At The GreyEdge Group (TGEG), we challenge the standards for energy efficiency, effective decarbonization, and thermal comfort at scale. We are leading the heating and cooling transformation towards a more sustainable, reliable, and resilient future.
Learn MoreThe GreyEdge Group specializes in the engineering, and design of complex thermal energy network systems using the Thermal Highway©. These are also known as an Ambient Temperature Loop (ATL) or Thermal Energy Network (TEN). Successful systems are operating around the world delivering clean and comfortable heating and cooling on projects ranging from single-family homes to large district geothermal systems including university campuses and a 123-story skyscraper.
Our team continues to evolve the breadth and scale of its services in innovative ways. Using the unique Thermal Highway© concept, we offer access to additional thermal energy sources including solar thermal heat, wastewater heat, industrial waste heat, thermal heat storage, and large-scale recycling of thermal energy. Our solutions can scale up to large geographic areas by connecting integrated multi-sources into thermal energy districts. This powerful combination delivers system performance at much higher efficiency, with lower project cost, and lower operating cost than traditional unintegrated geothermal systems.
The members of the GreyEdge Group team have been committed to the ground source heat pump industry for many years. A combined total of over 250 years of experience in almost all facets of the industry around the world from projects ranging from single family homes to large district geothermal systems, give us unparalleled expertise in one of the most energy efficient heating and cooling technologies available.
The GreyEdge Group partners have worked on hundreds of geothermal projects, including 12 ambient temperature loop projects going back as far as 2002. We have experience with various building types, including university campuses, healthcare facilities, skyscrapers, towns, and more. Feel free to reach out to us and learn about other projects we have worked on.
