#14- 2026 - Carl Grimes Director of the Hayward Healthy Home Institute

Hayward Score Healthy Home Director Carl Grimes, has a unique combination of experiences. He has personal experience of the disabling impact of an unhealthy home, and professional experience working in the Indoor Air Quality field. Both these experiences lead him to the Hayword Score where they are helping people live healthier lives by first believing in the negative health experiences they are having in their home, and second by offering a tool that can help homeowners understand these experiences. Carl understands that moisture and mold are not the only things that lead to poor indoor air quality and is trying to work out the synergistic interactions between occupants, house, and building science that can result in either a health supporting or health degrading environment.Carl Grimes on LinkedInHayward ScoreIndoor air quality Association The Quick Environmental Exposure and Sensitivity Inventory(Symptom Star)ASHRAE Guideline 10-2023 -- Interactions Affecting theAchievement of Acceptable Indoor EnvironmentsToxicant-Induced Loss of Tolerance (TILT) - ChemicalIntoleranceInstitute of Inspection, Cleaning and RestorationCertification (IICRC)ANSI S520-2025 Standard for Professional Mold Remediation
