What is the WELL Building Standard?

The WELL Building Standard is a global framework designed to measure, certify, and monitor building features to promote occupant welfare. Developed by the International WELL Building Institute (IWBI), WELL aims toward sustainability, health, and happiness through comprehensive considerations in design, construction, and operations.

Additionally, the WELL Building Standard focuses on seven core concepts: air, water, nourishment, light, fitness, comfort, and mind. These concepts include strategies to promote indoor quality, physical activity, mental well-being, and occupant health.

Furthermore, WELL Certification entails a rigorous evaluation process to verify buildings meet standard requirements. Consequently, achieving WELL Certification demonstrates a commitment to creating healthy, sustainable, and people-centric environments that prioritize the well-being of occupants.

What are the 7 principles of the WELL Building Standard?

The WELL Building Standard is organized based on seven fundamental principles. These principles tackle different facets of the built environment and their effects on human health and well-being. Within each concept, there are specific features, some mandatory for certification attainment, while others offer opportunities for additional points.

These are the seven concepts of the WELL Building Standard, briefly outlined:

1. Air

This concept focuses on optimizing indoor air quality by controlling pollutants and enhancing ventilation to promote respiratory health and comfort.

2. Water

The water concept emphasizes access to clean and safe drinking water, as well as efficient water management practices to conserve this vital resource.

3. Nourishment

Nourishment addresses healthy eating habits and nutritional choices within the built environment, promoting access to nutritious foods and discouraging the consumption of unhealthy options.

4. Light

This concept aims to maximize access to natural light and minimize exposure to artificial lighting sources, which can positively influence circadian rhythms, mood, and productivity.

5. Fitness

Fitness encourages physical activity and active lifestyles by providing opportunities for exercise, movement, and active transportation within the built environment.

6. Comfort

Comfort focuses on creating indoor environments that are comfortable and conducive to well-being, addressing factors such as thermal comfort, acoustics, and ergonomics.

7. Mind

The mind concept supports mental well-being by promoting stress reduction, cognitive function, and emotional health through strategies such as biophilic design, mindfulness practices, and social connectivity.

The differences between WELL and LEED certifications for sustainable buildings

As the emphasis on healthier and environmentally friendly buildings increases, building owners must grasp the differences between WELL and LEED certifications. This knowledge is crucial for navigating the complexities of sustainable building practices and ensuring projects align with specific certification goals.

By gaining insight into these differences, stakeholders can make informed decisions that contribute to more sustainable and occupant-friendly built environments.

Challenges and opportunities in implementing sustainable practices with WELL Certification

When demand for healthier and environmentally conscious buildings rises, integrating sustainable practices poses numerous challenges and opportunities for facility managers.

This trend highlights the necessity of navigating sustainability complexities while utilizing innovative solutions to improve living standards and environmental performance.



1. Cost and financial constraints

One of the primary challenges of implementing the WELL Building Standard is the upfront cost associated with certification, as well as the ongoing expenses related to maintaining compliance. Building owners may face financial constraints when attempting to invest in features and technologies that support occupant health and well-being, particularly in the absence of clear financial incentives or cost savings.

2. Complexity and technical requirements

Achieving WELL certification requires a thorough understanding of the standard technical requirements and documentation processes. The certification process can be complex, requiring specialized expertise in areas such as indoor air quality, lighting design, and ergonomic considerations. This complexity may pose challenges for project teams, particularly those with limited experience in health-focused building practices.

3. Resistance to change

Implementing the WELL Building Standard may encounter resistance from stakeholders who are accustomed to traditional building practices or who perceive sustainability and wellness initiatives as optional or secondary priorities. Overcoming resistance to change requires effective communication, education, and stakeholder engagement to demonstrate the value and benefits of prioritizing occupant health and well-being in the built environment.

4. Measurement and verification

Ensuring ongoing compliance with the WELL Building Standard requires continuous measurement and verification of building performance, as well as periodic recertification to maintain certification status. This process can be resource-intensive and time-consuming, requiring dedicated monitoring, data collection, and reporting efforts to track progress and address any deviations from compliance requirements.



1. Differentiation and market leadership

Achieving WELL certification provides an opportunity for building owners to differentiate their properties in the marketplace, positioning them as leaders in sustainability and occupant health. Certification can enhance marketability, attract tenants, and command premium rents, especially in sectors where occupant health and well-being are prioritized, such as healthcare, education, and corporate real estate.

2. Tenant and occupant satisfaction

Implementing the WELL Building Standard can lead to higher levels of tenant and occupant satisfaction by providing healthier and more comfortable indoor environments. WELL-certified buildings are more likely to attract and retain tenants, improve employee morale and productivity, and enhance overall occupant experience.

3. Innovation and collaboration

The WELL Building Standard encourages innovation and collaboration among building professionals, manufacturers, and researchers to develop new technologies, materials, and design strategies that support the standard of living. By fostering a culture of innovation and collaboration, the standard drives continuous improvement in building practices and promotes the adoption of cutting-edge solutions that benefit both people and the planet.

4. Health and wellness outcomes

Ultimately, the primary opportunity presented by the WELL Building Standard is the potential to improve health and wellness outcomes for building occupants. By prioritizing features that enhance indoor environmental quality, promote physical activity, support mental well-being, and encourage healthy behaviors, the standard positively impacts millions worldwide, fostering healthier communities.

In conclusion, as the demand for healthier and more environmentally conscious buildings continues to grow, the principles and standards established by the WELL Building Standard will undoubtedly play a pivotal role in shaping the future of sustainable development. By prioritizing occupant health and happiness alongside environmental sustainability, the WELL Standard not only raises building design, construction, and operation but also fosters healthier, more resilient communities.

Furthermore, the WELL Building Standard serves as a driving force behind innovation in sustainable building practices. Through ongoing collaboration, innovation, and commitment to improving the built environment, stakeholders can further advance the adoption of health-focused, environmentally sustainable practices, ultimately creating spaces that promote well-being for future generations.
