Hello all,

 I am currently working on a office building where I am looking at the energy use difference between employing a morning warm up of an hour and no morning warm up. When I drop the morning warm up, my heating energy use drops by over 12%. This seems relatively high and I wanted to know if this is typical or if there is something I am not taking into account. My method for dropping the warm up was to push back my the OA schedule, fan schedule and heat schedule back one hour to the time of building occupancy. Am I modeling this correctly or is there extra steps that need to be taken? I'd attach the .inp and.pd2 files but I am unsure how to attach files to this forum question. Any help is appreciated.

Thank You,
