Roger Hedrick TITLE Principal Engineer PRINCIPLE DUTIES AND RESPONSIBILITIES Residential System Testing, Energy System Analysis, EDUCATION B.S. Mechanical Engineering,
University of Illinois,1978 EXPERIENCE Mr. Hedrick has extensive experience in development of PC-based energy analysis, economic analysis and cost estimating programs, the design of HVAC systems, energy audits of buildings, and the design and installation of computer-based data acquisition systems for characterizing the performance of advanced HVAC systems. He is the program manager for the Gas Research Institute’s Conventional Research House, where he has tested a number of advanced heating and cooling systems and studied the impact of the thermal distribution system on equipment performance. Mr. Hedrick is currently involved in a project to evaluate the potential energy savings of changes to the California state energy code to address duct leakage in commercial buildings. He is using manual calculations using ASHRAE Standard 152P procedures and DOE-2 modeling to investigate the possible energy savings. He will establish energy savings factors which can then be applied to a database of buildings representing all new commercial construction in California. Mr. Hedrick has recently completed an evaluation of home energy rating systems (HERS) for the Gas Research Institute. Mr. Hedrick studied a number of widely used HERS, evaluating the rating method and sensitivity of the simulation program used as the rating tool, particularly in terms of comparisons between gas and electric heating systems. During this project, a number of white papers were prepared to assist GRI staff on a variety of HERS related topics. Other experience at GARD includes several energy conservation projects, including a feasibility study of a cogeneration system for the U. S. Army Detroit Arsenal, feasibility and life cycle cost analyses of Energy Management Systems at several installations, and performing an electrical submetering study at the Detroit Tank Plant. Mr. Hedrick has a strong background in system analysis. He has conducted several analyses for the U. S. Postal Service of vehicle operating costs in the rural mail delivery environment and in city mail delivery operations. He has also developed detailed simulation models of maritime cargo container terminal operations for the Cargo Handling Cooperative Program, and of industrial applications for GARD-developed material handling and sorting systems. Mr. Hedrick is currently a member of three ASHRAE Standards Project Committees: · Standard Project Committee 62.2P, “Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings,” Voting Member · Standing Standards Project Committee 62.1, “Ventilation for Acceptable Indoor Air Quality,” Subcommittee Voting Member · Standard Project Committee 152P, “Method of Test for Determining the Steady-State and Seasonal Efficiency of Residential Thermal Distribution Systems,” Subcommittee Voting Member Prior to joining GARD, Mr. Hedrick worked for Enercon, Ltd., and Perkins and Will, successively. These two positions involved Mr. Hedrick in a wide variety of computer-based analysis and energy conservation and design projects. He has used computer simulation programs extensively, including DOE-2, BLAST and Meriwether Energy Programs. AFFILIATIONS American Society of Heating,
