Our design philosophy expands TMP’s services beyond traditional boundaries. We have cultivated a sensitivity for client and market priorities in all facets of the building services mechanical engineering field. Project types include a broad spectrum of commercial, high rise, institutional, retail, and industrial applications of all sizes. Recognized as an industry leader, we design energy efficient mechanical systems including the development of original central heat pump chillers, hot and cold thermal storage, compartmentalized VAV air conditioning systems, and office underfloor air distribution. Our close association with the construction and building operations components of our industry provides valuable feedback, giving us unique insight into the effectiveness of our efforts and allowing us to continuously upgrade our familiarity with, and understanding of, our increasingly complex specialty. We have contributed to the evolution of mechanical systems design through the transfer of advanced technologies from our worldwide portfolio, to encourage the adoption of innovative practices on all our projects. Our 60 years of experience across North America has allowed us to develop respect for other social and technical cultures. We research new and proven opportunities, listen to our clients’ needs, and investigate local conditions before arriving at recommended design solutions.
