Owing to the huge amount of energy, HVAC systems use sensors to improve equipment efficiency, which results in significant reductions in building operating costs.

  • For instance, HVAC monitoring systems include IoT sensors for monitoring temperature, occupancy, fresh air intake, and other indoor climate conditions. Controllers and actuators turn the data collected from these sensors into action. Some actions are immediate and preprogrammed into the system. Smart building management platforms with machine learning capabilities that provide in-depth insights and continuously refine adjustments carry out more complex analyses.

  • Furthermore, energy standards and building codes have also significantly driven the design of energy efficient buildings over the past decade. For instance, the US Green Building Council’s (USGBC) leadership in the Energy and Environmental Design (LEED) Green Building Rating System has raised awareness of the need for building designs that use energy efficiently. As such, several states in the country have mandated the use of the LEED rating system for government buildings.

  • Such initiatives indicate the importance of energy conservation in buildings. Hence, HVAC sensors are being commonly used because the need to reduce energy consumption is increasing, enhancing energy efficiency. As a result, the government and regulatory organizations are primarily focusing on how HVAC controls can reduce energy consumption in buildings.

  • The pandemic significantly influenced the HVAC industry, as demand for the sensors observed a significant drop during the initial months, owing to lockdown restrictions and businesses refraining from investing in new equipment. Due to the pandemic, many construction projects were halted across the world. The reduction in construction activities across the commercial, residential, and industrial sectors temporarily dampened the demand for HVAC sensors, including those for air handling units.

  • Moreover, due to the production shutdown in countries such as China, multiple industries observed a shortage of supply of various products during February and March 2020. Due to supply chain disruption, the price of raw materials increased, impacting the overall pricing of the sensors.

HVAC Sensor Market Trends

Increased Construction and Retrofit Activity to Aid the Market’s Growth

  • According to JRAIA, the global demand for room air conditioners has increased to 95.16 million in recent years. Furthermore, according to the United Nations, the world’s population was projected to reach 8 billion on November 15, 2022. The latest projections by the organization suggested that the global population could reach around 8.5 billion in 2030, 9.7 billion in 2050, and 10.4 billion in 2100. Declining levels of mortality partly influence population growth.

  • Furthermore, in emerging markets like the Asia Pacific region, especially China and India, many people have been migrating from rural areas to cities, raising government and private spending on housing, commercial construction, and infrastructure. New building construction is creating significant demand for new equipment installations for heating, ventilation, and air conditioning systems. Hence, the growing construction industry would likely drive the studied market.

  • For instance, in November 2021, the Indian government approved the construction of 3.61 lakh houses under the Pradhan Mantri Awas Yojana (Urban). The approval of the new housing units takes the total number of sanctioned houses under the scheme to 1.14 crore. Such trends positively contribute to the demand for HVAC sensors, in newly installed HVAC systems.

  • Moreover, increasing building renovation projects by the government to make them more energy-efficient are significantly increasing the global HVAC sensor market. This is because energy-efficient buildings can help reduce greenhouse gas emissions, lower energy bills for homeowners and businesses, and improve indoor air quality, thus making them suitable for public health.

  • Moreover, a country like Europe has presented the European Green Deal, an ambitious package of policy measures to make Europe the first climate-neutral continent by 2050. The European Green Deal aims to double or even triple building renovation rates and speed up building digitization to ensure the EU’s building stock is on track to decarbonize by 2050.

  • Therefore, with the growing construction and retrofit activities, there will be a significant rise in the demand for energy-efficient HVAC sensors for maintaining comfortable indoor temperatures and good air quality in buildings, owing to the need to reduce energy consumed, increasing and leading to the enhancement of energy and its efficiency.

Asia-Pacific Expected to Register Fastest Growth

  • The Asia-Pacific HVAC sensor market is predicted to rise steadily due to commercial and residential construction activity in India and China and rising consumer expenditure on luxury products. Low ownership rates and increased disposable income in Asia will likely boost the market’s growth. Due to rising demand from India and China, the residential sector accounted for a significant portion of the Asia-Pacific HVAC sensor market.

  • According to the China Construction Industry Association, in 2021, residential structures accounted for the largest share of finished construction in China. Buildings intended for housing accounted for over 67 percent of the completed floor space. As the country’s economy grows, people migrate from rural areas to major cities, increasing demand for residential accommodation in these locations. Furthermore, apartments utilized as investment properties drive up demand. Such huge residential construction is expected to drive the studied market.
