Some of the information had to be juggled a bit, I still think this is a bit off. Energy-10 makes some big assumptions that I’m not sure are correct but are impossible to tell (i.e. that a certain amount of people will change the energy required, but it has set points for amount of people that go through the building). The window count may be off but its set to about 90 % of each façade. Notice that units are in kBtu / square foot.

PUMP SIZING:

I haven’t found a guide yet that will give me a good pump selection (that I don’t have to pay for) but I have all the inputs.

The best selection for parts of this system will occur when the flow is most turbulent. Turbulent flow is based on the Reynold’s number, dictated by material properties, lengths, and geometry.
Based on some standard fluid mechanics equations (not shown for clarity, but will be included later) any size pipe will do to get turbulent flow, based on the flowrate required and the geometry of the pipe layout. According to this excel Macro, and using a height of about 35 feet (TBD) and a pipe diameter of ½ inch, the pressure drop is determined. Note that this information was just determined with a macro, but for the final report the equations will be shown and run through individually.

As for the heat exchanger used, I have to talk to the engineers already on the Keating boiler project. They recommended the same exchangers that they currently use, which should be about $4000.
