The insulation experts that comprise the Insulation Institute provide many decades of knowledge that helps inform the Institute’s many educational activities. While insulation experts, many have expertise that extends into other areas of building science. Insulation expertise is good, but buildings are systems, and these experts understand the interplay of the many components of homes and buildings.
Johns Manville | Building Scientist
As a building scientist for Johns Manville, JR is responsible for research and technology development of building products and applications, with emphasis in building science, indoor environmental quality and energy efficiency.
He has been with Johns Manville for 16 years. He is actively involved in standards development through ASHRAE, represents Johns Manville on industry and government research teams and serves on the Board of Directors for Home Energy magazine.
He holds a Master’s degree in engineering and a Bachelor’s degree in physics from the University of Colorado and is also a licensed engineer.
Clarke Berdan II
Owens Corning | R&D Leader
Clarke Berdan II, Ph.D., received his doctorate degree from the California Institute of Technology majoring in Chemical Engineering and BS degree from the University of California at Berkeley in the same discipline.
He has been with Owens Corning at the Science and Technology Center since 1981 and is currently the Senior Technical Services Leader for the insulation products businesses. His group operates under the umbrella of the Corporate Sustainability organization and thus provides the businesses his team supports with a view to products and applications through the lens of sustainability. His group is very active in industry product and testing standards and code language development.
His experiences cross a wide range of product and process development as well as process and building modeling. Much of his work has focused on the understanding of the physical operations of building envelopes from the theoretical through to the practical aspects of the transport phenomena that exist out in the built environment.
Product development is very important, but to enhance the success rate, it must come from a systems approach that understands what problems are needed to be solved and how products work as integral parts of systems over their useful service life.
Clarke currently serves on the board of directors for the Air Barrier Association of America.
NAIMA | Vice President, Technical Services
Charles Cottrell is the Vice President of Technical Services for the North American Insulation Manufacturers Association, the association that represents fiberglass, rock and slag wool manufacturers.
He is responsible for identifying opportunities which improve building energy efficiency, creating regional networks and implementing activities in the areas of building energy codes for new and existing homes.
Prior to joining NAIMA in 1998, Charles worked for the National Association of Home Builders and a mechanical contracting firm where he designed and oversaw the installation of commercial HVAC systems. He has owned a construction company that did residential construction and commercial building maintenance. Upon graduating from Virginia Tech where he received his B.S. in mechanical engineering, he served in the U.S. Air Force as a pilot for eight years.
CertainTeed Corp. | Manager, Building Science Applications
Lucas Hamilton is Manager, Building Science Applications for CertainTeed.
He’s spent more than 20 years in the building science end of the construction industry, working for builders, designers and product manufacturers. He brings an in-depth knowledge of the physics of buildings to the practice of building.
His experiences include forensic building envelope diagnostics and testing, development of non-intrusive construction analysis equipment and techniques, research and development of construction materials, and he is a practitioner of a variety of building performance simulation software.
Lucas is a frequent presenter of programs that span the breadth of Building Science topics. In his years with CertainTeed, Hamilton has spoken to more than 1,000 different groups ranging from individual local architectural firms to national architectural firms to AIA, AIBD, SARA and CSI chapter events to statewide AIA and CSI chapter events to the national AIA and CSI conventions in both the US and Canada.
He has presented education programs to specialty subcontractors as well as to general contractors throughout the US. Twice a year he provides a weeklong series of continuing education programs for building code official and contractor licensing programs in the Mid-West.
Knauf Insulation | Director of Sustainability
Scott Miller is the Director of Sustainability and Product Affairs at Knauf Insulation.
He is responsible for Knauf’s external relations with agencies, key standard-setting organizations and interest groups. His areas of interest include promoting sustainable development, the value of energy efficiency and the fair and balanced performance of all genres of insulation products.
Scott is past chairman of the Sustainability and Environment Committee of the North American Insulation Manufacturers Association, as well as serving on the Regulatory Affairs Committee. He is also active with BIFMA (Office Furniture Association), ASHRAE (past Chairman of Chapter 23–Mechanical Insulation–Fundamentals Handbook), the GREENGUARD Environmental Institute, the U.S. Green Building Council, ASTM and others.
A mechanical engineer with more than 30 years of product assessment and testing experience, Scott is particularly interested in elevated temperature performance and sustainability in insulation. His recent work with Knauf includes an emphasis on environmental issues, as the industry works to promote insulation’s role in reducing energy consumption and preserving our natural resources, while maintaining comfortable and healthy indoor environments.
Shriver Consulting | Principal
Jim Shriver was with Thermafiber/USG for 35 years and currently owns Shriver Consulting Services.
He has held positions in the manufacturing of mineral wool including Plant Manager, Quality Manager, Production Manager and Engineering Superintendent. Those skills allowed him to provide trouble shooting for other USG mineral wool facilities. During the last fifteen years in the industry, he developed Thermafiber’s Technical Department following USG’s sale of the Thermafiber Division and held the position of Director of Technical Services.
Jim’s key expert knowledge includes all fire and acoustical testing, product compliance to published data and system designs for perimeter fire containment that includes several patents. He remains active in ASTM International including committees C 16 on Thermal Insulation and E 05 on Fire Standards. He is currently active in writing the standard for perimeter fire containment due to leap frog and ASTM E 2307 on perimeter fire containment.
Included in his role at Thermafiber were the US Building Code activities (IBC), participating member in the FCIA, IFC, NFPA and NIA. He has published several articles and given numerous talks on perimeter fire containment and mineral wool. He welcomes any questions on mineral wool including technical issues, fire containment, sound control and manufacturing capabilities.
