WELL Certification

Francia y Roma original_ 1

The excellence standard focused on people

The WELL certification is the world’s first certification exclusively focused on the health and well-being of building occupants. Unlike other standards, WELL measures how the built environment impacts nutrition, mood, sleep, and human performance.

WELL spaces reduce stress and illness, improving concentration and user satisfaction. For companies, this translates into reduced absenteeism and a stronger organizational culture through a real commitment to human capital.

How does it work?

It is based on real performance auditing. The process includes a technical consulting phase and an on-site verification carried out by external assessors, who measure scientific parameters such as air and water quality to validate that the space truly supports its occupants.

Investment and value

Investment is allocated to technical management, registration, and improvements in wellness systems. Although it involves implementation costs, this translates into a direct return through increased productivity, talent retention, and exclusive differentiation in the corporate real estate market.

Who is it for?

It is aimed at modern corporations, office building owners, commercial developers, and educational institutions. It is ideal for organizations that prioritize employee health and seek to attract talent through healthy and human-centered workplaces.

Requirements and levels

The certification evaluates 10 key concepts: Air, Water, Nourishment, Light, Movement, Thermal Comfort, Sound, Materials, Mind, and Community. Projects can achieve three levels—Silver, Gold, or Platinum—depending on compliance with prerequisites and achieved optimizations.
