The International WELL Building Institute (IWBI) administers the WELL building standard, which is focused exclusively on human health and wellness. IWBI is a US public benefit corporation established by Delos Living LLC, whose stated mission is "to build a better world".
The WELL building standard is third-party certified by GBCI, which administers the LEED program. IWBI and the Building Research Establishment (BRE) are also aligning their WELL and BREEAM standards to make for projects seeking to conform with them.
IWBI aims to transform the indoor environment by placing health and wellness at the center of design and construction decisions.
