The “WELL Building Standard” (WELL) was developed to market maturity by the International WELL Building Institute (IWBI). The goal of the procedure is to optimise health in working and living areas; this being at an extent that goes far beyond the specifications of European standards or guidelines.

The system can be used for new buildings, interior furnishings as well as refined shell, designated as “WELL Core”. The valuation takes place based on the following theme fields, designated as “Concepts”:

  • Air
  • Water
  • Nourishment
  • Light
  • Movement
  • Thermal Comfort
  • Sound
  • Materials
  • Mind
  • Community
  • Innovations

The monitoring of the planning is carried out by the so-called “WELL Accredited Professional“ (WELL AP). The confirmation of the assumptions is carried out by an independent “WELL Performance Testing Agent“ (WELL PTA), who carries out comprehensive laboratory analyses of the water and air quality as well as measurements of the room acoustics, building acoustics and light quality (in particular the new theme field Circadian Lighting). Due to the respective licenses, ibak is able to offer both services.
