Thank you for the well explained video on shading. Would it be more appropriate to change the building overhangs as shading surfaces, rather than adding the additional overhang shading element? As you have added the shading overhang suffices for the purposes of instruction.
thank you for the good teaching, can i use the temperature variant transmittance or emissivity? i want simulation for the thermochromic materials, for example, window
Thank you. Good question. Yes, you could simulate thermochromic windows by applying a shading surface over the window and then assigning an 8760 hourly transmittance schedule. The transmittance schedule could be precalculated csv file based on the TMY weather data and then imported into OpenStudio using the import interval measure as discussed here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-S_HbjEAGCrg.html Alternatively, you could write an OpenStudio or EnergyPlus measure that inserts the WindowMaterial:GlazingGroup:Thermochromic object and its associated WindowMaterial:Glazing objects into your model and assigns the GlazingGroup as a material to your window/s. Here is the InputOutput reference: bigladdersoftware.com/epx/docs/8-0/input-output-reference/page-010.html#windowmaterialglazinggroupthermochromic
Hello! I am trying to change the Shading Surface Type, bit this field os blocked at my model. How can I change a building Shading Surface to a Site Shading Surface from other way? Could I simulate a tree as a Building Shading Surface? Another doubt, how can I do the transmittance change schedule Shading Surface on Energy Plus directly?
Building and site shaded surfaces should be purple. The space shading surface should be blue. You can change the building and site type using the OpenStudio app: Facility tab, Shading tab. You can change the space type using the OpenStudio app: Spaces tab, Shading tab. You must create the space shading surface while editing a space. If you want fixed solar transmittance, create a fixed fraction schedule and assign the schedule as shown in this video.
I do not, but Neil Bulger has a good video about it: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-WFbkAOUgDks.html I talk a little bit about glare controls for blinds in this video:ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-85oiYQzT72Q.html
Hello, I added a transmittance schedule for the shade tree in OpenStudio, but the simulation results did not change compared to the no schedule. May I ask why?
EnergyPlus does not make openstudio files. You will have to open up the OpenStudio app. Then, go to file, import, IDF. Then, you can save it as an OSM file.
