Lower zone air temperature
Hello
I am currently modelling an existing house using sketchup and openstudio, i am a bit new to this but have applied all the data and run my model and i have seen the results. However, the Zone Air Temperature for some of my thermal zones are way too high (In degrees Celsius), i was wondering what i needed to adjust in the data i have put in openstudio to get lower zone air temperatures. I tried adjusting some of the definitions but i didn't get that much of a difference. Note: I still havent added thermostats or Infiltration Air Leakage, i wanted to ensure that my house was at an OK air temperature before adding air leakage and thermostats. Does that seem reasonable?
If you aren't providing any outside air (either infiltration or mechanical ventilation) to your zone, then the internal loads will drive the temperature way up like this. All buildings are leaky, especially buildings that have been built already :)
Oh okay! Also- for infiltration, do i add it in the spaces or space types? Thanks so much by the way!
Always at the highest level of inheritance that you can use: https://nrel.github.io/OpenStudio-use... This minimizes the number of hard-assignments you have to do. Eg:Do it at the space Type level: so pick what represents the majority of the spaces that are of that space type, and only modify the spaces that differ.
