BCL no longer seems to include residential measures. Please advise how these might be added.

Indeed we deprecated the residential OpenStudio measures. This was a difficult decision, but they proved to have some significant problems. In theory, OS measures are supposed to be able to run independent of each other. However, due to the nature of these measures it was necessary to run them in a specific sequence because downstream measures often depended on the results of previous measures. It also meant we had to pass and track a lot of metadata down the measure pipeline. In addition, the measures incurred high development/maintenance costs and were slow to run.

To solve some of these problems we have migrated the capabilities from those measures into a new single measure (available at https://github.com/NREL/OpenStudio-HPXML). This takes a simplified HPXML description of a house and builds an OpenStudio model from it in one step. It ends up reducing the possibilities of errors in sequencing measures incorrectly and also reduces edge cases where measures are used in unanticipated ways. The measure also has far more capability (in terms of the residential technologies that can be modeled) and the workflow runtimes are significantly faster. The measure is already being used as the basis for BEopt, Home Energy Score, ResStock, and ERI calculations, among other projects, and is used by several third-party software developers.

Note that while you can generate the residential HPXML file any way that you want for use with the above measure, there is also a single OpenStudio measure that generates the file from inputs similar to the previous residential measures.

An archive of the previous residential measures can be found in an older version of ResStock here.

Hi @shorowit,

I am planning on doing some energy modeling of a large residential building stock for a local authority in the UK and am hoping to do this in OpenStudio/EnergyPlus. I have downloaded the HPXML zip file but I am not sure how to use this in the OpenStudio User Interface. Is there a way of simply importing the measures when in OpenStudio?

Thanks in advance,

Jack

Hi sorry my english is not good You managed to use HPXML in OpenStudio-Application, and at the output it will give you the xml file. I need this to later use OpenStudio-ERI, I would appreciate your help
