Lead Responsible Engineer, Mechanical, Primera Engineers; BS, Mechanical Engineering, University of Wisconsin-Madison
With a decade of experience in design engineering and project management, Stephen Wisniewski collaborates with interdisciplinary teams to specify equipment selections that meet system load requirements. His expertise includes heating, ventilation and air conditioning (HVAC) system design for hydronic and airside systems, along with the layout of ductwork, piping and major equipment like pumps, boilers, condensing units and air handling units. He also leverages his extensive knowledge of codes and standards to serve as a third-party permit reviewer for major municipal building departments. He has worked on many complex projects in and around Chicago. For the Cook County Enhanced Visitation Center, he was responsible for mechanical system design that aligned with aggressive energy-performance and sustainability criteria, integrating high-efficiency HVAC systems, advanced heat-recovery strategies and optimized control sequences to minimize energy demand while maintaining strict thermal comfort requirements. He also served as lead mechanical engineer for ComEd control buildings that support critical electrical infrastructure and require systems designed for safe, reliable and continuous operation of the power grid. Earlier in his career, Wisniewski worked on automated warehouse logistics systems and later transitioned to HVAC design and project management, coordinating permit reviews, managing project documentation and supporting capital development board projects through design and construction phases. Personal projects include volunteering with the Metro Chicago Chapter of Rebuilding Together on National Rebuilding Day, helping repair and renovate homes for families in need. He also mentors students through the Mentor Matching Engine program and enjoys electronics projects, 3D printing and spending time with his agility dog, Spud. He and his wife welcomed a baby boy in March.
