Re: Graph of hourly and daily models?

To determine efficiency you also need to know the amount of conditioned space. My intent is more to determine the accuracy of results against something that can be measured (like actual cooling energy).

Interesting.  I've been curious about what else besides M&V the CalTrack models could be used for.  For example if you had heating, cooling, and baseload parameters, could you use that to compare across different buildings to determine which ones are more or less efficient?  Is that what you were thinking?

The hourly models don't provide as straight-foward a means of disaggregation, as they construct separate model parameters for different temperature bins. So unlike the daily models where there is a single "cooling", "baseload", and "heating" coefficient, the hourly models have coefficients across up to 5 temperature bins. Additionally, the coefficients are different for each month.

Thanks for letting us know.  

Yes, I agree it would be nice to get energy use by category, but how do we get that information?

Just my opinion, but I think a chart showing the hourly energy usage in three categories (base, heating, cooling) would be more useful than all the different model parameters.

Glad to hear it! Unfortunately, I haven't yet had the chance to build visualizations for the hourly model. There are a few challenges that make this a little harder than with the daily models. 1) There can be up to 12 separate models for 12 months of data 2) there are way more independent variables and parameters to visualize. It will certainly be possible to make nice visualizations but it will take some effort or a dedicated volunteer to help us get these across the line.

Hello,

We're almost done with our openeemeter integration.  We were able to generate a nice plot of the daily model based on the tutorial.  Is it possible also to generate a plot of the hourly model?
