Underground Energy Service Offerings
Underground Energy offers unique expertise and experience in applied hydrogeology and geothermal innovation: Underground Thermal Energy Storage. Our focus is on energy savings that can be achieved by optimizing the Earth couple when thermal energy is stored seasonally. We design and construct highly efficient geothermal eating and cooling systems for green buildings. We deliver savings in life-cycle energy costs realized by site-specific application of underground thermal energy storage technology. We can provide turnkey design and construction management services from feasibility evaluations to commissioning of building energy systems.
