I used the following measure: https://unmethours.com/question/28814/ground-temperature-in-openstudio/ code posted by https://unmethours.com/users/13223/iswarya-m-mohan/ to set the ground temperature to a user specified value. I confirmed in my timeseries output data that the value was indeed what I had specified.

I used the following measure: https://unmethours.com/question/28814/ground-temperature-in-openstudio/ code posted by https://unmethours.com/users/13223/iswarya-m-mohan/ to set the ground temperature to a user specified value. I confirmed in my timeseries output data that the value was indeed what I had specified.
However, my goal of changing ground heat transfer into the building by inputting a user specified Site Ground Temperature did not work. This is because my models are using Foundation Kiva to model ground heat transfer, instead of some other algorithms available.
Foundation Kiva calculated heat flow into the floor/wall (surfaces with "Foundation" Boundary Condition) is not impacted by Site Ground Temperature.
If my floor/wall surfaces had "Ground" Boundary condition instead of "Foundation" Boundary Condition, perhaps changing the Site Ground Temperature would impact heat flow.
