Three certifications drive most commercial indoor-air decisions in North America. Each evaluates buildings against different rubrics. WELL (International WELL Building Institute) scores health outcomes broadly: air, water, nourishment, light, movement, thermal comfort, sound, mind, community. Air is one of ten concepts; within it are 12 features ranging from ventilation effectiveness to particle filtration to source control.
RESET is data-driven where WELL is design-driven. RESET requires continuous monitoring of PM2.5, CO2, TVOC, T, and RH, with public data reporting. The certification renews based on actual measured air, not on installed equipment. For tenants leasing space, "RESET Air Certified" means measurable, ongoing performance, not a one-time inspection.
LEED (U.S. Green Building Council) is the broadest of the three: a sustainability framework where indoor environmental quality is one credit category. LEED rewards design choices (low-VOC materials, MERV-13 minimum filtration, demand-controlled ventilation) at the construction/commissioning stage. Once a building is LEED certified, the certification doesn't require ongoing IAQ measurement.
For commercial deployments of Terrestream, the data the sensor collects can directly feed RESET reporting requirements, support WELL Air feature documentation, and provide the verification data LEED-certified buildings need for EQ credits in operations-and-maintenance recertification. The dashboard's building view summarizes the sensors against any of the three frameworks on request.
