  1. Nick likes to look at one axis of a chart and pretend it
    supports his argument.

    He utterly ignores the other axis, such as temperature, and
    ignores the fact that where they meet in the middle is RH.

    At 90 F / 35 % RH, most people would describe the weather as
    'hot but dry, not bad at all, a nice summer day'.

    At 70 F / 70 % RH, most people would describe it as 'clammy,
    oppressive, and uncomfortable'. You would also have a dew point of ~
    60 F, only 10 degrees below DB, conditions very favorable to
    condensation and mold.

    And yet, in both cases, the ABSOLUTE HUMIDITY is ~ 75 grains.

    Thusly, Nick is full of shit, as always.

    Apparently just another one of Nicks fan club... Typical.. ;-p

    The ASHRAE 55 comfort zone is defined with absolute humidity limits.

    And to think ...Just a while back Nick thought Humidity was witchcraft..
    Will wonders never cease!

    Fresh air in L.A.? You gotta be kidding.. And San Diego Night air can
    get really sticky in the Summer and penetrating in the winter...And
    always a high humidity count. If you must deal with coastal air.. Dump
    Nicks ass and check with the US Navy Weather stations. Every ship takes
    hourly Sling readings at sea and in port. Seattle isn't any better.
    And just what do you call feircely cold?? I do suggest that for
    competent figures on the comfortable content level of air...
    Go to the Pro's over at ACCA. And do select someone whose profession
    covers this.. Not some hobbyist! Get some good pyschrometric charts.
    and the humidity, usually from
     
  5. ....
    When it is 90 at night, it was 110 at 2:00 and the house is over 100. 90 is
    nice and cool then. Of course we never had central air, so the option of
    open or closed was mostly open or die.

    Don. This is a mean spirited and insulting comment. Also typical of a class
    of such polemics that I do not care for, so my reaction is much stronger
    than is warranted by the comment itself. Nick's comments may not always be
    worth their weight in gold, but at least he bothers to provide comments of
    some substance (and of course error). Consider what you just did in regards
    to your complaints. Rather than providing personal experience, contravening
    data, analysis, etc., you attributed to me a position I do not hold (ask
    Nick if you want. I rather imagine his comment on that would not place me in
    any fan club he would belong to), then dismiss my comment as "typical". If
    Nick had provided such a comment you would rightly accuse him of using such
    lame polemics because he didn't have any substance to back up his position.
    So I would suggest to you that you evaluate your own comments just the way
    you would have Nick's or mine, and then attack your own error. Come back to
    us with a comment crafted to be at least generally consistent with the lofty
    goals of reason you seem to want to set on others.

    BTB. Nick. What will we call your new fan club, now that it has one publicly
    identified member at least?
     
  7. I remember once working in a telco cable vault ( buried
    rom-sized concrete equipment box - they're all over the place ) where
    the AC had quit ( which was why I was there ). After an hour or so in
    there with all that equipment running and no AC, I climbed out and
    thought to myself 'wow, what a relief to be back outside where it's so
    nice and cool !' . Then I remembered that it was 98 F and humid
    outside. But that was comfortable and enjoyable compared to inside
    the vault :)

    Smog is interesting stuff. Sort of a big bowl of stagnant air that rocks
    back and forth with the desert heat cycle. In the afternoon the sea breeze
    pushes it inland and up into the desert, and in the morning it reforms
    around the sunny vallys. There are a few areas where it is really nasty at
    times (by nasty I mean green enough to be quite discernable, with a decided
    odor, and a bite.) In most of the coastal areas the night air is a lot
    cooler and cleaner. If I had to live there, I would have to filter and cool
    the air just to be able to breath it. Asthma you know. But the night air
    generally drops 30-40 F from the daytime, the humidity rises to dew on the
    grass, but rarely to fog, and the outside air smells better, smog included,
    than the inside. Again, I am speaking of personal experience which excludes
    air conditioning and does date back a long time. I have noticed that the
    rapid drop in temperature as the afternoon progresses can make some of the
    most lovely warm and comfortable conditions for a pleasent back yard party,
    or just a walk in the garden.
    Personally, I keep my house around 55 at night, and it is OK down to about
    50. When the outside air is in the 20s we generally button up. Sometimes in
    the 30s, depending on our schedule and how active our evening has been.
    Fiercely cold is approximately equal to less than 30F.
     
  9. At 50 degrees, getting up to pee or not in the middle of the
    night becomes a real judgement call .....

    In Guelph Ontario they got the clothes line ban banned.

    I grew up in Elmira with no A/c - back in the days of the Gordon Young
    rendering plant and Naugatuck Chemicals (later Uninroyal, now
    Crompton)
    If you had the windows open you'd gag on the lowsy air.
    A lot better now.

    I now live in Waterloo, and AC is used several weeks every summer. We
    get the nineties F and high humidity, with poor air quality (some of
    the worst in Canada) for at least a few weeks each year. I would not
    be without air any more.

  14. That's great to hear. Clearly there is hope yet!
     
  15. I don't want to do without air either, but I can manage without AC. :)

    There certainly are people who need AC for health reasons. However, for
    most of us it's just a matter of comfort. I don't really understand why we
    should *need* AC when all of humanity has done without it up until a few
    decades ago.
     
  16. We also did well and survived for more than a million years without in
    door toilets. I do understand.

  17. I concede that you have an excellent point.

    However, how does the value of the comfort compare to the cost of providing
    it? Centralized water supply and sewage treatment systems are probably
    better for the Earth at large, and certainly provide obvious health benefits
    for all us people.

    AC, on the other hand, does nothing positive for the world at large, while
    expending a very substantial amount of electrical energy (which must be
    about the highest grade of energy we use). I suspect that fewer people will
    think the comfort worth the cost when electricity prices begin to reflect
    the real cost of the energy more closely.

    I am biased, though. I'm really a very bad Canadian, preferring sweating
    over shivering. :)

    Donate the top loader to charity. you'll cut your water and electric usage
    of the washer by two thirds. We love our Kenmore 44072

    I'm 1.5 hours south east of Ottawa. We don't have/need air conditioning.
    We love our Kenmore frontloader and gas dryer.
