Maybe the difference of site energy is small because in all the orientations, similar energy is required to bring the building to the selected conditions. It does seem weird though and the model should tell more to the experts here that will take a look at it. |

| 2016-01-05 22:20:49 -0500 | asked a question | E+ and CFD - RoomAir:TemperaturePattern:UserDefined Hello, Upon reading the EnergyPlus IO reference I came across this object. From its description I gather that this a sort of post-processing object, using results the user might have (most obvious source stated is CFD). Unfortunately, my level on E+ scripts is begginer at best and the description provided in the reference isn't really illuminating. From what I gather, the CFD results could be inputed in the form of a temperature stratification using a lookup table (perhaps with nonDimensionalHeight object?). But I really can't be sure. I wonder if anyone here has had any experience using these objects to connect outside data (e.g. CFD results) with E+. Thanks in advance. Kind regards, Theodore. |

| 2015-02-24 19:50:09 -0500 | commented question | daylighting and energy plus Hey Rpg777, Sorry I thought I'd be laconic my first time here. Workflow is this: First, I am using Honeybee, with the help of daysim and radiance, to do rough daylight calculations for a zone (open office type), although it can be any type or number of zones. Second, I analyze the results and I select only the fraction of the floor area that is above 3.5% Daylight Factor. That is my daylight zone. Third, I refine the daylight calculations in the daylight zone. I then use those results to create a lighting profile through Daysim. I then input this profile as a lighting schedule for my zone. |
