32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- WELL v2 certification tiers
- WELL v2 awards certification at Bronze (40 points), Silver (50), Gold (60), and Platinum (80) after all preconditions are met and verification is complete.
- Preconditions vs. Optimizations
- Preconditions are mandatory requirements that must be satisfied for any certification; Optimizations are optional features that earn points toward a certification tier.
- WELL performance verification
- An on-site assessment by a WELL Assessor that confirms documented claims through inspection and spot testing before certification is granted.
- WELL AP credential
- A professional credential for individuals demonstrating knowledge of the WELL Building Standard, earned by exam and maintained through continuing education.
- MERV 13 filtration
- A filter rating that captures a substantial fraction of fine particles including PM2.5; commonly specified to improve indoor air quality in WELL projects.
- CO2 as ventilation proxy
- Indoor carbon dioxide concentration indicates whether outdoor air ventilation is adequate; outdoor levels are about 400-420 ppm.
- PM2.5 and PM10
- Particulate matter with aerodynamic diameters of 2.5 and 10 micrometers or less; fine particles penetrate deep into the respiratory system.
- TVOC sensor limitations
- Total VOC sensors report a summed, non-specific signal and cannot identify individual compounds, so they are used for trend monitoring.
- Lead in drinking water
- Lead enters water mainly through corrosion of pipes and solder; corrosion control by adjusting pH and alkalinity is the primary mitigation.
- Legionella temperature control
- Maintaining hot water storage above about 60 C and delivery above 50 C, plus eliminating dead legs, reduces Legionella growth risk.
- First-draw water sampling
- Collecting water before flushing captures contaminants that accumulate during stagnation, such as lead from plumbing corrosion.
- Turbidity as water indicator
- A measure of water clarity caused by suspended particles; low turbidity supports effective disinfection and indicates good treatment.
- PMV and PPD
- Predicted Mean Vote estimates thermal sensation on a -3 to +3 scale; Predicted Percentage Dissatisfied estimates the share of uncomfortable occupants.
- Operative temperature
- The combined effect of air temperature and mean radiant temperature, used with humidity, air speed, clothing, and metabolic rate in comfort models.
- Reverberation time RT60
- The time for sound to decay 60 dB after the source stops; excessive RT60 impairs speech privacy and increases listening effort.
- Sound Transmission Class STC
- A single-number rating of how well a partition blocks airborne sound; higher values indicate better isolation between spaces.
- Spatial Daylight Autonomy sDA
- The percentage of occupied floor area meeting a target illuminance from daylight for a specified fraction of occupied hours.
- Melanopic equivalent daylight illuminance
- A metric expressing the circadian-effective light dose on the eye, accounting for spectrum and intensity relevant to entrainment.
- Correlated color temperature CCT
- A measure in kelvin describing the color appearance of a light source; higher values appear cooler and bluer.
- Unified Glare Rating UGR
- A glare metric for interior lighting; lower values indicate less discomfort glare, with values below about 19 often targeted in offices.
- Choice architecture in food
- Designing placement, visibility, and pricing of food options to nudge occupants toward healthier choices without removing options.
- Point-of-decision prompts
- Environmental cues placed at the moment of choice, such as stair-versus-elevator signage, to encourage physical activity.
- Active design strategies
- Building features such as visible stairs, bike storage, showers, and walking paths that integrate physical activity into daily routines.
- Nutritional transparency
- Providing calorie, ingredient, and nutrition information for foods offered in the building so occupants can make informed choices.
- Biophilic design
- Incorporating natural light, views, plants, and natural materials to evoke nature and support stress reduction and wellbeing.
- Occupant satisfaction surveys
- Structured questionnaires used to measure perceived comfort, satisfaction, and wellbeing, informing building operations and verification.
- Environmental stressors indoors
- Noise, thermal discomfort, poor air quality, and lack of environmental control are recognized contributors to occupant stress.
- Lactation room support
- A dedicated, private space for breastfeeding or pumping, supporting occupant health and inclusive workplace policy.
- VOC content vs. emissions
- VOC content measures chemicals in a product formulation; emissions testing measures what is released into indoor air over time.
- CDPH Standard Method 01350
- A chamber-based emissions testing standard used to evaluate building materials for indoor air quality compliance.
- Health Product Declaration
- A transparency document reporting a product's material contents and associated health hazards, supporting informed material selection.
- WELL compliance matrix
- A tracking tool listing each feature part, responsible party, required evidence, and status to manage documentation and verification.
