During his undergraduate studies at Cornell, Alec was a team leader of a group of students that designed, built, and raced hybrid electric vehicles long before the advent of the Toyota Prius. After graduation, he moved to Michigan to work at one of the big three, where he gained his first experience in industrial energy conservation as a process engineer on the factory floor. After deciding that Michigan was too far from the ocean and the mountains, he moved to Boston to work for an electric vehicle R&D company. In 1999, he determined that his career interests lay in the energy consulting field, and landed a job at DMI. He took over the roles of president and owner in January 2005. As the primary reviewer of DMI's work, he is involved in each project that DMI works on. Outside of DMI, Alec enjoys spending time with his family hiking, canoeing, and fishing. He also enjoys working on his old house, and has dreams of adding a garage to shelter some interesting old piece of Detroit iron.

Key Projects
Analyzed the cost effectiveness of retrofitting variable speed drives on chiller compressors and cooling tower fans for a 1,500-ton chilled water plant. Made extensive use of historical interval demand data to develop accurate load profiles, including operating hours and ton-hours for each of the three chillers. Determined that the retrofit was cost effective for two of the three chillers and cooling towers, but that the third chiller did not generate enough savings to be considered cost-effective.

Provided design phase document review and commissioning support for several LEED-targeted new construction projects. Such projects include a new office building for a leading pharmaceutical manufacturer and several large mixed use facilities throughout New England.

After completing his undergraduate and graduate work at Cornell and Harvard, Peter worked briefly in the petroleum industry. He quickly moved into the field of energy conservation by founding his first company, which specialized in residential energy audits and insulation retrofits. He subsequently ran the HVAC department at a major Boston engineering firm, and also served as a vice president for an outfit that specialized in energy conservation in the healthcare environment.

Peter quit working for "the man" in 1989 when he founded DMI, initially working out of his attic. He quickly expanded operations, developing DMI into one of the most respected energy engineering firms in New England. After running the company for 15 years, he turned the reins over to Alec Stevens in January, 2005. Peter continues to serve DMI as a part time consultant, and is a valuable mentor to junior engineers.

In his time away from DMI, Peter has a strong interest in making the world a better place for all. He serves on the board of directors of local non-profits that range from interfaith outreach programs to organic gardening co-ops. Peter also enjoys backpacking and canoeing, and has spent portions of the past several summers hiking in the Pacific northwest and relaxing in Northern Maine.

Eric completed his undergraduate studies at Swarthmore College. He then volunteered for service in the Peace Corps, and spent time in Mauritania working on public health education and rural infrastructure development. After returning to the states, he gained experience in the construction industry as a geotechnical field engineer. He came to DMI in 2000, and has enjoyed an ever-increasing set of roles and responsibilities. When away from DMI, he enjoys canoeing, gardening, homebrewing, and the occasional trip back home to the Toledo area. In 2003, he took an extended vacation to tour New Zealand and parts of Asia on a bicycle. Eric will be implementing various energy efficiency strategies learned on the job as he renovates a recently-purchased house.

Key Projects
Post-installation studies for regional utilities that compare pre-installation estimates of energy savings and demand reduction to actual values. Sites have ranged from ski slopes to plastics manufacturing, high-efficiency rooftop units to industrial refrigeration. Requires a high degree of accuracy in calculation methodologies and the acquisition of operating characteristics through long- and short-term metering, trend log data reviews, and site interviews. These projects occur on an annual basis.

Commissioning and modeling services for LEED accreditation. Projects include a large biotech facility in Boston and an art museum on Cape Cod.

Modeling services in support of regional utility pilot studies for the introduction of the Advanced Buildings Benchmark design guidelines. Facility energy models were compiled using spreadsheet bin models that allowed up to twenty different design alternatives to be modeled interactively.

Mickey came to DMI from the Syracuse University Industrial Assessment Center. He serves DMI as a project manager for municipal, commercial, and industrial retrofit and new construction projects. While away from DMI, he is an avid baseball fan and runner.

Provided coordination and leadership for the construction-phase LEED commissioning activities for a new high-rise green residential building in Boston.

Modeled energy consumption and savings for the major systems renovation at a leading pharmaceutical manufacturing facility. This included automation of a water-side free-cooling system, variable speed drives on air handlers allowing for HEPA constraints, upgrade of chilled water system including chillers and pumps, and occupancy control of lab space ventilation.

Wrote site evaluation plans, visited facilities to collect information and metering data, completed analysis, and authored evaluation site reports for HVAC and process impact evaluation studies. Coordinated and managed study completion for several evaluation sites.

Jay graduated from UMass Amherst and has previous experience in the design of electrical connectors and switches. Since coming to DMI, Jay has developed strong experience in HVAC and industrial process energy analysis. He serves DMI as a project engineer for municipal, commercial, and industrial retrofit and new construction projects. While away from the office, Jay is an avid cyclist and skier. He also participates competitively in canoe racing.
