The WELL Building Standard is the premier standard for buildings, interior spaces and communities seeking to implement, validate and measure features that support and advance human health and wellness.

WELL was developed by integrating scientific and medical research and literature on environmental health, behavioral factors, health outcomes and demographic risk factors that affect health with leading practices in building design, construction and management.

The evolution of WELL v2 was supported by more than 150 WELL concept advisors. Concept advisors have expertise in one or more of the ten WELL concepts and provide input on solutions to health and wellness concerns, best practices for localization, case studies to fill research gaps and innovative topic areas.

There are ten concepts in WELL v2, each concept consists of features with distinct health intents:

The WELL Air concept aims to achieve high levels of indoor air quality across a building’s lifetime through diverse strategies that include source elimination or reduction, active and passive building design and operation strategies and human behavior interventions.

The WELL Water concept covers aspects of the quality, distribution and control of liquid water in a building. It includes features that address the availability and contaminant thresholds of drinking water, as well as features targeting the management of water to avoid damage to building materials and environmental conditions.

The WELL Nourishment concept requires the availability of fruits and vegetables and nutritional transparency. It encourages the creation of food environments, where the healthiest choice is the easiest choice.

The WELL Light concept promotes exposure to light and aims to create lighting environments that promote visual, mental and biological health.

The WELL Movement concept promotes physical activity in everyday life through environmental design, policies and programs to ensure that movement opportunities are integrated into the fabric of our culture, buildings and communities.

The WELL Thermal Comfort concept aims to promote human productivity and provide a maximum level of thermal comfort among all building users through improved HVAC system design and control and by meeting individual thermal preferences.

The WELL Sound concept aims to bolster occupant health and well-being through the identification and mitigation of acoustical comfort parameters that shape occupant experiences in the built environment.

The WELL Materials concept aims to reduce human exposure, whether direct or through environmental contamination, to chemicals that may impact health during the construction, remodeling, furnishing and operation of buildings.

The WELL Mind concept promotes mental health through policy, program and design strategies that seek to address the diverse factors that influence cognitive and emotional well-being.

The WELL Community concept aims to support access to essential healthcare, build a culture of health that accommodates diverse population needs and establish an inclusive, engaged occupant community.
