A 0 hers rating is a net zero home, 100 is national building code, under 85 is energy star... its about energy consumption.... Im not the scientist of my company I only play one on blobs..... if you want email leia@brightalt.com to talk real good bs... (building science) |

oh,,i thought it was bambu floors,, energy consumption???hmm,,geothermal,,,???the consumption is the same if the house is insulated to crap,,but the cost to the user is less to waste the energy out the walls and thru the roof,,,green indeed,,dont matter if the house is heated with a bucket of burnin horse crap,,the load is the same,,,but they got a lower hers number for it much like the trade down for the fancy fridge that saves em,,,look at the sticker,,25 smackers a year,,green indeed,,,(and lets not forget our bambu floor,,embodied energy only matters with spf)oh baby were makein a difference here,,now honey go pay that 400$ utility bill and crank up the ac its hot in here,,,, so,,shudda we drilled some holes in da wall to make that blower fan thingy work??? shudda we just pulled the numbers outta our rectum like some of the fellas out there(seems if you look at there hers rateings all there homes have exactly the same numbers,,hmm,,,and my frameing and drywall freinds have never seen one of them blower door thangys near one of their homes,,hmm,,,great system we gots here,,, insulators rating there own homes,,,or a sub entity rating there own homes,,,and relationships are developed because of these "services" that can be provided,,,no doubt,,pretty houses with real nice 5 star plus rateing that work like the homes they built 10 years ago,,,cause guess what,,,they are being built like they were ten years ago,,, |

Foamdude... I am relatively new to the board, but have been a regular reader for some time. I have nothing close to the amount of experience in foaming that you have, so you'll have to pardon my naivete and not take it as an affront to your professionalism. I do, however, have a background as a BPI certified professional. I just did a blower door test on a home (a code compliance test to meet 2009 IECC air leakage requirements) Friday afternoon, and had the same initial problem. I advise my customers to have the test performed no later than the completion of the drywall phase just in case, as you mentioned, there is a problem that needs addressing. House had a veneer plaster finish, which created an excellent air barrier, so I knew the number would come in low... I run a Retrotec blower door system, and had the fan on at 100% speed and the read out said "too low". As the Retrotec DM-2 controller reads the same when it cannot reach -50 due to too much or too little air flow, it took me several minutes to figure out I had made the simple mistake of not installing the air flow reduction rings. I don't know your exact situation, or whether you tried several ways, but thought I'd at least bring it up... |
