Carl Grimes – Life and Times of a “Healthy Habitats” Pioneer

Air Date: 3-13-26 | Episode 774

This week we present another Life and Times show with Carl Grimes “Healthy Habitats” Pioneer. Carl wrote the book “Starting Points for a Healthy Habitat” in 1999 before people knew much about IEQ and its effects on people. His journey began when he suffered the affects of bad IEQ and could not find help. Since then he has written a book, volunteered with numerous industry associations and it has all culminated with his work as Managing Director of the Hayward Healthy Home Institute and Hayward Score.

Carl’s work focuses on people who feel better outside of their house or office, helping building occupants understand and improve their indoor environments — particularly for people experiencing health symptoms tied to indoor exposures like mold, volatile organic compounds (VOCs), and fragrances. Because he originally experienced indoor environmental harm in his personal life, he brings a unique perspective to understanding and communicating the complications between clients and practitioners. Carl is a frequent presenter nationally and internationally, past President of IAQA (Indoor Air Quality Association), and past Vice President of Practice of ISIAQ. He has served on and chaired committees writing ANSI accredited standards like the original IICRC-S520, chaired the IAQA Healthy Home Committee, and was a committee member on the ACAAI-AAAAI Joint Task Force that wrote medical practice parameters. He is immediate past chair of the ASHRAE TC1.12 Moisture Management in Buildings, and Guideline 10, Interaction Affecting the Achievement of Acceptable Indoor Environments, plus the ASHRAE position document Health and Wellness in the Built Environment.
