To achieve an acceptable thermal environment for building occupants, the WELL AP should suggest designing mechanically conditioned regularly occupied spaces to maintain thermal comfort conditions with a Predicted Mean Vote (PMV) of +/- 0.5 for at least 90% of the occupied hours. This approach aligns with WELL's requirements for thermal comfort, focusing on creating indoor environments that are comfortable for the majority of occupants. By maintaining these conditions, the design supports occupant health, well-being, and productivity, while addressing one of the strongest contributing factors to overall satisfaction in the built environment.
