As buildings worldwide strive to achieve green building certifications such as LEED (Leadership in Energy and Environmental Design), WELL Building Standard, and others, the demand for IAQ meters has surged.

  Green buildings integrate IAQ meters as essential components of their indoor environmental monitoring systems. These meters play a crucial role in measuring and maintaining optimal indoor air quality parameters such as levels of particulate matter (PM), volatile organic compounds (VOCs), carbon dioxide (CO2), and humidity. By continuously monitoring IAQ, building managers can identify potential sources of indoor pollutants, implement corrective actions, and ensure compliance with stringent IAQ standards required for green building certification.

  The increasing regulatory support and incentives for green building initiatives further propel the demand for IAQ meters. Governments worldwide are introducing policies and incentives to promote sustainable building practices and improve indoor environmental quality. IAQ meters play a pivotal role in helping buildings meet these regulatory requirements and achieve certification, thereby boosting market growth.

Restraints
