Who We Are
McClure Engineering has had a leadership role in advancing the technology in comfort environmental systems. We authored the first commercially available diagnostic computer programs to analyze building energy consumption. Other innovations included variable air volume system designs in the late 1960’s, engine driven water source heat pumps with engine heat recovery, internal combustion engine cogeneration systems, one-pipe campus type chilled water systems and variable flow chilled water systems. The firm has a strong belief that energy conservation is an ethic that should permeate all aspects of mechanical and electrical system designs.
Led by a group of seasoned professionals with both breadth and depth of industry knowledge, our firm partners with building owners, architects and facilities managers to design and maintain building systems. With a focus on institutional, educational, and industrial facilities, quality engineering is key as our projects are designed to last.
