Further, the incredibly surging investments to install the HVAC systems is another major factor that is anticipated to accelerate the growth of the global HVAC relay market during the forecast period.
In addition to these, factors that are believed to fuel the market growth of HVAC relay include the rising trend of green buildings on the back of escalating implementation of stringent government regulations associated with energy efficiency and savings, as green buildings utilize less energy and water as compared to conventional buildings. For instance, in 2020, there were more than 128,000 green-rated buildings across the globe. Moreover, an upsurge in industrialization throughout the world is also anticipated to further drive market growth during the forecast period.
Growth Drivers
Growing Ratio of Commercial Construction – A construction is referred to as commercial if no space is used, either permanently or temporarily, for human living. With time, numerous buildings have been constructed to cater to commercial purposes. Currently, there are numerous constructions such as hospitals, educational institutions, hotels, and other commercial facilities are present and even the construction of several commercial buildings is still in process. An upsurge in numerous non-residential constructions is estimated to radically increase the installation of several cooling and ventilation systems, thus the demand for HVAC relay systems is increasing at a significant ratio. Hence, this is estimated to boost market growth throughout the forecast period. For instance, in the U.S., the count of commercial buildings surged by nearly 5.6 million by 2020.
Rising Implementation of Automation - Automation refers to technological applications where the amount of human input is reduced. This encompasses home automation, industrial automation, business process automation (BPA), and more. Automation can be utilized in any sector where repetitive operations are prevalent. Currently, automation is being utilized in all most every sector. Hence, the rising utilization of automation is significantly boosting the demand for HVAC relay systems. For instance, almost 69% of organizations worldwide deploy business process automation technologies to increase end-to-end visibility across several systems.
Increasing Investments in the Residential Sector – For instance, in 2022, Germany's residential sector investment volume augmented approximately USD 12.5 billion.
Technological Innovations in HVAC Solutions – For instance, solar-powered HVAC systems are becoming increasingly popular. These HVAC systems heat and cool buildings by harnessing the sun's energy and lessening carbon footprints.
Expansion in the Internet of Things (IoT) – HVAC systems have been upgraded by the implementation of new technology. The implementation of the internet of things (IoT) is proving more helpful in real-time data monitoring and collection. In this way, they assist by collecting significant data to simplify manufacturing operations and discover flaws in production processes. Moreover, the use of IoT in HVAC equipment is highly essential for tracking vibration, airflow, temperature fluctuations, pollutants, and so on. Thus, the rising implementation of the internet of things network in HVAC systems is another major factor that is estimated to proliferate the market growth in coming years. For instance, by the end of 2021, nearly 19.8 million IoT-enabled smart thermostats had been installed in the United States.
