David Baylon, Principal and President of Ecotope, Inc. has been in this field since 1975, and has authored or co-authored many of the key studies that have informed the Pacific
Northwest's approach to energy conservation in both the residential and commercial building sectors. Since 1987, Mr. Baylon has managed and co-authored several reviews of energy codes and standards in the Pacific Northwest. This has included reviews of residential energy codes for the Bonneville Power Administration, the Northwest Power Planning Council, the State of Oregon, and for various jurisdictions in the State of Washington. In the non-residential sector, Mr. Baylon's authored or co-authored reviews of code compliance and code enforcement in Washington and Oregon have been used to form simplified enforceable energy codes in these states. Mr. Baylon has also provided review and consultation services regarding energy efficiency in residential and commercial buildings to numerous private clients.

Over the last 21 years, Ecotope has provided some of the most significant analysis in the Pacific Northwest region, and Mr. Baylon has managed many of these projects. Mr. Baylon holds a Bachelor of Arts degree in Architecture and a Masters degree in Sociology, both from the University of Washington. Historically, his work has focused on energy-efficient engineering in buildings, and this remains his primary professional interest.


Larry Palmiter has been Senior Scientist at Ecotope for the past 20 years and is a nationally recognized expert on residential energy use. He has published more than 80 technical papers on solar energy, building use energy simulation (including primary authorship of
SUNDAY, SUNCODE, and SERI-RES, widely-used simulation tools), appliance performance, building infiltration and ventilation measurement and modeling, numerical methods, and duct system measurement and modeling. He has managed several major research projects for the Bonneville Power Administration, the Electric Power Research Institute, and other agencies and is frequently consulted by other leaders in the energy research field. Mr. Palmiter is the author of the duct efficiency testing protocols and duct simulation model used in Ecotope's duct research to date.

Shelly Borrelli began working with Ecotope in 1986. Her expertise are in database programming
and management, project-related interviewing and coordination, technical writing and editing, and project management and coordination support.

Ms. Borrelli has worked on most of the major research projects conducted by Ecotope in the past 16 years. Projects in which she played a major role include the 1996 Washington Nonresidential Code Compliance Survey (interviewing and database development and maintenance), the 1999-2000 Baseline Survey conducted for the Northwest Energy Efficiency Alliance (project coordination, database development, programming and maintenance, oversight of interviewer training and quality control), and the Resource Assessment of Energy Efficiency Measures for the Residential, Commercial and Industrial Sectors for the Energy Trust of Oregon, Inc. (project management, residential sector analysis).


Molly Curtz spends her time at Ecotope scaling off building plans, generating spreadsheets and CAD drawings, reading through codes,
running simulation software, and occasionally climbing into crawlspaces. A native of the Puget Sound area, she holds a Bachelor's of Science degree from the Evergreen State College. Molly has worked at Ecotope since 1998. Previously, she worked harvesting clams and mussels on Totten Inlet. When not at the office she enjoys commuting by bicycle, printmaking, and playing the banjo.

Bob Davis For the past twelve years, Bob Davis has conducted research on building energy usage, duct system losses, and heating/cooling system performance. He designs mechanical systems for new and retrofit applications. He often consults with builders, manufacturers, and other researchers on problem homes.

He has trained HVAC and weatherization technicians and others in the use of field testing protocols, including real-time heating system distribution system efficiency tests, specialized HVAC equipment testing protocols, and infiltration/ventilation testing. His current research projects include residential heat pumps and commercial rooftop units.

He has a low voltage certification from the state of Washington and has a Universal EPA refrigerant certification.

From 1985-1989, he worked as an energy program evaluator at the Washington State Energy Office.

He attended Deep Springs College and Stanford University before graduating in 1986 with a B. S. in Chemistry and Energy Systems from The Evergreen State College.

Paul Francisco is a research scientist at Ecotope, Inc. He has worked on energy efficiency and airflow in residential and small commercial buildings since 1993. Major recent projects have focused on thermal distribution research, including duct leakage and air handler flow measurement, measurement of duct efficiency
improvements due to retrofits,and the performance and potential for savings in rooftop package units in small commercial buildings. Paul is currently principal investigator for a project funded by the National Energy Technology Laboratory to evaluate new test methods for estimating duct leakage.

Paul is a member of ASHRAE, and has been active in the development of ASHRAE Standard 152P (Method of Test for Determining the Design and Seasonal Efficiencies of Residential Thermal Distribution Systems).

Paul received his Bachelor's degree in Mechanical Engineering from the University of Delaware and his Master's degree in Mechanical Engineering from the University of Washington.


Jonathan Heller is a licensed professional mechanical engineer in the State of Washington. He has worked for Ecotope Inc. since 1986. Mr. Heller holds Masters and Bachelors degrees
in Engineering from the University of Washington and a liberal arts degree from the Evergreen State College. He is a member of the American Society for Heating, Refrigeration, and Air-Conditioning Engineers (ASHRAE).

During his tenure at Ecotope, Mr. Heller has acted as a field auditor, researcher, project manager, data analyst, building performance modeler, consultant, and lead mechanical engineer.

During a 1-year sabbatical in the mid-1990s Mr. Heller served as technical liaison to a community development project in rural El Salvador. He provided community development consultation, organizational support and technical support in the development of an agricultural cooperative.


Erin Kruse A lifelong Michigander, Erin recently chose to trade in her snow shovel for an umbrella and join the hordes seeking
greener pastures in the Pacific Northwest. She joined the Ecotope team in April of 2002 and focuses mainly on the company's research interests. Erin earned her bachelor's degree in mechanical engineering at Michigan Technological University. Not yet ready for the real world, she then continued on in academia (and at Michigan Tech), earning an M.S.M.E. with an emphasis in nonlinear modeling and control.

Aside from "Research Scientist", Erin also considers herself an avid backpacker, gardener, stained glass artisan, and belay device.



Shawn Oram is an E.I.T registered engineer assisting in energy code submittals, mechanical systems CAD work,
building performance simulations, field auditing and research. Shawn grew up in southeast Michigan and attended Michigan State University where he received his Bachelor's of Science degree in Mechanical Engineering. Shawn has lived in Seattle since 1997 where he has held jobs in the aircraft industry and electronics manufacturing industry. He has worked at Ecotope since June 2002.

When Shawn is not at his desk crunching numbers he enjoys snowboarding, long-boarding, backpacking, organic gardening, beer making, live music collecting, bass and guitar playing and recording music.


Ellen Tepper grew up mainly in the Seattle area, besides 3 years in Israel and 1 year in Italy with her family.
In high-school, she lived in Japan for a year as an exchange student, and in college returned to Japan for another year of study. She graduated from The Evergreen State College in 1989 with a degree in Liberal Arts and Japanese Studies. Since then she has been doing administrative work. She earned her MBA at Seattle University in 2000. After graduating from Seattle University, Ellen and her husband pursued their long-time dream of travelling around the world, spending nearly 2 years travelling, and visiting 38 countries.
