What are the key technical challenges and design options for optimizing a geothermal heat pump design? Review the pros and cons involved with centralized or distributed pumping, with hybrid or decoupled systems, and with the controls that can guide them.

With the help of advances in intelligent controls and a shift in design mindset, these systems can steer buildings toward smaller equipment sizes and associated savings. Review three projects and consider the benefits of keeping an upcoming project in the loop.
