OpenStudio SketchUp - Data Visualization Measure

In this video we will introduce a custom measure, View Data, that can be downloaded from the Building Component Library. This measure allows you to overlay output data onto your model geometry. It is good for visualizing surface parameters such as temperatures, radiation, heat gains, heat storage, etc. Transcript: Today we are going to take a look at a measure that you can download from the building component library. It allows you to visualize certain output variables. The variables will be overlaid on the top of surfaces in your model. We will be looking at the temperature of these surfaces. This surface on the roof. We will take a look at what those temperatures are (during the simulation). Let us go ahead and launch OpenStudio. Go to the measures tab. It is going to be a measure that you can download from the Building Component Library. Go to components and measures, find measures. It is located in the "Reporting" category. Do a search for "view". It is this measure right here. View Data. You can see I already have it downloaded, but you would just check this box and click download. It is going to be located in the reporting category...so let us select...Oops Let it update first. Select the reporting category QA/QC. It is located right here. We will drag this measure in here. Select it. You can see that there is a number of inputs that are associated with this measure. The model source: you can use it select either the IDF file or the OSM file. The OpenStudio file gets proofed by EnergyPlus and sometimes the surfaces in the OpenStudio file will get modified or changed; to fix errors. They will eventually get be passed on to EnergyPlus in the form of the IDF file. So, that is the difference here. We will just leave it at OSM for now. Reporting frequency: this is the frequency of the output variables that are reported. It can be reported in hourly steps or in the time step that your model is simulated in. We will leave it at hourly. That should give us enough information. You could change it to time step. Time step is located in the simulation settings area. That is this number right here. The actual time step this model is going to be in 10 minute increments; 60 minutes divided by 6. That is going to be a lot of data, so let us just keep the time step set for hourly. Next, there are three variables here that you can input. You can track these output variables. Outside Face Temperature, Inside Face Temperature, Zone Mean Radiant Temperature. You can find these in the input/output reference manual. These are going to be the variables; output variables for surfaces. These are associated with those those surfaces. You can select any one of these and copy and and paste it into these fields here. Let us leave these as default for now. Let us go ahead and run the simulation. The simulation has completed. Go to the results summary tab. Up at the top left let us select view data. Up at the top right we are going to select render by data. If we scroll down you can see all the parameters that we can adjust. Right now we are viewing the Surface Outside Face Temperature. You could change it to some of these other parameters. But let us continue. You can change the color scheme...the way it is displayed. We will just keep it at diverging. For cold temperatures it is going to be blue and then for hotter temperatures it is going to be red. Moving on...you can change it to any day of the year. Zero being the 1st of January and then all the way through to December. If you put it in the middle, here, it will be somewhere around June or July. That is going to give us the most extremes in temperature between night and day. Here you can change the hour of that day. You can adjust those up and down. This is just how you want to rotate the bar. These two parameters go together; this allows you to cycle the hours throughout the day. This will speed up or slow down how fast it cycles. We are going to put it right about here. We will just click cycle. You can see how it plays throughout all 24 hours of the day. You can see that in the morning this side of the roof heats up and then the in the...let us see...in the morning it heats up on this side (East) and in the afternoon it heats up on this (West) side. Let us take a look at...let us hide the wireframes. We are just going to pause this. Let us hide the solar panels. You can see that this is all one surface. With those solar panels...they should be affecting this roof. This is one surface. It is not showing us the effect of those solar panels. It is taking the entire surface average and it is plotting that as one color. ... Complete transcript: https: //www.helix-engineers.net/technical-articles
