Transaera, a MIT spinoff, manufactures energy efficient rooftop air conditioning systems using MOF technology to remove moisture separately from cooling, resulting in 40% less energy usage compared to traditional systems. The systems cost 20% more but pay for themselves in energy savings within two years, with a useful life of 15 years. Metal-organic frameworks, a new class of materials, contribute to the energy efficiency gains by extracting moisture from the air. The company has partnered with manufacturers to install their systems in buildings, including a multi-year deal with Amazon to help achieve net-zero emissions by 2040. As more people and companies understand the benefits of MOF technology, the technology is expected to scale quickly, with Transaera systems offering rapid recapture of the extra cost and designed to fit seamlessly into existing infrastructure.
