Some time ago somebody asked "who needs Btu?"
One answer is ASHRAE for it's publication High Performance Buildings.
I asked them to use SI. They said no. Their readers are builders
and maintenance people who want to see inch-pound units.
The units used are:
ft
in
square footage
R value
kBtu
kBtu/ft^2
heating degree days
degree F
therm
gallon
kWh
gallon
W/ft^2
MMBtu
cfm
cfm/ft^2
acre
lb
kcf
lb
mile
mpg
ton (cooling)
In the winter 2011 issue for the two plants in Ohio Honda lists
GJ first with kBtu in paren as 5.13 GJ (4.872 kBtu).
ASHRAE Journal allows some SI.
