1 Using Building Science to Reduce Weather-Related Losses Greater Tampa Bay ACP Chapter Meeting May 30, 2012 Chuck Miccolis IBHS Commercial Lines Engineer & Gail Moraton IBHS Business Resiliency Manager

2 IBHS Mission: To conduct objective, scientific research to identify and promote effective actions that strengthen homes, businesses, and communities against natural disasters and other causes of loss. How does IBHS advance the cause of loss mitigation? Conduct building science Identify mitigation solutions for all aspects of the building chain Improve public policy Develop voluntary standards and guidance

3 IBHS Focuses on Building Performance Chain Where You Build How You Build Retrofitting How Well You Maintain & Repair Location & Risks Design Construction & Installation Maintenance & Repair Building Codes and Enforcement

4 Rising Above the Roar: Making Mitigation Matter

5 Don t Just Tell Me, Show Me Visual Evidence Sticks

6 Game Changer: The IBHS Research Center Public, applied science Highly realistic, full-scale testing Residential and commercial programs Multiple hazards (wind, rain, fire, hail) Private/public/academic partners

7 Foundational Research WIND Getting the science right RAIN WILDFIRE

11 Rooftop Equipment

12 Next Up: Solar Arrays

13 2012 Hurricane Season Demo: Typical Strip Mall-Type Building Two 30 ft. by 20 ft., 1-story masonry specimens placed side-by-side on the turntable in front of the fans. Test will highlight several common failure points: Perimeter Edge Flashing Non-continuous load path Ballasted roof-mounted equipment Overhead roll-up door Effects of over pressurization of the building

14 Don t Just Tell Me, Show Me Visual Evidence Sticks VIDEO Water Intrusion Testing Click here for video

15 Wind-Driven Water Intrusion Research Duplex damage estimates Unsealed roof deck side = $16,935 Sealed roof deck side = $5,408

16 Two Part Closed Cell Polyurethane Foam Install along plywood seams prevents water intrusion Adhesive Install along roof sheathing to the roof framing adds strength against uplift Contractor needed

17 Water Intrusion

18 Shingle Repair Shingles - spend $4 on a 10 oz. caulk tube of roofing cement 1 tube = 25 feet of shingles Focus on shingles near the roof edges and near gable ends Place adhesive under each shingle tab (near the edges and in the middle). On gable ends, secure the three shingle tabs closest to the gable edge. Doing this Helps you avoid this

19 Soffits Soffits - Spend $6 for 10 oz. of polyurethane sealant Apply a bead along the joint between the edge of the channel and the wall; Install sharp pointed stainless steel screws through the fascia and channels so that they connect the soffit material; Apply sealant in the grooves where the fascia material butts up against the fascia and wall channel OR

20 Sealants Seals - Spend $2 on 10 oz. of caulk and use to seal: Openings where utilities, wires, & cables enter and exit the building Electrical boxes and circuit breaker panels; AC refrigerant lines, AC condensate lines, water pipes; Cracks around wall outlets & vents Doing this Helps you avoid this

21 Window Protection IBHS Shutter Selection Guide - available at disastersafety.org Large / Small Missile Impact Resistant Window & Frame Systems, Shutters, fabric and screen panels,½ - ¾ in. Plywood Use products Tested / Approved for your area Florida Building Code Testing Application Standard (TAS) 201, 202 and 203 / Miami-Dade County Notice of Acceptance (NOA) American Society for Testing and Materials (ASTM) E 1886, ASTM E 1996, and ASTM E330 FM Global Approval Standard 4350

22 Commercial Overhead & Garage Doors Age of door, look for a label for wind rating Replace with a hurricane resistant door - Tested / Approved for your area Florida Building Code Testing Application Standard (TAS) 201, 202 and 203 / Miami-Dade County Notice of Acceptance (NOA) ASTM E 1886, ASTM E 1996, ASTM E330 For Garage Doors Only: ANSI/DASMA 115 Bring up to current standards using horizontal and vertical struts, additional track brackets, and longer rollers

23 Commercial - Roof Covers Implement periodic roof inspections & repair plan Repair roof leaks / bubbles / wet insulation Check all penetrations Remove loose objects Remove loose pea gravel Check gutters When replacing Roof Covers (2.0 safety factor) FM Approved Miami Dade County NOA Split Seams, Worn Cover Bubbles

24 Commercial Roof Edge Flashing Poorly attached flashing / drip edges & gutters Replace ANSI/SPRI/FM4435/ES-1 To Repair Space screws 12 to 16 in. o/c, approx. Use epdm or neoprene washer Lower portion of flashing screws

25 Roof Mounted Equipment Proper Securement Connect with ¼ in. steel cables & turnbuckles to structural component of roof system Repair loose panels and equipment screens Satellite Dishes

26 IBHS Maintenance Matters Series Age of HVAC Systems and New Technology HVAC seasonal checklist Hiring an HVAC professional Steps to protect vacant commercial property Water damage prevention for commercial buildings Commercial Electrical Safety Preventing Electrical Surge Hiring a Professional Electrical Contractor

27 IBHS Voluntary, Superior Construction Standards

28 FORTIFIED for Safer Living Homes Pre-Hurricane Ike Bolivar Peninsula, Texas FORTIFIED for Safer Living Homes Post-Hurricane Ike Bolivar Peninsula, Texas

29 FORTIFIED for Safer Business Natural Catastrophe Risks Hurricane High Wind, Tornado and Hail Wildfire Severe Winter Weather Flood Earthquake

30 Severe Weather Emergency Response Planning Keys to Success Overcoming two fatal mistakes Failing to understanding the hazard Underestimating the exposure Documented with designated responsibilities Protection of building, business functions, utilities Periodic training Exercises Various alert levels Material supply checklist Feedback Process

31 Hurricane ERP Prepare for 1 Category greater than weather service prediction Wind and / or flooding storm surge Building Envelope & Utilities Alert Levels Offseason activities (materials procurement, training, asset inspections / repairs) Impending storm (72, 48, 24, 12 hours) Feedback

32 Flood / Storm Surge ERP Determine your Hazards FEMA Maps Evacuation Maps for your area - (Storm Tide Atlas) If in an evacuation area, then storm surge Local Area Flood Protection such as Levees and Dams How-To DISASTERSAFETY.ORG

33 Storm Surge & Flooding Dry Flood Proofing Protection Permanent or Moveable: Doors, Gates, Walls Water or sand filled barriers Sandbagging Shallow depths; Much work Floor Drain Plugs / prevent back flow Sump pumps

34 Storm Surge & Flooding Utilities Electrical Indoor and Outdoor equipment such as Transformers, Switchgear, Generators, Fire Pumps / Controllers, etc. Raise above expected flood level, include a safety factor Provide protective enclosure Provide reinforced flood walls if can not raise Include back up power in protective planning Seal penetrations coming into buildings around utilities

35 Storm Surge & Flooding Utilities Potable Water Provide alternative water source Storage tanks Freshwater wells with well head above flood levels Stored Bottled water Waste Water Prevent Sewage Back Up Backflow Preventers Prevent open pits from backing up into the building Onsite lift stations connected to back up power
