James Posey Associates is a consulting engineering firm based in Maryland. Founded in 1911, we provide mechanical, electrical, and plumbing engineering and commissioning services to support today’s sustainable high-performance building needs. More than 100 years of mechanical and electrical design excellence is a remarkable accomplishment by any standards, but at James Posey Associates, our successful history is never taken for granted. Whereas quality is too often thought of as just one of many components in the performance of professional services, we believe a total commitment to quality is the framework for the entire life of every project. We have the expertise required to engineer the project vision and support award-winning design, collaborating with the architect and owner to achieve the project’s goals.
