Introduction

William R. Acorn is principal and founder of Acorn Consulting Services. For over 40 years, he has been involved in the analysis and design of hundreds of projects ranging from institutional laboratories to cleanroom facilities for the semiconductor industry. His active consulting practice involves all aspects of project delivery in the built environment, including code compliance for controlled and hazardous environments. He has received numerous awards for technical excellence and is recognized for his technical achievements, innovation and foresight by peers, associates and clients in the advanced technology industry.

Mr. Acorn has significant experience as an expert analyst of system design, system failures, code compliance issues and cause/effect relationships of problems related to the built environment. As a forensic analyst and expert witness, Bill has represented both plaintiffs and defendants in a variety of jurisdictions. Forensic assignments include projects dealing with HVAC systems, alleged exposure to chemicals via industrial ventilation systems, refrigeration systems, design and construction of cleanrooms, fires and explosions, pressure vessels, pipelines, exposure to Legionella bacteria, and various types of product liability.

Mr. Acorn’s experiences as a mechanical engineer, project manager and design firm principal span the range of engineering endeavors including programming, conceptual design, facility evaluation and optimization, design for construction documents, start-up and commissioning and construction phase support of contractors. Mr. Acorn has been personally responsible for the design and analysis of HVAC systems, cleanrooms and critically controlled environments, industrial ventilation systems, process piping systems, energy management/control systems and commercial/industrial refrigeration systems. Utilizing his experience in design and design firm management, Mr. Acorn focuses much of his practice on design consulting, acting as an owner’s agent or extension of the staff of the designer/builder of complex projects. In the role of design consultant, Mr. Acorn’s proactive approach includes review of the design of engineers or contractors, code compliance consulting, value engineering, sustainability evaluation and performance optimization suggestions to owners and design/build teams.

As the author of the book - Code Compliance for Advanced Technology Facilities, Mr. Acorn is widely recognized as an authority on the subject and regularly delivers seminars and workshops to industry and academia on hazardous occupancy code compliance. Mr. Acorn regularly consults with the regulatory community concerning issues of life safety in semiconductor and similar facilities. In addition, Mr. Acorn was a contributing author to the Semiconductor Safety Handbook edited by Richard A. Bolmen, Jr.

Mr. Acorn has been involved since the inception of the organization known as CREATE “Construction Research and Education for Advanced Technology Environments” at Arizona State University. This organization is charged with research and development related to the design and construction of advanced technology facilities such as semiconductor, biotech, pharmaceutical and nanotechnology. As an Adjunct Professor in the Arizona State University Del E. Webb School of Construction, he delivers seminars several times a year through their continuing education program on topics including design, project management and code compliance for advanced technology facilities.

Registered as a Professional Mechanical Engineer in the States of Arizona, California, Colorado, Illinois, Iowa, New Mexico, Nevada, Oregon, Texas and Utah, he is also registered with the National Council of Examiners for Engineering and Surveying.
