Building Performance Analysis - Project Info

For those of your following along thus far with my overview of the upcoming release, we've covered the major changes to Volumes in Revit MEP, and discussed the new recommended workflows.  I hope all that is clear.

These volumes, in combination with the metadata associated with the volumes and project, constitute the input data required for our Heating and Cooling Load calculations.  Today we're going to take the next logical step, and discuss the metadata that's used as "fuel" for our Building Performance Analysis (BPA) capabilities.

Although I have been focused on "new things" for the past couple of weeks, this discussion is focused on all of the "fuel" that's used for our calcs.  In my cutting of the video, it seemed that this didn't hurt the process.  I hope this all makes sense to you all.

Building Performance Analysis Data - Project Info

Now you all can say "I know the data that's captured at a project-level for BPA calculations."  Tomorrow, I hope you can all say "I know the data that's captured on HVAC Zones and Spaces for BPA calculations."

Hi Kyle, Not being in the US we only get a few locations. If you override this with site specific coordinates how does it impact IES? Does it calculate based on the nearest "list location" (climate etc)?

For example I can choose Auckland or Wellington but what if the actual location is halfway between them?

Hi Kyle, I am in Australia and I know that I can set Location for places in Australia and other places outside of North America but I was wondering if I can set the Postal Code setting and if not will this create a conflict with my gbXML output being read by other programs?

Robin,
The IES VE consumes the coordinates defined in the Project Information of your Revit Project.

It checks that against the weather points available in our database, and chooses the location that's closest.

If the point you've chosen is EXACTLY in the middle, I'm not sure what point would be chosen. It would probably tear a hole in the space/time continuum and such your machine into a black hole. :-)

Peter,
It depends on what the consuming application chooses to use as the basis for the building location. You are correct that there's no coordination check between the Postal Code and Lat/Long coordinates.

I know that GBS consumes the Postal Code, IES consumes the Lat/Long. Not sure about Trane Trace or Carrier HAP.
