Similar to the engine feature comparison (and for the same DOE document!) I am trying to crowd source some information about time spent on different modeling tasks. I created this Google Spreadsheet for this purpose. The tasks I am interested in are:

  • Creating a post-design LEED model
  • Creating a design model for a new building
  • Creating a calibrated model for an existing building.

To get some nuance in the data I am looking at three different building types (office, hospital, and home) and distinguishing between a conventional building (i.e., a few or no ECMs) and a high-performance building (i.e., many ECMs).

If you have some experience here, please create a row for yourself and enter typical values where appropriate.

If you have any suggestions about the structure of the spreadsheet please make them here. Thanks.

I'm thinking this might be a little hard to fill, especially for office. I'd say the size of the project matters (sqft), at least for the geometry creation. For HVAC, number of zones and number of systems will definitely affect the time required too.

Maybe we should refine each "building type" a bit. We could take the commercial reference buildings for example.

I'm thinking much the same as Julien.

  • Size is a secondary criteria because you can often combine multiple similar systems into a single system in the model, but it's helpful to know.
  • I'm not sure how to define the difference between "Conventional" and "High Performance"
    • For the calibrated model, should we assume that the modeler is starting with no prior model? that construction documents are available and up-to-date?
