What software do I use to get 10/15 minute interval data (different parameters of the HVAC system and the energy consumption in that 10/15 minute interval) of a HVAC system?

Hello. I'm working on a Machine Learning problem where I need to train the model to calculate the energy consumption of an HVAC system under specific conditions (both controllable parameters such as the flow rate of the coolant and uncontrollable parameters like temperature and humidity outside and the setpoint temperature). I found the following dataset that is close to what I'm looking for which was simulated using OpenStudio, but I couldn't replicate this for Indian conditions and I ran into some version dependencies. I don't have a background in HVAC modelling and I come from a CS background. So forgive me for any mistakes in the terminology. I would greatly appreciate it, if you could point me to some software or an existing dataset that helps me to achieve this.

Ad simulation step - you can specify the Timestep parameter in the idf file. If you just want to generate data, you also need to change output variables specs. In example

Output:Variable, VAV_1 Zone Equipment Outlet Node, System Node Pressure, timestep;

Ad Indian conditions - all you need is to supply weather (epw) file and make sure this file is used. Configurable in idf. Should work out-of-the-box.

Ad simulation - I am using E+ for similar purposes (control, ML). I recommend to wrap E+ with launcher (e.g. using energyplus executalbe) and PythonPlugin as interface for getting state and resetting setpoints (actions).

Hi. Thank you so much for your response. Is it possible for me to DM you? I have some more doubts about using EnergyPlus for Machine Learning purposes. It would be great if you could help clear them.

EnergyPlus offers several sub-hourly output options. Other softwares may also do this (but I'm not familiar with them)
