Hi All,

I am currently modeling a building in DOE2.1e and am trying to comply with ASHRAE 90.1-2007 section G3.1.3.4 which states that:

Hot-water supply temperature shall be reset based on outdoor dry-bulb temperature using the following schedule: 180?F at 20?F and below, 150?F at 50?F and above, and ramped linearly between 180?F and 150?F at temperatures between 20?F and 50?F.

DOE2.2 allows you to model this in the "CIRCULATION-LOOP" command, but DOE2.1e does not recognize that code-word. Does anyone know how to incorporate hot-water temperature reset in DOE2.1e?

Thanks,

Eric Zagorski
