With the ground heat exchanger, it's not just about pre-cooling but also about "pre-heating" in winter. This saves electricity costs, but overall, it probably is never really economical.
We decided to build a "do-it-yourself" ground heat exchanger. My buddy, who also did the earthworks, basically laid a 200mm KG2000 pipe in the construction pit around the house at a depth of 2.5m. That's about 40 meters. It serves as a supply air pipe and works like a ground heat exchanger. It added a total of €800 extra to the earthworks costs.
I am aware that some are skeptical of this solution (condensation water in the pipe). However, I trust my buddy as an experienced sewer constructor. He says that the pipe is laid with about a 2% slope and that water cannot accumulate anywhere.
