"Hey Kent, unfortunately we do have RESNET CAZ training available in Washington or Oregon. However, if you're looking to meet this requirement before the end of the year, we do have several RESNET CAZ training courses around the country still…"

"Hi Barbara, You are right about being able to model details accurately.  But then we are challenged with how to model actual useage as well.  For your question here's REM's suggested solution: At this point we suggest the…"

Ed Minch replied to Kent Mitchell's discussion Fire sprinklers & air infiltration?
"This is not the only problem with sprinklers.  Any pipe in the attic with water in it must be protected from freezing, and the standard practice in the mid-Atlantic has come to be called "tenting".  The insulator will cover the…"

JEFFREY M HUGO, CBO replied to Kent Mitchell's discussion Fire sprinklers & air infiltration?
"I understand now. You are speaking of the annular space between the cup (housing) and the sheetrock. In the perfect world, there is tight fit but we both know how that works 99.9% of the time. Can this area be filled with caulk or compound? I would…"

Kent Mitchell replied to Kent Mitchell's discussion Fire sprinklers & air infiltration?
"We understand that, and it makes perfect sense. That is not the issue.   We are not talking about sealing the cover plate.  It's the housing where it meets the sheetrock - not the escutcheon or the cover plate.  On a…"

JEFFREY M HUGO, CBO replied to Kent Mitchell's discussion Fire sprinklers & air infiltration?
"Kent, Sealing around the bottom edge of the edge of the cover plate violates the (UL & FM) listing of the product, and it specifically violates NFPA 13, NFPA 13R, NFPA 13D, NFPA 25 and the soon to be out 2015 IECC. The sprinkler standards (NFPA)…"

Bud Poll replied to Kent Mitchell's discussion Fire sprinklers & air infiltration?
"So actually the temperature difference they need to move the air, call it convection or stack, is from the fire.  That makes sense and would easily override the lesser temperature differences of house stack effect. I have had some dealings with…"

Bud Poll replied to Kent Mitchell's discussion Fire sprinklers & air infiltration?
"Hi Kent, educate me? Since air doesn't always move up through the ceiling plane, stack can be zero or reverse, what is the sprinkler relying on to trigger a response? Bud"

Acronym CRAZY...

I don’t believe this is an industry specific issue but we do seem to have an excess of acronyms. 

For example we have RESNET, HERS, BPI, LEED, CSG, ACCI, ANSI, OSHA, WISHA, OMG, & LMAO! 

Confused yet?  No – then let’s try these on for size… ACH50, ACHNAT, SIPS, DMHP, HP, WH, HVAC, CFM, ELA, SLA and IECC, MEC, ASHRAE but don’t forget NYC! 

BTW can you name EPA, HERC, OSB, PVC, ABS, BD, DB, MDF, MDO, SEER, HSPF, HRV’s, ERV’s, DOE, NGBS, BIA, PV, UV, UVA, UVL, DHW, IAQ,…
