This is a photo I saw on Twitter of Arrowhead Stadium, the home of the NFL's Kansas City Chiefs. This is very similar to the system used beneath golf greens today. Cool water or warm water can be pumped through this system the will cool or warm the root zone depending on the time of year. It is very simple technology provided you are willing to pay the expense of heating and cooling the water and also have an adjacent structure to house the water heater/ condenser unit. Every year during the Masters, this technology surfaces because it was ANGC who created the initial system. I am personally not aware of any other facility that has this below their surface and imagine it's more popular among athletic fields, where power is readily available and the surface area is manageable.
