This week we welcome back a long time friend of the show Carl Grimes of Hayward Score. Many of our listeners know Carl has been an advocate for including health in IEQ assessments for years and has been working with sensitive people for decades. Recently Carl worked with ASHRAE to better define health. He also spoke at IAQA on including people in assessments. In addition, Carl has extensive insight into the IICRC S520 over the years and has some thoughts on the latest proposed revisions.

Hayward Score Healthy Home Director Carl Grimes, HHS CIEC, has a unique combination of experiences. He has both the personal experience of how an unhealthy home created his disabling impact, plus the professional experience in various industries working in the Indoor Air Quality (IAQ) field. Carl wrote Starting Points for a Healthy Habitat in 1999, detailing possibilities of what could occur in a house to make its occupants sick, how to identify what was happening, what to do about it, what not to do, and how to verify the results.

The book led to an invitation to speak at the national conference of the Indoor Air Quality Association, which led to an invitation to serve on a committee that wrote the first mold remediation standard. This was followed by revising the ANSI accredited water damage restoration standard, duct cleaning standards for two organizations, fire residue in HVAC systems, and eventually to the creation of IAQA’s Home Health Committee. Under his leadership a new course was developed in partnership with the National Center for Healthy Housing and Children’s Mercy Hospital in Kansas City: Healthy Home Assessment: Principles and Practice. Other activities included serving on the Board of the International Society of Indoor Air Quality and Climate (ISIAQ) as the Vice President of Practice, on the ethics committee of the International Society of Environmental Epidemiology (ISEE), the Joint Task Force workgroup of the American Academy of Allergy, Asthma, and Immunology and the American College of Allergy, Asthma, and Immunology (AAAAI-ACAAI). The latter developed four medical practice parameters for allergists plus an entire issue of a leading peer reviewed journal on mold. He was on the committee that wrote the ASHRAE Position Document on Limiting Indoor Mold and Dampness in Buildings.
