Another emerging trend that is anticipated to have a favourable impact on the construction sector is the rise in the number of net-zero buildings. These structures are designed to use less energy. In particular, it is anticipated that this increase in net zero-building popularity would accelerate the growth of the non-residential sector in the years to come, supporting the expansion of the HVAC market.

Additional anticipated drivers for the HVAC industry include population growth, rapid urbanisation, and increased disposable incomes. One major trend that is anticipated to have an impact on the market over the forecast period is the necessity to maintain an ambient climate in a building due to changing climatic conditions. Most end-users have recently prioritised the availability of smart features and energy efficiency when making purchases, and this trend is anticipated to continue over the coming few years.

The ongoing transition to low-GWP refrigerants such as R-32 and R-454B, the rapid adoption of all-climate heat pumps, and the increasing integration of AI-driven building analytics and IoT-enabled predictive maintenance platforms are redefining the competitive landscape. Surging demand for HVAC systems in data centers, hospitals, and hyperscale commercial facilities is also creating new high-growth segments for leading manufacturers worldwide.
