About this course
This course will be delivered in two parts: Lecture during module 1 will provide the background and tools students need to complete an entire design exercise on their own for homework. Module 2 will address all questions from module 1, plus all of the tough but important details that determine the success of standing column well systems in the real world. This is a self-paced course - students are not expected to be 'logged in' at any specific time.

Module 1 • 6 assignments
Fundamentals of Standing Column Well Geothermal Systems
TOPICS COVERED: A look at what's unique to these systems as opposed to the more common closed loop approach. What's happening in the well as water is circulated between the building and the ground. A progression from cylindrical steady-state heat transfer to transient quasi-steady state implementation. Measurement of thermal conductivity, diffusivity and relaxation characteristics of the well. A look at a SCW installation: drilling techniques, HVAC Hardware, and controls.

Advanced Standing Column Well Design Training
TOPICS COVERED: Unlike closed loops, open loop systems require extension into the mechanical room for heat exchange...towards a turnkey system. HVAC system performance hinges on EWT to the heat pumps and parasitic power used to transport heat. Addressing the time dependent elements of load, SCW temperature, heat pump operation and parasitic power over extended periods. What's the payback on the net capital outlay? We'll conclude by considering potential regulatory issues.
