Florida Department of Agriculture and Consumer Services Adam Putnam COMMISSIONER Pest Management and Green Building Rating Systems
Pest Management Requirements for LEED v4 Credits LEED v4 includes updates to these rating systems: LEED for Existing Buildings - Operations and Maintenance LEED for Homes Proposed credits more in line with EPA IPM policy/green Pest Management Standards Proposed credits need to be adopted by USGBC
Existing Buildings: O&M Indoor Environmental Quality (EQ) EQ CREDIT: INTEGRATIVE PEST MANAGEMENT EB:O&M - 2 points Existing Credit Intent To reduce levels of chemical, biological and particulate contaminants that can compromise air quality, human health, building finishes, building systems and the environment. Proposed Credit Intent To minimize pest problems and exposure to pesticides.
LEED 2009 for EB: O&M IEQ credit 3.6 IPM : least-toxic chemical pesticides, minimum use of chemicals, use of chemicals only in targeted locations and only for targeted species. Least-toxic pesticides are defined as those listed under Tier III of the City and County of San Francisco s SF Pesticide Hazard Screening List. Pest population monitoring, evaluation of the need for pest control and one or more pest control methods, including sanitation, structural repairs, mechanical and living biological controls, other nonchemical methods, and if nontoxic options are unreasonable and have been exhausted, a least-toxic pesticide. Universal notification to building occupants - which requires advance notice of not less than 72 hours before a pesticide under normal conditions and 24 hours after application of a pesticide in emergencies, other than a least-toxic pesticide
Proposed LEED v4 EB: O&M EQ credit IPM plan with these components: IPM Team with roles for building management, pest management contractors, maintenance staff, building occupants. Identification and monitoring of pests using inspections, pest population monitoring, and reporting of evidence of pest infestations. Action thresholds for common pests and a process for modifying action thresholds Nonchemical pest preventive measures either designed into the structure or implemented as part of pest management activities. Description of pest control methods to be utilized when action thresholds are exceeded.
Proposed LEED v4 EB: O&M EQ credit Preference to nonchemical approaches. If results unsatisfactory, application of pesticides registered for the site and pest to be controlled is permitted. Preference given to the use of Least Risk pesticides based upon inherent toxicity and exposure potential defined as registered pesticide in Tier III (lowest toxicity) category using the San Francisco Hazard Ranking system, or an insecticide sold as a self-contained bait, or a crack and crevice treatment used in areas inaccessible to building occupants Rodenticides are never considered least-risk pesticides
Proposed standard EQ O&M Allowance for use of pesticides not in category of Least Risk, provided reason for selection is documented. Documentation of inspection, monitoring, preventive and control methods and evaluation of the effectiveness of the IPM Plan. Record keeping and documentation required. A project meets the requirements if the IPM service is provided by a certified member in good standing of the GreenPro, EcoWise or GreenShield programs or a program with equivalent IPM standards, provided that the service provided complies with the respective program s standards.
LEED for Homes Sustainable Sites credit 5: Non-toxic Pest Control SS CREDIT 5: NON-TOXIC PEST CONTROL 0.5-1 point LEED 2008- Intent Design home features to minimize the need for poisons for control of insects, rodents, and other pests. LEED v4- Intent: To minimize pest problems and risk of exposure to pesticides.
LEED for Homes SSc5: Non-toxic Pest Control LEED 2008 No chemical pesticides for termite control, Use integrative pest management (IPM) Develop resident guidance related to pesticide use, housekeeping, and prompt reporting of pest problems to be included in the Homeowner Education manual for cockroaches, rodents, and bedbugs.
LEED for Homes SSc5: Non-toxic Pest Control Existing standard For termites: Install a steel mesh barrier termite control system. (1 point) Use solid concrete foundation walls, masonry walls with a course of solid block bond beam, or concrete-filled block. Install post-tension slabs and top feed utilities. Seal all external cracks, joints, penetrations, edges, and entry points with appropriate caulking. Install rodent- and corrosionproof screens (e.g., copper or stainless steel mesh), on all openings greater than ¼ inch, except where code prohibits their installation (e.g. dryer vents). Treat all cellulosic material (e.g., wood framing) with a borate product to a minimum of 3 feet above the foundation. Install a physical termite barrier system approved by code (e.g. basaltic rock).
LEED v4 for Homes Install a steel mesh barrier termite control system. Install a physical termite barrier system (e.g., basaltic rock) approved by code. For below-grade walls, use solid concrete foundation walls, masonry walls with a course of solid block bond beam, or concrete-filled block. Treat all cellulosic structural material (e.g., wood framing) with a registered pesticide containing borates, following the manufacturer s directions for preconstruction treatment. Use noncellulosic material for all structural elements. Install ports or openings for plumbing elements that penetrate the slab, to allow access for inspection and treatment of pest infestations.
LEED v4 for Homes Install a registered termite bait system/provide for ongoing maintenance minimum 6-inch inspection space between grade and nonmasonry siding. Seal all external cracks, joints, penetrations, edges, and entry points with appropriate caulking. Install rodent- and corrosion-proof screens (e.g., copper or stainless steel mesh) on all openings greater than ¼ inch, except where code prohibits their installation (e.g., dryer vents). Provide discharge points for rain gutters, air-conditioning condensation lines, steam vent lines, to discharge is at least 24 inches from the foundation. Leave a minimum 18-inch space between the exterior wall and any landscape plantings. Multifamily building projects develop an integrated pest management policy in the Homeowner Education Manual.
