International Well Building Institute


Managed by the International WELL Building Institute, it is similar to the LEED Certification in its conception. Also of American origin, and the result of more than 7 years of study, it includes, in a holistic way, both the physical factors of the work environment and the company policies to conceive a set that ensures the well-being and health of the users. It has 10 areas:

  • Air: elimination of air pollutants, prevention of pollution and purification of the air.
  • Water: filtration, treatment and strategic location of water points.
  • Food: establishment of healthy food options and promotion of a healthy diet.
  • Light: access to natural light and improvement of the quality of artificial light.
  • Movement: promotion and incorporation of activities that allow users to lead an active life.
  • Thermal Comfort: adaptation of the space to maximize thermal comfort.
  • Sound: adaptation of the space to maximize acoustic comfort.
  • Materials: Reduce people’s exposure to the polluting components of materials.
  • Mind: establishing company policies that contribute to reducing stress and improving the mental and emotional well-being of workers.
  • Community: Inclusive and integrated design through social considerations, civic engagement and accessible design.
