About Banner

Thomas A. Bathgate, PE, is President / CEO of PWI Engineering – formerly of Philadelphia since 1985 and recently branching into two offices – Cherry Hill, New Jersey and Jenkintown, Pennsylvania in 2013.

He has led energy conservation efforts on over five thousand building complexes continuously since 1973. His developments include inventive heat recovery concepts, alternative energy sources, and unique building energy concepts. He is an advocate for Green and Sustainable Building concepts and has led the design effort on several major building projects, in which environmentally friendliness and energy conservation were the key driving criteria. Research, computer modeling, and physical modeling have been used to promote and analyze concepts in passive solar design, daylighting, building thermal storage concepts, convective/raised floor concepts, solar air walls, geo-thermal heating systems, and active solar systems. Tom’s primary focus has been providing technological analysis and evaluations for alternative architectural components and systems, in the quest for eliminating or minimizing the need for energy driven lighting, heating and air conditioning.

He has also led the architectural engineering efforts on the design of renovation of many hospitals and complete new replacement hospitals throughout Eastern USA. In addition to the normal activities of a critical care hospital (surgery, ICU’s, and radiology), the hospital work has included specialized activities such as radiation therapy, specialized burn centers, specialized isolation for contagious diseases, and bone marrow transplant suites. Likewise with manufacturing facility design, including process services for the chemical industry, pharmaceutical industry, the aircraft industry, and the food industry. Facilities have included Class 10 cleanrooms up to highbay heavy manufacturing for die-casting. Most facilities have included flexible services for batch change operations. Pharmaceutical manufacturing spaces, all cGLP rated have included formulations (solids and liquids), tableting, encapsulation, filling (including sterile), parenterals, and packaging.

Commercial Office buildings bring a special element to the engineering and energy aspects of design. Tom’s focus on these building types has been the development of high reliability system concepts, low energy use concepts, organizing building communication systems and wiring systems into manageable entities, development of “smart building” concepts and application of “green and sustainable concepts”.

Tom’s second calling is in photography. His talents continue to shine though with his breathtaking photographs of the natural surroundings in his Pennsylvania homestead. They’re a good add in to any power point presentation.
