What's New in the 0.3.0 OpenStudio Google SketchUp Plug-in So this is a quick tutorial on the new features of the 0.3 version of the OpenStudio Google SketchUp plug you are seeing the new toolbar up here a lot of new icons a lot of the same functionality but I’m going to highlight some of the additional functionality down here you are seeing a modelcreated in the old 1.0.5 version of the SketchUp plug in and what I wanted to highlight here is looking from this perimeter zone to the core zone is that you don’t see through what we’re seeing all of our surfaces are heat transfer surfaces that represent heat boundaries we think of those as walls and in some cases like on the exterior that is a physical wall and the roof is a physical roof but these walls here that are interior surfaces in this case just are an air wall an imaginary zone boundary that does represent a physical wall in the building and we don’t differentiate the way those look from the physical walls which makes this tough to use as a design tool and there are some other benefits once we address so what I want to check here right now those are still outdoor boundary conditions but if I run surfaced matching now they are interior switch my rendering mode back I still can’t see through but when I need to do is to go to my default constructions and now pick interior walls change their construction to air wall apply that to the model and I now have see through walls so I can see through just as I would in real life we use a light checkerboard pattern instead of making them clear so that you can see them and so they are selectable but um now we can see that the building and more importantly or as important if we use of radiance to do daylighting we can tell radiance to ignore those air walls and let light pass from the exterior of the building through to the core zone which will help a lot now so we have now allowed to physical zone boundaries that don’t represent physical walls and show that but there is still one more piece missing we have physical walls in this building are not zone boundaries and we now have a new tool that allows those to be put in again as a design tool and also to allow daylighting analysis to interact with the real geometry of the building these interior partitions will get constructions just like just like the heat transfer surfaces because those constructions will be used so that radiance or other programs will know how light it interacts with them I’ll show you in a minute there is an additional byproduct positive byproduct of having a construction zone so we are just going to draw what looks like a cubicle it’s not very exciting but it will show the idea so I now have a cubicle sitting all itself in this building and and let me get rid of my section well we will leave it there for a minute I’m trying to hide my section cut and I forgot my shortcut lets go to hide the section plane and this will look a little nicer so we have a green color for these there is a front and back which have different materials applied depending upon what your construction that could be drywall and drywall they could be um anything you want so when I pick one of these surfaces and look at it in the object information window it has a construction it has a name what we can do now is to is to convert this to an internal mass and what that will do is not the physical geometry but an internal mass represented by that to EnergyPlus for the simulation and so just as a physical wall somewhere else that is a boundary a zone boundary can store energy internal mass in a zone can store energy as well and this brings up another good point here I’m going to delete my section cut so that we can see our whole building again lets turn it back on so we have now added objects here that are beyond what EnergyPlus can store in an IDF file so the new version of the plug and you can export to an IDF or import an IDF but our safe format is now an OpenStudio model so when you go to save my little pop up should come up here but it was already saved anyway so when you and save as OSM is the new format for OpenStudio model and that will allow you to re-open this and still see your interior partitions if you had instead exported as an IDF and re-imported that internal mass object will still be around but you wouldn’t be able to see it or select it and the geometry wouldn’t be there so the OSM will be the format of choice to use for that
