Hydrologic engineer with broad-based experience in ground and surface water hydrology, specializing in numerical modeling for water supply, environmental, and geotechnical applications. Tiraz has developed models at the regional, basin, and site scales, including several Superfund sites. His models have been utilized for designing optimal wellfields and dewatering systems, delineating wellhead protection areas, determination of aquifer safe-yield, minimizing environmental impacts on wetlands, predicting migration of hazardous contaminants, formulating environmentally sound and quantitatively efficient water management policies, performing remedial investigations, and developing remedial strategies. Tiraz has extensive experience in assessing the impacts of groundwater development on coastal aquifers contaminated by encroaching seawater, and has coordinated team efforts on the construction of several large-scale density-dependent solute transport models to predict the migration of seawater along the coastal regions of the United States. He is also the author of a numerical model to assess the impact of brine migration on stream-aquifers systems.
In addition to porous media, Tiraz has developed flow and contaminant transport models for fractured systems. He has also developed basin-scale coupled surface-groundwater simulator to analyze the impact of climatic, hydrologic, hydrogeologic, and anthropegenic forces on inter-connected hydrologic systems. Dr. Birdie is experienced in the analysis and optimal design of water distribution networks, and integrated groundwater-well-pump-distribution system modeling. He has developed the first integrated aquifer-well-pump-distribution system numerical model.

Richard A. Gordon, MS, PE
Ground-Coupled Heat Pump & HVAC System Design
Richard A. Gordon holds a Master’s degree in Industrial Engineering and has over 40 years of HVAC systems design and construction experience. He was one of the early embracers of the Ground-Coupled Heat Pump (GCHP) technology, which is now a key element in all comprehensive energy conservation projects analyzed and designed by him. Richard was the Engineer of Record for the design of the largest GCHP systems in the world at Fort Polk, Louisiana, in 1994, which consisted of individual ground-coupled heat pumps installed in each of the over 4000 living units at the base. This project was extensively monitored by Oak Ridge National Laboratories (with Mr. Gordon’s assistance)and formed the basis for the (Geothermal) SuperEnergy Savings Performance Contracts (Super-ESPC) program established by the U.S. Department of Energy. This project saved over 26 million kWh per year, or 33% of all electrical energy used in family housing at Fort Polk. Over the years, Richard has designed and analyzed GCHP systems at over 20,000 Department of Defense family housing units and over 250 commercial and public facilities, for a total project value of over $65 million.
Mr. Gordon has been providing consulting and design services focusing on the analytical requirements for energy conservation, renewable resources, and environmental sustainability since 1972. Richard is currently focused on HVAC design issues in extreme climates: from hot and humid to permafrost regions. This has included working with various manufacturers that are developing products and materials to significantly improve HVAC systems using sustainable sources while simultaneously minimizing energy utilization. Examples includes hybrid seawater HVAC systems, ground coupling of heat pump and modular chillers, the integration of distributed power and Combined Heat Power (CHP) systems, and development of innovative high performance/economical green house facilities.
Mr. Gordon has extensive experience in the development of procedures to perform Utility Bill Analyses (Energy Accounting) and establishment of detailed Energy Baseline which is a key component of Investment Grade Audit for Demand Side Management and Energy Performance Service Contracts. In addition, Mr. Gordon has been active in the development of data acquisition systems necessary for Measurement and Verification Programs. To date, Richard has performed comprehensive energy audits on over 1,000 commercial buildings and has extensive experience in applying instrumentation, modeling and other analytical tools to solve difficult HVAC design problems. The experience and knowledge gained from these activities provides the impetus for Richards’ current focus on the design of effective and economical GCHP systems for both retrofit and new facilities.
