R. Christopher Mathis, ASHRAE
MC² – Mathis Consulting Company
R. Christopher “Chris” Mathis has spent the past 34 years focusing on how buildings and building products perform – from energy efficiency to code compliance to long-term durability. Today, his business focus is to work with strategically-aligned clients, leveraging that knowledge and understanding to improve buildings, building products and the codes and standards that govern them.
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 Research Center, and Director of Marketing for Architectural Testing, Inc., a private laboratory specializing in the performance of buildings and building products.
Chris 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 has published a variety of technical papers on topics including: 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 builder, architect and consumer-targeted articles and guides on 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.
Chris is an active participant in Standards and Code development at ASHRAE, NFRC, ASTM and the ICC. He served six years on the Board of Directors of the Energy and Environmental Building Association (EEBA). He has been 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. Chris is a member of the Board of Directors of BETEC – the Building Enclosure Technology and Environment Council. He is immediate past chairman of ASTM committee E60.01 on Buildings and Construction Sustainability and now serves as a Director on the Sustainability Executive Committee. He was a member of the ICC’s Sustainable Building Technology Committee helping to draft a national model code for sustainable buildings. Chris has recently 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.
Now, as president of Mathis Consulting Company (MC2), Chris and his team provides a variety of strategic services to both private and public sector interests related to buildings and building product performance. The MC2 team provides strategic support services to energy and building industry leaders – from trend analysis to code assessment to regulatory positioning. These efforts address product and building performance issues for new construction as well as for renovation, energy use and peak demand issues for utilities, meaningful sustainability metrics, as well as local, state and national regulatory planning. Chris and his team conduct frequent training seminars for architects, builders, manufacturers, code officials and others addressing these myriad energy and 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.
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.
Wiss, Janney, Elstner Associates, Inc.
Fiona Aldous is involved with commissioning and design peer review of buildings enclosures, commencing with the pre-design phase, design phase and extending through completed construction with on-site observation and performance verification. She has specific experience in the detailing and installation of various curtain wall and window systems, sloped glazing, air barriers, waterproofing of below-grade and plaza systems, low slope roofs, and the interfaces of the various enclosure components. She has performed investigations and condition surveys on numerous building types and a variety of building enclosure systems. Such investigations typically have resulted in the development of repair designs to remediate distressed and defective building enclosures.
