Healthy and green buildings rely on good indoor environmental and air quality (IEAQ) to maintain the health and productivity of their occupants. As building envelopes become tighter in favor of energy efficiency, IEAQ can be compromised. Monitoring and managing IEAQ allows building owners to effectively ventilate their buildings. The related technologies also provide measurement and verification (MAndV) of ventilation and moisture management, serving as proof that healthy conditions have been achieved and maintained indoors. While the meaning of good IEAQ has traditionally been restricted to volume of outdoor air circulated in a room, many other technologies improve conditions indoors while lowering ventilation volumes and the energy used to ventilate a building. These technologies include CO2 sensors, demand-controlled ventilation (DCV), energy recovery ventilators (ERVs), dedicated outdoor air systems (DOASs), ultraviolet germicidal irradiation (UVGI), and displacement ventilation (DV), all of which have growing markets. Drivers like regulations and pushback from building occupants will spur building owners to adopt these technologies. According to Navigant Research, the global IEAQ market is expected to grow from $4.2 billion in 2015 to $7.1 billion by 2024. This Navigant Research report analyzes the global market for IEAQ technologies that are currently available and being used in both new construction and retrofit applications. The study provides an analysis of the market conditions for IEAQ monitoring and management and the drivers and barriers for wider adoption of the technologies. Global market forecasts for IEAQ technologies revenue, segmented by region, building type, and technology, extend through 2024. The report also examines the key categories of IEAQ improvements and the related technologies, as well as the competitive landscape.
