Thank you so much Sir. And I am curious that what if I have a glass wall? I was trying to treat it as a window (without inputting a wall for the same position in the previous step) but I am not sure about its building surface name. Appreciate it!
Hi! Thank you for the feedback. It won't work this way. You have to model a wall (surface), and associtate a window (subsurface) on this wall. You can make a very big window (around 99% od the wall's area). That way you can have a glass wall.
@ Got it! Thank you for the advice. Your tutorials are insightful and helped me a lot😀
I learned a lot from your videos! Thank you very much! I would like to know what items need to be entered if I want to simulate a green roof on a building and include plant related data?
Thank you so much for the content it is very useful for me But I have a query if we use a project file from REVIT and export it to OPEN STUDIO, do we have to enter the X,Y,Z axis coordinates in ENERGYPLUS?
Thank you for the feedback. I know that are some tools to import geometries from BIM to OpenStudio, but I am not totally familiar. What I know is that this process is still not 100% accurate and can propagate errors and gaps in the model. Because of this, I still prefer to model everything from scratch in OpenStudio.
Hello Thanks for posting videos, just a small suggestion for the upcoming videos; that the beginning and ending sounds are really loud and make much discomfort while listening to the tutorial via headset. it would be great if you lower the sound of music (tone) at the beginning and ending .
Thank you for the feedback :)
Thanks Dear its very informative for us
Thank you very much for your efforts, your videos are very helpful!
Thank you so much for your course. I when through every single level with you and i must said this journey was incredibily rich for me. I didin't know where to start and now, i've almost finish my project. Looking foward to wach others videos from you.
Hi Matheus, thanks for video. From video Part 3 (min 4:37), Wall North TZ1 is (0,4,3), (0,4,0), (4,4,0) and (4,4,3). However in video part 4 (min.0:47) it is (4,4,3), (4,4,0), (0,4,0 and (0,4,3), I guess it is seen from outside of wall. Please explain which one is correct? and how to coordinate floor and roof, from which direction does it see? many thanks
Dear Matheus, How should we consider model the inside doors? For example the doors between The livingroom and the bedroom.
You have to model the door as a subsurface (Fenestration surface) in one thermal zone (livingroom) and identically in the other thermal zone (bedroom), and then, match both subsurfaces together by setting the "outside condition surface" of each as the other subsurface. Let's say that the door is modelled in subsurface on Livingroom as "Door-Livingroom" and on bedroom as "Door-Bedroom", then you have to set the outside boundary condition og the "Door-Livingroom" as "Door-Bedroom", and the outside boundary condition of the "Door-Bedroom" as "Door-Livingroom".
@@matheusgeraldi Thanks for the clarification. However, I have one more question: what about the shading surface? How should we model it? Is it the same as the ceiling, or are there any differences to consider?
@@isaquesoares6600 It is not the same. You have to use the object class "Shading:Building:Detailed" in EnergyPlys. It is very similar to "BuildingSurface:Detailed" in terms of how you describe the geometry, but the software understands shadings as objects "without temperature", so there is no radiative heat transfer between shading and other objects.
@matheusgeraldi Thanks again for the quick response. I have one more question. Do we need to create a separate thermal zone for the shading in the video example? In the ceiling example, we had to associate it with both a space and a thermal zone. Should we do the same for the shading? If so, would this new thermal zone consist only of the exterior floor and the shading?
@@isaquesoares6600 No need for creating thermal zones for shading.
I am trying to run a simple model with Ideal Load but it is showing the following fatal error: ** Severe ** DualSetPointWithDeadBand: Unanticipated combination of heating and cooling loads - report to EnergyPlus Development Team ** ~~~ ** occurs in Zone=ROOM During Warmup, Environment=RUN PERIOD 1, at Simulation time=01/01 00:03 - 00:06 ** ~~~ ** LoadToHeatingSetPoint=NAN, LoadToCoolingSetPoint=NAN ** ~~~ ** Zone Heating Set-point=21.00 ** ~~~ ** Zone Cooling Set-point=24.00 ** ~~~ ** Zone TempDepZnLd=NAN ** ~~~ ** Zone TempIndZnLd=NAN ** ~~~ ** Zone ThermostatSetPoint=21.00 ** Fatal ** Program terminates due to above conditions. Any idea what maybe causing this issue? I have only one zone and have rechecked all building surfaces again but can't figure out what's wrong!
Hi! It is really hard to find an accurate response for this because it really depends on your model. It seems that you are lacking using the setpoint... are you sure that you are using it correctly?
@@matheusgeraldi Hi, Thank you for replying. I believe that I followed everything correctly from the tutorial. I have set up a schedule, a light load and also set up the thermostat to set temperatures of 21,24 (Heating, Cooling respectively). One major change is that I am using Conduction Finite Difference as Heat Transfer Algorithm as I am trying to model a Phase Change Material in the wall. I can't really seem to figure out what might be causing this error, any lead would be appreciated. Thanks
If you specify an non-symmetric surface (example concrete 10 cm and then insulation and then 0.1 cm of concrete ) how do you know where will the concrete side of the surface will face ? how do you deal with this with indoor walls ? for example in Wall_East1_ZT_1 and Wall_West_ZT_2?
Hello, if I want to simulate a building with multiple floors, and each floor has exactly the same layout of thermal zones, can I use the created thermal zones directly? Or do I have to create thermal zones for each floor even if their layout would be the same?
You can simply model the ground floor, one "typical" floor, and the last upper floor (roof), and then, multiply the results of the typical floors by the number of floors you have. It is not perfect, but it is a valid approximation.
@@matheusgeraldi Thanks for your advice, however, excluding the method of multiplying directly, if I want it to have a relatively accurate value, does that mean I should create thermal zone and wall coordinates for each floor (Same x, y coordinates but different z coordinates)?
@@DZ-tb7hk You can do that, but trust me, it is very accurate using the multiplying approach. It won't be accurate if you model the surroundings of the building (other buildings, for example), because then the shadowing of other buildings will be different for every floor. Otherwise, it will work nicely and smoothly. ;)
thx for the video! But I have to say that the coordinates system seems a little bit confusing😢
Yes, they are. But there are workaround solutions that! Unfortunately, they are paid solutions.
Great videos! Just a question, is there a way to quicken up the zones and especially surface (windows, floors, walls, ...) generation? Here is an example of three room but if we have, for example 100 rooms, it would take ages to complete it.
Thank you. Great video. Is there a way to easily visualize the geometry I am creating to check for mistakes?
Yes! You can use OpenStudio SDK for that.
Your video is very clear! ! Thank you! ! !😄
Hi dear Martheus, thanks a lot for sharing these videos. I have a question, if we design a structure in three floors, if we are going to equip this structure with solar cells, how can i calculate the amount of produced electricity energy per meter? The structure area is 3000 square meters.I am an urban planner and I don't have knowledge about BIM or other related software products
Hi Mehdi, thank you for your feedback! I am planning on upload more videos regarding this topic, but for now, something that can help you is this website: www.pvsyst.com/
@@matheusgeraldi Thanks a lot
I have an error "Warning ** GetVertices: Floor is upside down! Tilt angle=[0.0], should be near 180, Surface="FLOOR_BEDROOM", in Zone="BEDROOM" But I can't understand what's problenm, can you explain this for me
Thanks for the video. Can you clarify something for me? I am confused about co-ordinates. As per the co-ordinate axes shown in the drawing it seems like y-axis represent height (3m). If y axis represent height then won't the coordinate of north wall of living room be (4,0,-4), (4,4,-4), (0,4,-4) and (0,0,-4) ? And also, to define Wall_East1_ZT_1 do we have to set outside boundary condition to zone and outside boundary condition object to Bedroom?
Hi! Thanks for your feedback. Actually, the coordinates are like this: (y,x,z), so the "z" axis is actually the height. You are seeing the floorplan from above (as if if was a piece of paper). So, x and y are on the plane of the "paper", and z is coming out from the paper, making it the height. regarding the Wall_East1_ZT_1, you have to set outside boundary condition to the Wall_West1_ZT_2, from the Zone 2.
Please Make a video for BIPV and Thermal simulation on energy plus , it would be really great.
nice work bro. learned a lot. cheers!
I'm following your videos. In this part i have a problem. When i importing .epw file in excell and try convert text to column i says we have feature loss. After it when i use it in simulation this error appears: Invalid header line in in.epw --no commas, what should i do?
Thanks for your video, now I finshed this model according to these series videos. It can be simulated, while after this, the Table bottom can't be clicked, and if I click the Variable bottom, it can be oped via Excel but it is empty. Can you tell me the reason? Including the HTML, it also can't be clicked.
Sadly, there are a lot of possible reasons for that. =( Are you sure that you simulation run is without any severe errors? You can also open the .csv file generated in the folder where you are running the simulation.
@@matheusgeraldi Thanks for your reply. I check my model again. It has some problems. And I try to address them, while there is one named the " GetSurfaceData: Construction INSIDE_DOOR of interzone surface DOOR_BEDROOM does not have the same materials in the reverse order as the construction INSIDEWALL of adjacent surface WALLEASTLIVINGROOM", I can't recover it. Could you give some suggestions or Could you meet the same problem and what is you way to address this probelm. Looking for your reply.
Thank you so much for providing a complete outline for beginners. I really wanted to go through something like to start EnergyPlus.
Highly gratitude to you, Man. Thanks a lot.
Very interesting
Thanks for your video, it is useful for me. But I have a question about this model. Now I am doing this model in EnergyPlus, in this model, that wall, inside this model, did I need to create two times? Because the wall belong the livingroom from the livingroom's angle however from the bedroom or bathroom, that wall belong them. I want to know how the EnergyPlus defined this thing?
Thanks for your feedback! Yes, you have to model the surfaces representing this wall two times, one belonging to one thermal zone, and another time belonging to another thermal zone. Then, you have to match all surfaces, and you do that by setting the "Outside Boundary Condition" to "Surface", and the "Outside Boundary Condition Object" to the name of the surface that you want to match. For the example shown in 7:42, you're going to match "Wall_East_ZT_1" to "Wall_West_ZT_2", then simply associate these two walls by their "Outside Boundary Condition"s. Remember that you have to do that on both surfaces.
can I measure the carbon emissions of a building using EnergyPlus?
Yes, you can! You just need to input the energy conversion factors of the energy matrix of your country/region to the energy consumption.
Hi bro very nice video. I want to ask if i want to start a new file from scratch, how would i do it? Can you make a video on that
Helps a lot! Thanks!
Thanks a lot for the video and please advise me from where can I get the ISO PDF file?
Thank you for providing these videos. I have a specific issue about the detailed construction of the building. The building models are not included in the videos, making it difficult for me to replicate the entire structure. If you permit, I would want to provide you the building's 3D model or a photo including the necessary construction details.
ERRATA: I mentioned ISO 10453, but it's actually ISO 10456!! Sorry for that!
Hey, how do I add a class to the Class List?
I cannot search the ISO 10453, may I ask what is the title of the code?
It's actually ISO 10456! Sorry for that.
