HVAC Decarbonization: 6 Key Strategies Toward a Net-Zero Future

With buildings contributing nearly 40% of global energy consumption and greenhouse gas emissions, decarbonizing and electrifying HVAC systems is a vital to a cleaner, more sustainable environmental future. 

New Jersey has set ambitious goals for eliminating greenhouse gas emissions. The state’s Energy Master Plan aims to source 50% of its electricity from renewable sources like solar, wind, and nuclear by 2030, phase out fossil-fuel based electricity generation by 2035, and reach 100% clean energy across all sectors by 2050. Here are six key steps you can take toward achieving your facility’s decarbonization goals: 

Conduct Comprehensive Energy Audits

This first important step identifies inefficiencies, assesses equipment performance, and establishes baseline energy consumption levels. Energy audits provide valuable insights into areas that need improvement and help prioritize upgrade decisions.

Implement Energy Efficiency Measures

These may include upgrading to high-efficiency HVAC equipment, optimizing system controls, addressing duct leaks, improving insulation and air sealing, and incorporating energy recovery technologies. 

Electrify HVAC Systems

Transitioning to electrified systems, such as air-source heat pumps, ground-source heat pumps, and VRF systems, is a key decarbonization strategy. These systems are more energy-efficient and can be powered by renewable energy, further reducing emissions. 

Integrate Renewable Energy

To achieve true decarbonization, integrate renewable energy sources like solar photovoltaic (PV) systems or wind turbines. On-site renewable energy generation can power HVAC systems, significantly reducing or eliminating their carbon footprint.

Explore Thermal Energy Storage

Technologies like ice storage or phase change materials, in which stored thermal energy is utilized on-site during peak demand, can help balance the intermittent nature of renewable energy and can enhance HVAC efficiency and reliability. 

Engage Stakeholders and Provide Training

Successful decarbonization requires collaboration among building owners, facility managers, contractors, and occupants. Knowing the benefits of low-carbon HVAC systems and how they operate is crucial for widespread adoption and proper maintenance.
