• Amazon will expand use of Transaera’s rooftop HVAC technology after a six-month field trial at one of its logistics facilities showed consistent energy savings.
• Transaera’s system is expected to cut energy use by 40% compared with conventional packaged direct expansion systems.
• The collaboration supports Amazon’s Climate Pledge target to reach net zero carbon emissions by 2040, while strengthening U.S.-based advanced HVAC manufacturing.

Amazon Moves Heat Pump Trial Into Commercial Deployment

Amazon is moving a high-efficiency rooftop cooling system from trial to commercial use, adding another layer to its decarbonization strategy across a global building network that includes logistics sites, warehouses, and operational facilities.

The company and Transaera, a Boston-based cooling and dehumidification technology developer, announced a new collaboration after a successful six-month field trial at an Amazon logistics facility. The trial tested Transaera’s rooftop-based cooling system under hot and humid conditions, where traditional commercial air conditioning systems often consume more energy to manage moisture.

According to the companies, the extended trial delivered consistent energy savings compared with conventional systems, while maintaining performance in demanding conditions. Independent third-party analysis validated the efficiency benefits.

The results have now led to a broader multi-year commercial agreement. Under the deal, Transaera will integrate its system into Amazon’s heating, ventilation, and air conditioning design solutions. The company will also dedicate part of its U.S.-based manufacturing output to support Amazon’s HVAC deployment needs.

“At Amazon, we seek technologies that support our Climate Pledge goal to reach net zero carbon emissions by 2040. Our work with Transaera has moved from field trial to readiness for first commercial use, and this new collaboration supports expanding use of this technology within our global network of buildings,” said Asad Jafry, Director of Global Energy, Sustainability and AGV at Amazon.

Rethinking How Buildings Manage Humidity

The commercial building sector faces a growing energy challenge as cooling demand rises, especially in regions exposed to higher temperatures and humidity. Conventional rooftop systems often remove humidity by overcooling air, then reheating it to maintain comfort. That process adds cost and increases energy demand.

Transaera’s technology takes a different approach. It uses a new class of solid desiccant materials, known as Metal Organic Frameworks, or MOFs, to remove moisture before cooling. By separating dehumidification from cooling, the system can reduce the energy load that traditional packaged direct expansion systems carry.

The company expects energy savings of 40% compared with conventional packaged direct expansion only systems. Importantly for commercial deployment, the technology fits within rooftop designs that building operators already use.

“HVAC use accounts for over one-third of energy use in commercial buildings,” said Sorin Grama, CEO and Co-founder of Transaera. “This technology has the potential to reduce operational cost while enhancing indoor air quality and occupant comfort across commercial and industrial facilities.”

For building owners and operators, that combination matters. Lower energy demand can reduce operating costs. Better humidity control can also improve indoor air quality and comfort, which are increasingly relevant for employers, logistics operators, and facility managers.

HVAC Efficiency Becomes A Boardroom Issue

Transaera’s first product is a Dedicated Outdoor Air System, known as DOAS. The system has demonstrated more than double the current federal minimum efficiency standard for moisture removal.

It is also designed as a heat pump that can cool, heat, and dehumidify without relying on natural gas reheat. That places the technology within a wider shift toward building electrification, a key priority for companies looking to reduce direct emissions from real estate and operations.

For Amazon, the collaboration adds a practical emissions lever across its facilities. For investors and executives, the development shows how operational technology can support climate targets without depending only on renewable power procurement or offsets.

The deal also carries industrial policy relevance. Transaera is building a U.S.-based supply chain for advanced HVAC systems, supporting domestic manufacturing and skilled jobs. As companies rethink energy efficiency, supply security, and climate risk together, HVAC is becoming part of a larger infrastructure conversation.

“This announcement signals that high-performance HVAC is no longer a niche innovation—it’s becoming the new standard,” Grama added. “We’re proud to work with Amazon to demonstrate a more energy efficient technology that can deliver lasting economic returns.”

The wider significance is clear. Cooling demand will rise as heat and humidity intensify across major markets. Commercial buildings will need systems that cut energy use, protect comfort, and align with electrification goals. Amazon’s expanded work with Transaera points to a market where HVAC efficiency becomes both a climate tool and a financial discipline.
