Hi @obuchely. If you're referring to the OpenStudioApplication (or App), then you're correct: one cannot edit ground temperatures or activate Kiva using the App. To reset ground temperatures, there's a simple hack described here. @Jamie Sullivan is rightly pointing to superior solutions, but there are (rare) circumstances where even Kiva won't be of much help (unless this has changed recently). In such cases, you may need to fallback on resetting ground temperatures by hand. To ~safely reset ground temperatures, there's a simple hack described here.hand.

There is a step-by-step Measure approach to deploying Kiva using the App, as described here - should . Should work for most cases.

Of course if you're familiar with the OpenStudio SDK (or API), then you can script your own solution based on a handful of classes (e.g. here and here). Here's a very straightforward example, example in Ruby and in Python.
