R. Christopher “Chris” Mathis has spent the past 30 years focusing on how buildings and building products per-form – from energy efficiency to code compliance to sustainability and long-term performance durability.
Chris received his undergraduate degree in Physics from the University of North Carolina at Asheville. He received a Master of Science in Architecture Studies from MIT where his graduate work focused on energy use in buildings. He has served as a Scientist in the Insulation Technology Laboratory at the Owens-Corning Fiberglas Technical Center, was the Director of the Thermal Testing Laboratory for the National Association of Home Builders Re-search Center, and Director of Marketing for Architectural Testing, Inc., a private laboratory specializing in the performance of buildings and building products, particularly fenestration performance testing.
Chris is an active participant in Standards and Code development at ASHRAE, NFRC, ASTM and the ICC. He was a founding member and served for four years as the first Director of the National Fenestration Rating Council, the non-profit organization that developed the nation’s energy performance rating and labeling system for windows, doors and skylights.
Chris is a 30-year member of the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE). In ASHRAE he has worked on window thermal test standards, national model codes for commercial buildings (ASHRAE 90.1), model codes for residential buildings (ASHRAE 90.2) and is the energy consultant to Standard 189.1 – ASHRAE’s model code for sustainable commercial buildings. He is also the energy consultant to the Chapter Technology Transfer Committee.
Chris has been recognized as an ASHRAE Distinguished Lecturer, conducting seminars on a variety of building science, energy efficiency and sustainability topics across the US and worldwide. Chris has published numerous technical papers at ASHRAE and presented his work at a variety of national and international conferences. His publications include technical papers on: advanced test methods for insulation materials and wall systems; daylighting design and assessment techniques; off-peak cooling techniques for commercial office buildings; new residential and commercial energy codes; and metrics for environmentally preferable products. He has written numerous engineer-, architect-, builder- and consumer-targeted articles and guides on various building and product performance issues. He is the author of Insulating Guide – a book for home builders providing insulating best practices for many of the most common home building details. He is the co-author of Is Your Home Protected from Water Damage? A Homeowner’s Guide to Water Damage Prevention published by the Insurance Institute for Business and Home Safety.
Chris has been involved in state and national code development since 1988. He was selected four times to serve on the International Energy Conservation Code Committee of the ICC, working to refine and improve the IECC – our national model energy code. He was also selected to be a member of ICC’s Sustainable Building Technology Committee helping to draft a national model code for sustainable buildings. He served on the ICC’s first Code Development Committee for the International Green Construction Code.
Chris provides a number of accredited training seminars for architects, engineers, builders, manufacturers, code officials, utility program developers and others addressing these myriad building science and building performance issues – from improved building energy efficiency and comfort to energy and power planning to improved building and energy codes to the challenges of sustainability and green building. He is a frequent keynote speaker at various national conferences and events. Chris is also an on-going student of about 90 million years of sustainability and building science through his activities as a beekeeper. He lives and works near the farm he grew up on in the beautiful mountains of Western North Carolina.
