Well done to the Marlborough Express again for coverage of the frost fan hearing.
Cumulative effects (again (surely the cumulative effect of all these people saying something about cumulative effect will have an effect?)).
Serious health issues (sleep deprivation could include cardiovascular disease, mental-health effects and impaired cognitive performance).But the most interesting thing of the day appears to have come from a lawyer and his client and it's kind of a big deal.
The argument goes a bit like this;
If you have an existing fan that was installed under the old rules where effectively you just had to get a building consent and bung it on the ground, then if it was shown that your fan did not meet the standards in the district plan (that would be the old standard I presume), you wouldn't have any existing use rights (because you never had a resource consent to operate beyond the limit in the Plan. At that point you would be forced to apply for a resource consent for your fan and it would appear that you would need to meet the new standards.
Opps!
Let's see if I can paint an ugly picture here.
What if installers have been putting in fans for years and just bunging them on the ground and not bothering to set the speed of their fans to match the manufacturers recommendations for the required noise level?
Actually, this might have been happening already.
Young Malcolm Maclean has been measuring fan speed and his measurements seem to indicate that Orchard Rite and Amarillo frost fans are being run at speeds that would make them non compliant according to the manufacturers data.
The Frost Boss 4 bladed models look pretty good, but if the worst case scenario is true, those with Amarillo or Orchard rite fans should be getting their installers to set the fans to a compliant speed.
I'm picking they probably don't know what the compliant speed is.
If you have doubt, Malcolm included a look up table in his measurement document that provides a reference to the manufacturers data here.
Malcolm, you may want to make some comment?

Gidday Jack.
The hearings were very interesting. I was a trifle disappointed that there was no one from the wine industry that was in attendance for the entire three days, but I suppose it was in the middle of vintage.
With respect to the speed measurements, I was asked about it by the panel and replied that the measurement I had taken indicate widespread non-compliance.
The figures that I think I published on the blog last year don't actually tell the full story, since then I analysed a further 19 fans.
So the total measured was 42.
Of the random fans only one Amarillo was compliant and no Orchard Rites were compliant.
There was one Frost Boss that I measured as non-compliant.
This has cemented what I had observed from the initial measurements. Amarillos and Orchard Rites are generally run at speeds that make them non compliant. Frost Boss's are generally run at compliant speeds.
Thanks Malcolm. If you have any of the submission papers you can forward that would be great.
Not many surprises with the fan measurements. You should volunteer to do measurements for fan owners who are concerned that their fans are running too fast :-)
