We did this calculation a while back ...
If you're using all solid state lasers, I'm guessing that lasers will be a much
smaller contribution, so it's likely to be computers (200-700W each) > people
(~100W each) > arc lamp (~150W) > lasers (10-100W each if solid state) > all
other controllers (5-30 W each). Not sure about your incubator - gut feeling
tells me it's likely to be around 100 - 200W. As far as heat output goes - it
should be be the same as electrical power consumed (although not necessarily the
plate numbers - because, as mentioned, they are the maximum possible current
draw).
Don't underestimate people when calculating thermal load - you can count on ~
100W heating per person. The other item which is easy to forget is lighting -
which easily contributes a couple of hundred watts. When specing the aircon you
might want to consider the possibility of wanting to use, e.g. a small gas
laser, in the future - these easily draw 1-2 KW and are still the best option
for some lines.
Also don't be afraid to overspec the number of outlets - I'd suggest ~ 2x what
you think you're going to need - we've ended up with using around ~20 for our
TIRF rig.
It's still hard to arrive at a firm figure for total consumption - but ~ 2 KW
plus the power of any gas lasers you might want to use is probably in the right
ballpark.
Cheers,
David

Hi Christophe!
By using the power consumption on the plates, you are actually making a
conservative estimate of the heat that may be generated by the equipment, as
this is the maximum power that the device will draw. The lasers and controllers
are generally the biggest power consumption items. Our TIRF laser for example is
120V/1100W. Since you are using the plate info for each piece of equipment, you
should be fine. Make sure that you include all of the computers/components as
well. The only source of heat that you don't account for by using the plates is
people in the room, which the overestimation inherent in the plate numbers
should easily cover.
I would suggest adding at least one additional outlet/electrical drop in the
room for any additional equipment or computers that you might need in the
future.
Hope this helps!

Hi,
I have to supply the total electrical consumption of a fairly standard TIRF
setup (with a whole-box incubator and solid-state lasers) for preparing a
new microscope room (electrical outlets and air conditioning). I have looked
at the electrical consumption written on plates behind various components
but I'd be glad if someone could give me a rough estimate of how many watts
that kind of setup needs. What are the elements that usually consume the
most power ? What are those who generate the most heat ?
Thanks for your help,
Christophe Leterrier
