[Bldg-sim] heat gain of children?

[Peter Simmonds]

Agreed, but the metabolic rate can be adjusted in proportion to the body
area. If you use the new ASHRAE 55 thermal comfort you can run all the
different metabolic scenarios and adjust these for different body areas.

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.
