[BLDG-SIM] LEED and evap chillers

[Mitchell Dec]

Wade,

I had a similar question submitted to the USGBC and it was deemed a water-cooled system. However, if the capacity is less than 150 tons, there was a CIR allowing the use of an air-cooled systems.

This may have been covered in a previous thread, but I'm away from my email archive at the moment.

Regarding LEED modeling with respect to the ASHRAE ECB/DEC method: Does anyone have a sense of whether an evaporatively-cooled chiller is considered air- or water-cooled?   It makes a considerable difference to the modeling of the ECB (base case), and thus to the evaluated savings.

Thanks,
