What is the maximum credit available for IAQ Thermal Comfort on all projects?

The maximum credit available for Indoor Air Quality (IAQ) Thermal Comfort in LEED V4 is indeed one credit. This credit focuses on ensuring that thermal comfort is achieved in occupied spaces through appropriate design, verification, and post-occupancy evaluation of the indoor environment.

Thermal comfort is critical because it directly affects occupant satisfaction, productivity, and well-being. By recognizing that only one credit can be awarded for this particular aspect, LEED emphasizes the importance of a comprehensive approach to achieving thermal comfort, rather than allowing multiple credits for similar strategies or measures. This streamlined approach encourages projects to implement effective thermal comfort strategies without providing redundant credit opportunities.

While there are other related credits in the IAQ category, such as those for ventilation, low-emitting materials, and indoor air quality management during the construction phase, the specific credit for thermal comfort is capped at one to maintain a clear focus on this essential aspect of sustainable design and occupant health.
