    10th IAFSS Fire Escape Modeling Workshop 10th IAFSS Fire Escape Modeling Workshop Presentation Transcript

    • Workshop @ 10th IAFSS Symposium 2011 – University of MarylandMODELS: Fire and escape modelling- from bits and bytes to safe buildingsChairs: Peter Thompson and Jason Floyd
    • Chairs / Participants• Chairs: – Jason Floyd, Hughes Associates – Peter Thompson, Integrated Environmental Solutions• Panel: – Guillermo Rein, University of Edinburgh – Randy McDermott, NIST – Ed Galea, University of Greenwich – Jamie Lord, ATF – David Stroup, US NRC Workshop @ 10th IAFSS Symposium 2011 – University of Maryland
    • Workshop aimsSummarize the current process:• Data collection• Creating the models• Applying the models• Regulating the use of the models in designDiscuss the issues & look forwards• Where is it good ?• Where are the shortfalls ?• Comparison with other industries…• Planning for the future: ensure life safety… Workshop @ 10th IAFSS Symposium 2011 – University of Maryland
    • Workshop format• Block 1: “Experiments and Models” (45mins) – Guillermo (experimentation & data gathering) – Randy (fire model development) – Ed (escape model development)• Block 2: Use, review & regulations (30 mins) – Jamie (application of fire and escape models) – David (regulator / AHJ) 5 mins. break• Block 3: Discussion (60 mins) – Chairs‟ summary (10 mins) – Panel discussion, followed by open-floor discussion Workshop @ 10th IAFSS Symposium 2011 – University of Maryland
    • Block 1: Guillermo - experimentation & data • PPT presentation (click here) Workshop @ 10th IAFSS Symposium 2011 – University of Maryland
    • Block 1: Randy – Fire model development• PDF presentation (click here) Workshop @ 10th IAFSS Symposium 2011 – University of Maryland
    • Block 1: Ed – Escape model development• Data, Development, Testing• Presentation (click here) Workshop @ 10th IAFSS Symposium 2011 – University of Maryland
    • Block 2: Jamie – Applying the models• Issues with Fire & Escape models – Usability, Validation, Time, Results• PPT presentation – click here Workshop @ 10th IAFSS Symposium 2011 – University of Maryland
    • Block 2: David – regulator / AHJ• Models, issues, assessments + legislation• PPT presentation click here Workshop @ 10th IAFSS Symposium 2011 – University of Maryland
    • Block 3… 5 mins. comfort breakBlock 3 – Summary & discussion• Fire model issues summary (Jason, 5 mins)• Escape model issues summary (Pete, 5 mins)• Panel discussion (10 mins)• Open floor discussion (40 mins) Workshop @ 10th IAFSS Symposium 2011 – University of Maryland
    • Block 3: Jason – summary, fire modelsDevelopment Issues • Bloat / feature creep • User feedback • Validation data • Experimental planning / reporting • Evolving Hardware / OS / programming languageTechnical issues • Material properties / standard test methods • Library of tests and results • Suppression & interaction of water with fire • Interactions w/ structure and occupants Workshop @ 10th IAFSS Symposium 2011 – University of Maryland
    • Block 3: Jason – summary, fire models Usability issues • Time (set up, analysis, reporting) • Clear, adequate documentation • User training • Reviewer capability • Standard scenarios / performance criteria Workshop @ 10th IAFSS Symposium 2011 – University of Maryland
    • Block 3: Jason – summary, fire models Standard Practice (US) – Wild West? • Model does not need accreditation • Little guidance on scenario selection and performance metrics • No formal QA procedure (individual projects or companies may have) • User does not need accreditation (PE license leaves decision up to the license holder) • AHJ does not need formal training / no requirement to external reviewer Workshop @ 10th IAFSS Symposium 2011 – University of Maryland
    • Block 3: Jason – summary, fire models Contrast with US DOE NQA-1 • Model must be accredited for the specific use • Software quality assurance • Version control • Detailed V&V applicable for the specific use • Specific quality assurance requirements for reporting • Peer review requirements Workshop @ 10th IAFSS Symposium 2011 – University of Maryland
    • Block 3: Pete – summary, escape modelsTechnical issues:• Lack of test results in the right format• Level of detail for model parameters• Standard test methods for software (IMO ?)• Library of tests and results ?• Define what you are attempting to model !Usability issues• Time to set up the model• Speed of analysis (parallel processing, etc)• Presenting results (3D, movies etc.) Workshop @ 10th IAFSS Symposium 2011 – University of Maryland
    • Block 3: Pete – summary, escape modelsCompare with Energy Modeling industryUK: tightly regulated (European directive)• Software must be government approved • (standard test cases, clearly defined calcs.)• Users: must be approved Energy Assessors • Govt. approved training schemes• Projects: approved users create EPC certificates• Project storage: online „Lodgement‟ Schemes• Quality Control audits of “lodged” projects Workshop @ 10th IAFSS Symposium 2011 – University of Maryland
    • Block 3: Pete – summary, escape modelsCompare with Energy Modeling industryUSA (LEED & US Green Building Council):• Software voluntary approval: EPAct • (ASHRAE 140 test cases, check principles.)• Users: LEED Approved Professionals• Projects: Every project is checked at the point of submission (by USGBC) so every project is reviewed and audited. Software is reviewed at the discretion of the reviewer.• Project storage not publicly accessible Workshop @ 10th IAFSS Symposium 2011 – University of Maryland
    • Block 3: DiscussionPanel discussion (10 mins)• Data gathering, model development, application and regulation…• Connections, disconnections, requirements…• Planning for better, applied modelingOpen floor discussion (40 mins)• Thoughts from the floor• Panel responses“The way forward” - actions Workshop @ 10th IAFSS Symposium 2011 – University of Maryland
