Our Mission

"We at Pacific Solar Radiant Inc. are committed to the hightest quality design and construction practices so the final product exceeds the expectations of the client.

We share our years of experience so that there is a seamless integration of the heating and plumbing systems."


Pacific Solar Radiant Inc. was founded by William Shady P.E., Professional Mechanical Engineer, and Greg Cross, a licensed Plumbing Contractor, to create a design/build company to meet the needs of the discriminating client who wants the highest quality product possible for their Homes and Commercial Buildings.

We are Mechanical Engineers and Plumbing Contractors with over 50 years of combined experience in the industrial, commercial and custom residential markets.

All of our design/build projects are complete with design drawings signed and stamped by the principal mechanical engineer, and managed in the field by a principal so that decisions can be made quickly and efficiently.

We are experts in the integration of all of the environmental systems so that the client can simply enjoy their controlled environments without effort.

As many design professionals are aware the early planning phases of a major project is the time to have the mechanical engineer provide support for the plumbing and mechanical systems. We provide design development and schematic design support for our projects and contribute valuable budgetary input so that cost estimates can be realistic and decisions can be made based on our experience and past project costs.

Our design input and expertise in Title-24 Energy Compliance Analysis give the Architect the tools to perhaps incorporate more glazing and natural lighting, ensure a comfortable heating system to use more natural and sustainable materials, and the most efficient life cycle cost heating and cooling systems.

Construction drawings are produced early and are used by the Architect and builder to coordinate utililties, thus maximizing the conditioned areas.
