Hello, this is my first post here...
I'm modeling a 49-story building (baseline design according to the Standard ASHRAE 90.1-2007). Well, the whole building is already done, so my question is regarding the simulation.
Well, Standard ASHRAE requires the building to be modeled with 4 different orientations (0º,90º,180º and 270º) and for each case I should resize the capacity of the cooling equipment (multiplying by 1.15 to the chillers capacity, it's simple because I only have 2 chillers in my model, and by 1.25 to all the heating equipment, so here is where my problem comes). Actually, I have heating coils for all the 49 floors (and even more than one per floor), so it would be really annoying and laborious to oversize each heating equipment.
In other words, what I normally do so far is to simulate once (it takes me about 6 hours because my model is kinda heavy), then resize all the cooling and heating equipments and simulate again (6 more hours) because this is the final result I need. Then, I have to set the orientation to 90º (it was 0º by default), simulate once and then resize and simulate again. And it's the same story with 180º and 270º. In conclusion, I would have to simulate 8 times, but I can't because I don't have much time.
So, to sum up, what I want to know is if it's possible to deal with these two parameters (orientation of the building and resizing factors for heating and cooling equipments) so that I just set them (0º,90º,180º,270º and 1.15, 1.25) in EnergyPlus and get the final result for each orientation. Also, is it possible to simulate the four final configurations simultaneously?
I would really appreciate if someone help me with this.
Thanks in advance!!
Billy.
