  1. What is the IMPACT Internally and for Contractors? New FL MOLD Bill Lesley.Welch@disney.com 407-397-6516

  2. Mold-Related Services Licensing Unit Senate Bill 2234, enacted June 27, 2007 as Chapter 468, Part XVI, Florida Statutes, July 1, 2010 http://www.myfloridalicense.com/dbpr/pro/mold/index.html

  3. What Happens July 1, 2010 • Grandfathering • Initial Licensing • Enforcement • Licensed Contractors

  4. Written Mold Program? • What is development objective? • Water Intrusion • Mold Remediation • Remediation Employee Training • PPE • Containment • Protect the health and safety of the building occupants and remediators.

  5. Resources • IICRC Guides http://www.iicrc.org/iicrcstandards.shtml • Carpet Cleaning S100 • Water Damage S500 • Mold Remediation S520 • EPA Mold Guide • Checklist for mold remediation

  6. EPA Mold Course - online • Introduction to Mold and Mold Remediation for Environmental and Public Health Professionals

  7. Mold Training

  8. IH Support at WDW • Water Intrusion • Mold Assessment • Remediation Plan • IAQ Complaints Paradigm Shift • Microbial Air Sampling Visual - IR & HVAC

  9. Invaluable Tools: IAQ investigation • IR Camera • Wet Wall Meter • HVAC/IAQ air sampling • T° • rH • CO • CO2 • VOC’s • Respirable aerosols

  10. IR Training http://www.infraredtraining.com/courses/building_sciences.asp

  11. Moisture – Building Enclosures - Mold How water gets into a structure, why it doesn’t leave, and how these architectural flaws become HVAC headaches. • Design Flaws • Poor drainage • Leaky envelopes • Construction materials don’t shed water • Pipes in exterior walls - sweating

  12. Groundwater, slopes & Irrigation

  13. Plumbing Hidden Moisture

  14. Going Green EfficientBldgs = Reduced Energy Exchange = Mold, part load humidity problems, rot, & corrosion. • Reduced Energy Exchange • AC runs less • Drying can not happen without exchange of energy. • Separate System • For Sensible load & Latent Load • Pre condition make up air • Cooling with reheat • Independently control • T, rH, & air flow • When AC turns off at night does humid air still enter?

  15. Hot Humid Climates • Insulate on outside • Back ventilate and drain cladding • Separate sensible load from latent load • Don’t over ventilate • Pressurize 2-5 pascals with conditioned air (except indoor pools, kitchens) • Watch for continuous exhaust fans

  16. Expansion Joints & Flashing

  17. Vapor Barriers – hot humid Incorrect use leading to increase moisture related problems. Function of VB retard migrations of water vapor. Location & permeability function of climate, characteristics of assembly materials, & interior conditions. • Not intended as Air Barrier • Supposed to prevent assemblies from getting wet, but often prevent assemblies from DRYING • “Double” vapor barriers • Wall paper • Vinyl flooring

  18. Vapor Barriers

  19. Role of Architect, Contractor, HVAC Engineer • Keep rain /groundwater out • Let it dry if it becomes wet • Make it tight • Pressurize • Ventilate – control humidity

  20. Glazing and sealants

  21. Remediation Plan What do you do with GWB? Should you use BLEACH? What about KILZ paint? • BLEACH • KILZ Paint • Acceptable Coatings: • Permawhite • Mil-Kil • Portersept • M-1 Additive

  22. Conclusion • Written Program • In House: • Training and Tools • Contractors: • Ensure Licensure
