I recently joined IBPSA USA with the intent of helping an innovative building systems manufacturing client find an Energy Modeling firm that will simulate the performance of his Composite Structural Insulated Panel building system. My client is a Texas based manufacturer of a very unique, composite skinned – fiberglass reinforced thermoset – structural panel and sheathing systems with a polyurethane foam core – R-26 in 4-1/2” thick panel. The composite skin acts as the structural member as well as the air barrier, vapor retarder and drainage plane – no house wrap is needed. The panels and sheathing have undergone extensive testing with Radco in California in order to achieve an ICC-ES report. Currently, there are not any prototype houses or buildings to conduct actual energy performance tests – blower door tests for example – only the ASTM and ICC-ES testing at this stage.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>The Composite SIPS – C-SIPS are attached to each other using an Fiberglass Reinforced Thermoset “H-Stud” – screwed through the panel’s skin – then the joint is sealed with a marine adhesive and a 3M Flashing Tape. Connections are made at the top and bottom plates with an FRT plate rather than a 2 x 4. The FRT joint connection materials are manufactured by Bedford Thermoplastics and have tested, measured performance with ASTM reports, etc. All adhesive and sealants or flashing tapes are manufactured by 3M or Venture Tape and also have the appropriate and required ASTM reports or ICC-ES reports.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>My fundamental question is this: is there a method or approach to simulate the energy performance of a complete home including these “wall assemblies” with composite skins, joint and top and bottom plate FRT materials? Or for a typical home as compared with 2x4 walls or other conventional wall assemblies? My client has reached out to numerous energy modeling firms and no one seems to have the ability or interest in modeling anything other than an existing wood / steel / fiberglass or foam wall assemblies where an existing number is plugged into the simulation model and it calculates the results (I know it’s not that simple). <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>If your firm has a methodology or process for modeling complex material systems will you please email me and let me know your thoughts and capabilities? I’ll share my client’s web site and contact information so you can begin a dialog on process, outcomes and costs.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thanks for your help and consideration.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Best, Brian<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Brian Strombotne<o:p></o:p></p><p class=MsoNormal>BPS Media<o:p></o:p></p><p class=MsoNormal>919-796-9983<o:p></o:p></p></div></body></html>
