[Bldg-sim] thermal energy net simulation, which simulation tool shall i use

[Grando, John]

Jeorg,

I would guess that your most likely solution would be the following:

1. find out how many buildings are similiar enough so that you can reduce your number of modeled buildings and just use multipliers.
2. model those representative buildings.
3. output their hot water use from the district plant.
4. sum their hourly profiles up (remember to apply multipliers) using excel or some other spreadsheet calculation method.
5. Make your Cogeneration plant in the last model and attach an hourly process load to the hot water loop that is representative of the summed up hourly load profiles.

This may be a little time intensive/computing power intensive to simulate and sum up all these results so try to use multipliers as much as you can with similiar buildings.  Good luck!

Joerg:

If you don't mind a non-Metric answer, eQuest should fill your needs nicely. It has reciprocating and gas turbine capabilities, with both jacket and exhaust heat available in the engine case. The only thing I am unsure of is taking the exhaust gas from one prime mover and injecting it into another.

It also has quite substantial central plant capabilities as well.

Dear all,
I want to combine several dynamic thermal building simulations (10 different residential building types and, overall 200 buildings ) with a zentral energy net plant (eg. co-generation / tri-generation) simulation. Can anybody tell me a Simulation tool to do this?
