<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>I will take a step back here and try and
try and rephrase what I was trying to say earlier. I know temperature flows can
be modelled predicatively and also that ashrae has a standard for thermal
comfort that includes a lot of studies but also a lot of reservations
concerning subjectivity of human comfort (which is what we are talking about). If
we were just making an unoccupied room comfortable for its own sake (as if
rooms complain) then balancing heatloss by raising the temp a degree might
accomplish something<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>Now some of the interior walls or objects
might complain about the 1 degree rise if they were more comfortable at 70 but
they can argue with the window or some object near the window who might not
feel that 1 degree is sufficient.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>Now I am that object near the window sitting
on my panang (I just realized that bald people probably have a less active hypothalamus
and better brain function – but I’m not balding yet – just envious).
My panang (I now know what that is – thanks to google) has been sitting
by itself by the window all day so is a few degrees less than 70. I’m
looking forward to sitting here as I have a new exciting ASHRAE standard that I
am pretty keen to read through so am not about to get up. In complying with the
John Straub ‘naked man specification – NMS-1) there is little
between me and the window (though my rear is covered by a slightly cooled
panang). <o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>Now I had raised the thermostat 1 degree
to compensate for my comfort as an NMS-1 and as per ASHRAE - at my favourite
place by the window view (good light too). I can’t say I was entirely
comfortable and noticed that my skin was showing signs of piloerection (goosebumps)
while other parts were not and were actually retracting and my overall body was
shivering slightly. <o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>Now despite the fact that my body is
producing heat (3-400 btu/hr or so) I realized that my body was feeling the
difference and starting to compensate dramatically and that that wouldn’t
be the ideal ‘comfort’ condition for reading ASHRAE. So not wanting
to move - I asked my partner to turn the heat up. <o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>Now away from the window (having turned up
the heat) most inanimate objects are within a degree or two of 70. Now my
partner is going through hormonal changes that can push body temperature up as
much as 6degC and she is not currently in compliance with NMS-1 or even NFS-1
so feeling the affects of both ASHRAE comfort standards and some subjective
overheating refuses to comply with my request and actually requires me to
change my status to a Clothed Male – CMS-1 (preferably with sweater).<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:

panang next to the nearest radiant heater.<o:p></o:p></span></font></p>
