Amazon has signed commercial agreements with two energy technology firms to deploy advanced HVAC systems across its global building portfolio, accelerating a multi-track decarbonization strategy spanning AI-driven controls and next-generation dehumidification. The moves, disclosed in May 2026, signal a shift from isolated pilots to portfolio-wide design standards and carry significant implications for commercial HVAC procurement and the broader building decarbonization market.
Background
Amazon has pledged to reach net-zero carbon emissions by 2040 under The Climate Pledge. Buildings represent a critical component of that commitment: the company operates a vast portfolio including fulfillment and logistics facilities, grocery stores, corporate offices, and data centers across multiple continents. According to Amazon's sustainability disclosures, its strategy targets both decarbonizing existing buildings through smart technology and reducing embodied carbon in new construction.
HVAC systems account for over one-third of energy use in commercial buildings, according to Transaera CEO Sorin Grama, making them the primary lever in any large-scale building decarbonization program. The building sector as a whole accounts for roughly one-third of global energy consumption and a comparable share of energy-related carbon dioxide emissions, according to a 2025 review published in Applied Sciences.
Details
The first partnership involves Trane Technologies and its subsidiary BrainBox AI, which deploys autonomous AI to optimize HVAC controls without hardware replacement. An initial deployment at three pilot Amazon Grocery fulfillment facilities in North America achieved energy-use reductions of nearly 15% - more than double the original project targets, according to a joint announcement from the companies. Trane Technologies acquired BrainBox AI in January 2025 after more than two years of joint development. The BrainBox AI platform connects to existing building management systems via cloud infrastructure and autonomously issues real-time control commands to minimize energy consumption and emissions.
"At Amazon, we're continually looking for data-driven, scalable solutions to reduce our carbon footprint while maintaining operational excellence," said Christina Minardi, Vice President of Worldwide Grocery Stores Real Estate and Store Development at Amazon.
The second agreement involves Boston-based startup Transaera, which has developed a Dedicated Outdoor Air System (DOAS) that uses solid desiccant materials - specifically Metal Organic Frameworks (MOFs) - to strip humidity from incoming air before cooling occurs. The system is designed to reduce energy consumption by approximately 40% compared to conventional packaged direct-expansion (DX)-only systems, while maintaining compatibility with existing rooftop HVAC footprints, according to ESG Today. Amazon tested the unit at a Houston facility for six months before signing a commercial agreement that reserves manufacturing capacity over the next three years.
Transaera's DOAS is designed to remove approximately 100 pounds of water from the air per hour and demonstrated more than double the current federal minimum efficiency standard, according to the company. The proprietary desiccant belongs to a class of materials whose discoverers received the 2025 Nobel Prize, though the specific compound has not been disclosed. Transaera says total customer purchase targets from all buyers have reached nine-figure levels, with Amazon as the anchor customer.
"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.
A key commercial detail is the integration model: Transaera's desiccant system is designed as a like-for-like replacement of legacy rooftop units, fitting within standard commercial HVAC enclosures without requiring redesign of surrounding infrastructure. The company is building a U.S.-based supply chain in partnership with existing domestic HVAC manufacturers.
Outlook
Amazon's approach - standardizing proven solutions into its design template and replicating them across its building stock - sets a benchmark that mid-market commercial real estate operators will likely face pressure to match, particularly as building performance regulations tighten across North America and Europe. For HVAC manufacturers and service contractors, both deals underscore growing demand for interoperable, drop-in solutions that deliver verified performance data rather than projected savings. As AI-optimized controls and advanced dehumidification technology move from pilot to design standard, procurement managers and system designers in the commercial sector will need to evaluate both the technical compatibility and supply-chain readiness of analogous systems for their own portfolios.
