Can someone point me to some literature or explain cfm50 to me. I've recently had a energy audit on my home because it is freezing in my master bedroom, and I wanted to see if they could find any air leakage that may be casuing this, and the report bascially told me there is nothing to be done, because my house was too tight.
The results of the blower door test is that my house is at 3210 cfm50 and that if I go any lower that I would be violating some sort of air quality standard. They said the opitimal levels are 4131 cfm50, I've tried to do some research but I can't really find anything about a standard, and what I have found is that, the tighter the better, and that you would need to dip below 1000 cfm50 before you would require putting in a mechanical ventelation system.
One l link that I reviewed from this site: http://www.pct.edu/wtc/docs/articles...Door-FINAL.pdf states that 1,500 is tight, between 1,500 and 4,000 is moderate.
This company seems a bit shady, and I feel that the informatoin that they have provided is not accurage or skewed. Could anyone shed some light on to this I would appreciate the help.
