Building modelling in TRNSYS (Type 56) : ASHRAE 2013 Design day as Weather Data for HVAC sizing
Hi,
I have a building model in TRNSYS that I would like to validate with a model I made with Energy Plus/OpenStudio.
To achieve this, I'd like to know how my TRNSYS model behave for the ASHRAE 2013 Design Day (.ddy file) : heating and cooling loads, temperature and humidity profiles. But there's no Type in TRNSYS that allowed .ddy file in the Weather Date Reading and Processing folder.
Is that even possible? If not, how HVAC sizing is done in TRNSYS without ddy-file?
I'm new to building modelling, any help will be appreciated. Thank you,
It’s been a while since I used Trnsys, but I don’t remember using design days. I obtained the heating/cooling load by running the model for all year (using ideal conditions) and I extracted the maximum values from an excel file. Then I designed the HVAC equipment based on those maximum values.
