Barriers and incentives related to the installation of home fire sprinklers

  1. 1. Kathleen Almand- Executive Director<br />Barriers and Incentives Related to the Installation of Home Fire Sprinklers<br />
  2. 2. Fire sprinklers reduce fire death risk<br />All model safety and building codes require fire sprinklers in all new homes<br />Community based barriers<br />Additional benefits of sprinklers - water conservation<br />Incentives to increase use of fire sprinkler systems<br />Introduction<br />
  3. 3. Water usage and water meter performance during residential sprinkler system actuation in residences and to provide guidance information on this topic in a format suitable for water utilities and local jurisdictions<br />Residential Fire Sprinklers and Water Conservation<br />
  4. 4. Study of water consumption during fire events and resulting impacts on water infrastructure demand:<br />Estimation of water used per home fire by responding fire services<br />Calculations of the expected water discharged by fire sprinklers per home fire<br />Estimation of the reduced water infrastructure demand when fire sprinklers are present in all homes within a community<br />Study Tasks – Water Usage<br />
  5. 5. Water used by fire service:<br /> - Average of 3,524 gallons per fire<br /> - An approximate 10-times increase when<br />Fire extended beyond the room of origin<br />Increase of fire involvement from visible flame and smoke to fully-involved fire<br />Water Usage Results<br />
  6. 6. Related studies and results:<br />Scottsdale, AZ –Automatic Sprinklers: A 15-Year Study <br />-Average 2,935 gallons per fire used by fire services<br />-Sprinkler discharged up to 341 gallons per fire<br />Available here: http://www.homefiresprinkler.org/FS/FSMunicipalRports.html<br />FM Global – Environmental Impact of Automatic Fire Sprinklers<br />-Reduction in water usage by fire sprinkler system could be as much as 91% compared to manual suppression<br /> -Approximately 10 times increase - similar to this study <br />Available here: <br />http://www.fmglobal.com/page.aspx?id=04010300<br />Water Usage Results<br />
  7. 7. <ul><li>Calculations of the expected water discharged by fire sprinklers per home fire:</li></ul> - hydraulic calculations on fire sprinkler designs for typical one- and two-family homes<br /> - calculations assumed a one- or two-sprinkler operation of highest water flow and greatest system pressure demand<br />Study Tasks – Water Usage<br />
  8. 8. Calculations based on most probable scenario based on actual sprinkler design plans:<br /> - single sprinkler operation<br /> - average system discharge 28 gpm<br /> - exceeds required minimum flow of 18 gpm<br /> - system discharge up to 280 gallons per fire<br />Water Usage Results<br />
  9. 9. <ul><li>Estimation of the reduced water infrastructure demand when fire sprinklers are present in all homes within a community:</li></ul>- projected infrastructure demand is reduced at least 47%<br />Water Usage Results<br />
  10. 10. <ul><li>Evaluation of the performance of water meters when used to supply residential fire sprinkler systems
  11. 11. Series of experiments on commercial residential water meters under a range of flow conditions to investigate:</li></ul> - pressure loss profiles<br /> - metering accuracy<br /> - functional integrity<br />Meter Performance-Study Tasks <br />
  12. 12. Failure of water meter components<br /> - Observation of water meter<br /> - Failure based on reduction in flow rate and/or pressure<br /> - 20 minute test per flow condition<br />Water Meter Performance<br />
  13. 13. Water Meter Performance<br />
  14. 14. No water meters failed resulting in flow obstruction during any tests<br />Post test visual inspections indicated no signs of physical water damage to any meter<br />All tested residential water meters are capable of handling the minimum fire sprinkler flows required by NFPA 13D<br />All tested meters are capable of handling the expected 28 pgm for single sprinkler operation without failure and with metering accuracy<br />Meter Performance Results<br />
  15. 15. Incentives for the Use of Residential Fire Sprinkler Systems in U.S. Communities<br />Whystudy incentives?<br />Toidentifytheirvalue<br />Tounderstandtheimpact of thesevalues<br />Toincreasethe use of firesprinklers<br />
  16. 16. Incentives for the Use of Residential Fire Sprinkler Systems in U.S. Communities<br />Importantfactors:<br />Time specific<br />Single issue<br />Futureconsiderations<br />
  17. 17. Incentives for the Use of Residential Fire Sprinkler Systems in U.S. Communities<br />Researchobjectives:<br />Identify incentives/types<br />Characterize incentives<br />Estimatethevalue of incentives<br />
  18. 18. Incentives for the Use of Residential Fire Sprinkler Systems in U.S. Communities<br />Types of incentives:<br />Financialtrade-offs<br /> - Developer<br /> - Builders<br /> - Homeowners<br />On-sitedesignflexibility<br />Off-sitedesignflexibility<br />Indirectvalue<br />
  19. 19. Incentives for the Use of Residential Fire Sprinkler Systems in U.S. Communities<br />Estimatedvalue of incentives:<br />Homeowner-Oriented Incentives $145<br />Builder-Oriented Incentives $1,949<br />Developer-Oriented Incentives $1,271<br />Typical incentives to home builders offset 33% of system cost<br />
  20. 20. Incentives for the Use of Residential Fire Sprinkler Systems in U.S. Communities<br />Future research: <br />Identify the most influential types of incentives <br />Identify the most impactful stakeholder group to target with incentives. <br />
