HVAC/Architectural Portfolio

"30 Years of using the latest in engineering technology, energy efficiency and environmental responsibility."

I am a licensed Professional Engineer in Georgia, Maryland, Delaware, Virginia and Pennsylvania and a LEED Accredited Professional. I am a member of ASHRAE and have been a correspondent with technical committee for Computer Applications(TC1.4). I am an expert in the design of building HVAC systems and plumbing, in building codes, automatic temperature controls, and building energy. I am a graduate of Miami University (Ohio) , 1977, and University of North Florida, 2000.

I was the Senior Project Engineer at my most recent position with TOLK, a subsidiary of Dewberry-Davis in Fairfax, Virginia. In this position, I was chiefly responsible for HVAC design and project management for large core and shell projects. Best practices for engineering and design are my forte, with an eye at all times on an optimal design for minimal energy consumption and ease of building and operating. My other recent energy work has included data collection, energy studies and recommendations for energy conserving measures on many various institutions.

I am also educated with work experience in architectural design and building preservation. I have renovated many residential buildings as owner-occupant, investor, and contractor.  I have fully renovated one early 20th century home and one 1950 home hands-on as carpenter and pipe fitter/plumber.

NOTABLE PROJECTS

One Justice Plaza, Washington D.C., New office building, 521,000 Sq. Ft.
Engineering of HVAC systems for the core and shell of a 10-story office building in an urban center. Responsible for calculations, design, coordination, and specifications including a 1400 ton central chilled water plant, chilled water distribution, condenser water loop and cooling towers. Airside design includes dedicated outside air systems in the penthouse with air-to-air enthalpy heat recovery feeding down to the rest of the building. Distribution ductwork used variable air volume and constant volume fan powered air terminals, with perimeter electric reheat. The use of variable speed pumps and fans, combined with larger temperature “deltas” resulted in a design which will easily meet or exceed LEED Gold certified levels of energy efficiency. Constructability, flexibility, and quality were also first priorities. (2007 TOLK)

Fort Belvoir Community Hospital, Central Utility Plant, Fort Belvoir, Virginia,  Steam, Chilled water and Power   
Prime engineer for heating including (4) high pressure steam boilers, 500 HP each, with dual fuel (gas/oil) burners, and steam and condensate return system piping.
