Pat Dundon replied to Eric Timon's discussion BPI to Adopt ASHRAE Standard 62.2010?"thanks again. get it in the standard to 'decomission' fans that cannot be corrected if you can please. inspectors tend to look at the world as black & white and refuse to consider greys.
also please get BPI to…"
Paul Raymer replied to Eric Timon's discussion BPI to Adopt ASHRAE Standard 62.2010?"Hang in there, Pat. Geez. So much frustration! If there is an existing fan venting into the structure of a cathedral ceiling or into the ceiling or into the attic, you know it is doing damage! I worked on a house in NJ where…"
Pat Dundon replied to Eric Timon's discussion BPI to Adopt ASHRAE Standard 62.2010?"most fans are rated without ducting attached. a duct and a couple elbows will rapidly reduce a 100 cfm fan to 50 cfm. at full speed. that is why i said 100+ cfm fan."
Pat Dundon replied to Eric Timon's discussion BPI to Adopt ASHRAE Standard 62.2010?"Thank you for this Paul. I was on a webinar yesterday where either I heard the methodology for existing fans wrong, or it was presented wrong.
Am I to understand from this that if an existing fan does not vent to outside, you must…"
Paul Raymer replied to Eric Timon's discussion BPI to Adopt ASHRAE Standard 62.2010?"There is a great deal of furor about the ASHRAE 62.2-2010 Standard a lot of which comes from only looking at parts of the Standard. Like a house, the Standard is a system and should be taken as a whole. Having said that, I want to look at a…"
Brennan Less replied to Eric Timon's discussion BPI to Adopt ASHRAE Standard 62.2010?"Pat, you will almost never need a 100 cfm continuous fan to meet 62.2, unless the home is very large (>3,500 ft2). Whole house mechanical ventilation rates are on the order of 0.17 ACH, which is usually in the 35-60 cfm range. Much…"
Pat Dundon replied to Eric Timon's discussion BPI to Adopt ASHRAE Standard 62.2010?"There are three markets here. New construction, where everything is planned and budgeted before anything is done, Wx, where the budget question does not involve the client and profit is not necessary,and retrofit, where the client's budget…"
David Meiland replied to Eric Timon's discussion BPI to Adopt ASHRAE Standard 62.2010?"There's a fairly cheap "Exhaust Fan Flow Meter" from Energy Conservatory that's worth owning, and if you don't want to buy theirs I've seen instructions for a home-made version. I have the TEC product, use it, and like…"
Sean Lintow Sr replied to Eric Timon's discussion BPI to Adopt ASHRAE Standard 62.2010?"Sorry I have got to say it - you (generically stated) all are great at parroting the mantra "THE HOUSE IS A SYSTEM" & then you promptly forget all about it when you do your SIRS & payback equations. Christ I saw…"
Pat Dundon replied to Eric Timon's discussion BPI to Adopt ASHRAE Standard 62.2010?"I am in NY. We have a retrofit program active now for those folks too high income for weatherization, but not rich. It is crippled by the Public Service Commission because the law said the work has to meet a payback based on the 'savings on the…"
Sean Lintow Sr replied to Eric Timon's discussion BPI to Adopt ASHRAE Standard 62.2010?"Sure 89 is toast & 62.2's formula is (Total square foot of a home/100) + (Number of bedrooms + 1) x 7.5 cfm)Now if you want to delve into a ton of the arguments about it - Carl Seville posted an interesting email thread about it as it…"

Eric Timon replied to Tim Marlett's discussion Building Airflow Standards and the Average Contractor"This is something I have been battling for awhile now. For me it is hard to explain the building airflow standard to clients without them becoming concerned about too tight of a home. It is important to explain that the standard is not necessarily…"
