Amazon is increasing the use of rooftop cooling technology developed by Transaera after a successful trial showed it significantly cuts energy use at one of the company’s logistics sites. This step marks a wider rollout of a heat pump-based HVAC system aimed at improving cooling efficiency and lowering emissions across Amazon’s operations.

The partnership reflects the growing focus on HVAC efficiency, heat pump technology, and energy savings, as businesses look for practical ways to lower their emissions while addressing the rising electricity demand from cooling systems.

Amazon Moves Pilot Project Into Commercial Deployment

Amazon and Boston-based Transaera announced a multi-year commercial agreement after a six-month field trial at an Amazon logistics facility in hot and humid conditions. The companies stated that the rooftop HVAC system consistently used less energy than traditional cooling systems while maintaining indoor performance.

An independent third-party analysis confirmed the energy efficiency improvements during the trial. After reviewing the results, Amazon decided to include this technology in its overall heating, ventilation, and air conditioning strategy across warehouses and operational sites.

Amazon stated that this partnership supports its Climate Pledge goal of achieving net zero carbon emissions by 2040. The company has been investing in lower-emission technologies across transportation, buildings, renewable energy, and supply chains as part of its broader effort to reduce carbon emissions.

Asad Jafry, Director of Global Energy, Sustainability, and AGV at Amazon, mentioned that the partnership has progressed from testing to readiness for commercial use, allowing the company to expand the technology’s deployment across its global building network.

Cooling Demand Drives New Efficiency Solutions

The commercial building sector is under growing pressure to reduce electricity use as cooling demand rises worldwide. Higher temperatures and humidity have led to increased reliance on air conditioning, especially in large industrial and logistics facilities where climate control is vital for operations and employee comfort.

Typical rooftop cooling systems eliminate humidity by overcooling air and reheating it to maintain indoor temperatures. This process requires more electricity and raises operating costs.

Transaera’s system takes a different approach by separating humidity removal from cooling. The technology uses advanced solid desiccant materials known as Metal Organic Frameworks, or MOFs, to absorb moisture before the air is cooled. By reducing the energy needed for dehumidification, the system lowers the overall demand on cooling equipment.

The company estimates that the technology can lower energy use by about 40% compared to conventional packaged direct expansion systems commonly found in commercial buildings.

Focus on Electrification and Indoor Air Quality

Transaera’s first commercial product is a Dedicated Outdoor Air System, or DOAS, which the company claims exceeds the current federal minimum efficiency standard for moisture removal by more than double.

This system also acts as a heat pump, providing cooling, heating, and dehumidifying capabilities without needing natural gas reheat systems. This feature aligns with trends toward building electrification as companies aim to cut fossil fuel use in real estate operations.

Industry analysts increasingly consider building emissions as a key area for corporate climate strategies. Commercial real estate contributes a large share of global energy-related emissions, with HVAC systems consuming a significant amount of electricity in office buildings, warehouses, and industrial facilities.

Improved humidity management not only reduces electricity demand but also enhances indoor air quality and occupant comfort. These factors are becoming more important for employers and logistics operators managing large indoor spaces.

Sorin Grama, CEO and Co-founder of Transaera, stated that HVAC systems account for over a third of energy use in commercial buildings, describing the technology as a way to lower operating costs while enhancing indoor conditions.

Manufacturing and Supply Chain Expansion

The agreement also includes manufacturing commitments to meet Amazon’s future HVAC needs. Transaera plans to allocate part of its U.S.-based manufacturing capacity to supply systems for Amazon facilities.

This expansion comes as governments and companies emphasize domestic manufacturing, supply chain resilience, and energy infrastructure investment. Advanced HVAC technologies are increasingly seen not just as climate solutions but also as essential parts of industrial and energy security strategies.

For Amazon, this deployment offers another way to cut emissions beyond renewable electricity and carbon offset programs. Boosting efficiency in buildings can directly reduce electricity demand and support long-term cost management.

The partnership reflects broader changes in the cooling market as companies look for systems that can handle higher temperatures and humidity while meeting energy performance standards.

Grama stated that the agreement shows high-efficiency HVAC systems are moving into mainstream use rather than staying niche technologies. He added that the collaboration aims to demonstrate how energy-efficient systems can provide long-term economic and operational benefits for large facilities.

As cooling demand rises in major markets, companies are increasingly expected to adopt technologies that lower energy use, support electrification goals, and improve building resilience. Amazon’s expanded collaboration with Transaera highlights the growing interest in next-generation HVAC systems as part of broader efforts to reduce carbon emissions.
