Conclusion
There are over 166,000 thermal sensors covering a nominal 20
sq. ft. of skin on the human body...and we expect a single
thermostat connected to a furnace to satisfy them...
go ahead take a few minutes to think about.

We
condition people.
The Perfect Thermostat
Your Brain
"It came programmed at birth and
you don't have to touch it. It doesn't have any dials and
no fancy blinking lights. It works 24/7/365 and in all weather
conditions. It doesn't need spare parts and requires no external
source of power. It is perfect." Robert Bean
Message at the 2005 HRAI AGM
"....the perfect
heating and cooling system would be based principally on human
comfort factors." Michael
McDonough
Architect
"...the knowledge of the temperature contributes to our feelings of comfort and acceptability."

Human Physiology
4, The Mind - Body's
Sensory Systems
The
skin sensors are connected to the nerves which are connected to
the spinal cord which is connected to your hypothalamus located
in your brain. Your hypothalamus makes decisions on how to
control your thermal comfort. It came programmed at birth and
you don't have to touch it. It doesn't have any dials and
no fancy blinking lights. It works 24/7/365 and in all weather
conditions. It doesn't need spare parts and requires no external
source of power.
The Brain - YOUR BRAIN - is the real thermostat in your house
and it is perfect.
Map of the
"Tactile" Cortex.
The various parts of the body are drawn proportionally to the
number of neurons inside the relative projection areas.
What architectural
, interior and mechanical designers should note is how important
the feet, hands and head are to sensing the interior
environmental conditions. For example, "the fingers of the hand
send stimuli to an area of the cortex equal to that which
elaborates the stimuli of all the rest of the body."1
That's why radiant skin losses from the neck,
head, and hands plus conductive losses through the feet in
contact with cool floors contribute to discomfort more than any
other area of the body. It is the #1 reason why radiant based HVAC systems are the ideal natural solution to
improving ones indoor environmental quality. Blowing air
may be cheap and low cost but not and will never be a human based
solution to comfort conditioning.
Your Brain - Your Thermostat, Part I
We learned in
Human Physiology 3
that our skin has tens of thousands of sensors which feed
information to our brain. The part which is important to
thermal comfort is the hypothalamus.

The
interior environmental conditions are picked up by your skin
and fed into your brain through groups of sensory nerves
connected to the spinal cord which is connected to the
hypothalamus. Illustrated below are the nerve groups.
