Thermal Energy and District Heating/Cooling - Various Locations


Studies or design documents have been completed for several solar/geothermal projects. We are a national leader in district heating and cooling systems having been determined to be in the Top 100 MEP Firms by Consulting-Specifying Engineer magazine.


Project Examples Follow:


Solar Water Heating System Study

A feasibility study was completed for a large-scale roof mounted solar water heating system for the Hampden-Sydney College Leggett Pool. The study included the thermal/solar evaluation, preliminary installation design (roof structural, piping, etc.) and the economic evaluation of both a flat-plate and evacuated tube collector - pumped systems. This is a non-zero carbon design, using grid power for pump/control operation.



Geothermal Heating System Study
An Energy Master Plan was completed including a feasibility study for a geothermal heating system at a major university. The study reviewed the use of the geothermal resource for either building heat and/or heating boiler feedwater for the campus central plant.



Geothermal Building Heating/Cooling System

A geothermal building heating/cooling system was designed for the facilities at the City of Roanoke, VA - Crystal Spring Water Treatment Plant. The system design uses pre-treatment spring water to transfer heat to and from water-cooled heat pumps. The system has realized high energy efficiency ratios and a low HVAC operating cost.



District Heating/Cooling Systems
Designs were completed for steam and chilled water distribution projects for university campuses, industrial facilities and large federal/state installations. Recent examples are:
  • East Carolina University – Health Services Steam Line Replacement; included over 1400 feet of steam/condensate line replacement, new manholes, condensate meters and bypass piping using “Green Principle” recycled materials where possible.
  • City of Harrisonburg (VA) - RRF 1500 Ton Chiller; included the multi-discipline engineering to replace a 370 ton chiller with a 1500 ton chiller/controls inside an existing waste-to-energy facility to service the district cooling system at an adjacent university.
  • JMU District Heating Project – included the design to connect the City of Harrisonburg RRF to the JMU district heating system, requiring 3800 LF of high pressure steam, condensate and chilled water piping in a new utilities tunnel.
