Julia Keen

Julia Keen, an architectural engineer, designs mechanical and electrical systems for new and retrofit construction ranging from hospitals to office buildings to churches. Recognizing her valuable industry experience and its importance in the classroom, Kansas State University hired her last year to teach while she is working on her master of Science in Architectural Engineering.

As a mechanical/electrical project engineer, Keen worked at Gilmor & Doyle and at Kapaun Consulting Engineers managing multiple projects from the initial planning stages with the architect and owner through design, biding and construction. She designed systems from the initial determination of the system type and size to the selection and specification of each of the system components and the system layout. In addition, Keen created life-cycle cost analyses and building thermal load analyses. She served as chapter officer for three years and recently completed her term as president of the Cedar Valley Chapter of the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE).

Phichai Kritmatree
Mechanical Engineer

Phichai Kritmatree, a professor of mechanical engineering at Kasetsart University in Thailand, teaches courses in fluid machinery, refrigeration and air-conditioning.

As a research student for his doctoral degree at the Japan Atomic Energy Institute he studied liquid hydrogen circulation for the cold moderator system. He presented a paper on the analytical results of the suction process of a volumetric scroll pump that will be developed for circulating liquid hydrogen in a cold moderator system. The analytical results show that at the end of suction process the relative pressures increase significantly in a pocket while decreasing continuously in another pocket. This phenomenon might damage scroll pump components if the high-pressure side is too high and/or the low-pressure side is too low until the cavitations occur. Therefore the pocket should open to the discharge chamber before it closes and separates from the suction chamber in order to prevent the cavitations and extremely high-pressure regions.

Louis Molinini
Mechanical Engineer

Louis Molinini, a mechanical engineer at Syska Hennessy Group Inc. in Fairfax, Virginia, designs heating, ventilating and air-conditioning (HVAC) systems for both the private and public sector.

Molinini is responsible for preparation of HVAC design calculations, construction drawings, and specifications. He has designed systems for critical online environment facilities and federal agency headquarter facilities. As a LEED™ (Leadership in Energy and Environmental Design) accredited professional, Molinini has consulted on the various aspects of sustainability, commissioning and energy analysis and design to various federal government agencies. He has completed studies on the optimization of air handling unit sizing and selection as well as an energy analysis of the effects of the latest building energy codes on new building design.

R. Bradley Boutilier
Mechanical Engineer

R. Bradley Boutilier, a mechanical engineer at Henry Adams, Inc., in Baltimore, Maryland, designs systems tailored to meet a wide variety of public needs.

Boutilier engineered the mechanical systems for a 340,000 square-foot addition to the Baltimore County Detention Center integrating special security and life safety requirements. While working on the 17-acre Washington Convention Center, he provided on-site project review and construction coordination. Boutilier has been design engineer for the historic Mount Vernon Inn and the mechanical systems engineer for the renovation and addition to the Brandywine River Museum in Pennsylvania. Currently he is engineering an acoustically-sensitive new music and arts center for Washington and Lee University.
