  3. About Us

Since 1930, van Zelm Heywood & Shadford, Inc has been devoted to the planning, study and design of mechanical and electrical systems for the built environment. With projects that range in size from small studies to significant designs, we work for clients that include internationally renowned architects, major corporations, and world-renowned institutions.

We bring the breadth and depth of our staff’s knowledge and experience to every project. Engineering design and consultation is our life’s work, but it is our client’s interests that we are dedicated to serve.

Long a proponent of sustainable design, van Zelm supports the growing global commitment to environmental conservation. We are proud to have contributed to the design of award-winning Living Building Challenge projects and LEED certified buildings that have verified Gold and Platinum level energy conservation and efficiency. We are proud to be a catalyst for the growth and education of our industry and for the users and operators of our built environment.

As the design of mechanical and electrical systems becomes increasingly complex, van Zelm can always be found at the forefront – merging imaginative solutions with the latest technologies and superior service.
