Buffet Breakfast: 7:30 ~ Program: 8:00 - 9:00 AM
Join us on Tuesday, March 30, 2010 from 7:30 - 9:00 AM at the Eastland Park Hotel, 157 High Street, Portland, ME as our panelists present an overview of the application of geothermal heating and cooling on real estate development projects in New England.
Ground source geothermal energy enables us to tap into the earth’s stored renewable energy for heating and cooling facilities. Proper application of ground-source geothermal technology can have a dramatic impact on the efficiency and financial performance of building energy use (~30 %). At the same time, using this alternative energy resource can provide significant value in meeting carbon and nitrogen oxide reduction goals. Geothermal applications also offer the possibility of aesthetic and noise abatement benefits (eliminating cooling towers and dry coolers in sensitive locations or on historic structures) and, when combined with “green” or lower cost, on-site electrical power, the benefits are many.
Our presenters will discuss the basics of geothermal energy - how it works and the types of systems used widely in New England. Mr. Kastrinos will describe some fundamentals of well hydraulics and aqueous geochemistry, which are key parameters affecting the cost-effectiveness and technical feasibility of geothermal systems. Mr. Ormond will describe a two-phase approach to assessing the feasibility of geothermal at a commercial scale. This approach comprises an initial phase of data gathering, including assessing state and local permitting requirements, followed by Phase 2, which includes installing a full-scale test well, ultimately suitable for use as a production well, for thermal response testing. This two-phase program provides the critical data needed to accurately determine the number and depth of the production wells and layout of the well field. This information enables a refined decision-making process yielding superior financial and engineering performance. In addition, these data allow the geothermal engineering professional and the building mechanical engineer to properly size and integrate the well system, heat exchangers and ground source heat pump equipment into a fully functioning, seamless HVAC system.
Meet our Panelists:
Paul F. Ormond, P.E. is Senior Engineer at Haley & Aldrich and has 13 years of experience as an engineer on a wide variety of geothermal, geotechnical, and environmental development projects. Paul is a leader in geothermal engineering and has developed many innovations in this practice area, including new methods of pilot testing, design, and analysis. A keen interest of Paul’s is developing more robust geothermal and conventional system integration approaches, with an eye for optimizing financial performance, efficiency gains per dollar invested, and reliability. Paul’s geothermal project experience ranges from single family home projects to campus-wide district networks having integrated geothermal and central plant systems. He is also an active participant in creating new regulatory standards for geothermal development in several states. Paul received his Bachelor’s degree in Civil Engineering from Worcester Polytechnic Institute and his Master’s degree in Civil Engineering from University of Massachusetts. He is a registered professional engineer in Massachusetts.
John R. Kastrinos, P.G. is Vice President of Haley & Aldrich and has over 25 years of experience in hydrogeology applied to a broad range of projects involving contaminant transport, groundwater supply wells, groundwater remediation, construction dewatering, and ground-source heat pump (geothermal) energy systems. Mr. Kastrinos has applied his background in hydrogeology to helping clients assess the feasibility of geothermal systems for both new development projects and retro-fits. He is also experienced with diagnosing operation and maintenance (O&M) problems associated with open geothermal systems (i.e., those systems that circulate groundwater) and prescribing solutions that reduce O&M labor and costs. Mr. Kastrinos is a registered Professional Geologist in the State of Pennsylvania and an American Institute of Hydrology (AIH) certified Professional Hydrogeologist (P.HG.).
