Andrews Hammock & Powell

Andrews, Hammock & Powell, Inc. offers a variety of engineering and technical services to Consulting Engineers, Architects, Owners, Contractors and other Clients to help insure the long-term successful operation of Geothermal Heat Pump (GHP) Systems. Sometimes GHP systems are referred to as Ground Source Heating and Cooling (GSHC) or Geo-Exchange Systems. In the Engineering arena, we provide design services from Ground Loop Heat Exchanger (GHX)-only modeling/engineering, to the integrated design of the entire GHP/GHX system inside and outside the building. We also provide Research, Development, Engineering and Demonstration capabilities for advanced GHP system "Architectures" like Underground Seasonal Thermal Energy Storage (USTES) systems. We were recently selected by DoD to demonstrate two forms of USTES: Borehole Thermal Energy Storage (BTES) and Aquifer Thermal Energy Storage (ATES). On the Technical Services side, we perform in-situ Thermal Conductivity Testing (TCT) of the underground formation for conventional GHP systems and BTES systems, Technical Services for ATES and Open Loop systems as well as other related services. We are also a National Environmental Balancing Bureau (NEBB) certified firm in both Testing/Adjusting/Balancing (TAB) and Commissioning (CxA). In the CxA arena we provide LEED-compliant Basic and Enhanced CxA, ASTM-compliant GHX Pressure testing, GHX purging/ flushing Monitoring and more. Beyond having Professional Engineers (PE) on staff registered in multiple states, and the capability of obtaining PE registration in any state, we also have a PE on staff that holds the International Ground Source Heat Pump Association's (IGSHPA) Certified Geothermal Designer (CGD) credential.
