OpenStudio: What do I have to do to make muy building affected by the exterior temperature?
My building does not appear to be affected by its surroundings, despite having set high infiltration values (ranging between 0.5 and 0.005 floor rate per area). Additionally, the building has no insulation, as the walls are composed of 2 cm of lime mortar, 19 cm of ceramic brick, and 2 cm of gypsum mortar. No ventilation or HVAC system has been implemented, yet the building seems to remain perfectly insulated even under extreme weather conditions, such as 44ºC in summer in Barcelona. The indoor-temperature is never higher than 33º meanwhile the outdoor-temperature is minimum 34º.
I am struggling to understand this issue, and I have an upcoming deadline to provide accurate simulations. Does anyone have any insights?
@mariacanoteixido24 what simulation tool are you using? Please mention it in the title or body of your post, as well as add a tag so that others can provide better help.
Also, can you upload your model to Google Drive, Dropbox, etc. and then share a URL for others to download? That would help others provide better solutions.
Certainly! I completely forgot to mention that I am using OpenStudio to design the building and EnergyPlus to run the simulations.
Below is the link to my Google Drive, where you can find the (.osm) and (.idf) files, along with the weather file (.epw) and two Jupyter Notebook files (.ipynb) used to run the simulations and generate various indoor-outdoor temperature graphs. I'll try later to post the link so you don't have to ask for permision to check the files. Here's the link https://drive.google.com/drive/folder...
@mariacanoteixido24 it looks like the Share settings in Google Drive or so that people have to request permission. If you change that to "Anyone with the link can access", that will make it easier for others to review your files.
Have you looked at the output variables for the infiltration object? Maybe you are misinterpreting an input and getting much less infiltration than you expect.
