HVAC industry has experienced rapid changes over the past year that have pushed professionals and manufacturers to rethink how they approach sustainability, building health and workforce development. The pandemic magnified the importance of Indoor Air Quality (IAQ) both at home and within commercial buildings. The effects of climate change backed by governmental policy have accelerated the need for energy-efficient systems that can help to support aggressive sustainability goals and reduce energy costs. A waning workforce and continual supply chain disruptions are sources of ongoing pressure within the industry as product demands grow. And yet, as both market conditions and the industry itself evolves, the future of HVAC remains positive with innovation and strategic planning guiding the way.

So, what are the issues shaping the HVAC industry? And what best practices contractors and building managers ought to adopt to meet evolving industry standards?

REGULATIONS AND ENERGY EFFICIENCY 

After years of preparation, 2023 marks the launch of increased US Department of Energy (DOE) standards for residential as well as light-commercial applications. It’s critical that contractors understand which region they’re located in – as specified by the DOE – and the types of products HVAC industry has experienced rapid changes over the past year that have pushed professionals and manufacturers to rethink how they approach sustainability, building health and workforce development.

ACCELERATED SUSTAINABILITY GOALS

With the United States rejoining the Paris Agreement and strengthening 2030 greenhouse gas emission targets, decarbonisation, electrification and low-Global Warming Potential (GWP) refrigerant transitions are at the centre of the accelerated sustainability goals of the United States.

Homeowners and commercial building managers can both benefit from electric-based heating and cooling systems and advanced controls that enhance performance and efficiency.

The Energy Efficiency Indicator Survey revealed that 62% of commercial organisations surveyed expect to increase investments in energy efficiency, renewable energy or smart building technology in 2023. In parallel, the American Home Comfort Study indicated that 60% of homeowners were willing to invest in high-efficiency systems this year if they could lower their energy consumption and the associated costs.In both markets, advanced controls play a critical role in supporting HVAC system efficiency.

For homeowners, communicating zoning systems combine the benefits of smart home technology with energy-efficient zoning. And zones established throughout the home allow homeowners to reduce heating and cooling in unused rooms or make adjustments based on ambient conditions. Additionally, automated settings can be used to create preferences while away,

providing superior control over the home comfort system and its energy use. Advanced commercial building management systems that incorporate artificial intelligence (AI) provide operators with a comprehensive suite of apps to monitor and improve energy efficiency, asset performance, maintenance operations, and occupant satisfaction and wellbeing. These systems take smart building controls a step farther with real[1]time tracking and automatic data analytics to provide a roadmap of sustainability opportunities and metrics that help facility managers understand and communicate the impact these efforts have on building performance.

 WELLNESS AND IAQ  

In both residential and commercial markets, the necessity for healthy IAQ is paramount, as IAQ shifts from a pandemic precaution to a method of enhancing overall wellbeing.The 2022 American Home Comfort Study revealed homeowners were willing to spend 65% more on IAQ now than they were just a few years ago. Wellness, ventilation, IAQ, thermal health and humidity make up half of the nine key pillars of healthy commercial buildings identified by the Harvard School of Public Health. [ii] These findings, coupled with the launch of the US Environmental Protection Agency’s (EPA) Clean Air in Buildings Challenge, make HVAC performance and healthy indoor environments more important than ever before.

Maintaining optimal space temperature and humidity levels not only provides a more comfortable indoor environment, but they also help destabilise pathogen transmission and prevent mould and mildew growth within the system and minimise its potential to spread throughout the building. Increased ventilation, advanced MERV filters, humidifiers/ dehumidifiers and ultraviolet-C systems work together as a complete system that can be applied to residential as well as commercial applications. System controls further enhance performance by providing insights into IAQ performance. In commercial buildings, this can be advanced through smartphone apps that make building data transparently available to all occupants.

Apps also allow occupants to communicate directly with facility personnel about building and room conditions like temperature, lighting and occupancy to provide superior control over personal wellbeing. WORKFORCE DEVELOPMENT Efforts to recruit and train the next generation of HVACR professionals continue, but there is more work required to strengthen the future of the industry.

On-the-job training opportunities can help attract new contractors and develop the skills necessary for continued professional advancement. The Manufacturing Institute estimates that over two million manufacturing jobs will be unfilled by 2028 largely due to the current skills gap. HVAC manufacturers have an opportunity to play an important role in this development by investing in and providing hands-on and virtual training resources. On-site classrooms and laboratory-style training environments that include access to real HVAC systems and emulate real-world settings and environmental conditions, provide a valuable knowledge base.

But additionally, virtual reality can be used to further expand expertise by simulating scenarii that are common within the field, such as servicing or installing equipment. Combining virtual reality with remote learning opportunities can help to make training and career possibilities more accessible to a wider range of potential HVAC professionals.
