[Bldg-sim] heat gain of children?

[Robert Gengelbach]

It seems to me that correlating a child's body area  with heat loss as a
direct ratio of an adults heat loss would not account for the significantly
higher metabolic rate that children have.  Remember there are various heat
loss values published for adults depending on their activity level.

Cramer, from my old days of studying thermal comfort I seem to remember a
correlation between heat output and body area. I seem to remember that
average adults have a body area of 1.68m2 that produce 70W of sensible heat.
So if the body area of a child is less than the 1.68m2 then the heat output
can be reduced proportionally. I think this is report in Thermal Comfort by
Fanger, 1972

Hi All,

Has anyone out there every come across data for the heat gain of children
(for cooling load calcs)? I searched the ASHRAE handbooks but didnt find
anything, just the usual numbers for adults in the thermal comfort chapter.
My current thought is to use the adult numbers adjusted by mass, but if
there's real data that'd be great. Any hints would be appreciated.

-Cramer
