Case Summary:     

When it comes to solving the urgent challenges of decarbonization and energy conservation, some researchers focus on the future. Others, like this research engineer from China, built it. With the approval of his EB-2 NIW (National Interest Waiver) petition, his groundbreaking work in energy-efficiency technologies has now been formally recognized as being of exceptional value to the United States.

Working at the cutting edge of sustainable engineering, this researcher has developed novel heat pump technologies that enhance heating and cooling efficiency. This area accounts for nearly half of U.S. household energy consumption and contributes significantly to national carbon emissions. His research aims not only to reduce environmental impact but also to transform building systems by integrating human behavioral data with mechanical innovation.

His academic output includes a first-authored peer-reviewed journal article, five first-authored peer-reviewed conference papers, a preprint, and a book chapter. His work has already been cited at least 16 times. His paper in Energy and Buildings—a journal with an impact factor of 6.6—has garnered particular attention for introducing the wall-embedded micro heat pump (WEMHP), a compact and scalable system that demonstrated up to 23% energy savings.

In addition to his publications, he has contributed at least 17 peer reviews for reputable journals and conferences, including ASHRAE and Science and Technology for the Built Environment, confirming his respected status among experts in the field.

His work has also earned competitive support from organizations like the National Science Foundation and ASHRAE, whose mission includes promoting energy-efficient building technologies to benefit public welfare and economic development.

A senior professor summarized his broader impact:

“[Client’s] research reduces energy costs for homeowners and provides insights that drive economic growth by creating new avenues in the energy-efficient technology sector… He stands as a critical figure in energy-efficiency technologies, advancing both scientific understanding and practical solutions to pressing challenges across the US.”

His EB-2 NIW petition emphasized the originality of his research, such as conducting one of the first real-world field and lab studies on thermostat-adjustment behavior in different heat pump operation modes. By marrying experimental and behavioral data, he produced actionable insights into improving thermal comfort while lowering energy use—tools that engineers, policymakers, and homebuilders can apply today.

We demonstrated that his track record, peer recognition, and nationally funded projects place him among the top minds in his field. With a clear trajectory of continued innovation, he is uniquely equipped to lead the U.S. toward its energy efficiency and sustainability goals.

At NAILG, we are proud to have helped secure this EB-2 NIW approval and support the work of a researcher whose vision for energy systems doesn’t just imagine a better future—it builds it.
