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

Indeed we removed the residential OpenStudio measures. They haven’t really been under active development for a while. This was a decision we went back and forth on. 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 depend on the results of previous measures. It also meant we had to pass and track a lot of meta data down the measure pipeline.

To solve some of these problems we have migrated the capabilities from those measures into a new single measure (under development 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 our work for DOE’s Home Energy Score, DOE's Weatherization Assistant, and the Energy Rating Index calculation, among a few other projects. We expect a release of the measure with documentation in the next couple months

Note that while you can generate the residential HPXML file any way that you want for use with the above measure, we're also planning to create an OpenStudio measure over the next year that generates the file from inputs similar to the previous residential measures.

In the meantime if you just need access to the previous measures for your work, they are still being used in ResStock. You can find the latest version of them here. We are planning on deprecating their use and moving to the HPXML workflow for that project next year.

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
