air quality standards. PM2.5 particles are a major concern because they can penetrate deep into the lungs and enter the bloodstream, causing cardiovascular and respiratory issues.
9Which WELL feature requires projects to provide sit-stand desks or active workstations?
A.Active Furnishings
B.Ergonomic Seating
C.Physical Activity Spaces
D.Movement Network
Explanation: The Active Furnishings feature under the Movement concept requires projects to provide sit-stand desks, active workstations, or other furnishings that promote physical movement during the workday. This addresses the health risks associated with prolonged sitting.
10What certification levels are available under WELL v2?
A.Certified and Platinum only
B.Bronze, Silver, Gold, Platinum
C.Silver, Gold, Platinum
D.Certified, Silver, Gold, Platinum, and WELL Core
Explanation: WELL v2 offers four certification levels: Bronze, Silver, Gold, and Platinum. Each level requires achieving a certain number of points across the 10 concepts. Projects must meet all preconditions and earn additional optimization points to achieve higher levels.
